I use them both a lot on all of the unibody Macs that I'm fixing. Details on what parts drive what in ways that are fairly simple to understand (I just need the guidance as to what part to replace as well... not an EE... I can solder well enough for any sort of repair on these :-) ) I've also got some things for stuck drives (and sources for the gear that can go as well). Earl

How about August 20/21? This spaces it out from the last event. August 27/28 are not available.

July Workshop Date will be July 16/17

The July workshop will be July 16/17. I realize this is one week before HOPE, but I want one more weekend to work on the Commodore 64 robot in case I don't get it working at the June workshop. July 9/10, 23/24, 30/31 were unavailable. I don't think anyone would want to do July 2/3 because it is a holiday weekend.

Took 11 years but someone is finally giving us a black BH Apple. That's all I know for now.

Running Windows 1.04 in emulation
by Richard Cini 28 Apr '16

28 Apr '16

All — I’m progressing well with the Windows 1.04 SDK -- I’ve gotten all of the binders and books scanned. The software is fully captured and I’m trying to create a “build environment” for this as a demo. I’ve tried to get Windows to work properly in various combinations of virtual environments with limited success. I’ve used Parallels on the Mac, VirtualBox on the Mac and PC, Bochs on the PC and Microsoft Virtual PC on the PC. I have a complete log of my findings if anyone’s interested. Only Parallels on the Mac worked completely. On Microsoft VirtualPC under Windows 7, it almost worked, but button clicks didn’t register. Bochs was the worst performer. Most of the issues have to do with capturing the mouse — Windows 1 predated PS/2 mice so a mouse has to be mapped to the virtual COM port or the InPort bus interface, which the virtualizations seemingly do with limited success and not at all, respectively. Some had problems with MSDOS 3.31 diskette images or 32MB virtual hard drives (the limit for DOS 3.31). Others had issues booting Windows under DOS 5. Has anyone successfully gotten Windows 1 to work within any virtual environment with working mouse support? If so, what was the exact software configuration so that I can replicate it here? Thanks!

Big rescue!

We haven't had any huge awesome big-iron rescues for the museum lately. There's nothing in the hopper, honest! Just that whenever I say it out loud, something tends to come up. :) So here's hoping...

Decserver 300 PSU schematic?
by David Hoelzer 28 Apr '16

28 Apr '16

Does anyone have any thoughts on where I could find a schematic for a Decserver 300 power supply? I just picked up a 300 but there’s something wrong in the PSU. The capacitors look ok, though they are quite old. Normally I’d just replace them, but there’s pretty much zero output even though I see no fried components anywhere and there are 120 volts coming in. Thanks!

MAC with squashed screen
by william degnan 28 Apr '16

28 Apr '16

I am thinking about working to repair the display on my '84 MAC, occasionally the horizontal is "squashed" although for now it recovers. Was this covered in any VCF E classes this or last year? http://vintagecomputer.net/browse_thread.cfm?id=95 I assume there are a few places on the web that describe MAC repairs like these, but any comments as to what to target are welcome and will save me some time. b -- @ BillDeg: Web: vintagecomputer.net Twitter: @billdeg <https://twitter.com/billdeg> Youtube: @billdeg <https://www.youtube.com/user/billdeg> Unauthorized Bio <http://www.vintagecomputer.net/readme.cfm>
