High all! I'm resurrecting a Mac II that the school board in its' infinite wisdom (sarcasm) decided to toss in the dumpster along with 3 IIci's.
I've already integrated the IIci's into my Rube Goldberg LAN and now I'm starting on the II. (Six, count 'em, 6 expansion slots!!!!!) ((I've got enough sundry NUBUS video cards that I'm going to put them all in!)) (((How to humiliate a windoze drone, show him a 15 year old Mac running 6 monitors! :-)))) Well, I opened it up and sitting on the left side is a strange looking ..... something....... which I'll try to describe. Sitting at a shallow angle is a card that says: DayStar Digital Powercache. This thing, which will fit in a regular NUBUS slot, is mounted to a (daughterboard?) that mounts to the main board via two square (1.25" square) sockets (on the daughterboard) to the same size and shape collections of pins on the motherboard. This thing says: DayStar Digital II Adapter. My experience with Macintosh began when I bought my PowerMac 7100/66 in 1994. So I've never used anything older than system 7.5 or seen anything like this Mac II and the IIci's. They all seem to run just fine on system 7.6.1 so I'm happy there but this strange setup inside the II has made me curious. What is it? Why is it? What's it supposed to do? What's it really do? Is there anything else I can do with it? Are there any other questions I should ask that I don't know about? GURU 2.9 says that I need a PMMU (Paged Memory Management Unit) chip to enable memory configurations greater than 8MB. Where should I look for one of these? Where does one of these go? GURU also mentions SIMMs with a PAL chip or Timing Compensation circuit. And then there's something about installing Mac IIx ROMs..... What have I gotten myself into??? Any help will be more than appreciated! (All I want to do is run 6 monitors!) (( I have a Daynaport E/II-T NUBUS card that has a monitor port AND a RJ-45 plug on it so I guess I can hook into my LAN without losing a monitor.)) (((On that card there's a switch which I hope isn't for selecting either the monitor or the Ethernet, is there anyplace to find out?))) I DO realize that I've been lucky to avoid strange electrical noises, smoke and/or destruction of components, or is the Mac intended to forgive fools like me when they experiment without RTFM? Sorry about the length of this babble but I'm half excited and half scared if you know what I mean. :-) Thanks for any help, ideas and/or suggestions. -- --- Peace, Shakes --- "Knowledge is a deadly friend if no one sets the rules.
