if i have removed STC, diodes and resistors do i have to reprogram GAL and add three wires as well? i saw somewhere that only atmel needs programming.

hi all new DKS
trying to repair 908rl chinese clone ,when the soft starts gives an error (time out ) what is the problem . another thing i read in garageforum the Gal could be removed and replaced with some connections ,is this help to upgrade RL interface's to 11.2 ?!!!!!
Here are my pictures:-
Your cable is a RL cable. STC, R and reseter/diode was unsoldered, the GAL was unsoldered and resoldered, i suppose it was reprogrammed. If not, must unsolder again and programmed with the .jed file (is posted on dk, few pages before/earlier).
And must resolder GAL and solder 3 wires like in Aminebot's tutorial.
After, reprogramm ATMEGA and eventualy FT232RL.
But, my opinion, who soldered on your cable atmega pins and resoldered GAL, he don't work tidy. Try to use RMA-223-Amtech-1010 flux and a good iron.

Seems I have a lot of work to domaybe scrap it off and get a newer version?
I don't have access to GAL programmer.
Thanks guys (and yes the soldering is crap)

well the Atmega has been programmed with 1.84 and verifies OK. Security fuses have been set and read back OK. FTDI has been updated and cable is now recognised as a rosstech cable.
So far so good, off to hunt down loader software and try 11.2.
thanks for your help.
It can work and on the contrary if to use other loader.
Here proof.
It is a clone of a cable based on the FT232R chip.
