Re: ZX Basic vs Commodore V2.00 (Vic 20)

Hi Dr Beep,

I though the comparison was for ZX81 BASIC against VIC-20 BASIC. If not, then one may also define mathematical functions in ZX Spectrum BASIC, but more complex than those on BASIC v2.

Regards,

Re: ZX Basic vs Commodore V2.00 (Vic 20)

The biggest difference, of course, is that the ZX81 ROM is 8K whereas the BASIC Kernal on the Commodore VIC-20 is 16k, therefore Commodore BASIC was more verbose.

Shaun.

Re: ZX Basic vs Commodore V2.00 (Vic 20)

Commodore BASIC only allowed each line number to be a maximum of 255 tokenised bytes, but realistically four lines by 22 columns may be entered. This means 88 characters on entry per BASIC line, either in your programme listing or in direct mode; with keyword abbreviations, this would mean more than...

Re: 50 games with hires in 1K

Re: 50 games with hires in 1K

I've just found out about the ZXBlast - wondering what would happen if I plug this into my ZXMore? Are the two devices compatible?

Regards,

Shaun.

Most will have 16k or 32k. Hmm... and the ZXblast has 512k, so that should be sufficient:-)
512K ought to be enough for anyone.

Re: 50 games with hires in 1K

Clock face

I've refactored the clock face programme in the ZX81 manual to include a digital display, as below.

I've made it for the new ZX81x2 ROM. I'll refactor later.

That would be great - Dr Beep's Mini Arcade or something :-)

Re: 50 games with hires in 1K

Hi,

Just a thought, with shared sub-routines and such, would it be possible to fit all 50 games into a 48K expanded Zeddy somehow?

Regards,

Shaun.
