Thread: Looking for SWTPC SWTbug ROM

    Default Looking for SWTPC SWTbug ROM

    I have a SWTPC 6800 computer that is missing the monitor ROM. Does anyone have a spare Motorola MC6830 or is able to burn a copy of the SWTbug program to a compatible EPROM?

    If you can't find the actual SWTBUG ROM, you'll probably have to use an EPROM adapter to program a standard EPROM yourself. Unfortunately, the pinout and chip selects of the MC6830 are very different than standard EPROMs.. Mike Holley designed an adapter a number of years back. Here's a link to his adapter.
