Workshop day 2
by Evan Koblentz 09 May '17

09 May '17

Today's workshop attendees were me, Jeff B., Bill Dromgoole, Bill I., Dean/Drew, Adam, and Tony. Bill and Bill continued working on Univac + EAI TR-20 projects respectively. Dean/Drew worked on a TRS-80. Adam tested one of his Amigas. Several of us (me, Dean, Drew, Adam) worked on museum-owned Amigas. We got a 500 working and then a 1000 working, both with workbench disks previously provided by Anthony/Bill of Guru Meditation renown. The 500 is in our museum temporarily. The 1000 will replace it when we get a suitably new-yellowed keyboard. Dean took home one of our keyboards and will try to retrobrite it. We along with Tony (and Google!) tested the museum's NeXT Station. It works pretty well. We'll display it soon as the next "artifact of the month".

Just purchased a Solid State Music IO-8, apparently the manual is not available online, and isn't listed in Herb's documentation collection. Anyone have it? Looks like it's eight Intel 8251A serial ports. Thanks, Jonathan

FS: IBM 5160 PC/XT 64-256K Motherboard, Upgraded to 640K
by Systems Glitch 07 May '17

07 May '17

link: http://www.ebay.com/itm/272662031085 This board had a dead 8088 CPU, which was replaced with a similar ceramic AMD D8088 CPU. It has, at some point in the past, been modified to support 640K RAM (a common mod for 256K boards) -- this can be reversed by removing an IC and a jumper. Fully tested as stated in the listing Fully assembled and tested XT-IDE rev 3 boards are available for bundled purchase with this board -- your XT-IDE will be tested in this exact board. Thanks, Jonathan

[cross posted] I was able to find time to edit and post speaker videos from this year's Vintage Computer Festival Southeast held last weekend in Atlanta. Amazingly I did it within one week and not a year or more! Here is the speaker summary and bios from the VCFed website: http://vcfed.org/wp/festivals/otherevents/vintage-computer-festival-southea… [1] And you can find the videos on the AHCS Vimeo channel: https://vimeo.com/user50868990 [2] Don French discusses the genesis of the TRS-80 Model I at Tandy/Radio Shack: https://vimeo.com/216109117 [3] Andy Hertzfeld from Apple talks Apple II and his journey to Cupertino: https://vimeo.com/216104204 [4] Zach Weddington hosts a special screening of his Viva Amiga documentary film followed by a panel discussion moderated by Adam Spring: https://vimeo.com/216081365 [5] Chuck Peddle via Skype discusses the history of the personal computer and his current projects: https://vimeo.com/216072422 [6] I've also continued to work on the 4.0 backlog. I've added David Larsen's discussion on the Bug Book series and his computer museum here: https://vimeo.com/216398748 [7] And as-posted from last year, Bil Herd discusses his early Commodore days: https://vimeo.com/161861581 [8] I still have Ray Holt, Jerry Mannock, Mary Hopper, and podcast videos from 4.0 in my work queue. 3.0, 2.0 and 1.0 to come (Jason Scott, Robert Uiterwyk, Jonathan Zufi, Carl Helmers, Robert Tinney, Dick Huston, Dan Kottke, and others). But no ETA on finishing as of yet, sorry. There are some flaws in video (Andy's lectern mic - doh!) and audio (damn kids!), but they turned out ok. They are all open to free download. But please give proper attribution when sharing. On behalf of the entire Atlanta Historical Computing Society who work hard every year to make this happen, thanks and enjoy! We do this stuff for you guys!

DRAM memory testing - AboveBoard AT
by Richard Cini 07 May '17

07 May '17

All – I have an Intel AboveBoard/AT that looks like it works (it backfills RAM to 640k), so I bought a bunch of extra 256kbit (41256-120) chips from Jameco and boost the memory a bit. My plan is to use this AT for diskette imaging – I bought an Adaptec Floppy-SCSI controller (AHA-1522) which is the most flexible for use with ImageDisk. I know that these boards are somewhat finicky with the address settings, but when I try to set the board memory limits and run the diagnostics it complains about at least one bad chip but doesn’t identify the row or column. Arrrgh. Too many chips to swap one at a time, then reboot and retest. Does anyone have a DRAM tester that they can loan me so I can test all of the chips at once? Also, if anyone has experience configuring this board, I’d appreciate hearing from you. The instructions I found seem simple, but I’m trying to knock off possible problems one-by-one. Thanks!
