Is it possible to cook up a circuit which gives you an A500-style monochrome output from the A1000? Preferably only passive devices, and preferably not disturbing the RGB signal. I'm tempted to go the two-monitor route; my Sony and a cheap monochrome. George? Thanks! -tom

Well, you could probably get the same effect with a little bit of snipping by connecting the luminance output of the 1377 to the composite output buffer transistors. However, I suggest you try simply plugging a decent monochrome monitor into the composite color output and see if the result is good enough for your purposes. While, the A500 monochrome output is ineffably better (since I designed it), the A1000 output isn't all that bad. You may want to mess with preferences to get a better color-monochrome mapping for workbench and simple text applications. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
