hi
i have an upright midway space invaders. when i got it the monitor was painting just white, no sprites atall but the game coined up and played as normal. after trying to work out what was wrong by a process of elimination i worked out it was the chassis, which was a motorola m5000 (from memory)
i sourced a second hand chassis a 19VP111A also a wells gardener i think? from a guy in the states, he modified the yoke(added another wire to attach to the CRT) so i could use it with my CRT which is a 19VARP4. this chassis worked, however the sprites seemed to get larger to the right of the screen.
i sourced another chassis, this time a WG 22V1003. the person i got this from is a technician also in the USA (i am in australia) and he told me that this chassis was working pretty well. out of the three chassis i have it appears to be in the best condition, the 19VP111A is also in good condition, the motorola is pretty dirty and the worst of the three.
my question is, which of these three chassis would be best for my spacies? i sorta would like to keep it original with the motorola chassis, but i think this would be the hardest to repair. would the 22V1003 work with my CRT? i am yet to try this.
what do you guys think, and what would you do in my position. which is the best chassis? which is the most reliable?
any advice much appreciated.
the 19vp111a actually turned out to be a motorola xm-501
