Cosmonics

Provides all of the capabilities of CIOUTIL, but 6 times faster. Writes data to cassettes and reads data from cassettes at a speed which is 6 times faster than the TS1000/ZX81 SAVE and LOAD commands.

CFASTDATA and CFASTLOAD. When both programs are used, you may LOAD programs and data at a speed which is 6 times faster than the TS1000 and ZX81 LOAD and SAVE commands. CFASTLOAD can be configured to your needs.

Utility to selectively read and write strings and arrays to a cassette. Routines occupy approximately 500 bytes and require at least 2K RAM.

Many vendors sold ZX80/ZX81/TS 1000 compatible edge connectors in solder-tail and wire-wrap versions. The wire-wrap connector could be used with a small printed circuit board to build a feed-through device that would allow for connecting another expansion unit.

Construct an RS232/TTL level converter from inexpensive components. This converter, when used with the Cosmonics TTL Serial Input/Output Port Package, allows connecting a TS1000 or ZX81 to most RS232C peripherals.

Plans and parts to build a serial output port using two integrated circuits. Plans also available separately.

Provides RS232 input timing and ASCII to Sinclair character translation.

Provides correct RS232 timing and translation to ASCII.

Software and plans for building input and output ports which fit inside a ZX81 or TS1000. When used with an RS232/TTL level converter, can connect to most RS232C peripherals.
