hello,
i am a beginner in this forum, i think that i have selected the right place to ask my question,
so, i have a old philips PM93 that is working like a charm, but the fluke 93/philips PM93 are missing the print function, but have the RS-232 Optical IR port.
i have already build the IR transceiver for pc (here is the link http://omapalvelin.homedns.org/fluke/ (http://omapalvelin.homedns.org/fluke/)) to connect to my philips PM93, and Scopegrab 32 detect my scopemeter but it can show anything and return "cannot change to 9600 baud".
after a lot of research, I concluded that the PM93 and PM97 have the same internal components (EPROM, microprocessor...) !
so i think that the difference is just in the firmware or the software.
my question, if i put the PM97 firmware in PM93, is it possible to have print function ?
thanks in advance

just to show pictures of internal PM93

Hi, would it be possible for you to dump the eprom content as the one in my PM93 has been corrupted

I'ld urgently recommend to replace these electrolytics. Once I owned a scopemeter of this heritage and its demise started with these caps leaking, finally resulting in (at least that's what I assume after considerable time spent testing) a failed bonding wire in the LSI Logic chip -- which sealed its fate.
BTW: Mine was a PM97 and it had both EPROM footprints populated. During failure analysis I had both the chips out and read them. For the rare event anyone might find the contents useful, here's the archive!
