This was my dream computer. It was stunning and was upgradeable to CP/M. WOW! In fact, it is still stunning. Probably the sexiest computer I have ever seen. I bought mine off of ebay for a song several years back. Works great too, with the exception of the keyboard. From what I can see, a 74LS something chip needs replacing. I will do a post of the repair at some point when I get round to it.
