I had a Quadra 700 in 2007 I got from the high school I was in at the time. It had a Farallon 10baseT transceiver like one of the ones mentioned here. Had Mac OS 8.1 with Apple Built-In Ethernet. Should have worked like a jewel. Set all the settings, tried to make it work and even when it showed the G3 iMac I had back then in the Chooser, which was only once, it crashed both itself and the iMac. I quickly decided that looks didn't really help me if something that should have worked on greased skids wouldn't work at all without crashing both computers. Today I tried team-building with a pair of Macs that shouldn't even begin to be on greased skids-a 25MHz 68030 Macintosh IIci with 25MHz 68882 FPU and 32KB cache in the cache slot running System 6.0.8 with QuickTime 1.5 (from the CD-ROM software I have for my external CD-ROM), TrueType 1.0 & sample TrueType fonts, After Dark 3.0, MacTCP 2.0.6 that doesn't support DHCP, Network Installer 1.4.5 (I have an Apple Ethernet NB Card I salvaged out of a long-dead IIcx, using a 10base2 to 10baseT Media Converter to make it even more of a long-shot), AppleShare Workstation extension version 3.5, and the G3 iMac has been upgraded to a 600MHz/256MB/40GB/ATI Rage 128 Ultra 16MB graphics/CD-RW AirPort Card plus Adapter & iSub subwoofer iMac running the same basic install of Mac OS 9.2.2 as the lesser iMac I tried to use with the Quadra years ago (500MHz/384MB/20GB/ATI Rage 128 Ultra 16MB graphics/CD-ROM no AirPort Card or Adapter and no iSub subwoofer) and what do you know?
What should b impossible (lesser spec early vintage Mac, running actual late retro software to greater spec late vintage Mac running late vintage software) succeeded where something that should b a piece of cake (greater spec early vintage Mac, running mid vintage software to lesser spec late vintage Mac running the same late vintage software) failed dismally. I'm ecstatic but totally unsure of why what should work doesn't when the stuff that shouldn't work does. I just know I've got someone watching out for me, a guardian angel or something.
I hope you have better luck with the Quadra 700 than I did. I really wanted to like it, but the IIci doing what it would not really makes up for it being the "lesser" Mac.
I just hope sharing my experience is even worth .5 cents (2 farthings for history buffs who research Great Britain.)
