Re: Remake of an ancient board game

On the ZX81 version seismic survey has to done first before the concession sales appear as there is no point doing a survey on land you already own, it is supposed to give an idea of what might be in an area any oil etc so when a concession nearby comes up it is worth buying.

Re: Remake of an ancient board game

Seismic survey still not working and this is supposed to be the first thing you do and you have to do a few before concession sales appear. Screen becomes very messy with duplicated headings, CASH, LOAN, BALANCE SHEET etc not being cleared (see picture) After a while also the top row of co-ordinates...

Re: Remake of an ancient board game

Hi Stefano. Just a few points (played on real ZX81) 1) The cash amounts are not lined up correctly on the right of the screen. 2) The line "insufficient funds" never gets cleared from the screen. 3) The seismic survey is the first thing that is used in this game yet it just keeps throwing up "Not av...

Re: ZX81 Toddy Forth-79

It has been a pleasure to test this most excellent Forth79 for the ZX81 and thanks to Roganjosh too for his equally excellent version of Forth79 which I have had the pleasure of testing, we now have 2 versions of this languages dialect. Both have been approached from a different angle and have their...

Re: Lardo buys another zeddy

Nice Lardo. I have a soft spot for those Stonechip memory packs, more reliable than Clive's offerings in my opinion. They use a different memory chip to the Sinclairs(Mark will know which ones) and if you pop the back cover off (clip on on not screwed) there should be a set of clips that take a 16k ...

Re: Help on MIC-Output ZX81

Also as Mark has previously pointed out, the output from the 81 is so low that the amplification level required is very large. In my experience with audio work something like a good guitar pick with an output of 50-100 mv requires at least two stages of pre amplification for a decent usable signal o...
