That would be "address width", not "data width". There are very
different things.

BTW, I've spent a lot of time programming computers with 8-bit data
width and 16-bit address width. The 8088 used in early "IBM clones"
had 16-bit data width and 20-bit address width.

Yes, it is address, not data that's relevant here. People really get
stuck on improper terminology.

I remember when very few people had an internet connection, and people
kept using the term "half duplex" inappropriately. It didn't seem to
matter that the common modem standards (Bell 212a, etc..) use full
duplex 100% of the time, and can't do otherwise.

The Data bus is the path over which data flows. The 68000
was a 16/32-bit chip. It only had a 16-bit data bus. While its registers
and
operations were 32-bit, it could only get data from memory 16-bits at a
time.
It had a 16-bit address bus.
The 8088 was an 8/16-bit chip. It had an 8-bit data bus, 16-bit registers
and ops.
It had a 24-bit address bus.

In the '30's to the 'early '70's duplex meant something different than it
does today.
Half duplex meant that the terminal relied on a computer to send characters
back. There was no local echo. Full duplex, of course, meant that then you
pressed a key, the character would be printed locally without having to be
received
from the computer.

I'd like to offer you some resources for your discussion. First, for Windows XP Mode, which is available with Windows 7 Professional, Ultimate and Enterprise, you can see a video demo at Microsoft Showcase: Windows 7 Professional: Run Windows XP applications and more detailed info at Windows for Small Business: Windows XP Mode. And for 32 and 64 bit issues, there is a FAQ with answers to questions about the 32-bit and 64-bit versions of Windows is at Windows 7 Features: 64-bit Support. I hope this helps you out.

I run XP mode in my Win 7 Pro. I've installed a couple of programs to
test them for friends and they work. Will yours work, I dunno.

What programs are you trying to run?

If you want to run older apps in Windows 7 Professional, there's a feature called Windows XP Mode. It opens apps in a window that looks like Windows XP, with the performance speed of Windows 7 Pro. There's a video demo at bit.ly/Win7ProXPMode and more detailed info at bit.ly/WinXPMode.

All you need do is dl everything from Microsoft...the free virtual PC
software and the free, already activated, copy of XP Pro SP3 to run in
the virtual pc.
Good luck!
