My wife liked Tom Selleck so it was required watching. Not on the level of, say, 2001 A Space Odyssey, but pretty neat little gadgets. Most of the movies panned by the critics were mostly pretty good, IMHO.

Workshop Straight 8 status
by David Gesswein 29 Aug '19

29 Aug '19

When I left after the last workshop a bit would be dropped when shifting the accumulator in the moving lights demo. I was able to move failure to a different AC bit by swapping AC cards. When I got to Infoage for this workshop Evan said that he had successfully ran the moving lights program for a demo sometime previously. I spend some time trying to get the problem to reproduce unsuccessfully. I tried wiggling the cards and using the margin check voltages without causing the failure. Moving the cards enough that they move in the backplane connector would cause faults but motion less than that didn't. I suspect it will be back sometime. At a previous workshop I replaced a number of diodes in the memory cards but didn't' have time to do the memory margin check procedure. This time the sense amp margin voltages that caused failure were 4.9V and 17.3V. The manual says the difference should be > 12V which it is. The slice failure voltages are 7.04 and 8.1V. No minimum range was specified in the maintenance procedures. I left the slice voltage set to the middle of the range at 7.6V. Power supply voltages were 10.7 and -14.6. I did notice that I was still getting double increments on front panel load/store operations occasionally. The machine has a debounce circuit that did not debounce sufficiently. I assume the switches are noisier than when new. I previously put a 47uf capacitor on it to increase the debounce time. I increased that to 100uf. That may be getting a little too large since it seemed to ignore really quick switch presses. People using the machine should let me know if you see the double increment or other funny behavior still and if you find it ignores switch actions for you. Good check is after or occasionally during check the address matches the expected address for next location you are loading. When I tried to local Focal programs last time I got ?11.35 error which is input buffer overflow. Focal has a design issue. When loading from ASR33 paper tape it prints what it reads in without any flow control so if printing is slower than reading it will overrun when the small buffer is filled. I compared the RX bit timing from the teletype to the TX clock and the TX clock was slower. I adjusted the R450 clock to prevent the overrun. Teletype seemed to be happy with the faster clock. I was able to load lunar lander without errors. My attempt to land ended with a crater. Known issues are 1) The machine will start running sometimes at power on when the auto restart switch is off. It seems to start running before the voltages are stable so it corrupts memory when it runs. Didn't look at this. Easy workaround is to leave the single step switch on at power on. 3) The W300 delay line cards still need to be fixed. I think the machine is usable for demos. I suspect sometimes the demos won't work but will next time. We need to keep track of what issues we see and is anything correlated with when it acts up such as temperature to help in further fixing. I left it with the moving AC light demo, the punch block letter text on paper tape demo, and FOCAL lunar lander demo. I'll look for what else might be of interest. Getting the plotter working and making an interface on it will hopefully be a winter task for me. Having the plotter making some interesting plots should be a good background demo.

August Repair Day - Sat Report from Member
by dillera＠gmail.com 28 Aug '19

28 Aug '19

Ok, the Saturday Repair Day was a blast. Here are some photos and notes from the show. A lot of people showed up, a lot of projects got done and we had a wonderful evening barbecue outside as well. If anyone took a photo of that, please pass it along, I was too busy eating and drinking to take any photos. We had a couple of new members show up and it was a nice time getting to know them during the day as well as over food. Some equipment was given away and some new donations to the Museum also. Photos I took are here: https://imgur.com/gallery/X2o83iM <https://imgur.com/gallery/X2o83iM> Items to consider- 1. Serial box. JasonP's amazing serial box (Smart Cable SC821 Plus) let me connect the MicroVax to a VT term- without it i wouldn't have had the proper cabling to do it. This is a buy from me. https://www.smart-cable.com/catalog?action=display&key=102 <https://www.smart-cable.com/catalog?action=display&key=102> I've found it on ebay for $10-50 (just got one on ebay w/ cables for $40). 2. Pencil Soldering iron - this looked amazing and i didn't take a photo so if AlexJ can comment on what that model was I want to get one. It looked very handy for some jobs. 3. MFM Emulater - DaveG was kind enough to help me image a drive and showed me his amazing MFM drive emulator. I now have one in my Vax... Please reply back if you are interested in an October and November Repair day so we can ensure we have one! -andy

Problems we face as collectors/curators: The last lesson of Bob Pease
by Herb Johnson 26 Aug '19

26 Aug '19

Yes, this post is too long. Read it when you have time, if you have interest in analog electronics. Or, if you think about problems in collecting vintage technology from others' "archives" (spelled "hoardings"). https://www.electronicdesign.com/analog/what-s-all-pease-prototype-stuff-an… (link to previous article below) https://www.electronicdesign.com/analog/what-s-all-stuff-stuff-anyhow One of the electronic trade-magazines (papery bloggy things in postal mail to oldies) occasionally sends me email-links to articles on their Web sites. This article caught my attention, as it represents the problems we have today as collectors of vintage computing (or electronic, or semiconductor) items. It's the perception that this stuff is junk and has no value except as curiosities accumulated by "hoarders". But I'll explain why this stuff has value. If you read the article, it's about a collection of accumulated artifacts of work done by Bob Pease, an analog design engineer at Philbrick National Semiconductor in the 1960's and decades following. Since he worked before digital simulation - and because simulation isn't good enough - he accumulated many prototype circuits for things he designed. a reminder: prototypes prove the result. So they were necessary at design-verification time, and later to deal with problems in production. He also found them useful to demonstrate to others, and to show when National was exhibiting. Bob's contributions were not only in design and development, but in education and in publication. His columns (and books from them) on analog design were amusing, informative and are read to this day. He personally mentored a generation of analog electronic designers. Bob Pease died several years ago. However: the article is informative about attitudes about previous design and prototype practices; or simply about the technical past. The article essentially suggests: "This stuff is a mess of junk. We don't do things this way now, we know better now. There's no value to this stuff, because we don't know how to make sense of it. Since some parts are before production, they can't be of any interest to anyone except as scrap. A few things, remind some of us about the-old-days. But this guy was a hoarder." There's a link to a previous article of a few months prior (link above). The "Pease collection" was obtained from Pease's estate, I think in 2017. The task of organizing it was "resigned" to a "media relations manager" - very likely a person who was unfamiliar with its technical content. As with the current article, other engineer's comments and photos give some meaning to the items photographed. Nobody seems to know exactly what to do with this stuff, other than to give it away to their older buddies at social events. Of course, any collector of vintage semiconductors will wince when reading this article: they love pre-production parts. And many "senior" analog engineers, like the ones quoted in the articles, have some experience with the chips and circuits shown, and the methods Bob used in design and construction. Again: they are still informed by his work and methods. Some number of engineers or collectors, would likely be pleased to have some example from their mentor or simply from the period. I won't give a lecture on "curation", the art of displaying and describing artifacts to glean information and context and to preserve intellectual and/or physical content. That describes a process that has yet to be performed (may never happen) for this rescued but endangered collection. It's already picked over a few times. For those who are simply vintage-computing collectors or users, you'll likely be saddened by association about this article and situation. It could well be a bunch of vintage computers and accessories. Note the author confuses a 5.25-inch floppy drive with "a CD player". If that kind of iconic artifact is unrecognizable in 2019, imagine what will be overlooked going forward. The last lesson of Bob Pease, may well be as suggested in the title of the article: "What is this stuff, anyhow?". What's to be done - if anything - with artifacts of technical work and products? Do they have value? What do they mean? Can they inform us, or simply amuse us, or do they just get in the way? Regards, Herb Johnson -- Herbert R.

by Sentry TV 23 Aug '19

23 Aug '19

Just a reminder I'll be at the workshop this weekend Saturday at about 10 AM till about 4PM In case anyone has discs I can use to boot this machine. It would certainly be appreciated. I will be bringing the Xerox machine, Monitor, Printer to the next Saturday workshop. Anyone who has 5.25 boot disk(s) DOS or CP/M that will be going to the workshop Saturday, could you bring a couple to test, please? Right now I do not have any boot disks for this. I had MS-DOS disks at one time but cant find them, yet. Thank you Mike R.

Pick up a MacBook?
by Damir Dzhafarov 23 Aug '19

23 Aug '19

Hi everyone, I’m new to the group. I bought a PowerBook 520c on FB Matketplace a while ago in hopes a family friend could pick it up, but unfortunately, that hasn’t worked out yet. Anyone in the area of Springfield PA who would like to pick it up and maybe play with for a while until we can work out a time for me to get it from you? (I’m in Connecticut.) I’m in no hurry, and wouldn’t mind another vintage computer enthusiast having it for a while. It’s all paid for, so I could just send you contact details for the person and you could work out where to meet (a Starbucks or police station or whatever you’re both comfortable with). Please let know if you might be interested. Thanks.

[Off Topic] - Vintage computers and UPSes
by John Heritage 20 Aug '19

20 Aug '19

Hey folks, just curious For longevity of vintage computers that are hooked up and powered on semi-frequently; I assume any kind of UPS is better than none to try to reduce power spikes, or reduce PSU fatigue from brownouts. I was curious what folks recommendations or thoughts are here? I have a couple of old (~ 15+ year) UPSes that i'm debating replacing the batteries on, and one of them would be for plugging in some vintage hardware. Is there anything I should watch out for? Should I assume these are too old to effectively monitor/protect - or doesnt' that really matter? etc. Thanks! John

[Off Topic] - Vintage computers and UPSes
by Herb Johnson 20 Aug '19

20 Aug '19

I think this subject is on-topic, because vintage computers suffer damage over time due to line-voltage and over-voltage. UPSs can't solve all those problems. But paying attention to the AC power line is important to collectors and users. Shorted tantalum capacitors on DC circuits are a known failure due to both time and over voltage. For example, Heath/Zenith H-89s and H-19s (computer and terminal) expect to operate at 110V AC.T he unregulated side of their 5V DC regulators have capacitors rated at a voltage just below the DC voltage produced - at 110V. When run at 120V or higher, the rated voltage is exceeded and the tantalums "blow". The fix is to replace the caps with higher-voltage devices, and/or reduce AC voltage. That solution won't be found with most UPS. A short-term solution is to use a Variac to reduce AC voltage. Long term, there's step-up/down transformers one can buy for the purpose. Technically-experienced people can make such devices. also: Thank you to Jason Perkins, for his post-link to an article on adjusting a UPS charging voltage. I was aware of this problem but not informed in detail. The article is informative, so thanks! http://www.jjoseph.org/notes/apc_smartups_battery_float_voltage Regards, Herb Johnson -- Herbert R.

Re: [vcf-midatlantic] Pet with 9" screen

Other people's experience may be different, but in my experience, it is rare for a 1970’s era micro-computer schematic to completely match a board, as it was actually manufactured. Component differences and wiring differences are often found, even when comparing schematics that were drawn for a specific version board, to that same version board. You may want to determine how it came from the factory, in order to determine the best course of action for you. Regards, Mike W.

Re: [vcf-midatlantic] AT&T Dataphone - Modem or "Service"?
by Jeffrey Jonas 20 Aug '19

20 Aug '19

Jeff (aka Bags): > ... There was a monitoring service offered as well > (wonders just how much you can monitor a line at 2400 baud) > under the same brand name. My guess: pre-divestiture phone lines were "voice grade": not guaranteed for FAX or data, thus requiring conditioning upon install and monitoring afterwards lest you get crosstalk, static and other interference. Neil Cherry: > I used to use Paradyne 740 muxes to break those out. Ah yes, modem sharing units. A strange kludge: some were "statistically multiplexed" to allow for different speeds, others were round-robin multiplexed, and others merely or-ed all the signals (I used those with software collision detection with per-packet ack-protocol!) > I also recall the Baby Bells delivering a special current loop line > for AP News service (I think it was dry). Those were fun, 28.8 baud. My local library had one of those teletypes clattering out the news. AT&T used to be "American Telephone and TELEGRAPH", thus the data lines! I'm unsure how they competed with Postal Telegraph and Western Union (my grandpa was a telegrapher). It was a sad day when AT&T decommissioned the last telegraph line. I remember the AT&T president saying that they'd remain "American Telephone and Telegraph" in honor of their heritage, but the following president undid that, making the name just "AT&T". Related to that: telegraph lines used to follow the railroad tracks, mostly for the railroad's internal use. Customer telegrams were sent when the lines were otherwise idle. Years later, right of way was a key part for competing phone companies: citing https://www.npr.org/2012/10/15/162963607/sprint-born-from-railroad-telephon… Sprint Born From Railroad, Telephone Businesses Melissa Block explores the long family history of the companies that comprise what became Sprint. It all began in Kansas in the late 19th century and came to include a long distance system created by the Southern Pacific Railroad Internal Network Telecommunications, or SPRINT. -- jeff jonas

I hope that you can talk to Evan, Corey or myself privately and clarify what you are feeling. We do what we can to accommodate volunteers, but sometimes schedules don't line up. You are always welcome to come to a workshop, even if it is only to watch.

There are always other members at the repair workshops that are helpful friendly and willing to teach someone else. You are also invited to Festivus which is December 7.

> thinking i really really don’t belong here. i liked volunteering and learning but seems since there is another girl coming to things, I have been sorta cast aside. I have been told it’s scheduling conflicts, but my schedule issues are the same as always so.... I don't think this should be a list discussion, but since you brought it up, I will reply. Everyone knows that weekends (usually Saturdays), sometimes on Wednesdays, and very rarely other times are when I'm at the museum. For the last year-ish you made it clear that Saturdays/Wednesdays generally do not work for you. My schedule is less flexible as of last week due to my new job (conventional M-F/9-5 although I may sometimes get Wed. for working remotely). You also asked about working in the museum/warehouse solo. Access to the keys and the trust/responsibility of working there solo is reserved senior members who've proven themselves. Also most of the jobs require a lot of knowledge about computer history. There is absolutely no personal reason behind any of this, and all are welcome in our group ... even Corey (back at ya, dude)...

“That’s what I was told, but the reality is that I don’t get called on to volunteer at all anymore and used to be called on every other week or so. “ Not everyone is appropriate for every job that needs doing. I also don’t always wait to be called but will reach out when I have available time and see if any help is needed. Sometimes it’s things I’m not “qualified” to help with!! (Not my area of expertise) “ I don’t feel comfortable going to workshops when I haven’t even been involved. And my knowledge of vintage tech is not as great as my interest, so I rarely can participate in forums.” That one I understand, but that’s also on you too. Involvement and amount of other participation has nothing to do with workshops. People come to workshops when they can and when they want to. Sometimes to fix stuff, sometimes to learn, sometimes (more often than not) to do both!! My knowledge of vintage tech was very limited when I started with VCF, especially because it relied on my memory from stuff I did 30-40 years earlier! (Not the most reliable for sure!) As time has passed I’ve learned tons, but my focus is still very limited compared to many others. My background is a user and I have no experience in electrical, programming, engineering, etc. What I know now (still extremely limited) has been from getting involved in workshops and learning on my own as well. Best advice I can give you is to be more proactive and seek out involvement instead of waiting to be asked. That, and perhaps reach out to those that organize the various events (workshops, warehouse work, etc) directly as opposed to a generic airing of perceived grievances on the main list.

Laura, I'm a good example of timing. I have kids and and a challenging work schedule, and summer is especially rough for me and I basically become a ghost until at least September, to the point where the only time I hear anything is when I read the mailing list. When I have bandwidth, I offer to show up, but sometimes the type of work that needs doing is not in my wheelhouse and I'm declined. Otherwise, I come to workshops when I can. No need to say goodbye.

Laura, I think you might have misunderstood, sometimes when we ask for volunteers we are very specific on timing and that just may not have worked out for you in the past. VCF is very open to anyone, regardless of gender, orientation or choice of pet being a part of our community, this includes workshops, shows, volunteer work or participating in our online communities. Heck, we even let Evan be a part of the group and he's a cat person, so that shows you we accept anyone.

In the specific instance of a PET, I happen to like the crispness of the original mono CRT (no shadow mask, no color bleed). If I could find 9" mono LCDs, that would be great but it's just not something anyone bothers to make. There used to be mono LCDs for laptops (and I have some) but it would take a custom adapter to drive those from the signals from a PET (video + H sync/V sync) or a composite conversion of it. -ethan

Pet with 9" screen
by David Hoelzer 19 Aug '19

19 Aug '19

I've been slowly working my way through rebuilding the CRT board for a 9" 2001-32 PET. As I've been working, I've been discovering that the components on the board don't all match the specs in the documentation, but that's ok... Eventually I'll get together all of the pieces I'm missing and reassemble everything.. I'm working right now to figure out why the schematics call for a mylar capacitor but my board had a differently rated electrolytic. Anyway... I'm seriously thinking about taking a 9" LCD panel with a composite input and wiring up a composite converter circuit to the internal video connector on the board. I would dismount the CRT tube and put the LCD in in its place. Of course, I'll preserve the removed parts for posterity... but does this offend your sense of vintage stuff? Personally, it seems practical to me since I'd like to do some things with the PET... and the CRT is a potential major source of problems in addition to an energy hog/heat source.

Anyone interested in some AUI to RJ45 transceivers?
by Bob Applegate 19 Aug '19

I uncovered four AUI to RJ45 transceivers in the basement. I think the AUI to Thinnet transceivers are gone, but is anyone interested in these? I used them on some DEC workstations in the mid 1990s. Email me off list if interested. Bob

Ouch. I’m only a dude that shows up for VCF East, but I hope the club isn’t making anyone that would like to participate not feel welcome. > On Aug 19, 2019, at 11:59 AM, laurakid via vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> wrote: > > > From: laurakid <laurakid7(a)yahoo.com> > Subject: Re: [vcf-midatlantic] Welcome newbs! > Date: August 19, 2019 at 11:59:22 AM EDT > To: vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> > > > thinking i really really don’t belong here. i liked volunteering and learning but seems since there is another girl coming to things, I have been sorta cast aside.
