I have a file here ..It's one I downloaded from John Dale's excellent Flaxcottage archive.
It's a CEEFAX emulator recreating 80's frames (maybe some genuine pages from the early 1980's are there)
Whether it was built much later or not is no matter it's a great time capsule, and would be a great
addition if I could run it from within my BBS.
There are a couple of issues though. I have copied it over to ADFS and it won't run.
I can't get at the code and I suspect it is hard wired in the machine code to run DFS only.
I wouldn't know where to begin disassembing this though. I am little out of my depth.
A *INFO on the file gives
006000 006000 00129A 003
It's not a big file and the pages it carousels around are loaded frames from the disk.
My BBS Host theoretically can call this program. although I'd need to make sure is it doesn't
rob the Host of the dedicated memory workspace it uses , being
&70-&CFA and &7600 upwards ..HIMEM is set at &7600 and can't be changed.
In theory ( if I am correct ) I need to
Get the file to run in ADFS ( having copied over with CopyF it wont run).
There is an !BOOT file there to call the program, or type *FAX1982
Make sure it doesn't rob my BBS Host of any workspace when running.
Somehow create an interrupt or key press command to return to the BBS Host.
Essentially something which will execute a CHAIN command to recall the BBS.
I managed to get a MODE7 BASIC game to run within the BBS Host recently although
I did have to change some of the code particularly related to where some things where printing
on the screen. The program wouldn't display things normally so I expect there were some clashes
of screen workspace.
Any help much appreciated guys.
thanks
Brian
