Hi Bob,
Use this link to see all the files in that folder including my microcode zip (should match the microcode ROMs in Jos' zip) and my doc on reading the old Motorola ROMs:
http://www.bitsavers.org/pdf/tektronix/405x/4052_4054/firmware/
The MAS ROMs zip are the BASIC EPROMs on the MAS board. The 4052A/4054A updated the MAS board to replace the ROMs and Patch ROMs with EPROMs and replaced the discrete GPIB circuit with a TI 9914 GPIB IC.
I just noticed the MAS ROMs zip is shuffled pairs of EPROMs into a single binary file which can be examined with a binary editor like HxD.
When you get your 4054A to pass the power on self test - you should be able to use the Option 1 serial interface (or manually enter the program) to load in my Checksum test program which will check your BASIC ROMs against my version 1.5 BASIC ROMs.
Here is a 4052/4054 Microcode Power Up Test Sequence service bulletin that I posted on my repo that may help:

And the System Test Fixture doc link I posted is from a microfiche that contains the original 4052/4054 microcode disassembly listing with comments! It also contains even more details on the PCB LEDs and Connectors with detailed power up steps!
