Zawieszone, pokazalem projekt na WOS, Velesot mi zrobil liste, cytuje :
Exist also other variants of new betadisc clones. I have also one unfinished project. Original design of betadisc is OK, but not so good at this time. Need some modifications...
- unusable on +2a/+3 models
- small incompatibility with zx48 models
- tr-dos rom need possibility of reflash (too much tr-dos versions contain big bugs..)
- betadisc rom in modern zx clones use often 32kB instead 16kB only.
- impossible use in combination with divide/divmmc interface
- incomplete ports addressing
- bad NMI
- this betadisc version is incompatible with kempston joystick, fuller joystick, UR-4(PIO), SAA1099 interface...
... etc ...
But as single device connected to ZX128/grey +2 it's OK
With small modification will possible also implement CP/M support.
Wiec skoro istnieja inne wersje i to sie da poprawic to nie bede wywazal otwartych drzwi. Poczekam i kupie sobie gotowe jak juz bedzie zrobione .
