Re: Puzzle 15 solver ?

Hi Bill Thanks, great work, i will take a look at the code, I already tried it it works quite good, and not to slow even in Basic. If you allow me I will continue the project for a Finished game later :) I have been thinking about that for some time, and actually started the project using Intellivis...

Re: Puzzle 15 solver ?

Hi Bill. Thanks for you input, yes its a "human" way to solve it, I think it can be solved, I see alot of other solvers out at the internet written in Phyton and C but I dont know those languages but as I understand they use some kind of recursive functions which is not great for a stack-based 8-bit...

Puzzle 15 solver ?

Hi. For quite some time I have been thinking to make a Puzzle 15 game, both for Memotech but also for other systems, I recall in the 80s I did, Not sure if I ever got the Memotech to work, but for sure I did a Spectravideo 328 version. Back then I did not think about how to solve it, and I even now ...

Re: Autofire Joystick project.

Mark, i tried another circuit today. 555 timer.png It worked great, I made a test program (in basic), it seems like i can manual shoot around 15-20 shoots per second. The relay seems to give up around 15 shoots per second. Maybe a solid state relay is faster, i used the click one. acutally my test p...

Re: Autofire Joystick project.

Hi Mark. Thanks for the input. But if there was a chip somthing like a relay, which could be driven by the 555, so it could open and close just like a manual push button do it would be perfect I was told a NPN could do that, but its not the case. Maybe it works for C64, Amiga etc. But not for MTX. S...

Autofire Joystick project.

Hi. I wanted to build an autofire for the MTX. I tried to use the 555 timer ic. But it seems like the 555 timer do not put out a very square output, and that fools the MTX to think when its not firering, other inputs come to the joystick. Some people suggested to add a npn transistor, at the output....

Re: Eye-watering ebay prices

I dont have that much hardware, I think i might have 5-6 computer that works, but no diskdrives, I have a dead SDX (FDX) box, a 80crt card, diskcontrollercard, and also a Silicone Card. But the box is not working, it need service, no time, so for now it have to be a future project. I think Dave have...

Personally, I think it's at the top end in terms of total package,...

Re: Another dead Memotech - Can it be saved ?

I did a bit more testing, it seems like the Z80 and the VDP was dead, i checked the parts in another memotech. But the CTC. The VDP got very hot very fast, so I guess it was shorted. The pal board kind of work but gives gray scale picture, sometimes i get colors, but weird bars and sometimes some re...
