I seem to rememebr the cassette-based editor/assembler I had for the
TRS-80 Model 1 was like that. I am not even sure it supported ASCII
characters as constants, you may have had to enter everything in Hex

I think (although I don't have it), the assembler for the Philips P850
was like that (you had to put the second word of 2-word instructions as a
constant). The assemblers for the other P800 series machines (which had a
lot more memory) did it more as you'd expect.
