Here we have a couple of System 80 roms that need no introduction IA roms.zip Thanks for letting me share Mr Instance Automatics

The first rom of the Silver Ghost set hadn't dumped correctly, so Louie redumped the Silver Ghost rom that was bad and now they're good. New set attached. Again. Huge thanks to both for the new roms. Silver Ghost Redump.zip

so here is the switch on! IMG_2784.MOV

OK so back to the board! been slowly putting it back together!, solder resist done and components mounted back, good ram from 1985 tested and good put in, luckily the 9980 cpu was good as that was a ami type that had been replaced by the previous repairer and was fine (as you now know the ram was not so good) board now looks like this ok not really looking much different on the topside! just all the broken topside tracks done! where the top pads had been pulled off have been left if there was no traces connected to them as the underside was fine to solder the chip in. the resistor pack changed along with the diodes near the battery and a few resistors and a decoupling capacitor next to one of the chips as it had the top of it damaged over the years and one 74ls138 ic underside Pleased with that! the wire coming through the battery hole has been left like that at the moment as have been waiting for the bigger size pcb eyelets (rivets) to arrive which I am still waiting for! but this will be tidied up soon!! the 22k resistor on closer inspection DOES look like it was put on the board from new as did have slightly green on the legs from battery rot! so apologies to whoever repaired this last time! I have put it back but drilled a hole slightly over so it is now away from touching any tracks, does the job!! and underside, C1 had been changed in the crystal oscillator section and a 0.1uf (100nf) capacitor had been put in, I have now changed it back to the correct 0.01uf (10nf) capacitor, also I had a bit of lacing string lying about so thought it a good idea to tie down the crystal as it does seem very vulnerable perched on top of 3 resistors! hopefully that will help protect it!

Graham what a gay name.
