Commodore Computing International (GB)
Commodore Computing International was a British magazine dedicated to Commodore computers, published by Nick Hampshire Publications (Apr/May 1982 to Jun 1984) and Croftward Ltd (Jul/Aug 1984 onwards). It was a replacement for the newsletter Commodore Club News. Early issues were mostly technically-oriented including hardware projects, programming tutorials, and articles examining how computers are used in education and business. Later issues were more entertainment oriented with greater games coverage. Commodore and Amiga Horizons was incorporated into CCI from Vol 4 No 11 (Jun 1986) onwards. The editors were Pete Gerrard (Apr/May 1982 to Dec 1982), Nick Hampshire (Jan 1983 to Jun 1984), Sue Pearce (Jul/Aug 1984 to May 1986) and Antony Jacobson (Jun 1986 onwards).

If anyone wants to use these loaders to make a fresh copy of Tinymon, then the following commands must be entered before loading them: POKE 5139,0: POKE 43,20: POKE 44,20: NEW Controls: .R (display registers), .M (display memory), .G (goto address), .L (load), .S (save), .X (exit). |
