You obviously have NO clue what you're talking about.
i was there in '76, and those had already been out for about a year.

Everyone knows that KO flicked the switch on the first VAX-11/780
off the production lines on 25-OCT-1977. There were no VAXes
before then (and the VAX-11/780 was not luggable by any human
definition).
If Bob Supnik says there was no luggable VAX on his watch, then
that's more than good enough for me. If there were luggable VAXes
before his watch, one has to wonder why DEC made such a hoopla
about the MicroVAX II (mid 1980s, distinctly non-luggable, although
it could make a comfortable seat if you were tired).
I know der Mouse knows all this, but just in case someone trips over
this thread 20 years from now, I thought I'd throw in a few easily
verifiable facts for them check out. Rumours start way too easily.

There must be something I'm missing here. You said that the VAXstation
(I'd guess people are taking about the 3100 series here, not the larger
versions that are on wheels) isn't a luggable, but a rainbow is. The
DEC Rainbow I've got at home is bigger than a VAXstation 3100, and
unlike the Osborne 1 and Exec that I've got, does not have a built-in
monitor, or detachable/attachable keyboard. Or, do you mean a form
factor that's not similar to the Osborne 1?
For that matter, are you saying that 30 years ago, in 1978, that Digital
was able to produce a VAX CPU, memory, some sort of storage, and a
monitor that would physically fit into a case the size of the Osborne
1, and which drew a small enough amount of power to comfortably run off
a single 15A, 120V outlet?
My "best guess" is that perhaps you are referring to the PDT series of
luggable PDP-11 systems that DEC produced. However, I don't know when
those were produced, and it could well have been less than 30 years
ago.

You have Osbornes too? Does your O-1 have the DD and screen-pac upgrades? I
saw a lot of those machines, there being a local club and me having my shop
in the building of the dealer who was selling them. I liked the exec pretty
much, excepting the single-sided drives, but never cared for the O-1 as
much, mostly because of that 52-column screen.
Remembering how after installing the screen-pac upgrade for folks I could
actually read those characters when it was set to 104 columns...! Not
something I think I could do these days, though they do have a pretty sharp
screen, there.

I completely agree. I managed two 11/750s between 1985 and 1994, and I still
have one of those two (S/N BT00000354). There is nothing FEPish, but
there is something like an ODT console program. You can examine registers
with it, but I only ever did that once (debugging a problem with a
second Unibus interface - L0010, IIRC). Mostly, folks just install
a boot ROM to match the boot device and twist the A-D selector
switch to the correct position and press "reset". We had three ROMs
in ours - the default console TU58 boot (position "D"), MSCP ("A" in
our
case), and a "DR" boot ROM for either an RM03 (or RM05) on the MASSBUS or
for our SI9900 w/SMD disk that I talk about here from time to time
(emulated dual RM03 plus an oversized RM05).
The 11/730 (and 11/725) has an on-board FEP - an 8085. You talk to
it much in the same way as you do to the LSI-11 in an 11/780, except
its console medium is TU58 tape, not RX01 disk. Syntactically, though,
I believe it's similar (I know the KA730 well, but not the KA780).

Perhaps someone is confusing the 11/750 with some model of PDP-10? I
know that there was a PDP-8/i-based I/O subsystem for one of the -10s.
I've also seen an -8/a in the block diagram for a peripheral for some later
model of -10 (does a "DX10" ring a bell to anyone?) Most of the -10s I've
seen personally, have an -11 for an FEP, but I am not an exhaustive
authority on 36-bit hardware, especially not, say, a KA-10. I've stood
in front of a few KS-10s and perhaps a KL-10.

Indeed, the 730 CFE (Console Front End or FEP) was very much like the 780
- the commands were similar and the 730 even used indirect command files for
functions like booting and power up loading of microcode. All the
microstore on the 730 was RAM; the only ROM was a little EPROM that booted
the 8085 operating system from the console TU58. Everything else - all the
CPU microcode, the microcode for the IDC (integrated disk controller) the
FPA microcode, and VMB - were all loaded from the TU58. Although the 8085
operating system was some custom thing DEC wrote themselves, the TU58s used
an RT11 file system (again, just like the 780) and you could easily
manipulate them with EXCHANGE or FILEX.
The bad news was that TU58s are really, really, slow. With all the
microcode and indirect files that had to be read from the TU58, your 730
could easily take ten minutes from power on to the point where VMB was even
ready to start thinking about loading VMS. When working on one, you want to
do everything you can to avoid turning off the CPU box power:-)
Because everything about the KA730 microcode was "soft", it's fairly easy
to change the CPU microcode, update the console TU58 and reboot to change
the CPU behavior. I believe DEC even sold a set of microprogramming tools
for the 730, but I've never seen them and I don't know what's become of them
today.

In one of the DEC Technical Journals, there's a description of the
work that was done to emulate a MicroVAX II before the hardware
was ready. They used a VAX-11/730 and reprogrammed it to be
a MicroVAX II (minus the bits that wouldn't fit, like some of the
floating point IIRC). It was good enough that they were confident
enough to redefine which instructions would not need to be
entirely done in hardware.
Reading between the lines, the microcode development stuff
was already "stale" by then. Finding it now would be a
challenge I would think!

Using the stock console tapes from DEC, that was absolutely true. One of
the scripts I wrote a while back, built a load-order optimized console tape.
I think the 8085 must cache the directory, since the tape doesn't seek back
to the directory blocks between each file. With the files in the right order,
the file transfer time doesn't change, but the file-to-file time is just about
nil (I think there may be one seek from end-to-end because of how many files
there are to read and the block interleave on the tape).

I used to have (and may still have somewhere) the VAX-11/780
microcode manuals - we'd planned to add some extra instructions to
speed up an application so I investigated this. In the end we just
waited and got a faster VAX :-)
