Thanks Nyef.

As Datatronic VICFORTH was mentioned below is a link to that one. I've updated the zip with a new version of the MS-DOS screen editor (old one didn't work under DOSBOX for some reason). Also included is a disassembly. There appears to be some free space in the ROM image potentially allowing a bug-fix for the U* U/ functions which plagued this and other early 6502 Fig-forth implementations.

I just searched for "VIC-20 HES" on eBay and saw a listing for $10 or so that had a bunch of carts. In the lot, was a red labeled HES Forth cart. Might be worth bidding on.



I clean mine with single malt Scotch while I'm drinking Isopropyl alcohol.

Oh crap...I think I've been doing that backwards!



Best place to ask would be over at the Denial forums. If you want to send the file to me, I will start a topic over there and ask where to archive it. I don't think there were many Forth's made for the VIC-20 so it would be nice to have.

Thanks for doing that!

A zip containing HES VICFORTH dump, manual scan and disassembly is here:

Thanks to everyone involved!

When I try to decompress it, it says not an archive.

How was it packaged up?

It seems to download and extract just fine on my beat-up old Windoze Vi$ta machine.

Well, it's probably because I can't visit that download site from where I'm at. So I did it on my phone and sent the file over to DropBox. Then copied from DropBox to my PC. So I guess it got messed up in the translations.

I will try again later when I'm on a real computer.

WinRAR in ZIP mode. D/loaded & it extracted ok with WinRAR and Win10 explorer.

I use 7zip which works with RAR files. I think the problem was my phone. When I am at home later, on my real computer, I will download it then.

FYI, I uploaded the ROM here:

I also tested it in Vice. Seemed to work but my Forth skills are very rusty.

Thanks!

I encountered an issue that puzzling. After loading a screen previously saved to a file (cassette or disk) it would be followed
by a string of junk graphic characters and an error msg. I managed to avoid the spurious junk and error msg by executing
the following after booting up HES VICFORTH:

FIRST LIMIT OVER - ERASE

This zeroes the disk buffers in RAM including the important 4 extra bytes that follow each buffer. Those 4 bytes not being
zero is what caused the junk/error message.

What's puzzling is that I should need to this at all. I'm using VICE. Maybe a real VIC with HES cartridge works differently?

Ok so I found out the same can be achieved using WIPE.

1 EDIT WIPE

will initialize the buffer after which the LOADS command can be used to retrieve the screen from the file without the
junk & error message.

FYI,

You can find the manual here:

An ascii text OCR of the manual will be available shortly. I need to clean up a few errors.

It's now ready. I omitted scans of the fig-Forth manual included in the PDF (not sure it was
originally provided and can be obtained separately in any case).

Reading the manual I was reminded of an easier way. Just place ;S after the last item on the
screen that you want interpreted. ;S immediately stops forth from interpreting the remainder
of the screen - thereby avoiding the problematic trailing null bytes.
