'big' as in 'big and square', or big as in 'big and rectangular and tall'? (It's either a custom blob or the +5 to -9V converter). > | dp83910an > | dp8392c These sound like the meat; I don't have a card here in my pile (just checked) with an 83910 on it, so I can't try it out. Anyone else got one of these? > | 16r4bcn Glue logic. > The "dp83910an" and "dp8392c" look significant? Yup. The latter is the 'line driver' part, but I'm fairly sure the former is an 8390 superset part. At any rate, I don't think it's an oddball; the 'dp' prefix is NatSemi's current one for their parts. It should have a sort of oval-shaped 'N' on it as well if this is the case. Well, it looks like we can rule out 'busted hardware' and go for 'weird or not-quite-compatible' instead. 8( Short of building up a kernel with more debugging turned on in the 'ed' driver, I'm at a bit of a dead-end here, sorry. David, as the 'ed' guru, do you have any ideas? > Brian Tao (BT300, taob@io.org, taob@ican.net) -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
