Those were a lot of the important early ones. There were lots more including examples like:
TrueBasic - the modern remake by Kemeny and Kurtz at Dartmouth. TurboBasic - Borland's answer to QuickBasic.
etc, etc,
There's even XBasic or wxBasic which promise cross platform compatibility between win32 and *nix. Basic may not be the most elegant language but it's fast and gets the job done.
Actually it's improving and, in the newest plants, is quite a bit higher. Power generation is often well in excess of 90% efficiency. However, the distribution system is lossy -- around 30% of all power generated is lost as heat in the lines and transformers before it ever reaches your home or business.
And you've just essentially described how a switching power supply works, except that the regulator is a comparitor & reference controlling a chopper which feeds a big capacitor and...
While a parallel port seems to be a good idea, I wouldn't do it. Hooking up a motor controller to a parallel port is a good way to blow the southbridge chip on your motherboard.
If you insist on using a parallel port for control, use optical isolation on your board (the chips are cheap and easy to obtain), and, don't try to draw drive power from the port.
Words of advice from a proffesional...

there's a darwine project (check sourceforge) which is trying to port wine to darwin. It's not done yet (still in alpha stage).
The store would have only one "server," two would be too expensive.
I've looked at a Pizza Hut installation (they run SCO server software, similar to McD's)... It's a PC running SCO unix in the back office, hooked up to the POS terminals using serial ports. Once a day it dials up (POTS modem) the "home office" to upload the days transactions and place orders.
While it's true that some of the very small cases are quite expensive, If I remember right,
VIA designed the board to mount into an ATX case. (although it'd be awfully empty)
I've looked at my $39 mini-atx case and it appears the mounting holes for a mini-itx board line up with holes already drilled on the mounting plate.
That's a C3 "Ezra". It had a FPU that ran at 1/2 the clock speed and only had a 133MHz bus.
Since then they've come out with the C3 "Nehemiah" which has a full speed FPU and has a 266MHz bus. They've gotten somewhat faster; although, I don't have any benchmarks for you.
Man, I'll see you there. I'm running my 20year old pickup truck, loaded with a bunch 'o equipment in the back, and couple of computers built from scrap parts.
I suspect (based on other's posts) that you just have the wrong adapter.
Having said that, we just went through a similar problem with USB-Serial converters. USB is well defined and RS-232 is ancient (and well defined). Yet, our product (which meets the RS-232 spec strictly) didn't work if the customer was using a USB-Serial converter. We found the converters (we tried several brands) were doing some subtly "unusual" things with both the signals and the serial port registers. We ended up modifying the product firmware and the software on the PC side to make allowances for these converters.
This may be your problem. If that particular converter hasn't been tested with your model keyboard, by the manufacturer, it may have problems.

It would be very un-cool.
yes you would. To get go from 120V to 12V and do the same amount of work you need 10X the current.

They did a crappy (Microsoft-centric) job of the Basic language time-line.
Living next to Langley AFB in Virginia, I can tell you: It's LOUD! But you get used to it...
They apparently did this for tons of apps. Search your system Registry for AppCompatibility
buffers or driver IC's don't provide enough isolation from what a motor can produce in the form of back emf.

I don't know what you were looking at; but, my Dish Network dish is only 18-20"

The later generation "Nehemiah" C3's have a full speed FPU and a 266MHz bus. This should make them benchmark much better.

They have the taste of money now... They're addicted.

Actually, the sales of their cash-cows (Windows and Office) are falling... And MS is worried.
Oh yeah, In my day we used a teletype to some remote (unknown :p) machine. Boy, those were the days...
The hardware is free; but, you'll need to pay for a software & service subscriptions to get it. That'll be $1,499/yr for 3 yrs please.
Maybe a useful device for data access; but, I'll still want a full size keyboard and a decent (>=17") monitor to do real work on...
