Purchased a 1991 AE TW made for the Mac SE. The Mac SE boots fine and is otherwise stock hardware. After I installed the TW card, the SE just displayes a few random black and white squares on the screen - no startup chime. It's not a checkerboard pattern. Swapped out the Transwarp's CPU & Math co-processor with ones with the same specs, same issue. Re-seated the TW's RAM and tested the modules in the SE. Also tried booting with no RAM installed on the SE motherboard. I noticed there's an empty socket labeled "Y1" on the TW card that might be for an oscillator - but can't find pictures confirming that there should be an oscillator installed in this socket. Never seen a card without one except this AE TW. Please see the picture.Can anyone confirm that there should be an oscillator installed at "Y1". Otherwise, I may just have a dead accelerator.Thank you!
