Fair warning, this is half as much on tindie.  Search there for sbc-85.

This listing is for ONE 2732A EPROM which has been preprogrammed with one of the shared programs available on the Home » Bits Of The Golden Age website. The most current version available will be programmed.  specify version 1.x or version 2.x SBC-85 hardware since the memory mapping is different.  If for version 2 hardware, I can also put dunfield's at ORG 0x0000 and the confidence test at 0x1000 into a 2764. that way you can use a second 2764 in the expansion ZIF at the same time.  just let me know what you need.

Pick one of the following:

1) Dave Dunfield’s MON85 (ORG 0x0000)

2) Craig Andrews’ SBC-85 confidence test (ORG 0x0000)

4) JMP 1000H (literally this one instruction than jumps the program up to the ZIF socket).  For example to run the confidence test at 0x1000 without the MON85 in the base socket.

5) Dunfield's MON85 (ORG 0x0000) PLUS Andrews' Confidence Test ORG @ 0x1000 in 2764 or 27128 EPROM for v2.x hardware

This is for any one pre programmed EPROM, specify how many and what you want programmed into each one.

Of course you can get either the Willem PCB6E programmer or Martin Eberhard’s orphan programmer, download the code from the Home » Bits Of The Golden Age website and program yourself.

Shipped with USPS First Class Package. Combined shipping, ask for invoice.
