Emax

You’re looking at the wrong item(s).
Emax 1 and Emax 2 don’t have a circuit to flash / update the main EPROMS.

In addition, parameters like that aren’t stored in the boot / system EPROMS, they are held in the 9306 Parameter EEPROM IC 24.

Kind of like the PRAM in a MAC, but this you don’t ordinarily want to unset. When it becomes unset, then it’s Scrambled Megs…like what you describe.

I'm working on three 8MB Stereo machines that have lost their memory size allocation.

I have one working 8MB Stereo unit that I copied the EPROMS from (IC19 and IC20) and wrote those binaries to the other machines.
They still give the memory size error message, and show incorrect memory sizes, so something else has been overwritten besides the EPROMS.

I wonder if its stored somewhere in the O.S. as well. Since the HD's are not working on the broken machines, I'm using a floppy to boot them. I have no idea where I got that floppy, as I've owned pretty much every configuration of Emax at some point, but that would explain why this isn't working.
