The BBC Master was purchased for several reasons, to assist with my own Hardware projects and to help produce the Electron User Groups by monthly discs. The Master had a 40Mb Hard Disc Drive and a 186 IBM PC 2nd processor with 500Kb of RAM.

The purchase of this machine allowed me to add a Hard Drive to my Electron.

At the request of a fellow Electron and Master User I designed a small ROM expansion board for the BBC Master - it basically converted the two 32K ROM sockets to four 16K sockets to allow better use of the ROM allocation.

Still looking for a photo of the IBM 2nd Processor..
