Commodore 64 running BBC BASIC
Aztec Software produced a version of BBC BASIC for the Commodore 64 in the 1980s. It was written by Julian Gardner who wrote their Turbo Basic and Turbo Basic Compiler.
The released software seems very much an unfinished development demo.

This project is to port the full 6502 BBC BASIC interpreter to the Commodore 64. It does this by using a slightly patched version of the standard HiBASIC version of BBC BASIC II with an interface veneer to the Commodore 64 Kernal.

Development notes



Aztec Software Shado

Commodore 64 running Shado BASIC
Shado.prg  30K Shado BBC BASIC emulator.
Aztec Software produced a version of BBC BASIC for the Commodore 64 in the 1980s. It was written by Julian Gardner who wrote their Turbo Basic and Turbo Basic Compiler.
The released software seems very much an unfinished development demo, and was described as such in a review in Commodore User magazine. It describes itself as a BBC BASIC emulator, whereas the correct terminology would be a BBC BASIC interpreter. However, examining the code seems to show that what it does is pass code with BBC BASIC syntax to the C64 BASIC, so emulator could well be an accurate description. Additionally, the filename shado seems to suggest it just shadows the on-board BASIC.
