For those of you who own the TS2068 and bought it in anticipation of the micro-drives, the wait is over. The interface just plugs on to the back of the computer as would the printer. It has a connector on the back to allow for the attaching of the 2050 printer or modem. There are…

As an avid Timex/Sinclair “computerist” and pastor, I am convinced that the computer does indeed have a bright future in the church, and that every church can reap enormous benefits from owning its own system.

One of the best features of the BASIC language that Sinclair designed into the ZX-81 (TS-1000) is its ability to SAVE all of its variables, including arrays, in the normal course of SAVEing the program onto cassette tape and reloading the variables along with the program LOAD. This allows us to transfer a file, in…
