Any way to disable ON+CLX on the 41?

[Geir Isene]

Could the ON+CLX=MEMORY LOST be disabled in any way? MCode?

I think you might be able to intercept it if you put custom microcode in block 4, where the diagnostic ROM normally would go, though I haven't checked. However, this would be incompatible with the 82160A HP-IL module when the printer function switch on that module is turned off, as it relocates the printer ROM to block 4.
