Cms scsi card

Hello I'm looking to hook up a scsi hdd to my apple iigs. I am considering a cms card because they seem half as sought after by collectors as the apple cards. The drive I'm hooking up is a quantum hdd in a hobbyist's scsi enclosure, which I've never seen before but it powers on and does its self test just fine. Would a cms card be a good option?

Some people were fans of it but I wouldn't buy one myself. I've used one but I prefer all the other SCSI cards over it.

I have one- it works fine. It allows for multiple ProDOS partitions and you can choose which one to boot from, which is a nice option. I think it also allowed for HFS partition(s) in GSOS, but it's been a few years since I booted it up and played with it.

It's perfectly fine if you can find old working SCSI drives, but that in itself is a challenge, as most surviving drives are large-capacity 80-pin server drives from the 90's and early 2000's.

I used one some years back, and while they are a bit quirky, they work perfectly fine.

There are two main releases of the ROM for this card and I would highly recommend using the later firmware as it gives you a lot more flexibility. IIRC the early version of the ROM has hard coded partition sizes - I *think* it just splits the hard disk up into partitions of 32Mb and a further partition of whatever remains after that.

The later firmware has more configuration in the ROM - you press a particular key to get to the configuration menu (sorry I don't remember the details). From memory, I think you can custom partition the hard disk using this ROM.

One other thing: there is a driver for GS/OS that allows you to have an unlimited number of partitions - I remember having something like 25+ partitions at one stage. It was painfully slow on bootup as GS/OS scanned each partition.

It was incredibly difficult to find this driver, in fact some illuminaries in the community doubted it's existence, but if you (or anybody else) wants a copy, I *should* be able to dig it up again.

Cheers,
Mike
