I got this scanner from my friend some time ago - a great, but old Minolta Scan Multi (not Multi Pro, sadly). It worked well with Windows XP, but - since I run Windows 7 - I needed another machine to run it on. It's old SCSI controller, Adaptec AHA2930CU wasn't working with 64bit version of Win 7.
Until I performed some crazy mumbo-jumbo, that is.
I found the emulated drivers for Adaptec AIC7870. It's the chip that this card uses. And, after installing these drivers (which weren't signed for Windows 7, of course), I got my Minolta to work with VueScan!
Here's the proof:
This crappy picture of a bike I have taken long time ago with an Agfa Isola (or something like that) camera.
I just scanned it 10 minutes ago.
Therefore, if you want your old SCSI Minolta scanner to work under Windows 7 64bit - fear not, as it probably can!
Here are the drivers should anyone need them:
P.S. I take no responsibility if anything goes wrong. But I encourage you to try it!
