Hi,
Does anyone know the part designation for the keyboard on an HP2648A?
I've looked through the manual (unfortunately not OCRed so a visual
inspection of all pages is required) but didn't see a part number for
the keyboard itself.
Anyone have one of these?

I have three 2648A terminals... one has the keyboard that has tape drive
controls on it. Unfortunately the HP tag is gone from the bottom of that
keyboard. The other two terminals have keyboards labled 02640-60180, which
do not have the tape controls on them. Given that all three terminals have
dual tape drives.... I'm betting that I got the wrong keyboards when I got
the terminals. Someone wanna trade 264x keyboards without tape controls for
ones that do? :)

Wow... 3 of 'em :-).
How often do you fire them up? They used to have some of these in
the terminal room at udel.edu and were the first raster graphics
terminals I remember seeing, around 1980.
I'm trying to secure my first unit from Boise -- I'll probably be able
to pick it up next weekend. I got the user manual from bitsavers and
I was surprised to see how many options it had, with a "main frame"
and all that. Besides the dual tape drive option, do you have any
other options on them? Recently some ROMs were offered on ebay but
god knows what they actually provided (presumably they provided
additional graphical character sets or something like that).

Got a few 262x
terminals too. The 262x and 264x are pretty nice terminals
really.

the last month or two excepted..... about
twice a week. They're kinda
essential to boot my HP2000 systems. Also many of the HP off-line utilities
get rather irked of you don't have an HP terminal on them.

When I was
refurbishing my first 2648A, I spent a lot of time going through
the manual from bitsavers. I was completely shocked at the features &
functionality in it. I'm familiar with quite a lot of terminals and never
saw one with so many features. It really is a little computer. As I recall
(very foggy memory), the option roms gave you additional character sets, the
ability to make your own characters... and I think there was a ram upgrade
for graphic memory. There were also option cards for additional serial
ports, HPIB ports, etc (I luckily have those).
Well, when you pick yours up, let me know if they have any extra keyboards
that have the tape controls in the center :> I haven't looked at my HP stuff
in a while, but I do recall that my 2648A's were completely stuffed with
option cards.
By the way... if your terminal needs parts.... Of the three 2648's I have,
one has been restored to perfect condition. Another is half-restored, using
some parts from the third. If your terminal needs parts, you're welcome to
the leftover parts from my 3rd donor system.
Best regards,

From the "264X Composite Service Manual" (HP
02640-90170), there are three
2648A keyboard assemblies listed:
- 02648-60001
- 02648-60005
- 02648-60006
01 is listed for use with "olive black terminals," 05 is listed for "cocoa
brown terminals," and 06 is listed the same as 05, but with "RFI opt
-017."
I believe the RFI option added a short ground strap, terminating in a
female quarter-inch spade lug, at the keyboard connector.

02640-60180 is listed as the 2640B keyboard assembly.

Indeed so.
