    Question Identifying an 8 Bit SCSI controller (settings, driver)

    Hello,

    I got an 8 bit SCSI controller using LSI 53C80 SCSI controller chip (same as in ATARI TT/Falcon). Besides that it has 5 TTL chips plus 2 PAL/GAL chips with stickers.

    I would like to have MS-DOS-drivers and settings for SW1 and SW2.

    SW2 should be a 4 bit decimal (0-9) switch (5 pin layout), set to "7" - SCSI controller initiator ID??? SW1 numbered 1-6 has A9-A4 labels on the pcb, that might be adress settings. There is also unpopulated JP1-4 for IRQ 3,4,5,9(=2, AT-cacade).

    The board is labeled

    GSII-PC REV:E 9331
    P/NO:510018-04

    And a paper based sticker on solder side "002020-V.E."

    Anybody able to help?

    Hello, I got a little step ahead, here is the jumper settings: http://ambrosia60.selfhost.eu/53f8ee...e/KGSII-PC.CIS

    In other forums (vogons) and older posts here they (and even some of you still here) talked about a generic ncr5380 ASPI driver. Does anybody have it? I ncould not find a download through Google.

    Give the drivers for the Mediavision PAS16 or the Trantor T128 cards a try. The 5380 was used in a lot of early SCSI adapters.

    Or even the DTC 3180 SCSI cards. Failing that, write your own driver--the 5380 detailed documentation is online in several places. It was a very common chip in SCSI applications.

    FWIW, SCSI IDs are binary: 0-7 for narrow SCSI and 0-15 for wide SCSI.

    I found driver for Trantor T128 but not foe the others now. But it's proprietary driver, no compatibility to ASPI. I'll test it. Anyhow, if anybody has a driver with ASPI support, it would be welcome.

    Do you have a copy of the Adaptec EZSCSI suite? I believe it has a T128 driver.

    I have EZSCSI packet, but only with Adaptec's own SCSI card drivers. Maybe you can share with me?

    I'll have a look, but my recollection is that since Adaptec bought out Trantor, that the T128 drivers should be there also. Adaptec re-named the Txxx to MAxxx, but they're the same thing.

    Here are the Trantor ASPI drivers

    Is that card bootable?

    It has no BIOS, so it's not.
