  1. would the infogrames guys take it on? they own atari at the mo
  2. see if any chips get hot - the 2x RAM chips at bottom-left try powering it up without the keyboard (or by holding select), this should make missile command kick in
  3. for 400 SVideo output, i replace the dangly RF lead with a dangly 5-pin DIN socket to make it compatible with the other A8 models here is the legend:
  4. might be worth testing the resistance of the trimpot in case it has failed
  5. youll have to design an arduino nano with speaker and a light sensor to trigger a flush noise!
  6. if youre anything like me, youll find it when youve given up and are looking for something else! 🙃
  7. hmm, displaying random characters could imply ANTIC is worth a check. it could be feeding duff data to the GTIA
  8. Yes, i got mine directly. very reasonably priced and good service
  9. you should be aware the XEGs has a diff'rent MMU - i dont know if it will work in a non XEGS machine
  10. yes you will need an SIO plug (or other rudimentry pinned connection) for the other end of the USB cable and a PL23XX driver in aspeqt set the cable as D1, real drive as D2 and boot a copy2000 or copymate type of program on your A8. then swap D1 in the emulator for your chosen ATR and put a blank floppy in D2 and set it off 🙃
  11. 'undred quid? not bad 🙃
  12. coo... youtube link doesnt say how much dough though!
  13. one of these will do it: expensive cable works great with aspeqt for this very purpose legend: USB green to orange SIO (pin 3) USB white to green SIO (pin 5) USB black to black SIO (pin6)
  14. Hi, thanks, its still a little janky! i read somewhere that the blanking signal for SCART RGB enabling is taken from pin9 of the PAL encoder. so i decided i should fit a more suitable monitor port that has sufficient pins for this and audio too. then i can re-try using the SCART connection instead of the RGBtoHDMI device. the green signal is the one thats amiss. when the parts arrive for the above, i will desolder the PAL encoder and fit a socket. if there is still no joy then i will get the oscilloscope out!
