Well, after some head scratching and many late nights I still can't figure out why this stubborn Supra thing refuses to see my KingKong sized 40 Mb Conner CP3040 hard drive?!
Setup;
A500, really basic here. Rev 6 mobo, Kick 2.04 / 1.3, 0,5Mb Chipram, 2Mb SupraDrive mounted "fastram"...
Prob;
First of all, the boot time is slooooow, it takes several minutes to boot darn thing, but then only floppy disk is found... After I load Supra setup disk, I can see and use hard drive normally, but after reboot all is the same (no HDD!). I tried different SCSI ID jumper settings on Conner drive, no luck. I used termination resistors from original Seagate 20Mb drive (Conner had empty sockets). I even tried external cable mounted termination thing with no luck... So, is there "simple" solution to this game or should I throw my cherished 40Mb monstrosity out of the window and go with ACA500? 
Any help would be greatly appreciated!
Did you buy the latest ROM revision for the SupraDrive XP? There was someone selling it on this forum a while ago, and on eBay. Not very expensive and fixes a lot of problems / compatibility. Do a forum search for the drive name to find those threads.
Last year I set up one of these on a similarly equipped A500 and it worked fine with a 105 MB drive installed (but I had purchased the latest ROM for it some years previously).
