**CAUTION! UNTESTED – WORK IN PROGRESS – UNDER CONSTRUCTION** ``` RC-2104 compatable z53c80 SCSI Controller with Config Jumpers The Config jumpers were added to allow the card to work in Target Mode, Using a modified version of the SCSI2IDE firmware. The card uses 9 I/O Ports from 04-0Fh to F4-FFh One port (x4h) is for Config jumpers(read only) Eight sequential ports (x8-xFh) for the z53c88 Default for testing with SCSI2IDE firmware: 84h for Config jumpers 88-8Fh for z53c88. AH = 9-10 (80h - 9Fh) AL = 1-2 & 3-4 (Config = 84h - z53c88 = 88-8Fh) ``` ``` AH I/O Base 1-2 00h 3-4 20h 5-6 40h 7-8 60h 9-10 80h 11-12 A0h 13-14 C0h 15-16 E0h AL 1-2 Config = I/O Base + 4h 3-4 z53c88 = I/O Base + 8h 5-6 Config = I/O Base + 14h 7-8 z53c88 = I/O Base + 18h ``` ``` 2N7000 & SCSI-INT header are Optional SCSI BUS TPWR jumper is only closed if you need to provide Terminitor Power to SCSI Device or If the SCSI Device is providing Terminitor Power TPWR-FUSE & 1N914B are only needed it the card is suppling Terminitor Power RN1-3 are only needed if you are not using an external Terminator ```
