I can take a few pictures this weekend. Just got to find a good host
for the pictures. My web space is near its limit. Any suggestions?
The rack that holds the TU81+ tape drive has underneath the space
for an RA8x drive. I had it that way, but one year ago I removed the
RA82 and installed two of these SA72's. It is intended to be hooked
up to the VAX-11/750, but the VAX has PSU "issues".
I am pretty sure I have two more SA72 without drives, but contains
the PSU is in it IIRC. However, even without any drives installed
these things are good if you want to hurt your back :-/ So, shipping
one is not an option.
I even have a plate that is mounted in the rack ...
If you wonder how the SA72 is mounted in a rack, given that its
width is just half the width of the rack, well it just "hangs" on one side!
The SA72 at the right side hangs on a plate mounted in the rack at
the right side, and the SA72 at the left ... on a plate at the left side.
Even such a plate is good for a few kilos on the scales!

You may very well be right Johnny.
I was just dumping my grey memory cells :-) I did not check the HW.
Isn't the SA72 a small slim long metal box with a power supply in the
middle and room for two RA[79]x drive at both ends? At the front side
at the top is a connector for the small front panel. The width of the front
is 0.5 of 19" so that two of these fit next to each other in a 19" rack.
If that's way off, I'd have to check what I actually have ...
- Henk.
I have a small stack of single-sided disks that I need to image, and didn't realize
that they are 18 sector with 0-16 256 bytes and 17 128 bytes, so Imagedisk won't work.
What is the preferred container format? Looks like the Australian museum uses .td0
I just started using Google Adwords and I?m trying to figure out how they charge. I just finished the free first time allotment of $75, now I have to add more money.
Does anyone have any experience with this ?
Also I?m looking into the Yahoo/Bing adcenter.microsoft.com. They don?t seem to offer a free first time allotment. Does anyone know of any way to get a free startup allotment ?

Hello,
I was referred by a member, Peter Wallace.
We are trying to recover some programs from 9-track backup tapes.
I have a working 92185 drive, and had salvaged a SCSI - Pertec formatted
interface
converter off the back of a Cipher 990 drive at work. The Cipher 990
was total
crap, hardly ever worked. The SCSI converter actually worked for a while, I
was able to read a few blocks of tape (without a proper program to
handle the
format, I just did stuff like
sudo cat /dev/st0
on a linux system, and got info that looked like the first couple
records off a tape.
Then, the converter died, it stopped passing its internal self test.
But, I had proved the
92185 drive is OK. So, now I'm looking for a way to read these tapes.
The best solution
would be an off-the-shelf SCSI - Pertec converter, which were made some
years ago,
but will be hard to find on eBay or such. Another way is to find the
SCSI interface
board for the 92185, but I've never found one to buy. Another way is to
get my
Vaxstation running again, the hard drive blew, so it would take some
effort to get
that back up. I have a Dilog DQ15 controller for it, and if that won't
work, I probably
have another tape controller, too. Another problem with the VAX is I'd
have pull
all the data off the tape over a serial interface, it was last running
VMS 4.7 without
TCP networking.
Anybody got any goodies in the basement, any good ideas of how to
interface it,
etc.?
One other choice is to build my own FPGA Pertec interface. The
formatted Pertec
interface is about as simple as you could imagine, but I'd need to add
an SRAM
buffer to the FPGA to handle up to 64K byte blocks.

RA drives, except the RA7x ones, are probably way too expensive to ship
longer distance.

Hum. Correct me if I'm wrong, but isn't the SA72 the box that holds up
to 4 RA7x drives? Same physical size as one RA90?
If so, then no, it don't hold 4 RA9x drives. Also, the RA70 works just
fine in it, as do all RA7x drives. RA70 is somewhat unique, though, in
that it was designed to also be usable without any front panel at all.
So there are dip switches on it that can be used to set the unit number.

I'm trying to identify a battery clip that seems to actually be a lug of
some kind. Would someone please take a look at
http://661.org/tmp/kk2048.jpg and tell me what it might be?
