Re: gEDA-user: datasheet

[Patrick Dupre <pd520@xxxxxxxxxx>]

Hello,

Thank you very much for the information.

Yes I would be interested by the pinout.
It is probably different from the TTL. By the way, I already try to
replace a DTL by a TTL after pin modification, but the chip warms up
and seems to oscilate. Any, with the pinout, I can first check it is
faulty.

Best Regards.
