Yes, the A500 has an RCA jack for composite monochrome output in addition to the RGB output. To my perception, it is essentially free of objectionable flicker when used with a medium/long persistance green or amber monitor. I've seen suitable monitors advertised in the computer shopper for $75-150. Note that different people have different threshold levels for flicker. You do need a longer persistance monitor - with "TV" speed phosphers it's not much fun in interlace mode, although it's fine other modes. Further note that composite monochrome is not the same a "PC Monochrome", composite monitors were being sold for monochrome graphics output from a PC CGA card a few years ago, but that's died down since the Hercules clones made better PC graphics available... -- 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)
