If you are having problems, the first thing to check is that your SCSI bus is terminated correctly. If you have a single hard drive connected to the card, the bus should be terminated at the hard drive, either using internal termination resistors or a piggyback terminator on the unused connector on the drive enclosure. It is also necessary for at least one device to supply power for the termination. The Apple SCSI cards didn't originally do this, because supplying termination power has the potential to place heavy load on the Apple II power supply. Apple added termination power on later releases of the High-Speed SCSI card, and it can be retrofitted to earlier models by soldering a diode onto the card. If possible, you should use a hard drive which supplies termination power. All the Quantum drives I encountered did so, but I don't know what the situation was with other brands. The FAQs for comp.sys.apple2 may contain some useful information in this area. If you appear to have correct termination, you might like to try changing your SCSI cable - some are better quality than others. > I understand I need the Rev.

You might already have the latest firware (revision C). 341-0112A is revision A 341-0112B is revision B 341-0437-A is revision C If you currently have revision A or B firmware, upgrading to revision C gives you some bug fixes, adds support for a limited range of CD-ROM drives, and allows the card to be used under GS/OS on an Apple IIgs. It also allows you to use a wider range of software. For example, "Chinook SCSI Utilities" will only support this card if revision C firmware is installled. If you are using the card in 8-bit mode on the IIgs (or on a IIe or II+) then you should be able to get it working with reivsion A or B firmware, using the partitioning software supplied with the card (HDSCPARTITION). Upgrading the firmware requires replacing the EPROM on the card. You will need to get hold of a 27C128 EPROM (16K bytes), a copy of the firwmare image, and find someone who can burn the firmware image into the EPROM. (Incidentally, revisions A and B use a smaller 8K byte EPROM, so you can't erase and reuse the one that came with the card, even if that would be a good idea.) -- David Empson dempson@actrix.gen.nz
