“Comcast@Home” internet speeds 1998 or so?
by John Heritage 03 Feb '22

03 Feb '22

Hey folks, I’m trying to remember what download speeds Comcast@Home offered circa 1998 (when I first had cable modem). I remember the upload speeds initially being 256-384 kbps but then Comcast cut the upload to 128 kbps. This was terrible not just because it was slow but it was barely enough bandwidth to even request data fast enough to saturate the download speed. I think the initial download speeds were 3 or 4 mbps with cable modems in 1998 (south jersey area - former Storer Cable area), but I have a couple of friends who think it was more like 768kbps - 1 mbps. Any one have memories of this time? P.S. My google-fu sees a lot of ~ 2.8 mbps down on Cox@Home and some other @Home providers around 2000-2003 but I’m having trouble finding earlier than that period online. Thanks! John

https://www.tvtechnology.com/news/comcast-announces-10g-advances <https://www.tvtechnology.com/news/comcast-announces-10g-advances> Full Duplex DOCSIS4 changes things. As for 'not enough bandwidth (in coax)' - you have to understand what is happening. The entire path from the head-end to your home drop is being virtualized. “To do this, the team activated what we believe to be another world first – a virtualized cable modem termination system (vCMTS) powered by Full Duplex DOCSIS 4.0 Technology." The virtualization of the CMTS plant infra is going to allow these speeds (for customers that choose and pay for that tier). Yes, it's going to cost, and maybe you are good with 1Gb! But some people will want more. 10G is just showing the max bandwidth - I doubt there will be a plan for 10Gb available for a while.

"Ideas That Created the Future collects forty-six classic papers in computer science that map the evolution of the field." So far it's fascinating to read the actual documents that defined where we are now. To see all 46 of the papers included, this link has them listed: https://dl.acm.org/doi/10.1145/3471469.3471473 <https://dl.acm.org/doi/10.1145/3471469.3471473> Looks like IEEE members can download a PDF: https://ieeexplore.ieee.org/document/9357635 <https://ieeexplore.ieee.org/document/9357635> I like having this in paper form FWIW. -andy

It is probably rate limited 10G or what they call fractional. I have multiple 10Gbps circuits at work and we were offered fractional. They all seem to do the same thing. They run some SMF and put a box on your site that they manage to do the rate limiting.

by Mike Willegal 02 Feb '22

For DOCSIS 1.0, max upstream bitrate was either 5 or 10 Mbps, depending upon whether the physical plant could support 16QAM or required usage of slower QPSK modulation. Actual per modem maximum was significantly less because of the way upstream bandwidth was managed through a TDM scheme that required the cable modem to request upstream bandwidth every time it needed to send something. If I recall correctly most cable plants started out having a lot of trouble with QAM 16, so ended up at QPSK speeds to start with. Downstream theoretical max per modem was a bit under 40 Mbps, a bit higher in Europe because cable channels are 8Mhz wide instead of 6Mhz. Actual per modem rates would typically be significantly less. I can’t remember whether per CM rate limiting was provisionable by the MSO (cable operator) in the very first versions or not, but it wasn’t long before MSO had pretty good control of who could use what bandwidth. Regards, Mike Willegal things have changed a lot- a few years ago I was able to demonstrate about 2Gbps upstream in a lab environment to a single modem with DOCSIS 3.1 technology

Wrap-up of System Source Repair Workshop 1/29 & 1/30, 2022
by Jeffrey Brace 01 Feb '22

01 Feb '22

I had a great time at System Source's Repair Workshop this past weekend. Bob Roswell was a very generous and gracious host. I left at 7:30PM on Friday night because the snow was piling up in NJ. I live near InfoAge so the whole area got 12 inches of snow. But west and southwest of my home, got little to none. So the drive to System Source was a breeze with mostly highway. It took about 3 hours. Stayed at a hotel Friday and Saturday night and got a good sleep. When I got there Saturday things were in full swing with the usual suspects from InfoAge repair workshops, plus the usual System Source suspects. So a very good turnout of about 25 or so people. Lots of stuff fixed as I saw. I made some pickups of repaired VCF artifacts and drop-offs to be repaired artifacts. I loved looking at what was new and looking in more detail at the exhibits in the museum. I also got to catch up on all my friends there and talk about vintage computer stuff it was great! I also got a chance to play with the Xerox Alto for a few hours and see what worked and what didn't. Very cool and rare opportunity for a rare machine that works! This was my favorite part of the weekend. Maybe others want to chime in on what they were working on. ========================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey(a)vcfed.org

Re: [vcf-midatlantic] OT: time to downsize
by Bob Shuster 01 Feb '22

01 Feb '22

Just an update and a question. UPDATE: I'm slowly going through my newer (post-1984) Apple products and testing and/or clearing the hard drives of personal information, then photographing and adding them to my Google Sheets doc. I suspect the older machines will go faster as they have no hard storage to contend with (or obscure monitor connections that I have to remember how to connect or locate the right adapter!) Be patient, the list will be posted as soon as I make enough significant headway. QUESTION: I’m just starting to tackle my Macintosh Plus (ED) 1MB (M0001A), but I cannot locate system disks to test it. Would any group members have these and be willing to give/loan/sell me so I can test the machine? Bob Shuster

OT: PC donations to Red Bank Regional High School (Little Silver, NJ)
by Adam Michlin 31 Jan '22

31 Jan '22

Hi Everyone, As many of you know, I teach computer science at Red Bank Regional High School in Little Silver, NJ. I'm trying to help my colleague who teaches IT. He does a lot of projects where the students take apart computers and put them back together (a project near and dear to mine and many of your hearts), but his class sizes are outpacing his supply of PCs. I'm hoping to collect 10-15 not so vintage PCs (core 2 duos and P4s are fine, but obviously we won't complain about better machines). The key is they have to be normal sized PCs, the kind that make it relatively easy for a 9th or 10th grader student to take it apart and put it back together. So no small form factor PCs or laptops. These would be donations and individual machines are fine. If you happen to be downsizing your desktop PCs at the office, that would be even better. Working or not working. I can pick up in most of NJ and will be at the VCF Swap Meet at InfoAge on February 26th, as well. Please contact me directly off list at <adam.michlin(a)vcfed.org> if you have any offers or questions. Thank you for your consideration, -Adam

Vax 9000 transfer
by Jeffrey Brace 31 Jan '22

31 Jan '22

Hello everyone, The VCF Board and Steering Committee have decided to transfer our VAX 9000 out of our inventory to someone who has the ability to move 18 pallets and 6 rolling cabinets without charging us to get it out of the warehouse. We don't have the funding for such a move. This decision was made primarily because the machine is not functional, and we don't have the resources (time, parts, power requirements) to make it operational or display in our museum. Please be assured that it went to a very good home, to someone who has the time, space, and money to display it properly. In addition to providing a better home for this historical artifact, this move provided us the added bonus of clearing a significant amount of space in our warehouse, which gives us much needed breathing room to better organize our existing artifacts, as well as be more prepared for any potential future rescues. The triage process for computer rescues is never ending, so we need to manage all of our resources to keep things under control, as well as acknowledge when a particular artifact might have a better home elsewhere. ========================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey(a)vcfed.org <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

by Dave Shevett 31 Jan '22

31 Jan '22

Hi everyone, new to the list - I'm hoping to make it to the swap meet on Feb 26th, and I'm wondering if folks have a few things I'm looking for... * AT&T 3b1 / 7300 / UnixPC hardware - looking for an actual 3b1, but also for boards and media. * AT&T 605 terminal(s) * Nothern Telecom Displayphone (hah, unlikely, but I want to toss it out there) * DEC terminals - specifically any VT2x+ terminals (Have several VT100's already) * DEC micro- hardware. Talking microvax, micropdp11, and Pro350 - specifically the 'under desk vertical cased' machines * DEC VK100 / GIGI terminal (a barco monitor with it would be amazing) More traditionally * TRS-80 Model III and Model 1 hardware * Non-bulky ascii terminals (altos terminals would be wonderful) And, because I'm the Handheld guy, any handheld computers. My wishlist / current collection is here: https://planet-geek.com/vintage-handheld-computers/ I have to offer: * Osbourne 1 * Kaypro 2, Kaypro 4, maybe a Kaypro 10? * Several HP calculators * Coleco Adam complete Looking forward to seeing folks... -d -- Dave Shevett shevett(a)pobox.com

So the usual suspects from both CDL and VCF have been upgrading the network at Camp Evans. As noted by Jeff B, we extended single-mode fiber to 9032 and have the access points and a 48 port PoE switch staged to deploy. Question for the folks that will be exhibiting in or using 9032A for VCF East: Will anyone need telephone lines (analog / ISDN) or wired Internet connections during VCF East in the big room?

Plaintext Emails

All, Hate to be That Guy on a listserv, but some folks are sending non-plaintext emails, which the listserv turns into an attachment (I get a body of "Empty Message" with something like email-1.eml attached). I don't bother to read those, and I suspect few who read text-only mailing lists do either. You can typically configure an email client, even most webmail clients, to treat listservs as plaintext-only. Please consider taking the time to do that for those of us who will otherwise just ignore the message. I also don't know what it looks like on whatever the web presentation of the list is.

Another T-Shirt Rescue (DEC Alpha)
by Adam Michlin 29 Jan '22

Hi Everyone, After leaving Amdahl, my father went to a couple of other companies including Synopsys, Cadence, and Transitive Technologies (which made the original dynamic binary translation software for Apple's PowerPC to x86, aka Rosetta, a story for another time). Some time in there, he gave me a tshirt he got from who knows where that DEC was using to promote the then new Alpha chip. I was so excited because I had just read about the Alpha in Byte magazine and was in the middle of the study of computer architecture and knew this was going to be the next great thing (oh well). I've been wearing it up until about a year ago when it had all but become tatters. I never did get to play with an Alpha machine, but so it goes... Dean Notarnicola was nice enough to scan it and Javier Rivera cleaned it up for reprinting. Neither Dean, myself, or I (or VCF) receives any money from the sale and yeah, we know DEC (now owned, I believe, by HP) might copyright strike us so get it while you can. https://www.8bittees.com/product/alpha-two-sided-tee/ Best wishes, -Adam

OT : I need help.

My health has declined and I had to sell my home. I am in long-term nursing care. My family needs help finding homes for my large number of computers and other technological items. There is too much for me to list here. Can someone contact me off-line if VCF can help me with this. I'd like to sell as much as possible for a decent price to avoid having it go into a landfill. Thanks! Al Hartman

OT: time to downsize
by Herb Johnson 26 Jan '22

Bob Shuster: > So - I’m not sure how to start with this. Does the group have a For Sale page where I can post photos, etc.? I’ll need to dig out each of the systems (carefully stored in my heated/cooled workshop) and test and figure out prices, but I will definitely entertain offers. For specific inquiries please email me, but for discussion of how to go about reducing my collection [and assuming the admins agree that it’s on-topic] that can be on-list. > in general anything else will need to be picked up [at a PA location] I think Bob has a reasonable question; nobody replied exactly to it so far. I read "does the VCF-Midatlantic group have a for-sale Web resource for private, on-site, local-only sales?" Not shipping to, not bring-to-sell-at, as some responded. As Bob replied, it's just impractical for some of us, in some cases, to ship. Or to bring volumes of materials to an event, or even to attend an event. I think it's fair to say, it's "unwieldy" to post at length here, or repeatedly, about numerous items one wants to sell. Bob asked for discussion, asked for "the admins". Maybe, some resource could be offered and supported, like the vcfed.org national/international for-sale forum, but "local" to central New Jersey? Maybe, something like that "want to buy/sell Google spreadsheet" for the VCFed-Mid swap meets, but more permanent, maintained? As I wrote a reply, Jeff already offered to make Bob a Google Drive folder. That would also be a good for-local-sale general resource, as long as sold items are culled out.

Recovery of RD53 image data
by Jeffrey Brace 26 Jan '22

26 Jan '22

Someone in northern Maryland near the PA state border is looking for the following: He has a DEC PDP-11/73 with a non-functional RD53 hard drive, and several RSX-11M installation and backup tapes on TK50 tape cartridges. He would like to migrate the RD53 image to modern media so that he can (initially) utilize it via simh, and (eventually) use it in his 11/73 via a hardware drive simulator. Failing recovery of the RD53 data, He'd like to migrate the data from one of the TK50 tapes to modern media. Anyone ready, willing and able to do this? ========================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey(a)vcfed.org

FREE: Dell Precision 690 Workstations @ System Source Workshop
by Jonathan Chapman 26 Jan '22

26 Jan '22

All, We've got four Dell Precision 690 workstations we'd like to offload. No desire to deal with shipping them. I'll be at the System Source workshop and can bring them up. We have not tested these, but they look good and came out of an engineering workgroup. They don't appear to have cap problems. Hard disks pulled. Thanks, Jonathan

OT - incandescent bulbs
by John Heritage 26 Jan '22

26 Jan '22

Just curious - I bought a (new to me) home and I am finding and replacing old Edison bulbs :). 200w and smaller incandescents. Does anybody here want the old bulbs ? I know some people prefer the light so just figure I'd ask.

Just an update, at Jeff’s (and others) suggestions, I am putting together a Google Sheets list with asking prices, descriptions, and links to photos. I will post this to this list when I get a little further along. It’s both fun and challenging to go through my systems one by one and trying to remember how to connect displays and such, even if it's for the last time. So please be patient! Also, make sure if you want to inquire about a purchase to send to me directly and not to the list, please? Not only does it clog up the list (sorry!) but I only get the digest version so I won’t see your message until the next morning. Bob Shuster

> FWIW on the tape baker, Chuck Guzis always used to recommend a 25W bulb in a cardboard box for a few days. Should be easy enough if you have any old 25W bulbs still kicking around. - Dave Riley Home Depot offers 15W and 25W incandescent bulbs. The heat produced may depend on the size of the box. Dave Riley, do you recall details? Maybe a temperature set-point? I think I could design a relay and a 555 as a controller. But for warm environments, people use things like rice-cookers, crock-pots, dish warmers; thrift store items. My wife dyes fabrics overnight in a bowl, inside a covered container with a layer of water, on a dish-warmer. A stable, but wet, environment. Pebbles could provide dry thermal mass, seems to me. - regards Herb -- Herbert R.

OT: time to downsize
by Bob Shuster 25 Jan '22

25 Jan '22

Well, folks, I’ve gotten to the age where I need to seriously downsize my hobbies and collections, not wanting to leave it to my children to have to deal with in later years. (I had to do that recently for a relative.) On the electronics side, I’ve decided to concentrate on my vintage video game systems - and therefore sell off most of my vintage computer stuff. My collection includes mostly 8-bit stuff: TRS-80 Models I, IV, M100, etc. - Atari 400, 800, Stacy, Portfolio, ST, etc. - C64/VIC20 - T/S1000 (including an unbuilt kit), Apple II, II+, IIe, IIe Platinum, IIgs - Wang WLTC - Mattel Aquarius - TI-99/4A - many others that I still have to dig out - plus lots of peripherals, disks, manuals, etc. Also have some newer Macs starting with a Mac Plus in an Apple carrying bag. I’m starting with you guys before trying to list elsewhere, although I may hit some of the dedicated FaceBorg pages (such as for Aquarius and Apple II.) I may be willing to ship some of the software, but in general anything else will need to be picked up here (near the Fort Washington exit of the PA Turnpike) or nearby, and cash or PayPal for payment. I may also consider trades for some of the video game stuff I’m looking for. So - I’m not sure how to start with this. Does the group have a For Sale page where I can post photos, etc.? I’ll need to dig out each of the systems (carefully stored in my heated/cooled workshop) and test and figure out prices, but I will definitely entertain offers. For specific inquiries please email me, but for discussion of how to go about reducing my collection [and assuming the admins agree that it’s on-topic] that can be on-list. It pains me to do this, but the clutter is getting out of hand, and I haven’t touched most of these in years. It’s time for someone else to enjoy. Bob Shuster
