Re: ZXForth. Plagerism,clever marketing or something else?

Post by kpalser »

I sent some comms to both Bob and David back in May this year to ask if I may include the Forth ROM in my iOS/iPadOS ZX81 app. I did not get a response from either. With Bob I tried messaging his LinkedIn and a gmail account that I found (I didn't try his work email address as I thought that would be crossing a line after trying the first two). With David I tried to contact him via a business that I knew they (David and his partner Victoria) had used. I think David moved with his partner to South Africa.

I recall seeing Bob released the source code to the ROM in the 1990s and I suspect Bob has received comms but has moved on and doesn't want to dwell in the past. I hope I'm wrong.

If any of you do make contact, then I'd be grateful if you could mention my desire to include the ROM.

On the plus side, my email to Bob didn't bounce. OTOH, I've not heard back, either.

All of this prompted me to update my entry on Pluri-Forth (marketed as Tree-Forth by Soft Magic):

Bob did release the source code back around 1990, though it's not clear where:

Some good reading there Jdfan. The first link in your list I posted on the German forum three years ago as they do a lot of Forth work and it sparked some discussion but more importantly revealed the maths bug in the UK version which Bokje of the German forum fixed then issued a corrected version. This corrected version is the one that should be used in either emulation or EPROM.
As far as I'm aware the emulator Eighty One still uses the bugged version even though the error was pointed out at the time,obviously will stand correction on this

link to the German forum thread.

Also attached is the corrected ROM image should anyone have a use for it.
