Which HP 264x terminals used 8008 cpus? I know that the 2640 and 2644 did -
but did the 2648 or any others in the series also use it? What is the HP p/n
for the 8008 in this application?

The 02640-60008 processor board in my 2640B has an 8008 CPU. Looks
like standard Intel markings.
The 02640-60209 processor board in my 2645A has an 8080 CPU. It is
marked as 1820-1701 (c) AMD. Looks about the same as this 02640-60256
board: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5145936933
The 02640-60249 processor board in my 2647F has an 8085 CPU. Looks
like standard Intel markings, D8086AH-2. There is also a Z80 CPU on
the 02640-69223 floppy controller board.
Does anyone else have a 2647F? I have two floppy drives for mine, but
no program disks. It would be nice to find a copy of the BASIC disk.

I took the CPU card out of one of my HP 2648s and it also has an AMD part
with a HP part number (1820-1701). I had guessed that it was a 8080. I took
some pictures of the card and CPU but I borrowed someone else's camera and
the pictures were LOUSY. IIRC the name on the card was simply "Processor"
or maybe "CPU" with nothing to indicate what kind of CPU it was. I'll
bring the card home next time and try to get some decent pictures.
There's also a HP 2647 at the warehouse. IIRC There's no drives of any
type on it. I'll try to open it up and see what kind of CPU is in it.

I've got the disks. I can provide Teledisk images. If that won't work
and you need physical floppies, I can probably arrange that. But I hope
you're not in a hurry, because I probably won't be able to do either
until January.

As far as I know only the 2640 and 2644 used the 8008.
Some HP p/n from those Terminals:
1820-1219 TR 1602 B USART
1820-1221 D 8008-1
1820-1288 MMH 0026 CL two phase MOS Clock Driver
1816-0612 MMI : Char. Gen. Roman upCase [24] Terminal 2644 A
1816-0613 MMI : Char. Gen. Roman loCase [24] Terminal 2644 A
Firmware ROMs
1818-0157 EA 4900 masked Terminal 2644A
1818-0158 EA 4900 masked Terminal 2644A
1818-0159 EA 4900 masked Terminal 2644A
1818-0160 EA 4900 masked Terminal 2644A
1818-0161 EA 4900 masked Terminal 2644A
1818-0162 EA 4900 masked Terminal 2644A
1818-0176 EA 4900 masked Terminal 2644A
Those numbers come from my own terminals. Other 2644 may have newer
firmware ROMs with other partnumbers. There were also different
interface cards with maybe different USARTs.
Also I don't know, if for example ROMs of same types and maskrevisions
but different manufacturers (EA, Mostek, MMI) had different partnumbers.
