Last week I found a TranswarpGS for sale in the area. After some e-mails, the deal was set and last monday I picked it up. Together with another Apple IIgs (ROM01), a IIgs logic board (also ROM01) and a Apple 3.5" Drive.
Back home I tried the TranswarpGS card in my trusty own IIgs, only to find I only get a 'checker board' when powering the IIgs. This tells me I have some troubleshooting to do.
I ordered two new 65C816s, which should arrive soon. In the meantime I am going to the oscillator, reseat all ICs, inspect the board, etc....
Some fun ahead!
