41cx doesn´t recognise 319 registers Message #1 Posted by Gonzalo Fernandez on 28 Nov 2004, 11:28 a.m.
I have an HP41cx fullnut that after doing SIZE 000, shows only 255 (it is missing 64 registers). I have reset the calculator with no luck, only shows 255 registers instead 319 registers. Also, EMDIR shows 124, so extended memory is OK. What memory chip/chips (upper, lower or both) I must change to repair the memory? Please see the photo http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5733774885&ssPageName=STRK:MEWA:IT
to let me know which of the 5 top memory modules I must change (each memory module comprised with two soldered chips)
thanks!
