The last thing I heard about TDOCK was from Ken: --------------------------------------------------------------------------------- On Mon, 07 Dec 2015 07:36:15 -0800, Ken Pettit wrote:
The goals of TDock: 1. Provide an HDMI LCD video interface for Model T (a DVI replacement). 2. It should work with M100, T102, T200 and PC8201. 3. Provide a TPDD client to USB Thumb drives or SD cards (NADSBox substitute). 4. Provide an interface capable of supporting networking. 5. Provide an interface for printing to modern printers. 6. While not a goal, it also provides 13 I/O pins (well 11 I/O and 2 input only) on the pass-thru LPT port when not connected to a printer. The implementation in the picture is a daughter card for the Raspberry Pi 2 B (a "Pi Hat"). It connects with the Model T parallel port for primary communication of video data, but also has an RS-232 port (and a BCR port). It also has a "pass-through" LPT connector where your old LPT printer can be connected. Making TDock a Pi Hat was the simplest and cheapest approach, though it is not very portable and has the requirement of booting / shutting down Linux. My other ideas involved simple microcontrollers or FPGAs to provide HDMI / VGA. They would have been more portable, but also more expensive. The general theme on this list always seems to be "cheap" (though I prefer the word "inexpensive"), so I decided to give up portablily in favor of lower cost.

And I am able to connect with and program the CPLD. It still remains to be tested, but getting the PCB is a big step. Photo here: http://www.kenpettit.com/images/TDock.JPG (the USB connector is for power only). Ken --------------------------------------------------------------------------------- These 2 messages say it all, I would think. A TPDD emulator based on modern technology, and the basis is the Raspberry Pi 2B.

I know that Ken Pettit was working on a project named TDock. I was wondering where I can more information or some kind of picture of TDock I think Ken was mentioning that it will have a USB port and other plugs in. But I do not remember all the details. If anyone on the M100 list can give more of what TDock does. Please do so. Duane A.
