The hidden program on a blank tape...
No, really! Well, sort of. For anyone who's heard of 8-Bit Show And Tell (it's not The 8-Bit Guy, and they're not even in the same country), he was tipped off that there was a blank Computer Cassette available in 1982 that had a program printed inside the J-card for the computers of the day. The rum...

Re: Pool or Snooker on ZX81???
Seeing as I've just found this thread, two months late... how hard can it be, as long as you understand the calculations needed for a simple Spectrum snooker game, such as the one Visions made that fit into the 16K model? About the only problem I can see is that all the "balls" will be limited to wh...

Re: JSzeddy Down?
That was considerably less painful that I'd feared it might be. Well mown! You've earned yourself a black-and-white corned beef sandwich.

Re: JSzeddy Down?
While we're here - and that it's good to know JSZeddy is alive and well and very useful for assembling machine code - one thing still bugs me. Using its LOAD/SAVE feature, where does the virtual cassette file end up? The manual says... Programs may be LOADed from and SAVEd to a virtual cassette as "...

Re: CONT or CONTINUE in BASIC programs
If anyone's still interested, this is something I asked towards the end of last year's CSSCGC, and Andy Jenkinson came up with the goods. High/Low Continue showed how CONTINUE, in combination with poking a couple of system variables, can be used to jump to a specific statement in a multi-statement l...

Re: Converting tapes to P/O/TZX (reliably)?
Thing is, the bit patterns are so much more obvious on the ZX81/80 than on the Spectrum, that it's a wonder that any converter doesn't work first time, every time. If we think of a 0 as being represented by "V" and a 1 by "W" - because that's what it looks a bit like on screen, then the hex value 9A...

Converting tapes to P/O/TZX (reliably)?
Spectrum40 saw me wave some cash in Simon Ulyett's face at the Cronosoft stand. Two of my purchases were, technically, for the Spectrum's grandad. I don't own a ZX80, but I do have a ZX81, and both ZX80 Pacman and ZX80 Kong have versions that will run on the "ZX80 with 8K ROM", i.e. the ZX81. The ta...

Re: Happy 40th Birthday Spectrum
Happy birthday, Spectrum, and cheers for being there for me even when I didn't realise I needed it. I would say "allow me to spin a yarn with only the mildest of apologies for those who have heard it all before, or who might read it on any other Sinclair-related forum"... but I re-read it and it loo...

The first ever Lambda entries for the CSSCGC...
Since I've been relieved of the duties of hosting the comp.sys.sinclair Crap Games Competition, I've returned to writing games for it instead of reviewing them. And I'd been planning to do something for the Lambda, just in case that game I was half-promised last year never came to fruition. It may s...

Re: Lambda 8300 / Power 3000 System Variables
...I just found that and was doing some tests while you were writing that post. Looking through the German articles, though, it doesn't look like it's a simple case of "take the address of the display file where the character is, subtract 2000h, and POKE the right value" because each display file li...
