I have a 16500B logic analyzer that fails the startup RAM test. I took a look at the CPU board, and the SIMM slots are unpopulated.
Does this machine have RAM soldered on to the main board and extra RAM is provided through the SIMM slots, or does all of it come via SIMMs?
Does anybody have some specs on the SIMMs used in these machines? I've so far been unable to dig up detailed information on what they require.
Thanks!

The SIMMs were 1MX36 modules. The ROM stored all of the power-up
routines and the power-up self-tests and the disk drive instructions and
the HIL driver. A RAM test failure usually meant a faulty SIMM module
first and if the SIMM module was good, then a faulty microprocessor board. I would expect a RAM test failure if the SIMMs are unpopulated.
