Me too, but I don't know Japanese! <g>

Mine too. I think it is officially called a 11/730Z 10.5"box? b/p standing vertical? PSU on
right? Whoa, that must be something
different in a VAX 11/730.
Look at this URL for a picture of my 730:

It's a Japaneese page, but there's some English text *and* a photo of my
730.
I wish I could get Japanese support working for Netscape 4.03 under X on my Solaris box. :-( I saw the picture. I have never
seen that model
of 11/730 up close. It looks kind of like a miniature 11/750. I would
That is a good way to describe it. It's the same height as the 750 setting
next to it, only narrow like the cabinets that RL's, TU80s, etc. can reside
in.
suppose that there is a BA-11 inside with a 11/730
backplane and some
DD-11DK's, no? If you forego the IDC for Unibus disks, yours looks like
Yes. Only one DD11-DK is called out (see earlier mention of this fact in
the first msg of this thread.)
a nicer design. Perhaps that's what they did for
later units. The
A couple of dates inside the unit place mine around middle of 1984.
BTW I'm still looking for a front and back door for this machine. Now that
anybody can see a picture in that Japanese DEC site, that's the box I'm
refering to.
cabling on the older 11/730's is a nightmare to
install (a co-worker
did the one I have), but once in place, it's OK. I'm guessing that the
in-cabinet cabling for your 11/730 is like the 11/24 or 8200 - a pile
of cables snaking through some strain relief bars, ending in a wall of
Yes, I even have a 11/24 setting nearby to compare it with too. Too bad I
cannot keep either the 750 or /24. No room, dang it! BTW: the /24's cabinet
is the same height and width as the 750.
I/O plates. Can you put any additional stuff in that
cabinet, or is
it all cable run?
I think I can install another unit like an RL or tape drive. Have to check
depth first. That's the major part of my idea to try to make a working
system in the smallest footprint. I know the TS03 tape unit will fit since
it's not too deep. The various controller modules for the TS11 drive
control would fit into the DD11-DK backplane.
Hmmm, if I can find a SCSI module or something I wonder if a more modern
SCSI hard drive and tape unit (as in the types used in the PC world) could
be installed??? How about a TK50 tape and an RD-something HDD? Anything
w/larger capacity than TK50 in that physical size? (I must find a good
primer for the more modern and smaller DEC HDD and tape units. Any pointers?)
Anyway, that arrangement would be small enough to mount into a 5.25" high
19" rack drawer with a PSU and fit inside the cabinet nicely underneath the
730's BA11 crate. This would make a single cabinet machine with the
smallest footprint possible! Yeah! I'm hep!
Anybody have any ideas?

I recall seeing mentioned somewhere a URL from Finland that has info and
archives for MicroVAXen. Anybody know of that and could pass the URL on to
me (and the list)?
Thanks for the help!
