My ICT-101 lacks the ROM/RAM test. According to the manual (thanks again to Pat/John for making the scan happen) - G, "RAM TEST/ROM TEST INACTIVE - Without the RAM/ROM Test Options installed (available from Micro Sciences), the ICT-101 in its - standard configuration is unable to test memory chips. Thus, without the appropriate option - installed in the ICT-101, the above message(s) will be displayed. I uploaded some pics of my ICT: https://postimg.org/gallery/2sv3lagbu/ I'm curious how it differs from anyone's who has the RAM/ROM test feature present. I'm not sure if it's one of the missing chips on the upper board, or within the potted contents of the lower pcb Any help gratefully appreciated.
