Re: PDP8/a Initial Power Up (Columbia Valley Maker Space)

Hi, Most of the documentation is found here: http://www.bitsavers.org/pdf/dec/pdp8/pdp8a/ For some basic testing look here: http://www.bitsavers.org/pdf/dec/pdp8/pdp8a/EK-8A001-OP-002_PDP-8A_Operators_Handbook_Sep76.pdf in chapter 5.1 (pdf page number 48). To do basic memory read and write:

Re: Updated Spacewar for the PDP-8/I, 8/E, etc....

I used Lyle's updated version to show Spacewar on my PDP-8/a during this weekends retro event "RetroGathering" in Sweden. It works great! I did two modifications to the code: 1. Use digital IO instead of the switch register so I could use hand controls to let the audience play the game. 2.

BASF 8" floppy drive documentation and alignment

Re: PDP-8 core memory problems.

So what are the other options? * Trying to repair the unit. Every plane is soldered together with the ones nearby to convey the X/Y signals. This can probably be undone with a patience and soldering braid. But what are the chance that the X/Y wires gets lose then? Are those soldered or welded
