Make ProgSkeet v1.2 WORK as a v1.1

Here goes nothing!

To date the ProgSkeet v1.2 does not work (cannot program NAND or NOR chips - although some success has indeed been reported programming NANDs).

In my quest to get my v1.2 to work I noted that the v1.2 shares much the same hardware as the ProgSkeet v1.1 which DOES work. That is to say the ProgSkeet v1.2 and the ProgSkeet v1.1 shares a common FPGA, the Actel ProASIC 3.

Here I describe how I have turned my ProgSkeet v1.2 into a ProgSkeet v1.1:

Image below shows the ProgSkeet v1.2 board wired up such that it then 'becomes' a ProgSkeet v1.1. Unfortunately there is no getting away from the fact that I've had to add extra hardware in the form of a regulator and more importantly a USB driver chip.




To test my theory, I made a daughter board onto which I've wired my ProgSkeet v1.2:



So the million dollar question: Did it work??
After using my InJeCtuS to program in the v1.1 BitStream (ProgSkeet_Retail_Default111006.dat) and using WinSkeet111205 I attempted to dump and Program the NAND you see soldered to my daughter board.

So far, in dumping and programming a NAND chip... YES! Finally my ProgSkeet v1.2 WORKS.

TBD: Testing a NOR chip (thanks @Sarah1331 for sending me a NOR chip to test).

Hope this is of use to someone ;)

Out of interest and so that the hardware of the ProgSkeet v1.2 can be compared against the hardware of the ProgSkeet v1.1, see my reverse engineering attempts of this hardware here:

Note: In using my ProgSkeet v1.2 as described in the post above, I did NOT change ANY of the resistors on the board - I used it as supplied (R8, R14 and R16 not fitted).
