This might be a long shot but I'm looking for a Sonnet 100 MHz PowerPC 601 Presto PPC for my recently revived Quadra 610, so I'd require the adapter also. I might also be interested in other 601 PPC upgrades if available. Tried an 040-060 adapter first but that didn't work

Mods please just delete this thread. I didn't realize how rare these cards are now and don't expect I'd find one.
