I have the AX99100 based Axagon card linked by Michael and a SUN2410 based card as well as some computers with on-board parallel port and some ISA cards (and at least one PL2305 based USB adapter). At work I have a XIO2000 + OX16PCI954 based card in my computer. A simple test application shows that the AX99100 can do about 825k register reads or writes per second. The OX16PCI954 card can do about 640k accesses per second. Best regards, Daniel
