Just two short comments on what, on Fri, 09 Oct 2009 15:53:21 -0400,

workhorse printers I use and love have done any such thing.
Well, that's true - but what are you connecting them to? None of the
last three computers I've bought came with a parallel port, and serial
printers aren't all that common.
Connecting to the last notebooks (XP units, both) that *did* have one.
Agreed, the two most recent boxes don't have one (and that's a great
annoyance!).
Quote: But I quite agree with the point you were really making, that newer
printers are being produced with USB ports only (or USB and ethernet).
I still have two ancient Epson printers that are parallel port only,
but they're getting awfully tired. The two HP are both Ethernet only.
And some of them get sold for less than a replacement toner cart for
my other old workhorse, an HP LJ 5L.
Results 1 - 10 of about 125,000 for Gillette "give away the razor".
(0.36 seconds)
"King Camp Gillette" developed the concept of (virtually) giving away
the razor, and making his fortune selling the razor blades. The
companies building "home" printers are following suit. And the paper
isn't that cheap either.
At least you can get a carton (10 reams) of paper from Staples
by submitting -- in a good week -- one $30 Rewards voucher,
earned via turning in 10 empty toner carts  . Probably likewise
from OfficeMax, OfficeDepot, others ... .

Quote: Even with desktops, the needed adapter cards are not as common as they were early on. Mentioned Thursday, the interfaces became part of the motherboard chipset, and that pretty much killed off the after market adaptor cards. For laptops/notebook, I guess it was the perceived market that those who have one will also have a desktop (with access to a printer of some kind), and some convenient means of transferring the file between them.
At my recent visit in the nearest electronic store I could still get
PCI cards for parallel and serial ports. The annoyance comes with the
passing of the PS/2 port for mice and keyboard. I recently got a 6
years old desktop as a gift, but without any additional equipment. Now
try to get a new keyboard and mice with PS/2 as you would not like to
be without keyboard untill the OS starts up! Not that easy today, but
I finally got them from Amazon. Although I learned 10-finger-typing I
could not yet arrive at using up the USB speed of such a new keyboard.
Most likely the hardware manufacturers are also not much interested in
backwards compatibility as this could mean they would be selling less.

I didn't say they don't exist - merely that they are not very common.
If you look at the chips on such cards, what are the 'date codes'
(when were the devices manufactured)?
Quote: The annoyance comes with the passing of the PS/2 port for mice and

I don't know why you are complaining - I've still got several systems
in use with the original IBM PC-AT style keyboard connectors, and
there is one system with a Logitech Bus Mouse (a 386DX-40).

Your headers suggest some version of Windows - perhaps XP. All but
three of the systems at home are at least ten years old (firewall is
the remains of a 386SX-16 laptop, one server is a 486DX266 VESA,
another is an original Pentium 133. They're all running some version
of Linux - a UNIX look-alike O/S. Modern distributions typically
want a P-II and 128 Megs of RAM or better, but it is possible to find
versions that will operate on a i80386SX with four Megs of RAM (they
won't do very much, but hey).
Quote: Not that easy today, but I finally got them from Amazon.
I _think_ I've got several PS/2 keyboards - I know I've got two PC-AT
keyboards in the garage. Mice... I think I've got two PS/2 versions,
but there is a "major" computer retailer locally and they still have
serial mice for sale. New, but no idea how long ago they were made.
Quote: Although I learned 10-finger-typing I could not yet arrive at using
up the USB speed of such a new keyboard.
IBM originally set the keyboard repeat rate (press and hold a key, and
in a moment it will show up as a string of repeated characters) at
10.9 characters per second. 10.9 CPS is normally assumed to be about
109 "words" per minute. There may be a few typists who are that fast,
but certainly not me. The standard PC keyboard uses at most three
bytes to send a character, so 330 bits/second is "fast enough".
Quote: Most likely the hardware manufacturers are also not much interested in

"Planned Obsolescence" - the reason we were buying a new car every
three years (in the 1950s). Manufacturers would like it if they
could get a bit more for their systems - recall that the original
"list" price for a genuine IBM PC-XT (5160086) with 256K, a (full
height) double sided (360k) floppy and 10 Meg hard drive was US$2895
and that didn't include the monochrome display adapter and display
(US$435 more if bought from IBM). Then those darn copy-cats at Compaq
and Everex (among _many_ others) started making "cheap" copies, and
the bottom fell out on prices. My US$59 cell phone has more computing
power than my _third_ computer (80286-6 with 1.6 Megs of RAM).
