Greetings!

I spend too much $$$ on an SE that had a Brainstorm accelerator in it because I was very curious.
I could see from the listing it was running 1.2 Firmware and I had found the update files for v2.5 so I was feeling good.

Needless to say, after a lot of work and floppy creation, I bricked the card. (Not sure what the issue was as the card was detected and it was flashed, but w/o a hard drive in the system its possible some part of the install did not finish)

I will attach pictures in hopes of someone telling me that I might be able to wipe/reflash based on the 4 connectors on the main board.

Thanks for any help you can provide,
David

P.S.

I included a picture of the custom SWIM chip. If you remove the PDS card, but leave the SWIM in, the machine does not boot. The seller was very kind and sent me the original WIM ( I think) that I saw in another posting, so that I can try to put it back to stock and start from scratch if it can be reflashed...
