I don't have a "TAIT Programmer" right off, but if you can use the El Cheapo PICmicro Programmer from Myke Predko
(see http://www.myke.com/elcheapo.htm ) then I have the schematic and board files in Eagle and you are welcome to copy. As it stands the board is 2 inch x 3 inch single sided, I added a 10 PIN HEADER for "OFF BOARD ICSP" and the board has an isolated flood fill (not a GROUND PLANE) to eliminate excess etching, everything is in 20 mil trace width. Attached is a small image file of the board, take a look and let me know if you want the Eagle files.
