the network controller is an asix ax88796 which is ne2000 compatible. linux and freebsd drivers available.
datasheet: http://www.asix.com.tw/FrootAttach/datasheet/Ax88796.pdf
the usb controller is the philips isp1161a
datasheet: http://www.philips.semiconductors.com/acrobat/datasheets/ISP1161A1-03.pdf
i believe there are are open source drivers available.
the ide is a custom device, but provides the standard register set, if someone was serious about writing a driver for it then details could be made available.
there is also memory mapped flash (2M as standard) on the card for storing drivers or general usage, on RISC OS this lets us start the machine with our drivers inserted in the OS, and boot from any attached device.
they're not that different in the signals that they use. pin out is as follows.
pin a b c
1 0V D[0] 0V
2 LA[15] D[1] -5V
3 LA[14] D[2] 0V
4 LA[13] D[3] 0V

What's the anti-troll code? That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
