  • Sun2/120-170 Boot PROMs

    From [email protected]@21:1/5 to All on Sun Apr 15 13:07:57 2018
    Anyone have the 1.X version of the 68010 Multibus boot PROMs stashed away?

    I could really use the extended test menu as I go through the stack of old boards collecting dust downstairs.

    Thanks,

    Steve

    O.K. I've got a 2/120 out in a storage shed -- but way too far
    back, behind newer systems and I'm not sure which version of PROMs it
    has, or whether I could read them into a file for easy e-mailing if I
    could get to them.

    Do you know which EPROM family it uses?

    Good Luck,
    DoN.

    The boot proms are a pair of 27128 or 27256 EPROMs (even and odd bytes). All my boards had common pre-SunOS 4.0 version N or R chips. The "new" proms are 1.something. I've seen 1.1.2 mentioned.

    My Rev R versions were marked 520-1101-03 and 520-1102-03, with the 1101 being the odd and 1102 being the even. In the FE handbook they are marked as 8 and 0 (the low order bits of two bytes making up the 16 bit word)
