I've got two RL02 units. One is a parts unit and has an access plate for the door solenoid. I can open it. The other has no access plate nor is there a cutout for one. How do I open this cover with the power off? This is a newer unit as it has head lock screws on the bottom of the drive. The second question has to do with rack mounting. I want to mount this in a H960 cabinet but will obviously need to slide it out to replace packs. All the unit has is a thin rail on both sides that is riveted to the unit. It looks like chassis slides were there originally. Does anyone have either the DEC part # for the slides or a contemporary part # for one that will work? Thanks, Marc

Data IO 29B / Unipak 2B adapter?

by mattislind＠gmail.com

I need to read a couple of Signetics 82S215 bipolar PROMs with my old Data IO 29B / Unipak 2B. But it needs a 351B-068 adapter. Does anyone has information regarding this adapter? I did find an old post in DATA_IO_EPROM at groups.io mailinglist that a man named Alfred Marin had boards. I even found his email but it bounced. Any other pointers in this subject? /Mattis

X11 expertise on ancient HW sought... (4-plane visual (overlay) via X-server on MS-WIndows)

by dimitris.theo.gr＠gmail.com

Sorry for undiggind this subject so many years later, but have you found a solution to your problem? I am facing exactly the same issue, and i have tried all possible windows X server options without success. The only possibility I am working with is with a Mac OS X server, which reports a 5-bit visual.

Foonlies

by lars＠nocrew.org

This document seems to imply that the Super Foonly and the Foonly F1 were separate machines. When I've seen them discussed, they always seemed to be uses synonymously. http://www.bitsavers.org/pdf/dec/pdp10/KC10_Jupiter/memos/foonly_19840410.p… SUPERFOONLY DESIGNED 1968-71 10,000 TTL IC'S 3 MIPS F1 (1978) 5,000 ECL IC'S 3.5 MIPS Also, except for the CCRMA F4 at Computer History Museum, does anyone know about any Foonly machine having been preserved?

where to find ZCPR2, ZCPR3, ZCPR33, ZCPR34?

by spacewar＠gmail.com

I've become interested in ZCPR2, 3, 33, and 34, and am surprised at how difficult it is to locate them online. Or maybe I'm just an idiot. Are they out there somewhere? It looks like ZCPR3 was on SIG/M volumes 184 to 192, but those specific volumes seem to be missing from the SIG/M archives I can find. I'm specifically NOT looking for NZ-COM or Z3PLUS. Thanks! Eric

Sneak peak: this year's VCF PNW/East/West shirt design

by cctalk＠snarc.net

Here's a sneak preview of the shirt design for all of the 2018 Vintage Computer Federation events. As usual, each event will have a different shirt color. Dan Roganti aka Ragooman used to design the VCF East shirts. Any similarity to him or his interests in the current design is purely coincidental. :) https://vcfed.org/wp/wp-content/uploads/2018/01/pnw-shirt-front-1.png

It's possible that they are there somewhere and I just didn't find them. Apparently NZ-COM and Z3PLUS are based on ZCPR34, but are fancy auto-installing things with no source code, whereas what I'm looking for is the original ZCPR2, 33, and/or 34 distributions that included source code.

A couple of RL02 questions

Does anyone > have either the DEC part # for the slides I sent these to the list a while back, and never added them to the CHWiki once we gained access to it; I have now added them there: http://gunkies.org/wiki/RL0x_disk_drive#Installation Note that i) they are handed, so one needs an L and a R (I have extra lefts, and would like to trade some for rights), and ii) the same slides are used on other DEC drives, e.g. the RA81.

NCR7510 Bootmedia (Tape)

by harten＠injectstar.de

Hi to all! I'm looking for a boot medium for my NCR 7500. It is the model with one cassette drive (standard MCs) and the monitor in vertical position. I think this model is called 7510 and there should have been at least an OS "BASIC +6". Regards Rolf

Bluebox boards, anyone?

by dave＠661.org

Would anyone like a bluebox PCB or two? This project was inspired by Don Froula's ProjectMF[1] in which he presents a PIC-based bluebox[2] and PCB (handed out at HOPE in 2008). A big reason I like AVRs more than PICs is because the development software is OSS and free. So I reimplemented Don's bluebox in C for an AVR ATtiny85. The PCB started off an a drop-in replacement, but evolved into something designed to fit into a Hammond 1591XXM box instead of functioning as a lid for a Radio Shack 230-1801 box. The Hammond box also comes in transluscent blue! The firmware code[3] is done. I just have to do some tweaks once some test PCBs[4] are made because on the prototype, I wired up the keypad a bit strangely. The code implements a 13-key bluebox, a DTMF keypad, a redbox for US, Canada, and UK, greenbox, and 2600 dial pulse. The PCB needs work to correct some early design decisions that turned out to be non-optimal.

Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
