A year ago I was lucky enough to get my hands on a GVP 4060DT card with a 50MHz 68060 and 128MB of memory.



Now it has taken me some time to get the card configured right, SCSI running properly, etc. Things I found out the hard way,

- The card does not seem to play nice with the Phase5 040/060 libraries. The GVP one is more stable and the libs from MMULib give a nice boost.

- There are several different cards labelled differently. I checked the docs on Greg Donner's 4060 support site, but my card has on the board "A4000D 68060 Rev 2", which is neither of the two cards mentioned in his (mirrored) documentation. Eg. the jumpers in the docs for the A4060DT for 040 / 060 / 5V / 3.3V are set differently than on my board. But the 060 works...

- SCSI is OK speed wise, runs the Acard SCSI-SATA bridge really great, but setting up PFS / SFS for the 4+ GB partitions is a nightmare.

So now I'm faced with stability problems. My muggy will stall and lock-up quite often, and I have WHDload issues. I suspect something with memory timing, etc. but I fail to come up with a good jumper layout on the board.

Now, are there still other GVP 4060 users out there that are willing to share some experiences (PFS / SFS, jumpers, ...) with the card? A picture or list of your jumper layout would be great too. Overall it's a really great card, but takes some tinkering to run properly is my guess...

I don't have an A4000 or 4060DT myself, but I did find this on Doobrey's homepage that could help you with SFS/PFS not installing in the RDB.
http://www.doobreynet.co.uk/amiga.html Check out GVP tekscsi patch to fix the bug in the EPROM.

I see your EPROM is soldered directly on your board, but I'm sure there's someone who might be able to desolder it and replace it with an EPROM socket if you're unable to do it yourself. This'll make swapping the EPROM a lot easier.
