Thanks

The easiest way is to set DELAY 2 (all displayed messages are "paused" for 2 seconds) or whatever you fancy.

TEST32KE LEX is what CMT had on the module from Factory (64k modules would have TEST64KE), as are the two with EPRM*** and the CLONE program.

The command in TEST32KE is ROMTST which will tell you if the ROM is OK or not OK.

If your Google CMT71-P01 you will get to know a bit more about the EPROM Burner and the programs just mentioned

Add: The reason I know a bit about this - without owning a ROM-Burner, is that I have spent some time understanding the EPROM and Burner. I have an open agreement to meet an owner of a working CMT71-P01 in Switzerland as soon as the C-19 pandemic tapers off...

So how many burners were made and are still in service I wonder?

Ok, so SHOWPORT shows the module is 64k but ROMTST says 'BAD ROM'. I've tried a few commands and they appear to work.

Could this be because it's the wrong test (the 32k test is loaded on a 64k module)?
