Hi Askild,
thanks a lot for the clear and detailed pointer.
With "nonvolatile trace memory" mentioned in the manual, I thought of something
more durable (EEPROM, FlashROM) than a battery back-up SRAM :-) Would have
been nice, if the programmers had added some CRC or at least a checksum to the
data compression throwing an error message if something fails. At least they had
time for the famous "Tetris game" :-P
As the price tag for the M48Z128Y replacement from Maxim is in the $30 range,
(and then you dont't know how old it is already) I'm thinking of setting up a
"discrete" solution with a $3 128kSRAM, a coincell and 2 Schottky-Diodes
(or a DS1210).
Cheers??? Andreas
