Peter Broughton 512k Enhanced BIOS v2.2 Preliminary Manual for the Microbee - ChickenMan - 09-06-2022
Thanks to kimjohn for making this document available to be scanned. Scanned at 300dpi and converted to a searchable PDF as usual. A4 in size and 8 pages long.
This was written by Peter Broughton in Jan 1987 and Jan 1988 for his final operation system ver 2.2 for 256k & 512k memory upgraded Microbee's. See the 512k_memory_upgrade_notes_by_peter_broughton.pdf on how to upgrade your 64k or 128k Microbee's memory. From this manual :
The operating system can be used on all Microbee 256k and 512k
computers, that is, 64k CIAB's or 128k's that have been upgraded
to 256k or 512k. In addition, it will work on a 128k computer
although not all of the system's features can be used. It will
not work on a 64k computer, neither will it work on the 256TC
(Telecomputer).
This is a Preliminary document and not all sections have been completed but gives a good rundown on the new functions available compared to the original Microbee system.
So in the MbeeTech Repository in the Microbee\Documentation\Articles\Technical folder we placed
