Sinclair ZX80 / ZX81 / Z88 Forums

Well, I certainly didn't want to open a can of worms. I was unaware of the controversy regarding this site.
The powers that be can delete the thread, or can I delete a post myself?

Sorry

That look great, I'm envious!!! It's nice to know that programs can still be tested on the real thing. I have a ZX81 and T/S1000 with RAM pack, just no cables, power supply or B&W CRT TV.

Been there done that back in '87. The program is available on Fred's site http://www.pictureviewerpro.com/hosting/zx81/fredn.htm as well as here... http://www.theoldcomputer.com/roms/index.php?folder=Sinclair/ZX81/Various However, it doesn't work very well in emulators for reasons Fred explains.

Give it a try, make some of your own definitions. Sample definitions are contained in the Parameters.txt file.

An umpteenth version of Data, Read and Restore commands for ZX Basic. If nothing else, it's interesting in that it's a good example of manipulating string variables from within the machine code program.

Hi Siggi; Yes, that would be me, those were fun times. Sad to hear about Fred's passing. I only go interested in the ZX81 again a couple months back, so I'm relearning everything. I was surprised to see much of my old stuff available on line, who would've though. Sadly, all my old hardware software ...

Here's a type-in I did from Your Computer 8305. It's a nice Basic Listing program. It comes in very handy when comparing a printed listing from a magazine to what you've typed in, to see if they match. The only problem is line numbers for 0 to 999 aren't padded with spaces, so there's not an exact m...

Hi All; Don't know if this is redundant but I found this at http://www1.cs.columbia.edu/~sedwards/classes/2006/w4115-fall/reports/zx81basic.pdf Looks like some kind of project to write a Java interpreter for ZX81 Basic. By eliminating Arrays and "slicing" he omits one of the most powerful features o...
