Wow, I know it's not a DEC PDP but I was hoping at least a few people used the darn thing. Would it be better if I post in VCF? Thanks for any input. -Ali

> From: Ali Fahimi > Wow, I know it's not a DEC PDP Hah! Don't feel too bad. I've lost count of the number of PDP-11 questions which I've brought here, only to hear a resounding silence (most recent case on point, my query about Clearpoint DCME/Q4E's). Noel

MARCH's Straight 8 restoration notes

by evan＠snarc.net

The RICM PDP-12 thread made me realize that I (nor I think David Gesswein) ever posted our PDP-8 notes here. (We did post a link to the Youtube video of the ceremony at VCF East.) Anyway, here are David's notes: http://www.pdp8.net/shows/vcfe15/slides/PDP-8_Restoration.html and also his exhibit notes here: http://www.pdp8.net/shows/vcfe15/vcfe15.shtml.

WANTED: HP 3000

by mloewen＠cpumagic.scol.pa.us

I worked on HP 3000 systems in the late '80s, and would like to find one for my collection. A series 42 would be nice, but a series 37 or micro XE would do. Any leads? I'm already aware of the one on Epay in Florida that's been sitting at $1,725 for the past year. I'm in central PA.

WANTED: HP 3000

by COURYHOUSE＠aol.com

Mike - this would be a good complete system for you Mike and good it has tapes. that may have the little cartridge drive in it too but beware the cartridge drives they seem to all have gummy capstans... I ruined a fos tape put it in... got error... pulled it out and looked like it was slimed with the 'black oil' like in x files! there is a work around for this though using some glue and rings on the capstan roller after you scrape the goo off. having the large tape drive is better anyway. like this unit has. Our aim here at SMECC is to get data off our old tapes fro the company days and also our bulletin board system we wrote that had 100 separate boards, email, voting and poll system multi user chat we let other 3000 system managers in the 80s use... it was really something in the pre-internet days. Mike - there should also be a full file of all the hp-3000 stuff that Marlys Nelson developed I always thought it would be fun to finally get a series 68 or 70 but... yikes the power bill would hit you and the cooling....Yikes! for the same reason we want a series II or III or CX for the museums display but to keep it under power 24/7 with a string of drives costs $$$ and especially when you consider the air conditioning ! I have a 37 cpu and a 50 meg drive but of course need recon fig it which means cold load tape as the other drives in the string are missing I can not it past the point of disavowing the other drives that do not exist. Fun time here with the manuals etc... I have not had my hands on A WORKING 3000 for over 22 years I think. A lot comes back but there are some head scratching still going on! OK have the cart tape drive with goo capstan and have reel to reel tape drive that when at initial power-up it just spins the reels. What do we need? spare cpu more little disk drives 50 meg will not hold the store set from 1986 Known good reel to reel hpib tape drives 1600 bpi ok as that is what our store set is in and any of the other reel to reel tape distributions contributions and found stuff was. I will keep an eyen out for east coast stuff for you and appreciate if you keep an eye out on west coast stuff for us! pretty fun with drop box we can share programs without having to ship tapes to each other!

It was last booted about 2 years ago when another list member was trying to his a system running. Is is mounted in one of the short / narrow HP racks with 3x670H HPIB drives. I think the total disk size is about 1 Gb. That seems like a ton for a system that small. I also have a HPIB 7980 front loading tape drive, that I would include in the deal. AND... I have the original 9-track system tapes (FOS), some spare NOS tapes (let me know how many you'd like), the original MPE documents on CD, and I could probably dig up some MPE paper documentation as well. I am in western NC but could be coaxed into meeting you somewhere closer (possibly southern Virginia). I'll take an offer but, be warned, I'm not giving it away.

Clearpoint DCME/Q4E configuration

by jnc＠mercury.lcs.mit.edu

Hi, does anyone know anything about the configuration of these boards? (The document on BitSavers only covers the Q4B; the jumper configuration on the Q4E is totally different.) They are 4MB quad QBUS memory cards; PMI capable, I'm pretty sure. I have two of them, one of which came out of an 11/84 (I never saw it in the machine, though), and is so probably configured to run PMI. The thing is that I stupidly mixed it in with the other one, and now I don't know which one is which - and they are jumpered differently. It doesn't have to be full (or any) documentation; if someone had one they _knew_ was jumpered for, say, PMI operation, I could copy their jumper setup (or see if one of mine already had the same). If not, I'm going to start in on drawing a picture of all the jumpers, and see what QBUS/PMI pins they are all connected to - looking at the card, there's a big row of jumpers next to the pins the PMI is on, and the jumpers are all 'on' on one card, and all 'off' on the other, so I suspect the one card is jumpered for PMI operation, and the other, not. So, even if there no documentation extant at all, we should be able to more of less figure out what many of the jumpers do, and start making use of these cards. But any help/info would be gratefully received! Noel

docs or software for Quay 900 (uses Quay 90F/MPS board)

by spacewar＠gmail.com

Does anyone happen to have documentation, schematics, or software for the Quay 900? It's a system based on the Quay 90F/MPS single-board Z80 computer and two MPI double-sided 8-inch floppy drives. The drives are MPI part no. 77618022, apparently a 9406 variant but not listed in the drive manual on Bitsavers. I suspect the pinout is close to the SA800/850 pinout (industry standard), but I was surprised to find that none of the variants in the 9406 manual have a pinout similar to that.
