Simple LPT to JTAG adaptor howto (GTA01 unbricking)

[Ben Wilson]

I just un-bricked my GTA01 using a simple LPT -> JTAG  circuit and wrote 
a wiki page for the process.

It may also work for doing some actual debugging and should be pretty 
easy to wire up to gta02 as well.
Hopefully someone will find the info useful now that it's there.

Ben.
