What about the other way around adapters?

One is an "original-clone" of the Promenade-C1 by the way :-) A friend of mine made some clones back in the '80s because we couldn't in general afford original hardware down here. The first defective clone was mine for free if I could fix it. And I did fix it. Another programmer I have (Data I/O 21A) can read and program the MCM6876x (and the ricoh cmos, but not the 27HC641) but I think the programming algorithm for them is buggy. I'm in touch with the person who has all the old Data I/O documentation to try to make a fix for it. The Promenade still rocks with those old EPROMs :-) F Message was sent through the cbm-hackers mailing listReceived on 2016-07-12 18:00:02
