Salutations ! Does anyone know if there is a Smalltalk programming environment for the Amiga? Thanks in advance for any replies. Dave Springgay

The only Smalltalk that I have seen for the Amiga is a version of Little
Smalltalk that was on early Fred Fish disks. I believe that was version 1.0
of Little Smalltalk and there is now a 2.0 version around. Neither implement
more than the basic Smalltalk language (no graphics or anything).

I'm working on a port of GNU Smalltalk 1.1 which follows the Smalltalk-80 standard quite closely. At the rate I'm going it won't be "finished" until mid-year. Unfortunately I'm temporarily stymied by lack of memory. I only have 3 Meg and this is "GNU" code (know what I mean?). This implementation, like little-st, has no graphics support but I'll have a go that too (probably a year away though). If anyone can do a port sooner thay are of course welcome to do so. I must warn that the code is quite ugly. The C code for the interpreter has been hand-optimised, so it relies extensively on side-effects (some of them compiler dependent). It's a bitch to debug.

You could also think about porting the GNU Smalltalk interpreter. It currently has no graphics developement environment, but does has some rudamentary hooks for X Windows. I'm not familliar enough with the insides of it to say how the arena is implemented, except that you ARE going to need a lot of ram. I think that goes without saying when it comes to Smalltalk. The GC algorithm is a stop and copy implementation I believe. I'm not sure if it is incremental or not. Various tricks, including generation GC could be used to let you determine that a page is garbage and free it up. One neat idea is to use the MMU on the 3000 to catch accesses to 'Old Space' and update them (a la Symbolics 3600) I would refer you to the 1984 ACM Symposium on Lisp and Functional Languages for lots of neat stuff. On another tack: We need a way to share the MMU!!! -- :!mcr!: | The postmaster never | - Pay attention only Michael Richardson | resolves twice. | to _MY_ opinions. - HOME: mcr@sandelman.ocunix.on.ca + Small Ottawa nodes contact me Bell: (613) 237-5629 + about joining ocunix.on.ca!
