I guess I'm an old fart. I like architchures that program in a cool way.


	IBM 360	The instruction set is so rich that except for type
		conversions and I/O you could translate COBOL 1 for 1.
		Which was what the machine was designed for.

	Buroughs cica 1968-1970 Operating system was written in ALGOL.

	HP 3000 circa 1974? Operating system written in PL/I or ALGOL
		(can't remember).

Halfway there: CDC 6x00. Good assembly language, except that it had that
		silly 60 bit word.

		Apple II. 6502 wasn't bad, but the different roms for
			  different slots sucked.

		Macintosh. 68000 was much better processor, but hardware
			   was limited, originaly only Pascal available.

Unexamples (flame proof suit on): anything little endian. I could never
understand why except that "IBM did it the other way".

Commodore 64. Assembly language sucked. Too many forward references produced
good object code in the listing, bad code in the executeable. Return codes
not documented. Example 1 = file not found, 2 = i.o error, anything else,
either success or one we missed. :-(

Best current one: The AMD low power chip that is destined to fail. It has
a MIPS core, with the power draw of an ARM. Too bad no one has any software
for it. If you wanted to start a company and build a device around it they
would probably give you a million or two chips to play with.
