by Ryan Burke 09 Apr '26

09 Apr '26

The Computer Museum at System Source is hosting a swap meet and warehouse sale on May 2nd and 3rd in Hunt Valley, Maryland. During this event, we will have the warehouse open for people to purchase some of our duplicate artifacts, and help us clear some space. The swap meet will begin at 8:00 AM on May 2nd and vendors may come at 7:00 AM to set up. The swap meet ends at 1:00 PM and food will be sold on site. The workshop will be from the end of the swap meet until 9:00 on Saturday and from 9:00 AM until 5:00 PM on Sunday. If there is a rain delay, we will make an announcement 48 hours before the start of the event. After the swap meet, there will be a regular computer workshop in the museum.

Anyone have an Atari STacy I could borrow at VCF?
by Ethan O'Toole 08 Apr '26

08 Apr '26

Heya! I pulled out my STacy, and I am getting stuck in this issue where the power supply cycles. Something is shorting and dragging down the PSU. I am not seeing a dead short tho, it happens after it comes up. I had recapped the power supply board when I got the machine -- and it was working. Mostly. I've had some strange issues. It's an annoying design where the machine gets 17vdc center pin positive which hits a sub pcb that is a switchmode supply generating 5/12v and running the inverter for LCD backlight. It's connected via pin headers and humps the main board -- so it's not possible to easily run the power supply without the main board until I build a test harness. I just got done recapping main board hoping one of the electrolytics was going to short after power on but still getting same issues. I plan to continue to troubleshoot it, but as a backup plan does anyone have one I could use for my display @ VCF if mine continues to not cooperate? I plan to run Notator or Cubase on it with midi synths and stuff.

Apple TimeMaster
by Hopkins, Justin 08 Apr '26

08 Apr '26

Restarting this thread without the Digest stuff clogging it up. I know next to nothing about these, but it appears they did not come with drivers, but instead came with an on-board ROM and the install procedure is to flip Dip switch 1 to the on position to initialize the card on the first boot, then flip it off to use. Is this the one you have? https://wiki.preterhuman.net/Applied_Engineering_Timemaster_II the HO has 4 DIP switches, but this one has 8.

Tony, that sure looked like it, unfortunately it doesnt have any time setting utilities, and likewise it doesnt detect the card ;-( Jeff > On Apr 7, 2026, at 8:00 PM, vcf-midatlantic-request(a)lists.vcfed.org wrote: > > Send vcf-midatlantic mailing list submissions to > vcf-midatlantic(a)lists.vcfed.org > > To subscribe or unsubscribe via email, send a message with subject or > body 'help' to > vcf-midatlantic-request(a)lists.vcfed.org > > You can reach the person managing the list at > vcf-midatlantic-owner(a)lists.vcfed.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of vcf-midatlantic digest..." > > Today's Topics: > > 1.

Apple II - TimeMaster (1?) Card
by Jeff G 07 Apr '26

07 Apr '26

So I'm trying hard to get some of my crap working for VCF and silly me picked up an Applied Engineering TimeMaster clock card for my Apple II, really because a piece of software I'm hopefully showing off used it (and I found the orig manual to it, which may or may not be available online). That said, I have no software, and now realizing that, well, I can't set the time on the thing. I may be able to dump the rom and find a way to set it manually I guess via pokes somehow, but I'm not an Apple II expert at all (although having fun with it). Does anyone happen to have the software to this? Note that this is NOT the "H.O" card; I tried the software for that, and naturally it doesn't work as it tries to detect the card. Jeff

Revision 2026 Demos
by Ethan O'Toole 06 Apr '26

06 Apr '26

Lots of neat demos at the revision competition over the weekend. I caught a bit of the livestream near the end. A few good Amiga demos that target A500 512kb + 512kb OCS, no accelerators. Razor 1911 stole the PC demo competition with this: https://www.youtube.com/watch?v=dybkLM-1eQo Killer throwback PC demo dialup days and all that. It looks better running on a real PC (Windows 10/11, doesn't work with Intel integreated you need a GPU I think? Also windows says it's a virus you need to whitelist it.) The compression of the youtube video looses that some of the pixels are ascii art at really hi res and stuff. Also they chopped it at the end, it's got a lot of scroll on the real one but they cut it on the livestream. There was some other good PC demos and a lot of stuff showing up in random languages and strange hardware.
