This is how it looks like, the USB interface MEP Application 3 from Spellbound.
Features:
The module is fully integrated into the PC-1600 operating system and represents the memory stick as an S3 device.
This makes read and write access as easy and natural as with a RAM disk S2.
Supported standard commands:
FILES, [B]SAVE, [B]LOAD,COPY,KILL,NAME,OPEN,PRINT#, INPUT# ,CLOSE Plus two additional commands from the module's ROM extension:
CDIR: Change the directory on the memory stick (UNIX style)
LDIR: List the subdirectories of the current directory.
Modular design with interchangeable front-end hardware.
UART Rx/Tx communication between frontend and backend with up to 57600Baud.
Backend:
ATmega32A microcontroller with I/O port communication (INP/OUT) to PC-1600 with application code
28C256 EEPROM with socket. Contains PC-1600 ROM extension
22V10C PLD with socket. Provides addressing:
ROM extension at #7,&4000, microcontroller port: &90
Onboard SPI socket for programming the microcontroller
Compatible 60pin bus connector.
USB front end:
Hobbytronics USB host controller with pre-installed application - compatibility:
SHARP PC-1600 only.
PC-1500/A is not supported - the module must not be connected to a PC-1500/A!
