Default Re: Retro computer homebrew: Orton Karenbak-1 computer

Thanks for that! I've been through my TTL box and very few HC IC's. I've got plenty of LS though. They should be OK shouldn't they? Just a bit more power?

On the spreadsheet, the ones highlighted in red are the LS versions of the HC ones in the computer.

I don't mind the drilling so much as centre popping all the drilling positions through 0.1" squared paper! One dodgy hit and it all goes wrong - you can't re do it!
