On the subject of adapters. Has anyone used a JDM/Ludipipo programmer (Mine's
an18 pin version put designed by Silicon Chip and sold by Dick Smith
Electronics in Australia) to program a 40 pin PIC ? In my case, a an 18F452?

I've been using a breadboard and jumper kit to make the following

Name      18 Pin      40 Pin
MCLR      4          1
VSS       5          12 & 31
Clock     12          39
Data      13          40
VDD      14          11 & 32
OSC1      15          13
OSC2      16           14

Attempting to use IC-Prog set to program an 18F452. However it chews up 100%
CPU and takes about 5 - 10 minutes to program (over a serial connector). And
at the end of it, after another 10 minutes at 100% CPU, it reads back empty
(Code protection is off).

Is it possible to program the 18F in such a way? Am I missing some
connections? I'm after a "no extra parts" programmer (for lack of a better
term) until I pick up a new programmer.

the shape of a house.  I also bought some batteries, but they weren't
