The A1000 depends on a lot of external circuitry to handle bus arbitration and the things that need to be done to direct certain memory reads to CHIP ram and others to FAST ram. On the B2000/A500 all that stuff is done by Agnes (that's why she's put on weight). This means that the external pins to Agnes are completely different than the pins on a Fat Agnes or Fatter Agnes. Even if you added one additional address line to your A1000 and if you could* ignore all the other lines BUT correct the timing on the similar lines; it still wouldn't work. The only way to get a working Fatter Agnes is to sell your A1000 and buy an B2000 or A500. -Tom * -- You can't. -- Tom Limoncelli -- tlimonce@drunivac.Bitnet -- limonce@pilot.njin.net Drew University -- Box 1060, Madison, NJ -- 201-408-5389 Standard Disclaimer: I am not the mouth-piece of Drew University
