presents DLPilot

DLPilot emulates the Tandy TPDD drive on PalmOS PDAs that have a serial port. So far it has been tested on the following serial Palms:

Palm Vx
Palm III
Palm IIIxe
Palm VIIx
Palm M505
Palm Tungsten T3
Palm Tungsten W
Handspring Treo 90
Handspring Visor Prism
Handera 330

w/ PalmOS must be 3.3 or greater
For those who don't know what a TPDD is: the TRS-80/Tandy TPDD ( Tandy Portable Disk Drive ) is a battery powered, ultra-quiet portable floppy disk drive that connects to the serial port of the TRS-80 Model 100, Tandy 102, NEC 8201a, NEC 8300, and other devices. Lots of Model 100 vintage laptop users have this drive, and some don't. They aren't plentiful anymore, and the old ones are breaking (I mean the drives, not the users!). So I created DLPilot to emulate these old drives.
I've been asked to make early copies available, so If you are willing to keep up with the alpha releases then you can buy what I have for $25.
When the final version is released it will cost $30. For those who buy before release, the upgrade fee will be only $5.

Send email to with your name and address if you would like to order a copy, and I will send you the invoice as a PDF file. I accept Paypal or check drawn on U.S. bank in U.S. funds.

In 6 months after the full release the source code will be released under the GPL License. I may release it for individual use for those that need it under a different license before then; ask me. In any event, I ask that you not redistribute the software before that point, so that I have a chance to sell some copies.

Details of the currently shipping version:

For vintage PCs that connect to floppy via a controller instead of a serial cable, check out Eric J. Rothfus's "Semi-Virtual Disk", a flash based floppy disk emulator which plugs directly into your vintage machine's floppy controller. Disk images are transferred to it from your PC via Serial cable. It has many other features too.

If you want to pay by PayPal* my address is
If you are in California, please add 7.25% to cover tax.
If you simply do not foresee having the money to afford DLPilot, let me know, we can probably work something out.

* PayPal charges me fees for using PayPal. If you want to go the extra mile (not required, I won't even give you funny looks if you don't) and pay my fees, here is the formula:
        Let x be the actual price of the goods + shipping cost
        Let y be the final price you ask the buyer to send you via
        Paypal standard rate fees are y * .029 + .30
        Then y - x should be equal to the Paypal fee.
        y - x = y * .029 + .30
        Solving for y gives
        y - y *.029 = x + .30
        y ( 1 - .029) = x + .30
        y = (x + .30) / (.971)

So for $25 that would be $26.06
