CMT71-64E HP-71b eprom module questions
Hi all

Does anyone have any experience opeining up these modules, removing the eprom and then erasing/writing new data to them ? I understand there is a purpose built eprom programmer that is very rare and therefore not an option. Another forum user has kindly offered to write them for me but I was trying to avoid burdening someone else, especially difficult given I am a half a world away in Australia.

I would love to know what these look like when pulled apart and what eprom is installed. Perhaps it could be desoldered and written with a newer usb eprom programmer?

Any comments appreciated

Cheers

Richard
