ZX80 ZX81 TS 1000
Modular interface system to permit real-time application of the ZX80/81. Connected by motherboard; 5 modules available. The RD 8100 is a modular interface system capable of performing a wide variety of scientific tasks, when coupled with a Sinclair Computer (ZX 81 and Spectrum). Flexibility and compatability are built into the system, which is simple to
ZX80 TS 1000
The VOTEM was a hardware/software package that could measure, display and record real world analog signals via the cassette input. Any physical phenomenon (pressure, light temperature, etc.) that could be represented by a DC voltage could be measured. The name of the product came from the fact that it could measure VOltage and TEMperature. The

ZX80 TS 1000
Clear vinyl keyboard overlay with holes for each key.
ZX80 TS 1000
Two different keypads available, matching double H keyboard. Both are assembled but unwired, so you can use them either for numerical keypads or as extra keys.
ZX80 MicroAce ZX81 TS 1000
ZX80 TS 1000
Vinyl overlay for Sinclair keyboard with punched holes to aid in data entry.
ZX80 MicroAce TS 1000
Allows “touch typing” and improved game playing. Made of clear, self-adhesive vinyl with key-shaped rectangular holes for easy finger positioning and tactile feedback.
ZX80 TS 1000
Miscellaneous
Digitizing tablet originally designed for the ZX80. User would have been able to write on the table and have the output appear as characters or draw on the tablet and output as graphics on the screen. The tablet was eventually available for Atari computers.
ZX80
Turn ZX80/MicroAce into a machine more powerful than the ZX81, e.g., run with either 4K or 8K ROMs.
ZX80
Power
Protect all ZX80/81 ICs if voltage regulator fails by crowbar and fusing.
ZX80 TS 1000
Printer
Designed exclusively for use with the ZX81 (and ZX80 with 8K BASIC ROM), the printer offers full alphanumerics and highly sophisticated graphics. COPY command prints out exactly what is on the whole TV screen. Printing speed is 50 characters per second, with 32 characters per line and 9 lines per vertical inch.
