The Ramlok Kit is designed to stop a ramlock from wobbling and causing program loss, a well known problem to Sinclair users. The main problem is that the edge connector does not provide an effective mechanical fixing to the back of the computer. Also, the surface of the male connector at the edge of the computer is made of unreliable tinplate. This is what the kit aims to cut out. It consists of a connector and a mounting bracket.

The ramlok is fitted by removing the bottom of the computer, then pacing the connector over and in line with the existing edge connector and soldering the underside connections. Then the circuit board is unscrewed and the upperside connections soldered. The board and bottom of the computer is then replaced. Next, the mounting bracket is placed on the computer, then aligned with rampack and stuck on. Two different spacers are provided to account for all types of rampack. The rampack can be removed by pulling out a split pin in the mounting bracket. It can also be used on the ZX80 but due to different construction it is fitted differently.

I have found in use that the it does provide successful non-wobble connectors, although fixing on can be a bit tricky to people unknown to electronic assembly work. A spacer kit is also needed if to be used with a printer.

The kits costs £7.50 plus 50p P&P from Adapt Electronic, 20 Starling Close, Buckhurst Hill, Essex IG9 5TN.
