DEC PDP8/A Vintage Computer by Digital Equipment Corp PDP - $2,700 (Pansey)
QR Code Link to This Post
Made by Digital Equipment Corporation in the late 1970s.
32K x 12bit Core memory. (Not semiconductor, real core.)
It does run. I keyed in the first test routine from the manual, it increments a location in core, then increments the accumulator each time the core location overflows. With this running you can display the AC and watch it increment. Of course that's not a complete test, but it is a decent indication of health.
The only I/O installed is the basic serial/parallel on the M8316, I have not tested that nor do I have a cable made for it, but we could probably make a serial cable here and send/receive a character by poking registers from the front panel, if a buyer wished to.
Modules installed:
M8315 KK8A PDP-8/A CPU board
M8316 DKC8AA PDP-8/A I/O serial/parallel/clock
M8317 KM8AA Probably is a M8317YC KM8AC PDP-8/A Memory extender, bootstrap, powerfail
Two each of:
G650 MM8AB PDP8A 16K Core Memory stack
H219B MM8AB PDP8A 16K Core Memory control
Located about 20 miles east of lovely Dothan Alabama.
If this listing is still here, then I do still have the PDP8.
