That's correct. Now, the interesting thing is that according to pinout
charts, the keyboard cables are the same (clock, data, not used, ground,
+5). However, the keyboards are not compatible. Does anyone know what
the difference is?

As for assemblers for the 64 if you want to do on-the-fly assembly Supermon is
cool, there is a version of it in just about all the popular super utility
cartridges (i.e. Super Snapshot, Final Cartridge, etc.)
As far as more quality (disk based) assemblers I would go with Lew Lasher's
Editor Assembler (circa 1985, hard to find, freeware, and nice) or Merlin
(especially Merlin 128 for the Commodore 128). Both are good ones to learn
with. There are other like Buddy, PAL, Bettwe Working, etc. but those use the
BASIC interpreter to code (line numbers and all.)

I think the person added it himself.
There are four flavors of the Commodore 64.
Commodore 64 - The original unit, roundy brownish-grey case dk. brown
keyboard, a good machine.
Commodore 64c - The updated (low-profile lt.cream case, white keys) cost
reduced model unlike other reponses no voices were removed. The story is
Commodore did a 'bug fix' on the sound chip that affected games that utilized
a perceived flaw on the sound chip that made digitized sound playback easy, on
the 64c you can barely hear the digitized segments.
Commodore SX-64 - the Commodore 64 in a luggable all-in-one unit included 64,
5" color display, built-in 1541 disk drive and audio speaker. Pretty cool,
used original C64 chips though Commodore altered the ROMs to better support
the built in drive at the sacrifice of cassette support (and compatibility
with some programs and hardware that required it.)
Commodore-128 - One of the facets of the Commodore 128 is the C64 mode, the
chips reflect the older 64 and is 99.94% perfect in emulation except for one
memory location which can bump the computer into 2mgz mode thereby messing up
the display provided by the 1mghz 40 column display chip. :/ Some earlier
games inadvertanly activate this mode.
If I wanted to do only 64 stuff the original grey 64 is the one to get.

Depends on the PET 2001, the earlier ones had a smallish calculator type
keyboard with an integeral datasette unit. Newer models had a full sized
keyboard and no built-in datasette.
All of the 2001 series had 9"display, earlier ones displaying whitish-blue the
rest gool 'ol green phosphor.
The original BASIC (Powers up with *** COMMODORE BASIC ***) has neumerous bugs
and lacked disk support the upgrade BASIC (### COMMODORE BASIC ###) had many
bug fixes and is very close to 64 BASIC in operation and syntax.
There are two motherboards associated with the 2001 the 8k static ram
motherboard (only in original PETs) which was limited to 8k ram and used MOS
RAMs (Which they soon stopped producing, they just weren't good at memory
chips) and the later Dynamic RAM boards which were expandible to 32k.

as you might guess, the VT220 w/o keyboard is spoken for. The others
still need homes though.

Ok the 10th is right around the corner so I'll post this one last time
before It goes with the scrap.
Visual 102 terminal with keyboard - complete and working, good shape
DEC VT 100 without keyboard - working as far as I can tell and good
shape
DEC VT 220 without keyboard - working again as far as I can tell, good
shape.
These are free except shipping. I need a firm answer for a home by
Firday and then a money order for the estimated shipping by the 20th or
they go to terminal heaven. hate to do this as I'm sure someone can use
them.
I still have the last of the working HP 700/44's with keybaord and
lookig like brand new for $15 plus shippping too, but I have the room to
put it back for a while and maybe even use it later.

I intended a very gentle guiding message for Max, and in no
way said anything about censorship except self-restraint in
the form of editing recommendations (endlessly requoted
messages with one-liner replies drive me up a wall).
I gave general advice to search the net before posting, as
opposed to treating the mailing list as a magic oracle
that answers all your questions. Save the list for the
truly obscure questions, not the stuff that's on hundreds
of web pages.

I don't think Jim's list is quite correct. For a start, there were lots of
2001 PETs with 9" screen and the graphics keyboard, without the
cassette-beside-the-keyboard. I've got one here. And the /B and /N series
were called 3000's not 2001 everywhere except the USA. The 12" versions
didn't appear in the UK until later. According to my (USA) manual, the
2001/B (aka 3000 here) was a 9" screen too. IIRC, the 4000 was the first
with a 12" screen, at least in the UK (USA might easily be different, of
course), and that's borne out by my manuals. The 12" screen version was
eventually called the 8000 series here, and had different firmware (and up
to 96K RAM I think, bank-switched).
One of the differences between the business and home versions (apart from
graphics symbols on the keytops) was whether the machine powered up in
upper- or lower-case.

My 2001-8K is white phosphor. The full-size-keyboard ones were green.

On the later models, that's TAPE#1 and the TAPE#2 is an internal connector.

Well, they do, sort-of, but a bug in the IEEE routines prevents it from
working with anything other than a printer. There were a few other bugs
as well, and the upgrade ROMs themselves were replaced later.

There was a very-short-lived BASIC-2, and BASIC-3 (more-or-less the upgrade
ROM set) was around for a while before 4. 4 has extra commands for the
disk, instead of having to use the generic IEEE channel commands, but
otherwise it's almost the same as 3.
Only the original ROMs start up with ***; all of the later ones used ###.

All those POKEs are ROM-version-dependent.
