Texas Instruments TI-99/4A
This wasn't the first computer I ever used. (That was a TRS-80 Model I in
1980, when I was in 4th grade.) This wasn't the first computer for which I
wrote software. (That was my grandfather's TRS-80 Color Computer.) It was,
however, the first computer I had at home. We bought one in
early 1983, not long before TI dropped support for the machines. We had a
fairly basic setup...16K, a Radio Shack tape recorder for saving programs,
an old Sears 19" TV for a monitor, and a handful of cartridges. Upgrades
that cost more than we paid for the computer in the first place led us to
get an
Apple IIe a couple of years later
(which has since morphed into the
mighty "Stealth IIGS"). The computer, along with the TV, got left behind in
1988 in
West Germany (as it was then called) when we returned to the States from an
overseas posting.
It's 20 August 2001 as I write this. Three days ago, I received a package
with a TI-99/4A and a bunch of other goodies from an
eBay auction. It came with almost all the cartridges I had back in the
day, plus many more that I didn't have (including a couple of TI Extended
BASIC cartridges...if only I had had one of those :-) ). Here's the
inventory:
-
The computer itself, in the older black-plastic-and-brushed-metal
case with matching black keyboard, power transformer, and RF
modulator.
-
One pair of the standard TI joysticks.
-
The optional speech synthesizer (mondo cool gadget).

The starred cartridges, plus Car Wars, are what I had the first time around.
(Early Learning Fun was for my sister, but I think she never used it. I
tended to "monopolize" the computer...both the TI and the Apple that came
after it. :-) )
The out-of-the box hardware configuration for a TI-99/4A is something
like this:
-
3-MHz TMS9900 16-bit microprocessor, one of the first 16-bit
microprocessors, and the first used in a PC
-
16K RAM, expandable to 48K.
One expansion port on the side. Some peripherals, such as the
speech synthesizer, plugged into this port in daisy-chain fashion.
The Peripheral Expansion System was also available, which plugged
into this port and offered eight expansion slots for memory, serial
and parallel interfaces, disk controllers, and more.
-
Integrated 16-color graphics with a 32x24 text display with
reprogrammable character set and [additional capabilities that
I need to look up]
-
Ports for two digital joysticks and two cassette recorders, the
latter for program and data storage.
-
Integrated 47-key keyboard with upper/lowercase input and
auto-repeat.
In the past few weeks, I've built up a small collection of 99/4A links.
Here are some of the better ones; they have more comprehensive links
themselves.
