Thanks for your reply - I also found the following on Dontronics page re Warp-13 ... I've got a clearer picture in my mind now: ****** Another major upgrade to the WARP-13 is the re-design of the wiring to the 40-pin zif socket. The 40-pin zif socket can now socket ALL 8-pin, 14-pin, 18-pin, 28-pin (except 14000) and 40-pin ISP (In-System-Programming also known as ICSP or In-circuit-serial-programming) compatible PICs This is all PICs except the 16C5x and 17Cxx family. Previously, on the WARP-3, the 18-pin zif was required to program the 8-pin, 14-pin and 18-pin 16Cxx parts. As all ISP programmable PICs can be programmed in the 40-pin zif socket, the 18-pin zif and the 28-pin 600mil zif are only required for the 18-pin and 28-pin respectively 16C5x parts. As these are not as commonly used as the ISP programmable PICs this means for many users the extra cost of the 18-pin zif socket can be avoided making the WARP-13 even better value for money. The WARP-13 features an on board ISP connector suitable for in circuit PIC programming and connection to odd pin out devices like the 14000 (Bare adapter PCB supplied) and the 16C92x Quad pack parts. ***** ----- Original Message ----- From: Ravi Pailoor To: Sent: Thursday, May 25, 2000 9:52 AM Subject: Re: [PIC]: was: PICSTART+..Now: Warp-13 accessories question The 8 pin devices are floated on the 40 pin socket. Run the warp 13 driver and click on WHERE PIC. You will get a picture. The blank unpopulated areas are for the 16C5x 18 pin and 28 pin parts.
