From the layout and text font, I'd guess Sundstrand
(CNC machine company)
but usually they put their logo/name on boards. I only have
Unibus
Sundstrand boards in the shop at the moment, but none of them have that B
logo. Wouldn't be surprised if the B logo is from whoever made the boards,
as in the actual board fab house.
Thanks,
Jonathan

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:

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
