This is a call to anyone who has a Solartron 7081 and has saved a copy of their ROMs (if you haven't you may end up in the same boat as I am - the one that's up the creek without a paddle).
One of the ROMs on my earthy processor board has died. It would appear that the ROMs in this 7081 were updated to a high level of firmware at some stage in its life as the total ROM image size is greater than that of a set that was copied by Bill Ezell from his 7081 even though his meter has a higher serial number (461) than mine (180). The ICs in question and the CRC16 checksums (in hex) for my ROM set are: IC430 3238 IC415 C5C0 IC414 1260 <===== It is this one I want IC413 B958 IC412 ED50 If you have saved your firmware ROM images, and the checksums for your ROMs match these, I would be immensely grateful if you could send me the image for IC414 (the middle one of the three). If as a result of reading this message you feel impelled to save your ROM images and find your checksums match these ... Obviously if I can't find a good image of that ROM, I'll just install the older firmware, but one never knows.
