Before Abed joined the CATUG, we ran an article on how the Motorola Sinclair Users group kept their ZX80 and ZX81 machines going with no crashes while others in the U.S. were experiencing crashes. We tried to tell the others through newsletters but couldn’t get into print. We took advantage of the situation by buying up the machines of disgruntled owners and applied high viscosity mineral oil to the connectors between the ZX machine and its RAM pack, the very same thing we at Motorola used on the connectors of our television and communication equipment. The result was no more crashes!
When using high viscosity mineral oil on your equipment, make sure you get it only on the P.C. board and connector, not anywhere near the rubber bubble pad of your keyboard as it will ruin it, causing any rubber to swell and become distorted!
Where do you obtain high viscosity mineral oil? From your Drug store, it can be found with the other laxatives!
