From the layout and text font, I'd guess Sundstrand (CNC machine company)

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
