Coral Lisp was the ancestor of MCL/OpenMCL, and used to fit in a couple of megabytes. But it had pretty strong integration with the mac. You might want something like Cambridge Lisp (ran on the amiga as a text-only app) instead. Or any of the lisps of that era that ran on more-or-less stock 16-bit hardware. It sounds as if you probably have the resources to cross-compile if it turns out to be useful.

Motorola 68000 is a 32 bit processor. Thanks for the 'Coral' and 'Cambridge' hints, googling them is looking interesting. -- Reply-To email is ignored. -- Posted via a free Usenet account from http://www.teranews.com

GUI overhead probably wouldn't be that bad, it would be sensible to separate the GUI and lisp afterall. One of the things I do know about early macs is that they did have a command-line if you knew the tricks. I also vaguely remember some sort of lisp in those early beasts. I agree that getting something non-Mac but 68000 would be best, I just don't know where ancient software might be hidden nowdays. I though about the TI-85 too, since I was a pretty good CP/M and ZCPR3 hacker (some archives still have my 'make' for ZCPR3). Thanks for the GC pointer there, the ebay price difference between these two models doesn't seem enough to go back to 8 bits. There is a CP/M lisp somewhat 'freely' available BTW and faking enough of the CP/M API to get by is not that difficult. -- Reply-To email is ignored. -- Posted via a free Usenet account from http://www.teranews.com
