Yes, definitely an MST-80. There's a (very basic) page dedicated to this machine here: http://online.sfsu.edu/~hl/c.livermore.html, you can see from that picture that it is the same type of board (although the keypad is a different colour). The web page says the processor is an RCA 1802, others have mentioned an 8080. paul -----Original Message----- From: Robert Borsuk [mailto:rborsuk@colourfull.com] Sent: 28 March 2003 18:02 To: cctalk(a)classiccmp.org Subject: Re: What is this? eBay #3409766995 Is it an MST-80b?
