Can I please have some help with a Frame Grabber board for the Amiga 2000? The problem is as follows: I'm using the example circuit from the A2000 technical manual for the bus interface. Having built and tried the circuit I'm unable to get it to work! I've tried using a logic analyser to monitor the bus signals which seemed to indicate the lines expected to be active during the auto-config sequence differred from the PAL equations supplied in the manual. Does anyone know if these PAL equations are correct or if there are any problems with this example design. If any can help with a better design or reference manuals that explain bus interfacing for the ZORRO2 please post to this news group or on Email. Trevor Email Address TNEWMANDA@CC.CURTIN.EDU.AU
