| 2068 Power Supply: Make It Cooler & Quieter | I have discovered that programs SAVE’d to cassette tapes from the TS-2068 can have a very high noise/scratch background level making verification and loading a somewhat iffy proposition. The best way to determine if you have this problem is to monitor the signal on the tape aurally during loading. The background noise can be heard […] | Timex/Sinclair 2068 |

| Analog-to-Digital Sampling Routine for the TS1000 | An 8-byte Z80 machine code routine stored in a REM line for use with the ZEBRA Analog-to-Digital converter, suitable for low-speed sampling (once every several seconds). The disassembled code reads a specified port, delays for A-to-D conversion, and returns the result in the accumulator. A sample 10-reading BASIC wrapper is included. | Timex/Sinclair 1000, Type-in program |
