I recently acquired a TI Silent 703 on ePay and just fired up. It worked
right away. But I expected it to work at 300 bauds as advertised, and to my
surprise, it clocked at a the head turning speed of 1200 bauds! Did they
hot-rod it later in its product life? It says MODEL 703 at the back, part
no. 2310503-0010. I did not open it up yet. Is this a hardware mod? Is
there an internal switch that can toggle it between 300 and 1200?

Mark,
In a search I found some downloadable reference cards for the Silent 700
Model 703 here:
https://user.xmission.com/~legalize/vintage/docs.html
I thought you were more of a clunky Model 37 or 43 kind of guy.......

I'm drawing a blank on that PN. I'm scanning in the 1985 TI Express
Catalog right now and it only lists the 2310503-0001. I think there is
an int'l version -0003. Even if the serial port would work at 1200,
though, the printhead only does 45 cps. Pic of a supposed -0010 on
Worthpoint, but I don't subscribe for details or confirmation.
However, it would have to have something like the 2 char thermal
printhead in the 780 series to print without buffering at 1200 baud, I
would think. Dig some more in daylight.

It may very well have the double head. It's not dropping any characters at
1200. I am surprised. That's 4x the expected speed!
Here is another sighting of a Silent 703 working at 1200 bauds:

Says the author in the comments: "My Silent 700 came with a manual. So I
went by that. I was pleasantly surprised that my Silent 700 had the "high
speed option"."
So there was a high-speed option for the Silent 703 apparently?

Wow. I used to use one of those for BBSing back in the day, and it required nulls ?

Looks like it. I haven't found anything yet on the 703 high-speed
version, but it's probably similar to the 707/1200 version. The one
shown here has a copyright date of 1986, so getting late in the game
there. That is PN 2545996-0001 and also has an external serial port
not found on earlier 707s, I think.
https://www.reddit.com/r/retrobattlestations/comments/p4atq2/ti_silent_7001…
I will try to ask somebody who worked at the Temple plant about it,
though.
9:44 a.m.
I hadn't known about 1200 bps Silent 700s. I just found a TI Silent
700/1200 on eBay and it is now on its way to me. If I can figure out if/how
it can toggle between 300 and 1200 bps, I'll let you know.
Meanwhile, I can tell you that a manual I have for a model 703 says that
configuration switch 4 is "not yet used". 1 & 2 are for parity, 3 is for
print width (80/132 columns). Maybe switch 4 toggles between 300 and 1200.
If you lift the smoky gray cover, you'll not only gain access to the roll of
paper but also, just above the keyboard, an expansion slot on the left-hand
side and the four DIP switches just to the right of the expansion slot. The
DIP switches are found below a small rectangular cutout in the terminal's
plastic case.
On a model 703 I have there is a label under the paper roll that tells what
the 3 working DIP switches do and tells some of the CMD key sequences that
can be use on models 703, 707, and 709. Apparently the same label was used
for all three basic models. But maybe a unit with a 1200 bps option has a
label that lists a function for DIP switch 4 or a CMD key sequence for
setting communications speed.
Another possibility is the auto-access cartridge that can go in the
expansion slot. The 700/1200 I have on the way to me includes an
auto-access cartridge. Maybe it allows choosing between 300 and 1200 bps?
If you have an auto-access cartridge in your terminal, try some of the
commands for it that are listed on the quick reference card
http://www.bitsavers.org/pdf/ti/terminal/silent_700/2310610-0001_Silent_700_
Auto-Access_Cartridge_Quick_Reference_Card.pdf .
If you figure out how to toggle between 300 and 1200 bps, please share the
trick.
10:06 a.m.
I should have looked closer at the photos of the Silent 700/1200 I just
bought. There's a very clear auction photo that shows DIP switch 4 does
switch between "300 baud" and "1200 baud". Maybe it's the same
for Marc's
1200 bps model 703.

On my 703 the label says switch 4 unused, and it does nothing when I try it.

Yes, I tried switch #4 and that did not do it. I opened it up, no other obvious jumpers.
The processor doesn?t even say TMS 7041, it?s a custom numbered part. Not that I am
complaining, I am fine with my blazing fast gamer?s TI 703 with overdrive. I?m just
surprised they did not label it anywhere on the machine or even change the product naming.
Like TI 703 Turbo or something!

I just checked my 3 703's... all are switch 4 unused and functioning at 300 baud. If
you would like to trade one in order to have the classic 300 baud experience...
