About
A pair of utilities from Crystal Research Ltd of Torquay, advertised in 1986 at forty pounds plus VAT. Crystal wrote Xtal BASIC and Xtal DOS, so their utilities were aimed at people working close to the machine.
The advertisement is the only record of them we have, and it does not describe what they do beyond their names.
No Copy Is Known
Neither program is in this library or any collection we can check.
Can You Help?
If you have a Crystal Research disc of any kind, please get in touch. Even a catalogue or price list naming these two would tell us more than we know now.
