However, I'm curious to know if it supports an HCF (Halt and Catch Fire) opcode
As a matter of fact, one of my earliest Magic-1 ISA designs included an HCF instruction along with an external output bit (similar to the 1802's Q bit) that HCF would set. My plan was to use that bit to trigger a flashing red fire alarm on the front panel. Sadly, I dropped HCF in a later revision.
