^ I can't seem to find them for purchase on the Homepin website?
I haven't put them up on the site as the original RAM is soldered to the board and the tracks are VERY delicate and easily broken unless great care is taken.
I'm a little unsure exactly how to go about offering them - I had thought I might sell them with a new replacement WMS MPU but I'm open to suggestions.
I've used a similar product in a Bally Truckstop, no soldering required as was socketed. I am sure Mikes products are as good if not better.
I second above what Mike said re original ram on WPC games. The tracks are VERY delicate and I would suggest unless you have a very good desoldering station or are very skilled to pay a professional to fit.
