- "I see Apple's launched a new range of DOS Compatible cards. Going
- to buy one for that old Mac of yours and finally get out of Macs and
- into the mainstream?"
-
- "Nope. They only work in Macs with PCI buses. I'm buying a 6100
- DOS Compatible instead."
-
- "Why? Isn't PCI the way of the future? Isn't it standard?"
-
- "When you're plugging an Apple card into an Apple Mac, it doesn't
- matter what the bus standard is. All that matters is that the
- Mac and card are compatible."
-
- "So PCI isn't important?"
-
- "Do you think that if I plug Apple's new Pentium card into a
- no-name PC with a PCI bus, it would work? That I'd be able
- to do anything useful between the Pentium on the card and
- the Pentium on the PC's motherboard, like that fabled Pentium
- multiprocessing?"
-
- "Er, no. These cards are for Macs, aren't they?"
-
- "Exactly. Who'd want a PC in a PC when they could just buy a
- complete PC for less than what the PC in a PC would cost them?
- Mind you, I can't see the point of selling a card that meets a
- standard unless you can sell it to everyone who bought into the
- standard. Adopting PCI made no sense to me at all, since it
- broke the 'Mac and card are compatible' rule for the entire
- user base, too."
-
- "Well, you can always plug one of those cards into a new Mac, which
- is what it's intended for. It's not that expensive, is it? You've
- been making noises about buying a new Mac, and you can
- share memory with the Mac motherboard, after all, so you
- save on buying RAM, right?"
-
- "Nope, these new PCI cards can't share motherboard RAM. You've
- got to buy separate RAM for them."
-
- "Really? How much can they take?"
-
- "Well, that new Pentium card maxes out at 24Mb of RAM."
-
- "24Mb? That's not much, is it? NT likes at least 32Mb..."
-
- "Are you sure NT will run on these cards?"
-
- "Ah. But you're buying a 6100 DOS Compatible?"
-
- "Yup. Unlike the PCI cards, the 6100 card shares up to 64Mb of
- motherboard memory, for a performance hit, mind you. The entire
- box costs less than one of those new Pentium PCI cards. It's been
- seen running Apple's port of linux native in select
- locations now, too. No idea when they'll port linux to the PCI
- PowerMacs, and given their A/UX porting promises I'm playing safe."
-
- "Can't you install x86 linux on the DOS card right now, anyway?"
-
- "Nope, there's a question of drivers. When I get my hands
- on the powerpc linux it ought to be possible to reverse-engineer
- them and get linux running on the dos card in a fraction of the
- time it took to do the powerpc linux port - actually, Apple
- might have done this as an interim stage for driver development
- anyway - but sorting out the networking aspects of two unixes in
- one box with only one lot of ethernet hardware could
- be tricky, to put it mildly. Could become an interesting
- two-screen Xserver, though, although the 16" screen resolutions
- are barely up to it."
-
- "So instead of using this 6100 to run Mac and Windows at the same
- time, you're heading for linux and dos or windows at the same
- time, but you really want to use it to run Mac and
- linux on the DOS card at the same time, and possibly linux with
- linux at the same time."
-
- "Right. Although I'm going to be stuck with choosing
- between linux or MacOS with DOS or Windows every time I boot,
- until I get it all sorted out and get rid of the Microsoft
- bits. Linux OR MacOS? Some choice. I want linux *AND* MacOS,
- not windoze and go-on-pick-one."
-
- "Couldn't you run the Mac Application Environment on linux?"
-
- "MAE's only available for HP and Solaris machines. Not linux.
- The idea's not that bad, though. A/UX sat under System 7, so
- you could do something similar, but linux is free and Apple charges a
- fortune for MAE, which would mean that Apple would then go and
- do something stupid like try and charge for linux. A 'proper' PowerPC
- MAE as a linux/Mac environment combination would really please all
- three of those remaining A/UX users, and that's a good enough
- reason for Apple not to do it. And if Apple did do a PowerPC
- MAE on PowerPC linux, there would be pressure for MAE on x86
- linux, then everyone would buy fast PCs and run linux with MAE on
- top even though x86 MAE wouldn't be a patch on powerpc MAE, and we'd
- finally discover that Apple was a software company. A powerpc
- MAE on a powerpc-native linux running on a powermac would really
- kick ass, though. Those A/UX guys would love it, although they'd
- probably grumble about all the things that A/UX got right that
- linux gets wrong, religious fanatics that they are."
-
- "But if MAE runs on Solaris, can't you just buy it for your Sparc?"
-
- "The 6100 is only a few hundred dollars more, and it runs PowerPC
- binaries. MAE looks pretty bad next to an LC475, and won't do PowerPC
- native apps. It's really a way for Apple to repackage and resell the
- neat 68K emulator code that made the PowerMacs possible,
- nothing more. They've made noises about doing PowerMac emulation,
- but never in a million years will they do it. Emulating a RISC
- processor with a different RISC processor is a development
- nightmare, and performance would just suck."
-
- "So if you want performance..."
-
- "You go and you buy a real Pentium PC and stick linux or NT
- on it and you go and buy a 604-based Mac for doing Neat Stuff
- and you run real commercial shrinkware unix apps on the Sparc.
- You don't dick around with these weird 'compatible' cards."
-
- "Exactly. Right. So why are you buying a 6100 anyway?"
-
- "Oh, I like Macs, budget money is tight, they're dirt cheap and I
- wanted a memento of Apple. The DOS card is just a bonus.
- Besides, Word on the IIsi is a dog and I loathe using Framemaker
- on the Sparcs."
