I have a "Classic MacII" (purchased in November '87) that I recently purchased a Radius Pivot display for. I've had two cards get delivered apparently DOA ... I tried it on a friend's IIx, and it also didn't work. Symptoms: card does not get recognized on boot, Pivot CDEV does not show up in the Control Panel. Anyway, someone from Radius mentioned that on the old MacII ROMs, there was an incompatibility with large monitors (specifically, he said, NuBus cards that address more than 1 Mb of memory). I've called *every* Apple Authorized Dealer in Manhattan, and they *all* are idiots! No one even knows what a ROM is?!?. Me: "Hi, I'd like to know what it would take to get the most recent MacII ROM set?" Them: "Don't you mean RAM?" Me: "No, I mean ROM." Them: "I'll transfer you to Service" Me: "Thanks ..." Serv: "Hello?" Me: "Hi, I'd like to know what it would take to get the most recent MacII ROM set?" Them: "Don't you mean RAM?" Me: "Thanks ... <click>" A few questions: 1) Aren't MacII ROM upgrades free? My machine is no longer under warranty, and I can't afford the downtime of taking a machine in to let these IDIOTS mess with my machine. I'm capable of soing the swap myself (I did the PMMU, hey, I'm practically an EE) ... 2) Am I barking up the wrong tree? Has anyone else had a problem with ROM incompatibilities? I have a PMMU that I got with Virtual, and it works, so I don't have the ROM that doesn't like PMMUs, but I can't figure out why I would have gotten *two* DOA video cards ... Thanks! /jordan

Jordan Hayes (me) <jordan@Morgan.COM> asks: [ problem with Pivot and old MacII ] I got several replies about this -- thanks. Problem was that I needed a newer NuBus chip, which is soldered onto the motherboard, so it required a logic board swap. I got a dealer to do it in about 45 minutes. The swap is free. Works great, snarfed me a socket for the lithium battery, and my Pivot works like a charm. I'm so happy that I did a full backup and restore on my hard disk. Oh: my serial number on the board ended in -03 -- this is an old one. /jordan

Yes, your description DOES sound on target with the ROM vs Pivot trouble. Yes, you should be able to get a FREE ROM exchange performed by a dealer. Call Brian O'Neal, Third Wave Computing, Austin, TX, 512-832-8282. Tell him I sent you. He should be able to arange the upgrade.

Here's the answer, straight from the Apple's mouth: From: kateley@Apple.COM (Jim Kateley) Newsgroups: comp.sys.mac.hardware Subject: Re: Summary: PMMUs vs Mac IIs -- which ones don't work Date: 10 Feb 90 21:11:16 GMT Organization: Apple Computer, Metro Plaza, San Jose CA Lines: 33 In article <3092@pur-phy> sho@maxwell.physics.purdue.edu.UUCP (Sho Kuwamoto) writes: >You machine will be affected if you have Rev. A ROMs. They moved >to Rev. B ROMs sometime around February 1988. Actually, there are two seperate repair extenstion programs for the Macintosh II. The first, announced in Feburary of 1988, addresses a ROM glitch where NuBus cards with more than 1MB of address space cannot be accessed. This is the "Rev A to Rev B" program. Your dealer can see page 8.4.13 of their service programs binder for details. The other, announced in August of 1989, is for the HMMU/PMMU socket situation where the socket for the PMMU on some units does not have all the necessary pins for a PMMU to function (although it does have enough pins for the HMMU). Your dealer can see page 8.4.14 of their service programs binder for details. In the first case, you would have a problem if you had a NuBus card that required more than 1MB of address space. In the second case, your MacII would not work if you installed a PMMU. Both situations require a main logic board swap, which is at no cost to you. -- Jim Kateley UUCP: {sun, voder, nsc, mtxinu, dual}!apple!kateley S,P,HnS!
