Thanks, all! I'll start digging into clock ICs and see if anything looks like it matches what's in there. - Josh On Sat, Jan 20, 2018 at 11:03 PM, Ethan Dicks <ethan.di...@gmail.com> wrote: > On Sat, Jan 20, 2018 at 9:06 PM, Josh Dersch via cctalk > <cctalk@classiccmp.org>

ISO: Harris Micro-12 (HB-61000) docs

Hi all -- Got me a Harris Micro-12 (AKA the HB-61000), this is a single-board computer based around the Harris 6100 (PDP-8 on-a-chip) microprocessor.  I'm working on bringing it back to life and I'm trying to find docs and schematics for it. There's a high-level overview starting on page

Hi all -- I've got an 11/03 backplane here (designated as an "11/03 EA" originally but marked as "Model changed from EA to AA") inside a small chassis w/power supply, model "OH780-A."  (So it was at some point in its life the front-end to a VAX-11/780.)  As far as I can tell, it has a

Identifying TO-3 w/HP house numbering

Hey all -- Got an HP 2382A terminal I'm attempting to resurrect. I get no video, no heater, no high voltage. What I believe to be the horizontal output transistor appears to be bad, but I'm not sure if this thing contains internal diodes that might be throwing off my testing attempts. It's

Re: Ethernet names...

To the best of my knowledge, at the time it was developed at PARC in 1973/74, it was referred to as "Ethernet" (or "The Ethernet") and later was referred to as "Xerox Experimental Ethernet" likely to differentiate it from the developing 10mbit standards... - Josh On Tue, Oct 2, 2018 at 10:47 AM
