Microtan technical reference
Hardware and expansion manuals
TAN-DOS, Colour VDU and Mousepacket video-board documentation for the Microtan 65.
These documents cover several of the Microtan’s more substantial expansions: the TAN-DOS floppy-disk system, the Mousepacket Colour VDU and the ETI real-time clock/calendar project. They complement the original system manuals and the technical-reference material elsewhere in this section.
The current Linux/WSL2 emulator implements the Mousepacket 384×250 display and later TANBUG/BASIC firmware. It also emulates the optional TAN-DOS controller with eight logical drives backed by raw disk images and the ETI real-time clock at its published example address. See the current emulator page for its present capabilities and links to the implementation notes.
