This message is for Mike McFadden.
I came across your message while looking for a replacement for my informer 207.
What info are you needing. I think that I have a photocopy of the
manual around here and a few other pages of info.
Your message said you had 2 of these terminals.
Would you be interested in selling one? If so, at what price.
The one I have just died and I need a replacement. I use it as a
serial terminal on an old SCO Xenix computer, that has been running since 1984.

I have heard of something similar called "Mocha SMB" which at least would have been shareware, but have hitherto been unable to find it anywhere. This would perhaps be my best bet.

The data is still backed up somewhere else and the OS 8 drive was a fresh install so there's not much to worry about (and yes, I have installed and moved SCSI hard drives in several sorts of machines and enclosures...) but I don't yet understand why I would need a commercial product since OS 8 rather clearly states that it is able to use DOS formatted media - but doesn't go out of its way to point out how (the help "wizard" gets hung in a loop where it repeatedly asks me to select the volume I want to format although it already is).

Two nice ideas for which I might actually even have the hardware (dunno if an iMac is going to take OS X and my HP NetServer LH6000 would be a bitch to set up because it's so huuuge), but both depending on additional commercial software.

Linux, see above.

The OS 8 install includes Netscape 3.something which just might work as an FTP client, and WarFTP is free, so this is probably what I'm going to try next.

Totally new stuff to me, too much to learn.

I had already contemplated that but will only use it if all else fails.

This is what I was already trying with that hard disk, but couldn't find a format which both machines could use.
Resource Forks are of no concern since the stuff was all generated and used under Windows until now.

I was watching "How It's Made" on the Discovery Channel this morning,
and they were constructing speakers. As they went to magnetize the
ferrite ring, I noticed the operator working with an interesting
three-button control panel.
The button he pressed was a red "Fault" light/button. To their left
was a beautiful white "Ready" light/button, and one marked "Write
Protect". This strikes me as a very interesting magnetizing

my high school got one in 1971 and through the punch cards, you could get to binary &, |, and shift commands as well as program jumps. I have a complete one in a box with reader, manuals, unused punch cards, etc. It was an eBay nostalgia buy a few years ago. One of these days, I will be organized enough to have it on a table to play with it. It was always fun to see the flashing nixie tubes as it ran calculations.
As to the tech inside, I would expect that it was a multi-LSI "big" chip dedicated calculator design, so any memory was probably implemented as registers in the chips. JUst a gues anyway.

I pulled out NETBOT:: a 12mb uV2000 with a RD53 and booted it with the
case off to get the temp and the hotter of the two chips stabilized
at 58C +- a tiny bit while running VMS 5.4-3.
Like I said they do run hot.

My second question concerns data transfer between (Windoze) PCs and Macs. I got a Power Macintosh 7200 (with Mac OS 8.0) which I would like to move some data to (approx. 3 GB); filesharing over Ethernet doesn't work without additional software since the Mac doesn't understand SMB/CIFS and W98/2k (not Server)don't understand enough AFS. "Web Sharing" only supports the opposite direction (PC can read data from the Mac) unless I'm missing something.
So what I'm left with is pushing the stuff onto an idle 4GB SCSI disk that I can then hang off the Mac. Unfortunately I couldn't get an idea how to accomplish this: if I format the disk on the PC, the Mac will come up with "Uninitialized Volume". Initializing the volume as "DOS 4GB" doesn't work, the same dialog comes up again after I restart and going back to the PC I can even still read the contents! I tried one FAT32 partition (primary) as well as two FAT16 drives inside an extended partition.
Thanks in advance, yours sincerely

I've just acquired a VAXstation 2000 (thanks Mouse!) which exhibits what appears
to be an overheating issue.
Powered up ir runs for about 10 mins or so (just sitting at the console prompt
doing things like TEST 50 to display the configuration, pressing ENTER to get
another '>>>' etc.). After about 10 mins (give or take) it fails, sometimes
appears to reset, hangs etc.
Firt thing I noticed is that the two surface mount chips with the round heatsinks
affixed to them get *HOT* ... Hot enough that you wounldn't want to keep your finger
on either of them for very long.
I believe these are the CPU and FPU chip? - Is this normal for them to run this
hot? They don't heat up alarmingly quickly, but after a few minutes they are
hotter than I'd think normal.
Aside from the eventual failure, it seems to run correctly - the self tests
(including the FPU test) pass (except for those which don't have hardware installed,
loopback connectors etc.
When I got the system, it was jam packed with cards, including the main board,
color frame buffer, double-sided memory expansion and an ethernet interface.
During my testing, I've removed all of these except for the main board, and am
running the system as a MicroVAX. I do have the resistor/loading card installed
as is recommended when running the system lightly loaded.
Power rails all look good - There is a 9V supply which the technial manual
describes as "for loading" which has a separate supply and return. Relative
to ground I measure about +5.6v on the supply and about -3.3 on the return,
which I'm assuming is normal (?)
Anyone know where I can obtain anything resembling a schematic? Other technical
information (I have a PDF of the technical manual, however it's mostly "system
information" from an operational point of view). Any known issues etc.?

> Were all the early 80's IOmega's SCSI or did they use something before that?
The earliest devices were full height 10MB 8" SCSI drives that had optional slave
drives attached. Their main claim to fame was using floppy type media.
The first Syquests were MFM ST506, using removable plated media.
