By the first sorry if I write in English - I'm from Italy - barely read your messages by guess but writing or

using google translation seems not ok fo rme, since one time found Your group resolutive I try again...

Hi, I found one of such multimeter at a flea markt but the eprom 27c256 is gone (reads all 00s)
does anyone have a rom image (the eprom label is: U212 DMM).

The multimeter logic board have the space for the installation of the 488 interface,
but without components, probably for the '488 model will be useful a different rom. (the 2510G model)
The interface between the multimeter logic and the 488 interface is made by two
optocoupler so a simple two way, two wire link (interesting, may be connected to an external micro w/o 488 ...)
I not will bad have a service manual(the schematic will be ok), but curiously its easy found a really old servman
(the '5xx tubes scopes) but not this one...(maybe oldies products lasted more longer than newest?)
The logic is based on a 8031/2 micro (one time my preferites) instead of dedicated chips and also the 488 interface(my guess),
in this case a simple 7106 may be replaced with another one but with micro the hardware is not the all ! (fortunately is external
rom)

Can someone help me?
bye & TIA
