Closed zip chips for ram module

I'm trying to find some zip chips to upgrade a memory module for an A500+. I need 1Mbit x4 zip chips and I need 16 of them. Does anyone know where I can get hold of some? Or alternatively is anyone selling at Supra Turbo 28?

I'm looking to buy a Supra Ram 500RX (the one I have is faulty) or a Supra Turbo 28. Has someone got one they would sell, or at least borrow me (money up front) so I can test whats wrong with my 500RX.

Thanks in advance

Hi, i have zip chips

Hi Daz, this might help you out.

I ordered and received 32 used TC514402AZ60 Zips from UTSource a couple of months ago to upgrade my A3000 memory. They had reprinted TC514402AZ60 labels on them but were actual TC514402AZ60 underneath.( I guess they wanted them to look new?)
All of them worked for myself, but there is a possibility of receiving some fakes as they had reprinted labels on them.
