Same question. I can update your WP34S using any version available on Sourceforge.

My preference though is for Bit's versions, described here: https://www.hpmuseum.org/forum/thread-2433.html

I don't have any Windows machines either, nor HP's programmer cable. I used a Mac running Ubuntu Linux and Wine with a custom flash programming box I built, adapted from Jebem's instructions, all of which is described here: https://www.hpmuseum.org/forum/thread-25...25975.html

Since then I added a timer circuit to make the Tx / Rx LEDs more noticeable, a simple task that nevertheless doubled the board space.

None of this was easy...

Version history may be found here, although it may not be the best or most comprehensive source: https://www.hpmuseum.org/forum/thread-2476-page-15.html
