You do not need the keyboard to use the 7854 for routine storage and waveform
measurements. When it boots up, its basic functions work like any other 78xx or
79xx series mainframe.
If you want the complete experience to go with the keyboard, it may be worth
picking up a 7B87 timebase which replaces the 7B80 and allows pretrigger
acquisitions up to the admittedly slow maximum sample rate of the 7854.
The 7D15 should work fine in a 7854. I know mine does. The 7B71 timebase works
in the 7854 with some minor exceptions that you are unlikely to encounter which
are discussed on page 2-24 and 2-25 of the operating manual.
As I said in my other post, I would start by powering the mainframe up without
any plug-ins. It should execute a power on self test and report any errors. As
others mentioned, checking the line voltage setting and fuses and doing a basic
visual inspection with the two covers removed is worth doing as well.

Just purchased a 7854 off the Bay of E yesterday. Obviously, haven't
received it yet. Pictures from the auction do not show it powered up,
but the description says used but signs ofcosmetic wear, but according
to the seller it is operational.
Not ever having had a scope of such complexity before, anything I need
to look out for when powering it up?
Doesn't come with a keyboard, so I'll be looking for one of those.
Preferably one that isn't more thanI paid for the scope. ;-)
Comes with a 7D15 counter/timer and what looks like a 7B71 time base
(hard to tell exactly, picture is kinda fuzzy).

David and everybody that's contributed,
Thanks for all the hints and tips. Can't wait to get this thing up on the bench. ;-)
Hard part is getting it past my wife to the bench.
