Shows what you don't know. Non exhaustive list of micros with debug roms:

PDP-11/03, 11/23, 11/73, 11/83, 11/84 (most all the non front pannel 11s)

SC/MP
IMSAI IMP-48
Kim-1
SYM-1
AMI EV68 series
Motorola 6800D1 and D2
intel SDK-80/85/88
SWTP 6800
ALTAIR-8800b (the front pannel is in a 1702 prom!)
Godbout 8080/front pannel replacement (octal keypad!)
Netronics Exploror 8085
CCS 2200 series s100 crate
Heath H8
Micromint SB180 (z180)
Intel MDS-800
Intel MCS-8 (8008)
MicroVAX series including VS2000, 3100, 4000 and others.

I am very certain I've left a truckload of them off.

Also if the PC had rom basic there are instruction in basic that allow
access to memory, IO and machine language subroutines.
