Do any of the GM OEM OBD1 MEMCALs have removable proms or are they all permanently attached?

All MEMCALs have permanently-affixed chips; the main PROM, the backup PROM, and the knock filter.
The only ECM that comes to mind with a removable chip is the one in the '85 Corvette, the 1226870. But that's not a MEMCAL, so yeah.
