68hc912b32 preogrammer schematic need pls.

[Chriss]

Hi!
I have to r/w this type of uC 68hc912b32.
Can somebody help me with a DIY programmer schematic?
I don't use often Motorola uC's and I won't buy an expensive programmer tool for this uC's
if possible to make something at home...

Thank you very much.
My best regards.

While not DIY, this is a lot cheaper than the official solution.
