WristApps for the Timex Datalink 150

WristApps - Applications that can be downloaded and run by a Timex Datalink Watch.

I enjoy gadgets, and I love my Timex Datalink. In addition to being able to download phone numbers, lists, schedules and alarms from a PC, it has a Motorola 6805 microprocessor and 1K of user memory for custom applications. Coding for it reminds me of the good old days: programming my father's KIM-1 in 6502 assembly. In many ways, these two computers are similar in their architecture and their limitations.
Here are some Wristapps I wrote to extend the functionality of the Datalink 150 and 150s.

Three 12 digit numeric pads for on-the-fly recording of phone numbers, reservation numbers, game scores, and other numeric information. Now you can enter information into the watch while you are away from your PC.
24-hour chronometer with split mode, and an integrated self-recycling countdown timer with alarm.
Alarm Enhancer (allows user to create weekly/weekday only/weekend only alarms).
Bugfix for the Timex ROM hourly chime set bug.

Txtpad
Txtpad is a special version of Numpad for those who need move advanced entry capabilities.

Eight 20-digit memo-fields (12 numbers+8 characters), can be used to enter a wider range of information, including addresses and names.
No chronometer or timer included.
Numpad's Alarm Enhancer and ROM Bugfix are included.
Download Txtpad version 0.9 (Jan. 12, 1998)

In response to numerous requests, Txtpad 0.91 is very different: Only 3 Memos, but it provides other options, such as a Chronometer and the Chime Control feature.

For some people less is more... After many requests, here's Nopad, which has all the features of Numpad, except for the memo fields. There is no documentation with this version. The documentation can be found in the main Numpad distribution, above.
