  • P75 SCSI BIOS BINs - where?

    From Louis Ohland@21:1/5 to All on Tue Sep 13 07:44:19 2022
    https://www.ardent-tool.com/8573/P75.html#P75_System_Board

    Even 79F3214 SCSI BIOS Even
    Odd 79F3213 SCSI BIOS Odd

    So where are the BINs?

    Just for the record, the 44/45 SCSI BIOS fits just fine.

    To be sehr klar, the P75 uses two 32Kx8 OTPs. Quite possumble IBM was
    able to use 64Kx8 OTP on later systems, therefor saving money.

    SWAGgering about, maybe they used the 32Kx8 size because it was well
    supported? no redesign or testing?

    Also, why use the two part Hirose sockets? Not aware at this time of any
    other systems with that socket.

    Tim burndt me the latest Tribble ucode of 41G9974 14h/20d date 1992.

    The bad part is that most 386 to 486 motherboards were just upgrades to sell more shit
    with the "486" Logo... " faster is better".. Look at the model 95 cpu cards.. (not early 33 mhz"

    after 66mhz"s}
    All of the bus speeds were the same Clock didn't change..

    same shit faster cpu's different day 3-4 G Vs 5G on cell phones .. Now

    just to sell some new shit
