Subject: Hex Keypad
On the subject of Blinken lights and toggle switches, I have had
difficulties finding decent mechanical keyswitches to use for projects.
Essentially, I need to make a hex keypad, with a couple of extra
function keys. I know that now we would simply get a membrane rubber
thing made up, but once upon a time, I would purchase 20 mechanical
switches, and solder them to veroboard.
Sadly, I can't find a source of these switches any more.....
Same applies to ACSII keyboards - I am fully aware that I could get a PC
keyboard and a microcontroller and have ASCI out - but that is 'yet
another pc keyboard'
Let me know off-list if you can't find what you need; I've got several boxes
full of old keyboards etc. (including an APL keyboard, although I can't
recall what that's from ).
