A3000 SCSI Replacement Chip
« on: August 04, 2008, 11:26:49 PM »
Restoring my A3000 and like to finally get rid of the PROTO WD33C93 chip.  Found this one on eBay

Will this do the trick?  I have already scavenged my local PC junk stores and cant find any 33C93 based SCSI boards.  Or if anyone knows a cheaper place to find one, I was only able to find one $1 cheaper w/ $50 minimum order...

Oh, I thought these PROTO chips contained bugs and rev.8 models fixed some issues.

I feel dumb now...  Wasn't certain what the revision number was on that chip.  Thanks for clarifying for me.

The last one on eBay sold for over $60 US.  I'd rather buy a Buddha IDE card for that price and just leave a single drive on the scsi chain.

My main problems are cdrom drives.  I have tried the few I have on my 3000 and the disk usually will be unreadable.  If I put the same drives on my TrumpCard Pro I have no problems at all.  So I just assumed that the 04 chip was the cause of the problems.
