I bought some spare 5372A CPU boards. One of them failed the histogram hardware test. Looking at the histogram/timing board schematic, the only histogram specific chips on the CPU board seemed to be a decoder and a couple of buffers. I replaced the decoder and the problem got worse with several more tests now failing.
The ROMs are 5372-80032 .. 80039 _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
