| VDAQ1 | Votem Data Acquisition – Hi-Res. Written VOTEM, a simple voltage-to-frequency converter, designed for single-channel analog data acquisition. Allows multi-screen acquisition, variable scale and timebase. Without the VOTEM, it was useful for frequency measurement, via the tape input jack. 16K. | Timex/Sinclair 1000, Downloadable |
| VOTEM | 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 | Sinclair ZX80, Sinclair ZX81, Timex/Sinclair 1000, Timex/Sinclair 2068, Downloadable |

| Intro to I/O | Here are a couple articles that introduce you to control applications for the T/S computers (ZX81, TS1000, TS1500) with a minimum of effort and (best of all) at reasonable cost. Before we control something with a computer, we usually need some way of getting information back to the computer; ie, to control an oven, the | Timex/Sinclair 1000 |

| The Votem | The Votem, to play on James J. Carr’s book Digital Interfacing to an Analog World (Tab Books, Summit, PA. 1978), is an analog interface to Sinclair’s digital world. Analog/Digital Conversion Analog (related to analogous) refers to relationships by ratios. The analog device relates numbers to a turn on a wheel such as our rapidly disappearing | Timex/Sinclair 1000 |

| Timex at the Heart of the Kidney | TS1000 plus peripherals can make life easier and less expensive for artificial kidney patients and US taxpayers. Artificial kidneys used by dialysis patients cost $20-50 each and patients can use each only once. Each kidney patient must dialyze, using a new kidney, three times a week.

| VDAQ - A Data Acquisition Development Program | Here is a program that demonstrates a simple yet effective way to get analog information (data) into your ZX81/TS1000/TS1500 computer, with a minimum of additional hardware. Also included are various plot and display routines so you can get visual and printed output of your acquired data. Along the way it will show you various “tricks” | Timex/Sinclair 1000 |
| Votem Cassette Controller | If you have a VOTEM, or if this article talks you into buying one, here is a simple modification which will extend the board’s utility further, and allow you to start LOADing a program from tape, flip a switch when the loading bars appear on the screen, and walk away; when the program has loaded, | Timex/Sinclair 1000 |
