Testing 4164/41256 RAM Chips
by Herb Johnson 15 Sep '17

15 Sep '17

Responding to various suggestions for old DIP-chip RAM testing. cheap EPROM programmers that test things like TTL or RAM, are not likely to be better than go / nogo. THey won't test at anything like access speed. Commercial grade RAM testers are likely better, but few have those. Vintage computer designs for DRAM were not always very good, and many of them aged poorly. (Changes to the other components make the DRAMs work marginally.) What chips may work in one brand/model, may not work in another. And frankly, prices for old 16K and 64K and 256K chips (IBM PC class) are fairly cheap - buying them is simpler than extracting and testing. Now, if someone needs an exact brand/model/datecode of DRAM chip, then more effort is warranted. Otherwise, there's not much incentive to work hard to test these chips. One puts them in the application hardware and runs such tests as they can. Some of these old circuits not only need component repairs, they need in-field circuit changes. This is hard work that few do. Also: specific brand model owners probably have known-fixes and specific suggestions about DRAM selection. But for some vintage systems, one can choose static RAM and have better luck than with DRAM. Herb -- Herbert R. Johnson, New Jersey in the USA http://www.retrotechnology.com OR .net

Testing 4164/41256 RAM Chips
by John Heritage 15 Sep '17

15 Sep '17

Hey folks, I've come across an old PC XT motherboard that's sat in a dirty warehouse for a long time. It has 18 x 41256 and 18 x 4164 (640KB total + parity) RAM chips. Knowing that i've needed some of these in the past to repair my old Atari computers, I'd like to test these individual RAM chips somehow, but preferably without abusing the old sockets on my Atari's.. Does anyone know of a relatively simple circuit I can build to test these chips directly? The 4164s come on the Atari 600XL, 800XL, 1200XL and 130XE, and the 41256 come on the 4-chip versions of the 130XE. The micron 4164's that came on a lot of old Atari's are just flat out dying (I had 3 x 800XLs out of 7 that had bad ram), so these are handy for that or other communities. Thanks! John

Re: [vcf-midatlantic] Oracle finally kills off Sun
by Jeffrey Jonas 14 Sep '17

14 Sep '17

I consulted to clients who were all-Sun, even in y2k. One was ISO 9001 certified for their software process so I guess running Solaris on Sun hardware was part of that. They liked using 2 Sun 1000 servers with the serial ports criss-crossed so one machine could access the other's serial console and reboot it, dropping to firmware mode if required. None of this switched outlets of remote reset-switches. I'm frustrated with the way Sun never fulfilled their potential. The SunRay "thin client" terminals could have beaten the pants off of today's room of Windows machines had the servers been properly maintained with the latest software. Too many web pages simply didn't work on the Sun terminals. And security was much better with the built in SmartCard reader. -- Jeff Jonas

Museum report / Atari Party
by Evan Koblentz 14 Sep '17

14 Sep '17

Mixed bag today. Infoage hosted an NJIT alumni event around lunchtime, so we had many visitors from 1-3ish. Then it was dead. I closed early around 4 and went to Bill Lange's "Atari Party" at his home in central NJ. Couple of dozen people there enjoying videogames and food/drink. Glad to see many friends: Bill and his wife Lucy, Pete F., Amiga Bill W., and others who'd been to VCF East or who knew of us.

OT: Hurricane Harvey Relief
by Joseph Oprysko 14 Sep '17

14 Sep '17

To my friends in the VCF; My brother Jim who lives in Lumberton, TX and had everything he owned washed away and destroyed. His house was submerged under the flood waters for 4 days. He just got back to his property today. His home will need to be demolished and rebuilt from the ground up. He is literally rebuilding his life from scratch. He's a long time computer user and lost everything, including the loss of a number of vintage systems as well. I'm reaching out to my friends and compatriots, in hopes we can help him some. My sister and I setup a gofundme account to at least be able to help him with some of the necessities. While his vintage systems are probably the furthest from his mind right now, I'm hoping that we can come together and help someone in need. The most immediate needs are support so he's able to get food and medicine for himself, his wife, and his fur babies. (His pets). His house was covered by 119" for almost 4 days. (Yes, almost ten feet of water.) There is little, if anything salvageable. If you're able to help, please do. https://www.gofundme.com/household-recovery-fund Thank you, Joseph Oprysko -- Normal Person: Hey, it seems that you know a lot. Geek: To be honest, it's due to all the surfing I do. Normal Person: So you go surfing? Normal Person: But I don't think that has anything to do with knowing a lot... Geek: I think that's wrong on a fundamental level. Normal Person: Huh? Huh? What?

[OT] DC-Area Workshop - September 16th and 17th - Middletown, MD
by J. Alexander Jacocks 14 Sep '17

14 Sep '17

All, Since VCF can't do a workshop, due to facilities usage conflicts, this fall, I'd like to offer to host a smaller workshop, at my house, in Middletown, MD. I have a 3-car detached garage of about 960ft^2 that we can use for the purpose. There is air conditioning, and a refrigerator, for drinks. I have plenty of power, and some table space. Please bring yourselves, your projects, folding chairs, folding tables (if you have them), and anything else that you might want. We will provide some drinks (but feel free to bring your favorite), and are willing to order lunch, based on the requests of the attendees. We have very limited space in the house, but talk to me, if you want to stay the night. There are hotels not so very far away. Date: September 16th and 17th, 2017 Time: Starting 10:00am Saturday, ending Sunday around 5:00pm Place: Alex's house, Middletown, MD Please RSVP, so that I know who is coming, and when. I'll provide directions directly to the attendees. I asked Evan, before posting this, to make sure that this wasn't going to conflict with VCF needs, as this is definitely NOT an official VCF event. Hope to see you here! - Alex

Maker Faire -- helpers?
by Evan Koblentz 13 Sep '17

13 Sep '17

Jeff B., Dean/Drew (part of the time), Mouse, and I are staffing the VCF table at World Maker Faire on September 23-24 in the NY Hall of Science (Queens). We won Make Magazine Editor's Choice awards there in 2014 and 2016. :) This year we're making a BASIC learning lab. We are setting up four computers (Apple //c, for convenience) and we'll guide kids through a script every 30 minutes in a formal presentation. We even bought a small amplifier and wireless microphone (thanks Jeff B. for doing the research). It'll be pretty cool. We could use more helpers. People who are extroverts, good teachers, good with kids, will represent us professionally, and are reliable. In exchange you get a free full-weekend Maker Faire ticket. Email me off-list if you're interested. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
