Ello bud..... saw your post on one of the Facebook pages earlier about this..... bit confused by what you mean about these springs though, as I have no knowledge sp.ace (The system hardware), using springs anywhere..... do you mean pins on like ROM chips or Game Cards at all?

I can only assume they mean that some pins/legs have snapped off the ROM chip/s. We all know how easy it is to do... I certainly have a few times in the past!

You need to ask someone to burn you a new EPROM then. A few people on here have the facility to do it.

OK.... for this vintage of machine, we should be able to help, although you maybe able to get assistance from MPU Mecca too.

One thing I would like you to do though, is take a pic of the rom in question that has been damaged, as in some cases, it maybe possible to repair the damaged pin, by soldering another one to it, assuming these is enough exposed metal to which to solder to..... done this trick once before on my Maygay Simpsons (Blue, Epoch), and it worked fine :)

 

Also if possible, could you give use the reference code that is stamped in to the rom, just in case this pin trick does not work, so whomever can burn you new ROM's, can make sure they have the correct blanks to hand.
