Microbee BN54 4kb ROM - ChickenMan - 10-12-2020
Thanks to kimjohn for making this ROM available to be dumped and scanned.
This rom came in a Series 2 64k (actually only 56k) Microbee and was a 2732 EPROM. I have also recently seen the same labelled chip in a 2532 eprom in the same model Microbee. It was just labelled as :-
** 2732 **
D-Boot v54
The code is identical to the normal 56K 2532 ROM thats in the repository but differs from the first 4kb of the normal BN54-43 rom, but only in the first few bytes. Added to the repository for reference.
Also collected in the past were a few other pictures of other ROMS, so time these were put into the Repository. Thanks to Hans, DavidM and the internet for these.
So in the MbeeTech Repository in the Microbee/Software/Roms/Boot folder we placed
bn54_2732.rom
bn54_2732.jpg <-- in the Documentation\Pictures\ROMs folder
