I realized I had not posted my Tektronix 4052/4054 Checksum Program on my repository, so I added that folder here:
https://github.com/.../tree/master/4052-4054_ROM_Checksums

This program requires the 4052/4054 Diagnostic ROM Pack or Jos Dreesen's design for that ROM Pack:

My program uses the Diagnostic ROM command CALL "CRC" to compute the ROM checksum for a selected bank address and length, with results that match the published 4052/4054 Checksums. The A-Series 4052A/4054A ROM that I have is v1.5 which is the latest version I have seen. My 4052 has v5.1 ROMs which are the latest version published by Tektronix service notes.

My program also reports the 4050E01 ROM Expander installed option ROM CRCs - which is emulated by Jos Dreesen's 4052/4054 Multifunction ROM Pack which also adds Tektronix RS-232 Printer Interface and TransEra Real-Time-Clock hardware:

Here are screenshots from my 4052 and 4054A running this program:
