I was considering buying a IIci and equip it with a video card for a 19" monitor and an Ethernet card (that's 2 NuBus slots). Now, someone warned me that this will cause trouble for the following reason: Apparently, a majority of software packages get into trouble and crash due to the fact that they don't handle the management of the additional cards (except for the video card) correctly. As we don't have any IIci with 2 expansion cards here, I can't verify this directly. It sounds to me like software vendors would take care of such a problem pretty rapidly... Does this sound familiar to anybody? Right? Wrong? Comments would be greatly appreciated! It's easier to find out this way than after getting the Mac out of the box...

I don't believe that [ ci having problem with more than 1 nuBus card ] is true. Granted, I only have a Supermac ColorCard/24 with Accelerator, so I can't verify it. The only reasons I can think of is 1) Power Supply 2) ci's use of PMMU in mapping its internal video card

I think is was about three times as much and that's the reason why they don't recommend it for use in any of the compact Macintosh IIs that have only three slots and a small amount of power alotted to power them.

Anyway, you should be able to put just about any board in the system. Unless some software you're running is specifically looking for that board, it should do absolutely _nothing_ to the system operation. -- ----- Steve Lemke, Engineering Quality Assurance, Radius Inc., San Jose ----- ----- Reply to: lemke@radius.com (Note: NEW domain-style address!!) -----

Software doesn't really "manage" Nubus cards, in general; that's up to the System software and firmware. One problem that *can* occur, however, is if you're using cards which exceed the wattage specs of the IIci (or IIcx); although Apple issued guidelines for card manufacturers long ago, many (particularly high-bit- depth video cards, *including Apple's 8/24GC*, apparently) draw more than they're supposed to, which can shut down the bus and prevent the machine from powering up (I experienced this myself with a Radius card combo). I'd say try before you buy... John Heckendorn /\ BMUG ARPA: bmug@garnet.berkeley.EDU A__A 1442A Walnut St., #62 BITNET: bmug@ucbgarne |()| Berkeley, CA 94709 Phone: (415) 549-2684 | |
