Could we build an add-on co processor card for the MTX that gave a high resolution display? Then I could connect three monitors to it (one for the existing VDP, one for the 80 column output of the Rememorizer and a third for the new card)? Then I could have some fun writing a set of memory mapped g...

Mine arrived today. Big thanks to Lez for giving us these components - and to Dave for collating, wrapping and sending them on. Agreed :D My magic box of bits also arrived today :D 8-) Thank you very much to Lez and to Dave http://stardot.org.uk/forums/images/smilies/eusa_clap.gif http://stardot.or...

Oh, Dave, the Zilog Z84Cxxx parts are CMOS. You have put NMOS next to them. Making nice lists with easy to click to data sheets, supplies of gubbins, I'm gonna have to keep playing with, sorry learning PCB routing software rather than playing, sorry modifying a Joystick (will post details soon).

Funny reading the page you linked to. Before my mind drifted (and I thought, time to check the MTX forum) I was just comparing the ROM socket pin-out on a QL motherboard to see how easy it would be to "shoehorn" a 128k SRAM chip in it instead of a ROM chip :mrgreen: And what is the 6th ite...

I have a limited number of brand new electrolytic capacitors suitable for the power supply section of the MTX main board that I will be bringing. I will fit them on site (assuming Andy can provide suitable arrangements). Why are these important? Well, if these power supply capacitors are losing perf...

Why do I ask? Well, on a forum for another computer, there was a discussion on if a virus could exist, replicate and spread on a 8 bit computer system that has floppy disk drives. Some made the case that the computer that was being talked about could not support a true virus, as the OS, BASIC and DO...

He has just advised me that he has some spare CPUs MC68008P10s, MC68008FN10 68000 CPUs.. DIP48, and PLCC52 respectfully Also W65C02 DIP40 and PLCC44 6502s And asked whether anyone in the group has a use for them? Hi Dave :-) Thanks for the update :-) I have a QL PCB that may be in need of a 48 pin ...

I do have a reasonable size piece of black anti-static foam, but it is currently full of chips :lol: However, you can still buy anti-static foam, and even if I find some boxes with anti-static foam, by the time I have posted them to you, it would not be much cheaper than if you bought some new :roll...

Has any one come across any malicious code for MTX computers, e.g. a virus?
