My 5370B PROM turns out to be fine (there was some operator error) I picked up a DATA I/O 201 programmer and some NOS windowed MOT MCM68764C to have some backups (this was probably overkill, since I have never actually seen a failed hp counter from ROM failure)
A newly burned MCM68764C appears to work perfectly. The programmer reports SUMCHECK 7387 for U3, 5370B Ser. No. 2438A 01154 The programmer can report in the following formats: INTEL INTELLEC 8, INTEL MCS-86 HEX, MOTOROLA EXCERCIS, MOTOROLA EXORMAX, and TEKTRONIX HEX I can read these formats to a text file using a Windows terminal emulator to save them to a file, however, I do not know how to make the ROM Image. I was hoping to be able to say something about the ROM version, but I do not know how to compare the files I get to the available 5370B ROM image? The DATA I/O 201 does not appear to directly save the binary file. I can supply a few replacement 5370B ROMs at cost plus shipping if anyone needs one.
