Yet Another ZX-TS Fix

Do you have any of the following problems with your ZX81 or TS1000?

1. “Built-in NVМ” of SWN 4:1 does not properly run WRX16 hi-res.
2. Certain keyboard lines go dead after installing a large keyboard, joystick plug, etc.
3. Erratic operation when adding certain peripherals, even though you KNOW you have an adequate power supply.
4. The TS2040 printer gives your system a fit.
