No I had the right connection and baud rate, turned out to be Putty - I had some settings left over from NIBL that seemed to mess things up ! It seems to be working OK though I couldn't get Putty to send CR/LF so the printer would only print when it had a full line ?

Anyway I'm happy that it works - back on to finishing the other projects before starting another !

thats right but I only used two wires, ground and receive (marked TX). The printer has a separate power input lead which I temporarily ran to a 2S 18650 lithium. No 'return' signals from the printer at all, just signal & ground. At 9600N81, CR & LF work fine on this one, either via Teraterm and an FTDI or via the MK14 or RC2014

Could it be a linux "lines end in LF" problem, whereas Windoze uses CRLF?

Its a great little toy for £15, you wouldnt LIST Startrek on it but for the novelty of incorporating a tiny printer Aim65-style its great!

BTW according to Wiki, "The AIM-65 is essentially an expanded KIM-1 computer", I didnt know that
