| Quadra 700 with SCSI2SD? |
Posted by: LazarusNine on 2015-09-13 15:26:21
Has anyone had any luck using the SCSI2SD in a Quadra 700? I have one for my LC III, and it works really well. I'm intrigued by the new, smaller SCSI2SD, but the compatibility list still only includes the LC III and 475 (or the Mac II under System 6). Does the SCSI2SD generally work on other SCSI Macs?

it will work great for you in the q700!

It's worked great in every Mac I've tried so far.

What is the performance like?

the SCSI2SD and SCSI2CF's that i have messd with have been slow compared to my 10K 2.5" 73gig SCA to SCSI screamer solution.

Yeah, those drives I got from you are pretty awesome. I have one in my centris 610 and the other in my quadra 800.

seems like the guy selling the SCSI2SD's now here in the us, outta cali… he is selling them for 60 each /w sd card if you buy 2 or more.. so that is pretty good deal. one thing i like about the scsi2sd is that it can run from the bus, off termination power alone. I Think Mike McMaster really hit it home with that feature!

I am thinking about picking one up for a Mac IICI I picked up. Hard drive was toast.

If/when I get some money, I will definitely consider getting one of these "2nd-gen" SCSI2SDs. It would go neatly inside a Plus modified for internal drives and term power.
Or a Portable (for which I'd need a 50-to-34 pin adapter and a new and/or repaired LCD cable).

the SCSI2SD and SCSI2CF's that i have messd with have been slow compared to my 10K 2.5" 73gig SCA to SCSI screamer solution. Yeah, I've noticed this as well. I pretty much view the SCSI2SD as useful in a 'special' machine - in my case, the LC III. However, as wonderful as it is, it's a bit costly (in relative terms depending on a person's disposable income, or the level of their spouse's understanding) to outfit one's entire collection with SCSI2SDs. I've pretty much replaced all of my Macs' hard drives with 2.5" 10k SCA drives. I mistakenly bought a couple 3.5" SCA drives, which I was worried wouldn't fit once the adapters were on, but in Macs like the LC 630 and 7100, they've been fine. All that said, I'm thinking about getting a second SCSI2SD to act as an external hard drive that I can boot from to install systems and transfer applications over from.

yeah personally all i need is a SCSI2sd that can be poped right on the back of any mac and works. just a nice little card that has a Male Db 25 pop on and rock. that is what i think most people would like... then the guys that don't like opening up their machines can be happy too.
pop on and rock, Bus powered, heck even with the Mac Plus, you could just put a jumper where the diode is suppose to go to allow termination power... same with the dove scsi add on boards too.

I know the topic is about SCSI2SD, and mine just arrived, so I hope I can boot up my Quadra this evening. But I am curious about the SCA to SCSI solution. Is it this adapter that is needed to get it working?

Is it this adapter that is needed to get it working? That adapter gets part the way there, but not fully - it needs termination. Max1zzz is worth talking to if you're interested in figuring out how to modify that board or, indeed, buy a couple boards straight from him that simply do what they need to (that's what I've done).

OK, cool. I'll send a PM that a way then. Thanks!

you could use that adaptor but you wold also need termination so this would work. http://www.ebay.com/itm/SCSI-Terminator-DB25-Male-New-/111444892331?hash=item19f2a21aab
you could also use an inline terminator.
max1zzz on here makes Terminated SCSI adaptors,
sometimes terminated scsi adaptors do appear on ebay as well
but the magic is not in the adaptor or the fact that is has built in termination or not.
the magic is in the drive its self. The Drive has to be fully backwards compatible.
The issue is there most of them are not fully backwards compatible.
so when you find a certain brand that is... its best to stick with that model.

Yeah, uniserver makes an important point on the drives. I've had a lot of luck with eServer 74GB SCA drives if you find them. They tend to be IBM-labelled drives. Think a few of mine are Seagate, for instance. They're still pretty abundant. I recently got two for about £13 on eBay, which I consider a decent price.

If this had a male DB-25 instead... Wow!

A male to male DB-25 cable will do the trick, but I agree...less clutter if the male DB-25 was right on the end of the adapter.
