I have a Fastlane with my A3000, 64MB variety. I forget the rev.# of the Fastlane, but the scsi wouldn't work at all with Rev.7 Buster. I had an extra Rev.9 from an A4000 upgrade and plugged that it, attached my SCSI-2 system drive and it worked fine. I think the Fastlane instructions even say there is a workaround so it will work with a Rev.9 Buster, though there may be trouble if there's more than one ZIII card in the machine. I'm planning on trying it with a GVP Spectrum ZIII card.
I wonder how tough it would be to etch your own Amifast-like board?
