Thanks for your quick response. I will take a look.
I checked and the programmer for that chip Mini Prog 001 is no longer available so I will open a case for you with Cypress.

Cypress say the following :We kindly mention that irrespective of the number of pins if any of the part that has ISSP_SCLK and ISSP_SDATA , you can program the part using Miniprog 3. The 8 pin CY8C27143-24PXI device actually has ISSP pins. So you can program the chip using Miniprog 3. Please go through Miniprog 3 user guide obtained from the link below which says that it can support ISSP programming also. Here is the manual for the MiniProg3. http://www.cypress.com/file/44091/download
