Which tools do I use?

Well, so far it’s quite straightforward… a digital multimeter (I use the Velleman DVM-4100), a 30W soldering iron and a whole range of screwdrivers and pliers.

In preparation of repairing the CPU board, I have bought a Willem EPROM programmer (off ebay), two 2532 EPROMS (oh yes, I found some) and made a logic probe as described on the flipper-pinball-fan website (see my links).

Now I’m waiting for a PCMCIA Parallel port card for my laptop, so I can connect the EPROM programmer and make me a copy of Leon’s test EPROM from the flipper-pinball-fan website (see my links). Then the testing will continue!
