Easy upgrade to a 34 or 34A, just slip in a M7265 and 66 or a M8265 and 66.
Any cpu in any box will take the KY11-LA or LB.

repair easily, or what to learn (or teach) the internals of a real CPU.

It's more than _I_ would want to pay for a bare 11/04 in unknown
condition.

IIRC the keypad frontpanel is an option (the 'Programmer's Panel'), as I
believe it is on the 11/34. Every 11/34 I've seen has had the keypad,
every 11/04 hasn't, but that's hardly a representative sample.

It's a fine RT-11 box, but so is an 11/23 (which is much more common
and about the same physical size). If you had some Unibus peripherals you wanted to play with, you could drop a couple
in there, but ISTR
there's a small number of empty slots after you install the CPU, memory,
and a console.
I'm not saying it's an terrible machine - I have one myself. There are
I nearly got one, but eneded up taking na 11/34 instead. I don't really
regret that choice.
The 111/04 and 11/34 are pretty similar. Same backplane, mounting box
(There are 2, 5,.25" and 10.5", but either can be used for either
machine),
memory, PSU (for a particular box), front panel etc. The 11/04 is a
simgle hex-height board for the CPU, the 11/34 is 2 boards.
_Somewhere_ O have an 11/04/34 user manual were references to the 11/09
and 11/39 have clearly been whited out before the manual was
duplicated... In fact I think one of the line drawings has '11/39' on it.
