Boca Raton? Isn't that SPAM City?
If I wouldn't go to jail I would probably shoot some of the spammers here.
There is more in Boca than just spam you know. In fact, the birthplace of the PC (not that it was a great architecture) is a 5 minute walk from my house.
Although lately it seems there is less and less tech here. Sigh.

(clears throat) *ahem*
That would be the birthplace of the IBM PC. You know the one - Intel 8088 microprocessor with 64k DRAM, choice of monochrome or CGA graphics, optional 160 kilobyte single-sided 5.25" floppy disk drive. Having been involved with microcomputers since before IBM's entry into the market, I feel obligated to point out that there were personal computers before the IBM PC (like the Apple II, Atari 400/800, Commodore's C-64 and CBM series, Timex Sinclair, and so many others).
Actually it *was* a great architecture because it was so open and easy to duplicate. We've enjoyed commodity "beige box" pricing on most of our hardware for most of the last two decades because of it.

As somebody who cut his teath on the 6502 I can say I am well aware of that... However, I tend to use the term PC as only "IBM PC" and the term computer for everything else. I am certainly no lover of that architecture, the electrically ugly ISA bus, 4-bit latch DMA hacks, and inept firmware that is the PC.

I dunno. It may have been open, but it certainly wasn't good. Electrically the ISA bus had problems (which don't show up at 8MHz -- but the layout of the signals on the connector sure cause problems); the BIOS is pretty dumb. Had it been designed correctly we could have had multi-tasking in 8086 real mode... The DMA hacks on a PC are only now being somewhat removed.
The flaws in that system architecture have been kept around far too long.
Actually, I use Apple & Sun hardware at home (and mostly Sun 4m's for the Sun's), so PC hardware isn't helping me much with cost. PCI is nice but really came out of a somewhat unexpected area at Intel and is amazingly portable and clean -- in partiuclar the clever use of reflection for switching.
But the IBM Boca Plant housed many other projects besides the PC. In particular I happen to posess the sign that was at the front hallway: "The Home of OS/2" -- I passed on the "Birthplace of the PC" sign below it. ;-)
And I was certainly a big OS/2 fan back in the day (the workplace shell is far superior to Windows Explorer, IMHO).
L8r, Mark G.

Yeah - that's what I was objecting to - our opions differ - no big deal. I think now a-days "PC" means an Intel/Windows compatible computer as opposed to "the" IBM PC.

I've had to resort to "Master Thevenin" on a few passive ISA bus backplane projects.

Hey, at least it *had* DMA.

Compatibility is a PITA - sort of an ironic footnote on the ROS list.

Thanks Mark. At one point, I thought OS/2 was going to be "it" - boy was I wrong. It's tough to be in the hardware and software markets while trying to get other h/w makers to adopt your software.

I guess I should be thankful that I've rarely had to worry about backwards compatability. Until about 4 months ago I've spent my entire career designing embedded systems. So I always had both hardware and software under my control.
And boy do I wish I was back in embedded systems...
