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...

The "PROTO" label means nothing, but if you really want a chip without the label, go for it.

[Splurge]

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

[adolescent]

Yeah, that's an old 02 chip, probably as old (or older) than what's in your A3000 now.

[Splurge]

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

[adolescent]

The one you want should say -08 (although, it may still say PROTO-08 it's still good).

If the SCSI on your 3000 works without problem it's a waste of $ upgrading to a 08. I upgraded my 04 to a 08 and had SCSI errors so went back to the older chip. Problems with the old SCSI chip normaly show up with removeable media.

I wouldn't give up my 08 chip. In my opinion it is the most useful of the upgrade chips. I would go back to the Buster 09 from the 11 before I would give up the SCSI 08. I have never heard of anyone before having more problems with the newer 08 chip. I would give up the newer DMAC & Ramsey chips before I would the newer SCSI! JMHO

How about your first born ;-)?

You make a convincing post. Now, find me two of them

[da9000]

miles and rkauer are right.

They're impossible to find unfortunately.

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.

Buddha IDE card is £37inc VAT in the UK from Amigakit. Trying to get the US price and a link for you but the site looks like it is having issues at the moment.

What problems are you having with the old SCSI chip?

When I ran my BBS I had 2 internal HDs, 4 external HDs, and a 7 CD changer, all with the 04 SCSI chip. The only real problem I had were sometimes I'd need to power things on in a specific sequence.

[Splurge]

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.

You might want to try idefix97 from Aminet. It helps with SCSI problems also. I was having similar problems as you on one of my A2000's and nothing I did seemed to help. Someone here on Amiga.org told me to try the idefix97 and I was thinking probably the same thing as you "I have a SCSI problem, not an ide problem". Well it took care of my SCSI problem and I was sold on the program. It's just an idea but it might work.
