Malcolm's Amateur Radio page ...

For no especially sound reason, I have got a copy of the application notes for the Curtis 8044ABM keyer chip here. The original PostScript file weighs in at 1.23 Mbyte or if you want something smaller then here is it ZIPed at just 215kbyte. Some may not find the PostScript form convenient so I have converted it into PDF at two resolutions - the smaller (116kbyte) file is suitable for viewing on-screen and the larger (476kbyte) file should have enough resolution for printing onto paper.

And the rest is an old and disorganised set of bookmarks:
