Quick question: my ROM03 IIgs has a Transwarp GS, SCSI card-hard disk and GGlabs 8MB RAM card. Think this would work with that configuration, or would it likely have conflicts?
I have the exact same setup except for the SCSI card and it works with that. The issue will be if the SCSI card is in one of the slots that has been virtualized on the FPGA (4 and 7 by default), in which case there will be address range conflicts. For example, if the SCSI card is in slot 7, then it will conflict with the SuperSprite functionality which uses the address range for Slot 7. There is a "No-Sprite" version of the firmware which disables the SuperSprite or you can move the SCSI card to Slot 3 and put the A2FPGA in Slot 7. ROM03 GS units have the necessary address line signals that the A2FPGA needs on all the slots whereas previous models of the GS only had those on Slot 3.
