ANOTHER SOLUTION TO RAM PACK WOBBLE

Kelwood computer cases has two computer stands - the Wobble Stopper for the ZX-81 and the Power Base which has versions for both the ZX-81 and Spectrum.

The Wobble Stopper is in three versions - small, tilted and large, for use with the Sinclair printers. Tilted versions are available in small and large sizes. All versions have a white nylon screw at the back which is tightened to prevent the wobble, clamping the RAM pack firmly to the ZX-81.

The Power Base is a sloping stand of about 15 degrees which has two rocker switches mounted on the sides. The right-hand side switch controls the power to the computer and can be used as a RESET switch. The power plug from the power pack is plugged into the back of the stand and the computer obtains its power from a lead which is terminated inside the stand. The other switch controls the two MIC and EAR leads.

The cassette leads are intercepted and plugged into the stand from the computer; two 12in. long cassette leads are then plugged into the tape recorder from the stand. The front of the Power Base has a turned-up edge to hold the computer firmly. The only screws are for getting into the base and to hold the rocker switches and power socket to the case. They are also supplied with rubber feet.
