First chip ready

Agreed.  But, I'll modify this a little bit :-)

I was originally going to desolder the chip.  Then I thought that with my
clumsy hands that I would screw something up.  So, here is my plan...

1) I bought a 34 pin Wire Wrap Male Protected header.
2) I will cut off the last 6 pins (2 rows of 3).
3) Insert the appropriate end of the Memcal into the header.
4) Insert the wire wrap ends of the header into the programmer.
5) Download the EPROM image and verify it.
6) Cut of the EPROM from the Memcal
7) Desolder the legs
8) Solder a low profile ZIF into the memcal.
9) Burn a new chip with the previous image (or the modified image).
10) Put the new EPROM in the ZIF
11) DONE!
