I found 2 of them at a thrift store, (100mb) and both worked just fine. I'm always on the hunt as they are very convenient to transfer large files.

Don't get me wrong, I LOVE scsi. But it super sucks in certain use cases.

I wanted to put scsi into my main PC I have on the workbench. but doing so meant I would need to hard reset the machine EVERY time there was a change to the SCSI bus. I thought the solution would be a USB/SCSI adapter, and I did find one, but its compatibility is 9X/XP only. I even thought of installing a PCMCIA scsi card and dock into the bench system, but again, I was effectively limited to 9X/XP.

I'm actually gathering parts for a TWEENER system with everything I could want in a XP system. quad floppies, scsi, sata, the whole works.

Quad density floppies? Why on earth do you need those?

no, four floppy drives.

360k, 1.2m, 720k, 1.44

Ah OK, I was hoping you had some exotic machine that used them.

Actually, 2.88MB floppy support is built into the vast majority of motherboards between the Pentium 1 and Pentium 4 era. The drives are pretty much unobtanium outside of the IBM ps/2 series, at least at any sane price.

Not to mention the media is like $10 a disk or some nonsense

Bob that tweener system sounds bad ass.

I actually have a new, still sealed in shrink-wrap, Backpack parallel port 2.88MB floppy drive. Don't remember how much I paid for it but it wasn't that much.

The most compatible board I have, which is the test machine mentioned above, is a Supermicro P8SCi. It has 5V PCI, PCI-X, PCIe, floppy, IDE, SATA and has MS-DOS, Windows 2000, Windows XP, Windows 7 32/64-bit and Debian 6 installed. (The P8SC8 variant also has built-in SCSI).

Unfortunately it has no AGP and supports only 1 floppy drive.

I'm using an ASUS PCI-SC875 UW SCSI controller in Windows 10 x64.
However, it was a bit tricky to install an unsigned Windows Vista x64 driver.

NCR / Symbios / LSI Logic 53C875

The USB Zip 250 turned up and it is a little flakey - generally doesn't want to eject when asked but it's good enough for the amount I'll use it! But WOW it's so fast compared to the parallel port one on the PS/2!

This thing works 😁 I just can't find the adapter I need now to convert the 68 pin down to 25 pin 🙁

I had to use these drivers https://www.savagetaylor.com/2018/02/11/scsi- … 0-adaptec-78xx/

I have another PCI SCSI card with the right connector (Domex thing with an Advansys ASC3030 chipset) which I think came with a scanner once upon a time, but I can't find 64 bit drivers for it 🙁

You would have an easier time finding a 68 to 50 and a 50 to 25 adapters, or just the latter and a 50 pin ribbon to use the internal port.

5 minutes on the googler...

and they have a few more to choose from.

all this scsi talk makes me smile. 😁 Up until SSD I was die hard scsi. I still have a couple good cheetah drives and a few good controllers. Maybe I'll put them in a build just becasue its cool now.
