You have some really interesting software on that page - can you please provide permission for me to include your software and details on my own website - http://www.rwapsoftware.co.uk/zx81/zx81_software.html
I will need to know which of the software has your own copyright, as I will not offer the copyright software (such as Quicksilva titles and magazine titles) for download unless their permission has been obtained, although I can of course list them and offer a link to your site

Hi Kmurta many thanks for this as I am really into forth can You confirm this is emulator only or can it be ported onto a real ZX81?kmurta wrote:I introduce here my last project, a DTC forth implementation to the ZX81. Enjoy!

Hi,
No way on Vb81 XuR !!! ( lol ... french Forth is better... )
Perhaps on the sZ81 emulator.(wrx+zonx)

Re: Toddy Forth - a new ZX81 forth implementation
Toddy Forth was developed with the purpose of creating programs for use on my TK85, adapted with characters board mapped at address 3000h and ZON-X compatible sound board. But it can be used in a standard ZX81 too, just disable the UDG's withMoggy wrote: Hi Kmurta many thanks for this as I am really into forth can You confirm this is emulator only or can it be ported onto a real ZX81?
Regards Moggy
Code: Select all
HEX 1E 461C C! COLD
Indeed, 4 programs supplied with Toddy Forth was compiled for use in a standard ZX81:
HANOI.P / BREAKOUT-STD.P / MANCALA.P / PLOT-TEST.P
The forth programs can be written in a plain text file (see examples at Progs directory) and loaded in Eightyone emulator to be compiled:
The display file is fixed in memory at address 4092h (first screen position) and the forth system variables are:
Code: Select all
43AB S0: Base value of the parameter stack
43AD R0: Base value of the return stack
43AF RSP: Return Stack Pointer
43B1 TIB: Terminal Input Buffer
43B3 LBP: Line Buffer Pointer
43B5 STATE: Contain the compilation state
43B7 BASE: Current number base, used for input and output conversion
43B9 HLD: Holds the address of the last character during numeric output conversion
43BB CUR_POS: Position of cursor on the screen
43BD DP: Dictionary Pointer
43BF CONTEXT: A pointer to the vocabulary within which dictionary searches will first begin
43C1 CURRENT: A pointer to the vocabulary where new definitions are created
43C3 LAST: Last word defined in CURRENT vocabulary
At last, a note about the programs saved with CSAVE: the Eightyone has a bug at LOAD patch so EO resets after load the program. To deal with it, are two options: 1- use the EO V0.43C that works fine with CSAVE or 2- add a zero byte at end of the p file, with a hex editor (I have chosen the second option).
It works for me in Vb81 XuR:XavSnap wrote:Hi,

Re: Toddy Forth - a new ZX81 forth implementation
Could you upload the version which works with the standard ZX81 onto your website as well - that would make it easier for everyone

Re: Toddy Forth - a new ZX81 forth implementation
I can see that I need to update the page on the forums listing all the programs which use hi-res graphics
Can you clarify which scheme your software adaptations support please - see the definitions at the start of that topic.
