Mockup of screen w/ file handling 

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:

(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

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.

Details of the currently shipping version:

If you have a Palm III you need to be running at least PalmOS 3.3, which is available free to Palm III,IIIx, V, IBM WorkPad 20x, 30x, C3 users at PalmOS 3.3 Upgrade

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.

* 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
