New small multi Rastan / Rainbow Island!

Double check all the pins are sitting in the sockets.

If you put the original ROMs and PAL back in does the original still work? (I assume you tested the board was working ok before)

For my part, all the units I have sent to Darksoft were tested directly and even each of the 8 banks, on my Rastam board.

It was working at the beginning, before the socket installation. Then I tested the game with the socket and I had the same white screen (with few peace of sprits). I thought maybe the pal is dead, so anyway we must swap it to the gal. I installed the multi but same result, bad luck. Do you have an idea of what chip might be faulty ?

It s my mistake I think. Don’t worry

If you undo the process and put back your roms and the pal does rastan work again?

No same white screen with small peace of sprites

then something went wrong when socketing that PAL. Take it to someone that can repair PCBs to fix it or get a new rastan if you can.

this ps is for : @raffy92 … and other interested collectors for this multi .
- for the easiest method of the multi installation and to not risk to lift or damanging any traces or vias during removing IC11 ( B04-09 - is dumped and can be writed on gals 16v8b , file is on pld archive) , the better is to cut every pins of ic11 and then remove the lins from vias with tweezer and soldering iron and then clear vias with desoldering pump or desoldering braid
