No, that dump is the MS12 with serial IO, not the older version for the hex keypad/display.
I have both the original article from the Maplin magazine for the Keypad/display as well as an original unit in a box in the shed (somewhere), so all I am missing is the ROM.
The 2716 EPROM I have in this card has some fun code in it...the original application was a twin 35mm slide projector controller for a military project back in the early 90's, but that setup didn't use the keypad or display - just some funky I/O stuff.
A hexdump of the original M12 rom would be fantastic, SH.
