<This reminds me of the Intersil 6100 which had a special "front panel" mod <designed to hold code and data to run the (presumably flashy) front panel. Same for the 6120 (has EMA interally). IT was presumed due to the micros lack of front pannel you would need startup code or emulation code. <would be getting a 6100). I did the design/layout/prototype of a 6100 CPU They can be found especially the 6120 version. If not a DECMate is a good source(they are hardly rare). Allison
