Well OK! The great Amiga.org folks spoke and gave me everything I could have needed on the Kickstart thread. So having upgraded to 1.3, and gotten opinions on my next kickstart upgrade, I nevertheless decided to try the accelerator. It's a GVP 68030 card with the RAM expansion (8MB, there's other slots not full either!) and the hard drive controller (it came with a hard drive too!)
I plugged it into the slot, attached the hard drive (guessing at the Pin 1 orientation since nothing on the socket that normally indicates it was there) with the cable the eBay seller provided, and fired it up. Voila!! It worked first time and I have a DH0 (233MB) on my screen and a RAM Disk too. It looks like the seller ran the default install/format utility on the drive as there isn't very much there.
This is not so much a question (yet) just more of a comment on my success (which has been good so far).
I have to admit, I have no idea how to "shut down" the amiga other than just turning it off, but of course that scares me now that I have a hard drive.
Next, I move to the software forum for some postings about how to get games onto my hard drive, now that it is all up and running!!
