[GreenKeys] Speed Converters

[Ron Kolarik]

Mainline UT-4, and I have the circuit board in the last rescue pile.
No docs but all the chips are there and it's built into a chassis with
some other logic......yours for shipping if you want it.  You'll need
to replace the PROMs with either other PROMs or maybe an
EPROM to make it easier to change.....no docs, not sure what will
work.

Hi Y'all
Back around 1980 ASCII  to baudot (and vica versa) speed converters were
common. Some were built into the FSK converter and some were seperate. Does
anyone have one of the  seperate units either homebrew or commercial or a
construction article about the same.

Thanks,
