Re: Campus LISP on a ZX80

I just built a similar version for the Lambda. You can find my comments about the 16K release of the Campus LIsP there: https://www.sinclairzxworld.com/viewtopic.php?p=52289#p52289 zx80_lisp.png (I forced the error message to show the translation of the "QUOTE" symbol, on the ZX80 it is obtained by ...

Re: Campus LISP

The standard version has more stack space, allowing bigger programs or in general giving the interpreter less reasons to crash than the one providing graphics It's better to elaborate on what this CLiSP is and what it is not. First of all, the Campus LIsP is a limited subset of the LISP language. Th...

Campus LISP

Yesterday I shared a very minimalistic version for the 16K RAM ZX80.
I thought it could be of some interest also for the LAMBDA 8300 owners.

note this is still highly experimental, in example PROGN() does not work correctly

ELIZA

Yesterday I built this program for the ZX80.
I realize there is a bit of interest on the chatbots recently, so here's a version of this piece of history for the LAMBDA 8300


EDIT: I this post should probably stay in the software section, sorry for the confusion

Re: Software Preservation

I think I understand the reason for using tzx, it allows the creation of very accurate tape images and allows to pack many program blocks in a single file. Probably excessive accuracy is even uncomfortable (I'm thinking at the leading noise in a tape), but it is still possible to extract a P file fr...

Re: Werewolf chase for zx80

I like those radical simplifications of the algorithms. When they are cleverly chosen the game is still enjoyable and you save lots of space. Now it's on you whether to make it an essential/minimalistic game or add stuff like graphics, sound colour, etc. My favourite game is Mazogs, also because I c...

Re: ZX80 ELIZA

Same for the zx81, in theory.
Besides the possible BASIC limits did the zx80 have more he limitations than a zx81?

Re: ZX80 ELIZA

I just succeded in porting a very minimal version of the LISP interpreter on the ZX80. I was disappointed in finding so many bugs in z88dk, all of which I'm responsible for ! I suppose that, since this first port is mostly working, making it use 32K could have space enough for ELIZA to be put on it....
