I'm looking for the technical reference manual for 3Com's 3C505 Ethernet controller. This manual is mentioned in several drivers for that card (Linux, DOS packet drivers, etc.) - however, I could not find an online copy. This manual would be useful in providing Ethernet emulation support for an Apollo workstation emulator (Motorola 680x0- based machines with 16-bit ISA slots...) - the 3C505 was the only OS- supported Ethernet controller for those (since Apollo's usually used their own token ring-based network).
So, if anyone has access to that document, I would be happy to obtain a copy.
Best regards, Michael Engel ( firstname.lastname@example.org)
