HiRes package for Toddy Forth
Hi people! Here is a basic high-resolution graphics package to use with Toddy Forth (I recommend versions >= 1.5 , not tested with the previous ones). The graphic screen has a resolution of 256x192 pixels, with the coordinate (0,0) located at the bottom left of the screen, and the coordinate (255,19...

Re: Some reading for Toddy Forth.
For everyone using Toddy Forth, is worth it to correct the differences and make Toddy Forth more conforming to Forth-79?
The changes to be made are simple and I would have no objection to making them. So I leave the decision to who actually uses the system.

Re: MSX - Amstrad - Enterprise emulating a Zeddy?
Hi, In 1987, a ZX81 emulator for MSX1 was launched in Brazil, developed by Rubens Pereira Silva Jr. and marketed by the company "KRON Publicações e Planejamento de Sistemas Ltda". Here you can download it: http://msxbytes.blogspot.com/2011/11/emulador-de-zx81.html and here the review of the Brazilia...

Re: Using MCoder2 in EightyOne
Take a look at this manual to see if you are following the correct procedure.

But remember, once Mcoder is loaded above RAMTOP, there is less than 12Kb left for your BASIC program.

Re: BR programs recovery
Here are the converted programs, the "Demolidor" must be run at 60Hz (NTSC), but in the EightyOne emulator the screen is shifted to the left. Both would run at 2Kb, but interestingly they were saved with the entire screen file, without compression, so you need more memory to load them. Demolidor.p M...

Re: Counting TStates
It is still manual calculation (and when you start seriously to count TStates you'll know the single instruction ones by heart ;)). Indeed, semi manual, you still have to calculate the total cycles in loops and conditional jumps, but it helps a lot to visualize the count of cycles and bytes of the ...
