|

FloppyOne DOS Interface
|
||||
(c) 1984/5 Rocky P. Gush
|
||||
|
||||
FD1791-based floppy drive and printer interface with 4K RAM and 8K ROM
|
||||
Was mainly designed as tape replacement, and sort of emulate how tapes works,
|
||||
which allows to copy and use most of existing software and (not protected) games with no modification.
|
||||
|
||||
Doube-side drives considered as 2 separate floppies (0 and 4, 1 and 5 etc) probably to mimic tape sides A/B,
|
||||
disks is password protected.
|
||||
|
||||
Main commands:
|
||||
!D=n - change current drive, where 'n' 0-3 = FDD 0-3 side 0, 4-7 = FDD 0-3 side 1, 8 = enable LOAD from tape
|
||||
CAT - list disk contents
|
||||
LOAD "name" - load program, LOAD "" will load first program (unless was disabled by !d=8 command)
|
||||
LOAD *"m";1;"name" - same as above
|
||||
SAVE "name" - save program
|
||||
!FORMAT "diskname";"password";tracks - format disk, if disk was already formatted you'll be prompted for password.
|
||||
!6=n - set text mode, 0 - regular 32-column, 3 - 64-column
|
||||
There is more of special "!x=n" commands, but theirs functions is not known, manual is missing.
|
||||
Some information about this device https://worldofspectrum.org/forums/discussion/42944/rocky-gush-floppy-drive-interface/p1
|
||||
|
||||
Notes / TODOs:
|
||||
- Interface1 compatibility mode is not well understood and not fully implemented
|
||||
- Serial printer interface not implemented

|

Speccy-DOS Interface
|
||||
(c) 1987? Philips(?)
|
||||
|
||||
WD1770/2-based floppy drive interface with 1K RAM and 8K ROM,
|
||||
presumable developed by Philips & MBLE Belgium, had some popularity in Hungary.
|
||||
|
||||
Main commands:
|
||||
LIST * - list disc contents
|
||||
LOAD *"filename" - load and run program
|
||||
SAVE *"filename" - save program
|
||||
FORMAT *"diskname"dd80 - format double side double density 80 tracks disk
|
||||
ASN *drive# - change drive
|
||||
|
||||
Manual: https://sinclair.hu/speccyalista/konyvtar/kezikonyvek/SpeccyDOSv4_manual.pdf
|
||||
|
||||
Partially compatible with Spectrum128, useable after "USR 0" from basic128 or switch to 48K mode.
|
||||
|
||||
Notes / TODOs:
|
||||
- address decoding performed by large DIP28 chip, probably PROM, not dumped, exact logic is not known.
|
||||
- program ROMs have swapped data lines/bits 1 and 5.
|
||||
- original software disc mentioned in manual is missing.
|
||||
- Magic/NMI function require NMI routine preloaded in RAM by "MAGIC2.x" program (which is missing).
