Help ID'ing a PDP-8/A Omnibus board

by derschjo＠gmail.com

Hey all -- Got a PDP-8/A at VCFW this past weekend. It's an OEM model sans programmer panel and was apparently used in a CNC application. It contains a board I'm trying to ID. It says "PDP-8/A CONSOLE ROM" on it and has no other identifying marks other than a logo on the back. See the pictures here: http://yahozna.dyndns.org/scratch/pdp-8/8aconsole1.jpg http://yahozna.dyndns.org/scratch/pdp-8/8aconsole2.jpg <http://yahozna.dyndns.org/scratch/pdp-8/8aconsole1.jpg> None of the braintrust at VCF were able to identify this mark. I'd guess that the board provides a simple ODT interface or something similar. The three ICs in the upper-left with the handwritten labels are 82S129 256x4 bipolar PROMs. They're not socketed so I haven't read them in yet. The 8/A's gonna need some TLC before I dare power it on... I'm mostly curious if anyone can ID the logo -- it would be interesting to know who made this thing. Thanks! Josh

ADM-3A question

by charlesmorris800＠centurytel.net

I bought an ADM-3A on ebay. The monitor and the circuit board/keyboard are >from two different terminals - confirmed by hand-engraved serial numbers on the halves that don't match. Not to mention the two different case colors (pale blue top, blue bottom)! But it does have the lower-case option already installed :) Anyhow, there appears to be some breakdown of the CRT implosion plate silicone (screen rot). I've read about this problem before, so no real surprise It seems to be turning into brown "goop" which has run down onto the circuit board. Do I need to remove the goop before powering it up? Or is it nonconductive and hopefully noncorrosive, so it can wait until I remove the implosion plate and fix it? thanks Charles --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Only part that simulation doesn't let you do is to connect up all sorts of lab hardware to A/D's and D/A's. Have lots of PDP-11 code that wrote in 1980's that can't use as no-one has written additions to PDP-11 emulators which will make one think one is dealing with 80's era data acquisition hardware and digital I/O boards which are far faster on modern microprocessors than there were then. Well, you say that, but?.. I just ordered https://obsolescence.wixsite.com/obsolescence/pidp-11 <https://obsolescence.wixsite.com/obsolescence/pidp-11> , and it contains a prototyping area now so you can do stuff like https://obsolescence.wixsite.com/obsolescence/pidp-11-temp-barometer-hack <https://obsolescence.wixsite.com/obsolescence/pidp-11-temp-barometer-hack> . But, I mean?that?s a modern micro that looks to the PiDP-11 as if it were a Unibus peripheral, so it?s a decent model for what you want to do. And then there?s the Unibone?.http://retrocmp.com/projects/unibone <http://retrocmp.com/projects/unibone> if you want to drop some modern stuff into a real Unibus backplane. Adam

eBay: PDP-8/A KL8A serial line card

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > $325?? Well, they did list it with a 'Best Offer'. I figure the third time they get an offer of US$100 (or whatever the thing is actually worth, I don't track PDP-8 board values), it might become clear to them that they are way optimistic on the value. I once had to wait a year for an eBay seller to come down to a semi-reasonable price on some RK05 drives... Eventually they gave in. Noel
