Ohio Scientific Universal RAM Board GW-OSI-RAM1
by Systems Glitch 03 May '17

03 May '17

Finished building a prototype mezzanine board and testing with the IM6100 (PDP-8 on a chip) in the 560Z board today. Full writeup: http://www.glitchwrks.com/2017/05/03/gw-osi-ram1-universal-ram There are a couple of tweaks required, but I should be doing a first production run of boards before long. This board is: * 128 KW, 12-bits * Optional memory management/bank switching * No hard-to-find/expensive ICs (8T26, et c.) * All through hole * Includes lamp register mezzanine header * Largeish prototype area The lamp register is on a mezzanine for a few reasons. First off, octal vs. hex grouping! It really throws me off to try and interpret one on the other. Second, it allows remote mounting on a ribbon cable, i.e. board can be mounted to a front panel. Third, I'll likely design a 7-segment version. Thanks, Jonathan

VCF-SE
by Evan Koblentz 02 May '17

02 May '17

I'm finally rested up from VCF Southeast. Had a great time! Arrived on Friday morning, immediately found Bill Degnan and tons of other friends -- all the SE crew who attend VCF East; along with Mike Lee, Jack Rubin, David Larsen, Jim Brain, Malcolm M., and lots of others who've been to East and/or are friends from other parts of the hobby (online, West, etc.) Sat next to Tandy's Don French at dinner Friday night. That was a special treat. Bill and I had our tables next to each other as the combined VCFed booth. We hung the Fed banner behind us in the center. Bill showed a DEC Rainbow alternately playing chess and connected to the VCForum IRC. I showed the Lego robot. It behaved pretty well all weekend. The Laser 128 worked flawlessly. Chris Eckert, son of ENIAC co-creator J. Presper Eckert, joined some of us for dinner Saturday night. Turns out he lives four miles from the venue. Didn't know that until I arrived. His wife read about the event in some local paper and he told her, "That sounds familiar, let me check with Evan" ... small world. As always, these weekends are over too fast. I was glad to be at a VCF and not have all the responsibility of being in charge. :) David Greelish donated an IMSAI pillow for our museum. It's a blue rectangular pillow with one long end that looks like a front panel. Pretty cool. I'm grateful for the person who gave me the opportunity to attend and for all of the SE crew's hospitality the whole weekend long. ________________________________ 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

What's this about a workshop?
by Jeffrey Brace 02 May '17

02 May '17

I recall someone posting about some workshop coming up. That sounds like a great idea. I have a bunch of Commodore 64 that I need to fix. I sure hope that there are people can help me fix them. Does anyone have the details about it? -- Jeff Brace - ark72axow(a)gmail.com Sent from my Commodore 64 ========================================================

Museum Report - Sunday 30Apr2017
by Todd George 02 May '17

02 May '17

A day late... Anyway, I was docent yesterday. Chris Fala was there with me as we wanted to pick up the shelving that we used for the Commodore exhibit at VCF East. Glad Chris was with me, it was quite a busy day. We had two older couples that came through together, the one husband was extremely knowledgeable and very interested, said they had visited us before but not in the new museum space. We had a mother and son touring the InfoAge facility, and I gave her directions a few times to other exhibits around InfoAge, eventually they walked through our exhibit. The mom had more interest in computers than she had initially let on. A gentleman named Nick stopped in to test out a handful of 3.5" disks he had on our IBM PS/2. He hung out for a few hours. Bill Dudley stopped by to drop off a PC. We had a scout troop of probably 6 along with 3 or 4 leaders, very little attention span left as it was late in the day. I want to say I'm missing a few parties as well. The groups were nicely spread out throughout the day, kept it moving. I think that's it for the report. I hope I didn't miss too much. :) See ya! -Todd

PC needed for VCFed BBS
by Evan Koblentz 01 May '17

01 May '17

Hey everyone, As announced a couple of weeks ago: we need a PC for the VCFed BBS. Some requirements: - It should be a PC that's already fully working, we don't want to get some junk and have to fix it up. - It should NOT be a tower: we prefer a mini- or micro-ATX - All it will ever run is one or two DOS programs. In fact, you'll save us time/effort if you pre-install MS-DOS 6.22 on it. - Mobo should be maxed-out with the most memory that 6.22 can handle. - The more quiet and energy-efficient, the better. - SSD > HDD - We'll attach a traditional dial-up modem or two, so it should have (serial?) ports for this. (Big ol' telephony card not wanted.) Who can donate something to meet these requirements?

88-DSK RAM?
by David Hoelzer 01 May '17

01 May '17

Does anyone happen to have a Briel 88-DSK RAM kit that they aren’t using? I finally got around to repairing my 8800 clone and realized that I never bought the DSK, and I think Vince is out of business.

Festivus 2017

I know that this is really early, but I like to reserve the space and then forget about it until later. Since World of Commodore is December 2/3, I was thinking that either December 9/10 or 16/17 weekend would be best. What say youze? -- Jeff Brace - ark72axow(a)gmail.com Sent from my Commodore 64 ========================================================
