What early computers had an excellent programming language? I know for many of them, the interpreted language was used as much or more for an operating system as language.
Definition of terms
- early computer: prior to dominance of IBM pc and Mac, but including late alternatives such as Commodore 128
- had: available at bootup, either motherboard ROM or ROMpac (not loaded from disk or tape)
- excellent: directly supports most capabilities of the machine, including graphics and sound, without needing peeks and pokes
- language: I know BASIC was extremely dominant, but some computers booted into something else, like Jupiter's Forth. (I don't know if that Forth would qualify as excellent, though.)
I am aware of several.
- the TRS-80 Color Computer could be bought with Extended Color BASIC
- the TI 99/4a had an Extended BASIC cartridge. Even their native BASIC had some support for sound and non-sprite graphics -- it had to, because neither Peek nor Poke was provided.
- the Commodore 128 provided an advanced BASIC when in c-128 mode
- the BBC Micro had BBC Basic as standard
