I'd like to find a spare board but it's very rare...

anyway never seen a PCB with so much strange components, like 8T97 and 8T28

Glad to know that you're looking to purchase a working pcb so that you can give me back the one I gave you on loan.
Yes, that NOS, clean, shiny, working circus pcb that you've tortured and killed without mercy. :evil:

P.S. I want to  remember you that the "Merchant of Venice" rule is valid for that pcb. ;D

Well, it's actually not something you expect....if it wasn't visible without removing the part it may have been a long search....
