[] If you could mail me the following info on implementations of SCHEME you know of, use, maintain or distribute, I (and a few other people) would be most grateful. What machine(s) does it run on? How portable is it? How fast is it? (subjective impressions will do fine). How much memory does it require (per user)? How can I get a copy, and for how much? What sort of garbage collector(s) does it use? Other info will be welcome, but the above is what I'm mainly interested in. I intend comparing it with our current implementation of ML, which (to the best of my knowledge): Runs on VAX/unix, VAX/VMS, Pyramids, Goulds, Suns, Orions, BBCs with the 32016 processor, IBM/unix, at least. Uses an abstract machine written in C, so is very portable (I think it requires a 32-bit word machine though). Is faster than compiled franz on a VAX (possibly depending on how the franz is configured). Usually uses 1M data space with a copying garbage collector; a compacting collector can be used with half the space, & the precise amount can be adjusted anyway. Can be obtained by tape from our department for #50 (non-profit use only). We don't support it. If you want more info, please send me mail. -- Dave Berry.
