Re: Moon Patrol

That would be great. Also if anyone can make the music that would really be nice.
I don't have a sound chip or I'd try it myself.

Re: Moon Patrol

Here is my initial design. I may change the ship at the top to graphic characters because it is kinda hard to see. The game play will be in assembly. And the source will be available. There will be parallax scrolling. The buggy wheels alternate from "XXX" to "+++" to give that rolling look. Any comm...

Moon Patrol

I was thinking about making "Moon Patrol" for the ZX81.
Was looking for already existing versions for inspiration, but I haven't been able to find any.
Does anyone know of any "Moon Patrol" type games for the ZX81 ?

Thanks,
Bean

Re: TS1500 composite mod

I use a ZXpand on my TS1500 by plugging the TS2040 printer in first. Works fine.

Re: Printing a floating point number

Here is the code. Use it like this: 0 REM machine code 10 FOR A=0 TO 10 STEP 0.1 20 PRINT USR 16514;A 25 PRINT 30 NEXT A When it prints a value it does not move the print position to the next line, even if you don't have a ";" at the end, hence the need for the seperate PRINT line. The value ("A" in...

Re: Printing a floating point number

I'm having a problem with my code. It is printing the fractional part TOO perfectly. For example: 999.9 gives 999.9 But 9999.9 gives 9999.900002 and 99999.9 gives 99999.899994 and 999999.9 gives 999999.899903 I think the value I give is the actual value that is stored in the 5 bytes, but that is not...

Re: Printing a floating point number

I am so glad that someone is working on this...Printing of values it terribly slow on the ZX81, and it makes the whole computer seem much slower than it really is. I am actually working right now on a program that needs to print floating point values quickly. It is a program that makes the screen be...

Re: Can a ZXpand be attached AFTER a TS2040 printer ?

Seems to work okay on a TS1500 plugged in after the TS2040 printer.

The only thing odd I've seen is that sometimes the BREAK key doesn't work, even in BASIC programs ??? Not sure what that is all about, but I'll investigate further when I have time.

Re: Can a ZXpand be attached AFTER a TS2040 printer ?

Well, I'll try it when I get the ZXpand and let everyone know.

I seem to remember that the TS2040 "slowed down" some of the signals, but I don't remember the details.

Can a ZXpand be attached AFTER a TS2040 printer ?

I have just ordered a ZXPand, and I would like to connect it to a TS1500. But the ZXPand will block the connections, so I thought I could put the printer (TS2040) on first and that would provide enough room for the connectors. So I was wondering if it matters either way if the ZXpand is before or af...
