Hi folks, I tried alt.sys.pdp8, google, and AEK's site, but I can't for the life of me find any schematics for the PDP-8/I's Extended Arithmetic Element. Can anyone help out? See http://www.parse.com/~pdp8/pdp8i/restore.html for the ongoing saga :-) Cheers, -RK -- Robert Krten, PARSE Software Devices +1 613 599 8316.
