You don't have the 'production' version of the CPU service manual with
the microcode source do you? I only have the pre-release one which
says that's to come later :-(
Actually, do you mean P854 here? The P854 panel is a keypad with a
pair of vacuum fluorescent displays (address and data) controlled by a
8048. The CPU was built from AMD 2900 series chips and included a
memory management unit. I've never heard of one with core either.
