Sorry- right idea but it didn't come out right. An REU used on a C64 should NOT have a resistor at R4. An REU used on a C128 SHOULD have a resistor at R4. If you are using a 1750 on a C64, remove the resistor at R4 (leave it open). -- -- Fred Bowen uucp: {uunet|rutgers|pyramid}!cbmvax!fred arpa: cbmvax!fred@uunet.uu.net tele: 215 431-9100 Commodore Electronics, Ltd., 1200 Wilson Drive, West Chester, PA, 19380
