I'm trying to fix my Area 51 Site 4 board, and I think the main chip on it is fubar. Have a feeling it was overvoltaged at some point. Watchdog is resetting and there's no activity out of the chip anywhere.
Anyone know if the main chip Alctel 42MX09 still available as it came from Atari (or otherwise)? If not, is there any resource to find parts like these in other crap? I know its apparently good for parallel use so maybe it can be found in printers or some other computer junk. I have access to practically endless supplies of computer crap.
Some places actually list it for around $50. A bit much for shotgunning purposes. I think I heard Happ and Betzon fix these things so there has to be parts available. I'm also curious as to what Happ or Betson charge to fix these things (Betson is 10 min from my house) but I have a feeling its more than I care to waste on it.
Chip looks like this:
