I seem to have the same problem. My television screen goes white and I have to turn the computer off and back on. It seems to happen more when I have bigger programs in memory, for example a 4K Basic putt-putt game or a 2K determinant program. Does anyone know what causes this? Can I correct this with a bigger power supply, or should I use a more (physically) stable connector for the memory? Will permanently attaching the ram pack to the computer via some sort of clamp help any? Waiting for any and all ZX81 ideas, David Elliott
