Any idea which Ada it was? There were two that I know of, the Stupidsoft (sorry, old habits: Supersoft) Ada, and our Janus/Ada. Looking at the messages, you probably had the bad guys. :-) It was quite a trick to compile a useful subset of Ada on a 56K machine. OTOH, targetting that machine is not particularly difficult. For Ada 83, the Janus/Ada runtime never exceeded 12K on the 16-bit machines, Z-80 code was quite a bit more compact and also much more aminable to compression. So, I don't think that there would be any particular difficulty targetting Janus/Ada 95 to such a machine (with compiler running on Windows or Linux). You probably couldn't use every possible Ada feature in programs targetting such a machine, but the sorts of programs developed for such memory-limited systems don't do that anyway. If anyone is interested in such a target, I'd be happy to try to figure out how to read the 8" CP/M floppies that contain the source code to those versions. (Our last CP/M machine doesn't boot anymore, couldn't figure out why.) Randy Brukardt R.R. Software, Inc.
