Overnight housing @ VCF East
by Evan Koblentz 27 Apr '18

27 Apr '18

I emailed the overnight housing info to all exhibitors, speakers, vendors, and official volunteers just now. Chances are good that I missed a few people. If you think you were supposed to be on the list and didn't get the email, then send me a private message (evan(a)vcfed.org) ________________________________ Evan Koblentz, executive 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

NiCad coin cells?
by Neil Cherry 26 Apr '18

26 Apr '18

I'm busy resurrecting a Toshiba T100SE. Unfortunately I've found the Ni-Cads to all be dead, The main battery pack is a 7.2v 1700mHA pack (6x1.2v) and then there's a RTC backup battery which is made up of Ni-Cad coin cells (2.4v, 4x1.2v but made up of 4 cells). Anyway I can fudge it with a couple of AA Ni-Cads I have. This is just to make sure it starts up the Intelligent power supply is very picky about the batteries. I currently have a kludge battery pack of AA Ni-Cads (with twice the mAH - hehe) and I'll build a temporary RTC battery out of 2 AA Ni-Cads. So my questions are: - Does anyone have any recommendations for building (or rebuilding) the battery pack? - Any recommendations on the coin cell part? -- Linux Home Automation Neil Cherry ncherry(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies

BYT-8 MPU
by Mike Loewen 25 Apr '18

25 Apr '18

I have what appears to be the CPU board for a Byte Shop BYT-8: http://q7.neurotica.com/Oldtech/S100/ByteMPU-2.jpg BYTE 4-76 MPU C1000-1001 ASSY REV A It appears to be missing a ROM chip, and has definitely been hacked on (weird voltage regulator or transistor in lower left). Is it worth putting this up for auction on the site-whose-name-shall-not-be-mentioned? I also have an unbuilt PCB.

NeXT Cube for VCF museum
by Evan Koblentz 25 Apr '18

25 Apr '18

Everyone, We're still searching for a NeXT Cube to put in the museum as a permanent exhibit (currently we have a slab/station.) I would like to get this accomplished in time for VCF East. Normally we only accept donations, however once in a blue moon we accept loans for "very special" artifacts. Does anyone have a working-and-clean Cube they'd consider donating or at least putting on long-term loan for the museum? If so, then please contact me off-list (evan(a)vcfed.org) Thanks!!

Re: [vcf-midatlantic] Last call for this weekend's workshop April 28/29

If I came up, could someone help me diag a problem with one of my Lisa's 3.5 drives? There's something goofy with the spindle speed regulation, and I know it's not the drive. Probably a fault with a logic chip on the io card. Might need to break out the scope.

forum posting problem
by W2HX 24 Apr '18

24 Apr '18

Hi guys. I just spent an hour working on a post on my PDP-11 project. I was reviewing it when I clicked on one of the inline images (as attachment) to see how it looked. It brought up the framed hop-up with the image. I clicked the image within the hop up and the browser now showed the url for the image directly. No hop up, no forum in the background. I then went to click "back" to continue editing the post and I got a blank white page. I went back several times just to arrive back at the original "REPLY TO POST" when I began with no sign of the hour of work I did. Nothing I could do would get it back. Anyone know if the draft is stored somewhere? Is there some place I can go to view my drafts and continue on? Otherwise, very sad! Eugene
