Some of the BBC Micro games I've played with cover-art, instructions and screenshots.
Replay data sheets
Quote from Vine Micros paperwork
The REPLAY system is a totally new development for the BBC Microcomputer, being a highly sophisticated but easy to use disc utility. It will take any* program in memory and transfer it to disc at virtually any point in time. This unique ability allows a program to be transfered from tape to disc, from disc to disc (in most cases), and can freeze a game or adventure during play for subsequent replay.
