Lines: 27 Message-ID: <54g60m$oh7@nike.volvo.se> References: <DzJzE0.MBD@maginot.mte.com> NNTP-Posting-Host: cyklop.volvo.se X-Newsreader: TIN [version 1.2 PL2] I have an isa board with ulnxxx chips on output/input 12 bits out 8 in. Open collector or totem depending on chip selected. < 1ms switch time. As delivered handles 50V or 500ma (max power dissapp per 8 bits are 500mw it's the chip that is the limit) It includes a 12/24 v DC-DC converter (can be removed). I have no driver for bsd (although should be fairly straigt forward), it is used to interface dos software with cincinnatti nc-mills. It costs me $ to get maunfactered, i pay > 200$ per board :-( But you *could* use the lp driver and hardware (provided you modify the driver) and optionally make some external buffering. Drive Carefully!
