[volt-nuts] HP 3458A Mem test 1 hight. How do you read 32K memory chips?

[Mark Sims]

The problem with removing the chip and copying it is the very real chance of glitching the contents in the process.  Much better to make a backup copy first.

The 32Kx8 NVRAMS are used for system memory and things like storage of user programs and data.

Note that the two 32Kx8 devices are form a 16-bit word.  The 2kx8 cal ram is only on the high byte of the data bus.  MREAD returns memory contents as a signed integer value (-32768..32767) in ASCII.
