Unix demo @ Bell Labs - June 5
by Evan Koblentz 15 Aug '19

15 Aug '19

This is tentative / not yet 100%: Bell Labs (at the historic Murray Hill, NJ location) is planning a Unix event on Wednesday, May 5. They invited us to do a mini-version of Unix Town that afternoon. Important details: - We'd probably have five or six tables. - This is NOT a public event; it's invitation-only by BL. - Our goal is to do demos for important people. So I'm gauging initial interest: who is able to take a day off from work that afternoon and come to NJ for this?

[OT] 14" Atari ST/Amiga CRT recommendations
by John Heritage 03 Jul '19

03 Jul '19

Greetings Offtopic - so please reply privately as to not clog up the list; I was curious what people would recommend for a CRT monitor that could support either or/both an Atari ST (1040STf, Mega STE) and/or an Amiga 500/1200. Ideally I'd like something 14" in size, but larger (if reasonable/easy to use) recommendations are appreciated. Thanks! John

Hello: I picked up a Sun 3/50 that works fine but I need a mono crt for it. I'm wondering if anyone here has experience with them and remembers if other monitors work or what the specs are with them. I have a keyboard and am getting a mouse. thanks, -andy

InfoAge had about 15 visitors today; half of them made it to VCF-land. One guy introduced himself as Jason Howe's cousin. So that was exciting. :) Bill I. came by to visit us.

Looking for schematic for Tandy HD
by Richard Cini 30 Jun '19

30 Jun '19

All – I just obtained a 25-1025 10MB external hard drive unit for my Tandy 2000. There is a relay inside that powers the unit on when accessed from the controller. Unfortunately, one of the relay coil leads has come undone (the trigger, not the ground) and I don’t know where it goes. Does anyone have a schematic of the power supply or a copy of the service manual, or a link, so I can fix it? Thanks!

Pet Help
by David Hoelzer 28 Jun '19

28 Jun '19

Hey- My life is still in turmoil, but I decided to have a go at my PET before moving it on to a new home (yes, some of you know who I'm looking at). At this point, it is semi-conscious again... but... I appear to have a strong clock, phi1, phi2, and there appears to be data appearing on the data lines of the 6502 (see the logic analyzer output). The display, however, is not happy looking. Additionally, while the display in the photo looks awesome (compared to complete darkness), it will randomly flicker to darkness or perhaps even go dark for long periods. Nothing is particularly hot on the board, I just burned a complete set of EPROMs (and verified them), and I've been over the board three times looking for solder joints, etc. When the screen goes dark, the tube is still glowing, so I'm guessing that it's a video circuitry problem, but I'm stumped as how to tell if it's on the board or on the CRT board. (This is a 2001-N 32k..) Any suggestions? I know we have some PET pros around here. Photos attached. If they don't go to the list (I don't remember of they do) ping me and I'll send them direct. -- ---- David Hoelzer Chief of Operations Enclave Forensics, Inc.
