APL - MCM70 from the Micro-Computer Machines. For the mid-70s this was a truly amazing machine. - Dimensions were about 6"x14"x24" - microcoded APL implementation - dual casette tape drives for mass storage - single line 20(?) character display - full APL implementation MCM released several hardware based APL machines in the mid-70s. It can be argued that a microprogrammed language implementation is not direct hardware execution, but close enough for me. list of microprogrammable architectures: B1700 Microdata 3200 Interdata 8/32 Nanodata QM-1 CDC 5600 Digital Scientific META4 Varian 73 Intel 3000 HP21MX The above list is from "Microprogrammable Computer Architectures" by Salisbury (1976). The IBM 5100 ran APL and BASIC, but I know it did not implement APL in microcode, don't know about BASIC. "Computers in the 1980s" by Turn (1974) also has a brief, but interesting, take on HLL hardware. Has the SYMBOL machine machine been mentioned?

Re: Scott writes: BTW, that should be Burroughs B 5000 (don't forget the "B ", and the B 5000 preceded the B 5500), and the other models: B 6500, B 6700, B 6800, B 7500 (?), B 7700, and ?. Also, the B 1700 (ALGOL-like language was used to write picocode (yes, pico)) (other models: B 1800, B 1900) However, as others have pointed out, many of those machines didn't directly execute high level languages. But, the Burroughs are important in the HLL area: - may have been the first designed for HLL specifically; - (B 6500 and later) had no assembler. Think about it...the only language available to the operating system implementors was ALGOL (ok, ESPOL, which was Burroughs ALGOL with some more extensions). And, re: When you look at P-code, you say: Ken Bowles sure knew the Burroughs B 6500! P-code is extremely closely modelled after the CISC stack-oriented instruction set of the B 6500. (Dr. Bowles, head of the UCSD computer center (which had a B 6500) was in charge of the UCSD Pascal project.)
