(I'm thinking of the 68008, etc. not their "big" brothers.) Has Ada ever been targeted to a machine where the largest registers are 16-bits? Such a compiler is possible, but it would be an effort. (Hmmm. Doesn't that describe the Western Digital compiler? The Russian compiler for the PDP-11 clone doesn't count, since the address register on most 11s has 22-bits.)" But you answered your own question earlier, the 8088 is such a chip (largest register is 16 bits), and yes, Ada was indeed targetted to the 8088 (and self hosted as well by Alsys, Meridian, RR, and Ada-Ed, all of which validated in this environment). However, most likely you mean a case where the addressing space is also limited to 2**16. But here we have answers as well. All the above compilers except Ada-Ed could target "smal" mode on an 8088 meeting this criterion, and also the Alsys Transputer compiler could compile for a 16-bit machine (there was a problem passing all the Text_IO tests due to space limitations, but otherwise it was a full language compiler). I think it would be entirely possible to target the 8-bit chips, given resources, but at this stage, I think this would be a case of looking too far backwards on the technology curve, and there would not be a market for such a product anyway, so the utility of such a product is likely to remain moot. Another example of 16-bit targetting is the small versions of the 1750-A, I expect there are others.
