It gave me a bit of a headache getting my head around it when I was first doing this and I ended up cheating and just modified the corsham variant of the code (particularly as that system was already very similar to the one that I was adapting for) because I wasn't sure how to create my own ...

Another OS ticked off the bucket list - CPM-86 ... now working with the Fujinet on the MECB 8088 board:

The only board without an OS now is the 6502 ... I'd have to admit it is my least favourite CPU to play with. Perhaps once I tidy up a few loose ends with ...

I have the fujinet library now ported across to the 8088 board:
Next challenge is to see if I can get some OS ported across to work with this (it's hard to find anything that can run on a generic 8088 that doesn't look and behave like an IBM PC).

Now working my way up to the 68008 board. Ported across the Fujinet library to work with it, wrote a very basic BIOS, and was able to boot up CPM 68K v1.3.

It took ages to get to this point - mainly because the information available for this OS on the Internet is a complete dog's ...

After quite a bit of messing about I managed to get NitrOS9 booting off FujiNet (and fetching the network time).

I got thrown off on a bit of a wild goose chase with something I still don't quite understand - the FujiNet library was a bit too big to fit in the OS9 kernel with a 4 KB ...

I found a kind of work-around for cross-compiling - I can compile on my main computer using asl and then in FLEX type "MON" to enter Digibug, load the S1-format output, do a warm start of FLEX "G CD03", and then a "save FILENAME,HEX-BEGIN,HEX-END,HEX-EXEC" - that saves it on to the FLEX disk. I ...

I'd have admit that it has only been lightly tested but thought it best to post whatever I have so far (before I get distracted) in case it is useful to others (LOL, in helping their wishes come true). I managed to get trek and Othello running on the DigiBug 6800/2 system so posted those as well ...

Going back to the 6809 board for a while (just because it is easier). Managed to open up a network connection via the FujiNet interface and read the contents of a web service I made for work (it returns the positions of the planets at the time the query is made):

FujiNet module tests ...

I've now got FLEX 2.0 (and 3.0) booting off "the Internet". with FujiNet using drivers I've written for the MECB 6802 board (now updated with DigiBug):

I've added the drivers to my 6800 GitHub (including the boot disk and some Python tools to read FLEX ...

Some slight improvements:

- Doubling of sector size no longer required (the driver will now adjust for the difference in sector size).
- Fixed a few minor bugs in the error handling.
- The boot process is a single-step process now (load the boot loader and run).
- Verified that FLEX can access ...
