    I can send you a dump, if you have a burner.

    There's a set of ROMs advertised on eBay at:
    http://cgi.ebay.com/IBM-5150-PC-BIOS...QQcmdZViewItem

    They are listed as 5150 ROMs, but are obviously 5160 ROMs (only two ROMs, copyrighted 1986, and labled U18 and U19).
    Seller told me that he pulled them from a 5150 and that's why he has listed the ROMs as 5150 ROMs. Must have been a 5160 motherboard in a 5150 case.

    My three 5160 motherboards have the third BIOS revision, 05/09/86, with all the BIOS chips having the part numbers of "59x7268" (U18) and "62x0819" (U19).

    The eBay chips have diferent part numbers and have a 1986 copyright. That suggests that they are the second BIOS revision, 01/10/86.

    If you had the ROM dumps, I don't think you could simply burn an EPROM and put it into the socket. IBM used non-standard ROMs in the PC.

    I hope you get your ROMs, and maybe update us on what you are going to do with them, what your favorite machines are, etc.

    Yes, the 5150 ROMs are a pain, but 27256 EPROMs can be used for the 5160 and 5170 ROMs.
    You have to ensure that you use EPROMs of an adequate speed. For the 5160, the EPROMs should be rated at 200nS or faster.
    I don't know what the required speed is for the 5170. It will differ between the 6MHz and 8MHz motherboards. All 5170 motherboards where I've seen IBM use EPROMS rather than PROMs, use Intel D27256-1 EPROMs (which will be 100nS).
