There is an auction for a Heathkit H-11 computer DEC H11A LSI-11. The
case doesn't look like a Heathkit H11. The description says it was
purchased as a kit from DEC back in the day.

Does anyone know something about this model. The pictures show that
this is not the typical H11 case and the front panel appears to be
hacked/mod. Were the internals moved to a different case or is it
possible that DEC had a different version of the H11?

That front panel is a standard blank "filler" panel used on DEC H960
racks in the late PDP-8 and early PDP-11 era.

What I suspect happened here was the owner got ahold of one of those
panels and drilled/cut it to support the switches and LEDs, and
transplanted them (along with the nameplate) to this panel. This would
also explain why the labels are scraps of paper taped to the panel.

DEC was not a "kit" company...they were far too "corporate" for that.
Even buying completed hardware from DEC as an individual was often
difficult.

That machine made this discussion list a while ago too... not sure if
it is the same seller or if it changed hands and is then being sold again.

It continues to look pretty grubby to me... the photos of the inside
show a lot of rust and other discoloration on the circuit boards...
not a good sign.

In addition to the homebrew front panel, the chassis is not Heathkit
either. It really looks like a totally homebrew job... with maybe some
Heathkit parts used in the process. For sure it is not an authentic H11
"system".

Ahh ok, I hadn't noticed that the chassis wasn't Heath.

The weird thing is that the seller now seems to think that anything
DEC- or PDP-related is "Heathkit".
