Source 1981 16K
39K The original BBC BASIC developed on the Atom/System 5 and supplied with early versions of the BBC Microcomputer in 1981.
Source assemblable with ARM BASIC 65 to target either the Atom/System or the BBC.

16K
16K US BASIC 3. This is probably not quite HiBasic3 assembled at &8000, as a binary diff shows more than just addresses relocated. As well as COLOUR and COLOR being transposed, a lot of the ROM from &9A00 onwards is slightly different.
HiBasic 3 BBC Tube 1983 16K BASIC 3 relocated to &B800 to run on the 6502 second processor.
Basic 4
Basic4.zip Master
Source 1984 16K
31K BASIC 4 as supplied with the Master 128. BASIC 4 will run on the BBC B/B+ or Electron if the 6502 CPU is replaced with a 65C02. Naturally, any MOS- or filing system-specific functions (eg TIME$) will not do anything unless additional software responds to the calls.
Source assemblable with Assem or ARM BASIC 65.
HiBasic 4.01 Master Tube 1984 16K BASIC 4 relocated to &B800 to run on the 6502 second processor, with a two-byte DIM bugfix.
Basic 128 Master 1985 15K BASIC 4 set up to run from main RAM with shadow screen and four banks of sideways RAM for 64K of program workspace. Version 1.10.
