Hi All,
Well, after around 18 months part-time worth of stuffing about I finally got round to completing my own version of a tiny PC clone (well, the first version anyway..)
Piccies of the 'FLEA88' system box..
Front view:
Rear view:
Internal view:
Things added to the emulation firmware:
* Added virtual disney sound source, connected to the virtual LPT1 (look mom, no wires!) So now the PC speaker, Tandy Sound Gen. and Disney audio values are summed equally in firmware and sent out through the host audio DAC.
* Keyboard and mouse virtual interface improved considerably
* Int 10h video functions now largely complete, though some tiny quirks remain
* Hard disk write handler now complete so that high scores can now be saved (among other things), will need further testing
* Serial port COM1 now functional, albeit with basic support at the BIOS level only..
* CPU Trace Interrupt (01h) functionality added and fixed a stack (no pun intended) of CPU-related bugs..
Due to increasing time constraints, I've decided to keep the expansion possibilities to a minimum for the above showcase model.
Managed to get the firmware ready in time to showcase the system at our local (Amiga-oriented) computer user group over the previous weekend, where the response was quite positive overall.. No event pics unfortunately, as I had to leave far too early - oh well there's always next month..
Anyhow that's all from me for now - gotta get back to conqu... uh, I mean beta testing!
Cheers,
Valentin
