The only issue that I have is the SCSI2SD boots slower than the Amiga, so when I power on the Amiga I have to wait a few seconds then do the A+A+Control reboot three finger salute (or whatever it is.) Before it's ready the Amiga just sits at a white screen forever, but after a reboot the SCSI2SD is ready and it boots fine.

> Is Inertial Computing a good place to buy from? I was looking at their website. It looks like the latest v6 might be the way to go for Amiga, VAX, and Alpha. With v5.1 making more sense for my PDP-11/73, due to cost, it’s not like I’m going to get 10MB/sec on a Q-Bus backplane. :-)
They are. I bought from them just a month and a half ago - the replacement for the "Drilled" board plus another for my PDP-11/xx (53/73/83 depending on which CPU board I feel like using) and it was delivered in 3 days despite shipping from CA to TX in these COVID limited days.
I haven't tested but you're probably right in that a V5.1 is probably good for a PDP QBUS SCSI card.
