What is it ?
I came across this partially built board:
Not sure what it is. It might be a keyer board (noticed labels DI and DA on the right side) - also has a spot for a regulator chip a the top. With pin 8 ID'd as ground it is probably an 8 pin PIC based keyer. Possibly from FAR Circuits ? That blue silk screen looks familiar as well as the single sided board. I looked on this page:
https://farcircuits.net/Keyers.html
But nothing looks familiar, it may be a discontinued board. I didn't see anything in my notebooks about this board or even a FAR order (shame on me). Possibly I have some docs from FAR - I remember a heavy paper envelope with boards in it - another hunt is required !
