HI, Ok sanello ! New test release: -Display "$BLACKJAK$" if you score=21. -You can set a 16 deck of card. -Card display in a machine code routine. BLACKJACKZ8021.P I hardly recognize this anymore, but there are only 2 issues I see so far. I think at 4910 is where you put the line to go reshuffle. I...

It does the same on the last release too. it will always toggle off dice already toggled when you press 6. If I want to toggle say 5 dice I press 6 to select all then press the one I don't want rather than pressing 5 separate dice. You can do exactly that with my suggestion too. On the "Final" rele...

A 20Mhz ZX81 was made by Andy Rea as a one off experiment, sadly having spoken to Andy he, like Sir Morris, is not likely to be back any time soon but just for reference there is a thread about the device. It included things such as.... QUOTE "20Mhz Z80 128K static ram ( split into 8K pages ) the f...

As there is no video circuit in the ZX81, the video is made in software. This requires tight timing to generate the right composite signal. With faster CPU, the ROM routine to create the video signal has to be updated. Even though this will work for some software, many programs have their own routi...

All should be on with all. If we want toggle, let's put toggle. See why in my scenario. The scenario that every person I have showed this to in my personal sphere takes issue with. I actually had an all choice originally but took it off since the original was so slow.

I was playing the "Final" release when I rolled 5 2 3 1 4, so I thought I'd go for a large straight. I started choosing the 2 then the 3 when I suddenly realized I already had a large straight! Hurray for me! So, naturally I chose to press 6 for all and then pressed enter. To my chagrin, the 2 and 3...

Real Zilog CMOS Z80 chips are only officially rated at 20MHz. Higher speeds are only officially available with code compatible processors (not pin or hardware compatible). Not sure what you mean by better voltage regulation, the 7805 can easily be replaced with a modern DC/DC converter / switching ...

In this case, nothing is display. "D" was locked.

Better set:

Code: Select all

   719 IF W=<B+BC THEN PRINT AT 10,13;" HIT OR STAY? H/S"

Should just be <

As far as winning with 5 cards, that is the 5 Card Monte Rule that you'll see in many of these blackjack games because of space limitations mostly. 5 cards without busting wins. It was a rule in a lot of friendly games before computers too.

Taking advantage of my lack of machine code knowledge doesn't seem fair. All means all though.
