David C. Wiens

I specialize in software and hardware design for small embedded systems. My current favourite microcontroller is the ultra-low-power MSP430 from Texas Instruments. When I get some "spare time" I will update this web page to show some of the products I have developed for my clients, and for myself.

In the 1980's I mostly used the Motorola 6809 microprocessor. Some of you may remember my Sardis Technologies ST-2900 computer boards (sold mostly in kit form), and the "no halt" DMC floppy disk controller for the Radio Shack Color Computer.

NOTE -- September 8, 2016 marked the 40th anniversary of the first meeting of the West Coast Computer Society (WCCS) -- and I was there! The WCCS was the first microcomputer club in the Vancouver, BC (Canada) area, and met until 1990.

I exhibited at the Vintage Computer Festival Pacific Northwest 2018 on February 10th and 11th, 2018.

com Thanks.
(I'm hoping that showing my e-mail address this way will reduce the amount of spam that I receive.)

(Just to verify that you found the right person, before 1998 my address was 2261 East 11th Ave., Vancouver, BC V5N 1Z7, and my phone number was 604-255-4485.)
