Re: SD extension on ZXpand+

Whilst I know zilch about these things I do know that the spand card slot is one that doesn't detect whether the write protect tab is set on the card and will write to it regardless of position so does it require an extension cable/slot that obeys the same rule?


Again forgive my stupidity

Re: What to do with an unusual ZX81?

My own personal view is there are more users than collectors out there, myself included. The kludged ones are still deficient ROM wise and any I have come across over the last forty odd years I have happily rejigged. Improve the bugger and let someone enjoy it as it was meant to be enjoyed without w...

Re: Snake Game - a game written in Forth

If like me you make a ton of mistakes when typing in listings then here is the finished product for those who wish just to try it out. I have changed the controls to 5-left 6-down 7-up 8-right as I find them easier than those in the listing. To use load Toddy F79 as normal then enter.. 1 GET SNAKE22...

Re: Snake Game - a game written in Forth

Excellent work, Kelly :ugeek:


Something that to the eye looks like BASIC with the speed and smoothness of M/C.

I shall be studying this and will try to work out how it works at the nuts and bolts level and hopefully improve my own feeble efforts. :oops: :lol:

Re: Strange integer behaviour

Here are two programs which show how the 8 digit limit can be circumvented using strings.

One simply prints PI to 8192 places (eventually) the other calculates then prints numbers to high powers, a fast emulator is useful here.

An examination of the code may be useful to you.

Re: Enhanced ARX True High Resolution Display Driver

I recall there was an UDG4ZXpand board (which I think Andy created also but correct me if I am wrong). I'm wondering if this will make the 8K-16K RAM provide by the ZXpand ARX compatible. Does anyone know? I have tried the demo on Andy's UDG4ZXpand board on an issue one ZX81 with an issue three ZXp...
