I will give you all a brief history of this project.
Spotted it on ebay alongside a dragons lair 3 years ago, both had been converted to jamma the LL had final fight in it. I told a fellow collector who was after the dl and when he won the auction he let me have the LL (Cheers bods!).
I sourced replacement parts from Oll, Pman and Morty. Morty supplied me with the much needed complete control panel which was an archer repro, Pman the G05-801, Oll supplied me a battlezone brick which I had to modify for the lunar lander, the loom and AR1 I got from America.
After modding the power brick I checked the Ar1 which was pumping out 12v which is no good. I spotted that someone had replaced the LM-305 with a LM-105 so I replaced this which restored the ar1. I implemented Pmans sense mod (Cheers).
I plugged in the PCB and got random vectors, I measured the +/-15v for the opamps in the xy drive circuit and the +15v measured 9.5v. Replacing the 470uf cap on this rail restored the +/-15V but the pcb was intimittent in starting up.
I cleaned the proms and sockets which has improved things but I really need to replace the sockets as it is still slightly touchy.
So anyway the beast is running but I still need the following:
- Marquee
- Back door sheet
- Coin door loom
- Ideally a LL loom instead of the asteroids one I am using. (Or atleast the 24pin connector socket for the control panel)
Cheers
