I'm a long-time CP/M enthusiast and still have my original Ferguson 'BigBoard'.
More recently I made an RC2040 and three Grant Searles.
I built a Z80MBC2 and its ok, but I much prefer the 'Z80 Playground' by John Squires as it has a modified CP/M
which uses FAT and therefore sidesteps all the faffing about with CPM Tools, download.com
, xmodem etc.
Copy files from your PC to the USB stick, insert it into the Playground and the files are there under CP/M.
This convenience is a really Good Thing and hence my 'other' CP/M boards dont get anything
like the same use. It runs everything except (obviously) direct disk editing programs since the format is abstracted by the custom BDOS.
WordStar, Turbo Pascal, BBCBasic, Hitchhikers etc all run perfectly as do my usual tools M80, RMAC, ZSM etc
John seems to have lost interest in the Z80 Playground project which is a great shame as its my favourite of all my Z80 gear.
I did an 8255 PCB for it since the lack of I/O ports was its only shortcoming.
Thinking about it, the Z80MBC2 hasnt been powered up at all this year, the Playground is so much nicer.
