They are missing then. The 8E had a cover as did the 8l and I think
the 8I.

Compare to a real top for vent slots as needed.

<P.S. I'd like to thank Allison for relating the story of bringing up her

My pleasure. I'm still working on mine to get it talking over the serial
(I havent tried and I have to make a RS232 cable).

Still they are a really fun machine and gobs of fun to hack new interfaces
only. Omnibus 8s were the most hacked of the series as the bus made them
easy to interface to and DEC make no secret of what is needed to do it.
add to that with 8kw or more of core it's a machine that can do serious
work if one chooses.
