To tell the truth, I can't think of ANY IBM that had a factory reset switch.
My L40sx laptop has a place on the mother board for one, but no actual
external switch.

I have a couple of Mizar VMEbus Video boards, model 7710. Has anybody an
operator's/technical manual? Either an original or decent xerographic copy
will do. Has anybody written an OS-9/68K ver. 2.3 or 2.4 driver for this
thing? These are 1989 vintage.
I'm also looking for the following Motorola VMEbus Module manuals:
** MVME 236-1,2,3 (Publication number MVME 236-1 Dx ), DRAM memory module
(x = version or edition number. I'll take any version.)
** MVME 133-1 ( " " MVME 133-1 Dx ),
Processor module
** Support Docs manual for this processor: SIMVME133-1
** MVME134bug ( " " MVME134bug Dx ), debugger
manual for '134 processor module
** and finally the Support Documentation (schematics, etc.) for an
MVME147S which is publication number SIMVME147S. Already have the manual.
** I'm also looking for Xycom catalogs and any tech documentation from
back in the mid-80's.
Thanks for your help!
Regards, Chris
PS: Are there any of you out there who have VMEbus gear in your collection?

G'day,
The thing consists of tape feeder (model 1227-2001) and punch itself (model
1215-1001). It was manufactured by VEB Rechenelektronik
Meiningen/Zella-Mehlis, GDR.

What do you think a Corvus Concept would bring to Blockout? I don't know,
and it's been years since I played Tetris.
Yep, I've got one, the fancy landscape/portrait display boils down to
a VERT/HORIZ switch on the back of the CPU that the software reads to
figure out how to draw the display. (It's up to the user to make sure
the switch and the monitor are set the same way, and the switch doesn't
change anything about the beam deflection.)

Our Spectrum Management Agency (or whatever it's called this week) has a
less enduser friendly attitude towards dipsticks in fringe areas that think
they should be able to watch marginal signals on "rabbit ears" inside a
substantial building.
It amounts to "Get an outdoor antenna." No outdoor antenna, no valid
grounds for complaint. There are no specific regs regarding emf emission
>from computers, they have put the onus on the RECEIVER manufacturer to
ensure adequate filtering & shielding from unwanted signals. The CB fad of
the 70's was a direct cause of this, after it was discovered that perfectly
functional CB's would drive certain televisions berserk because of stupid
choices of IF frequencies (Amongst other "They did WHAT!" type design, um,
features.)
If you have a properly installed external antenna (Yagi of some kind - cut
for the channels you are trying to receive) and proper coax feed into the
set, and you are STILL getting interference, only then will they look into
it.
This attitude has cured enormous numbers of problems.

If you wanted access to the RT-11 files on the RL02, you'd use FLX. Type
HELP FLX at the MCR prompt.
I suspect that you want to access the "raw" image, though. If you were
using 11M+, you'd do a MOU /FOR, then you'd be able to block-address
the drive as the file "DL0:", etc. Under 11M you don't even have to do
the /FOR (though you may have to do an ALLocate.)

Depending on the version and the tape interface and what software you have,
yes it can be accessed over the network. The best way to do this is to
have the machine with the drive do TMSCP serving to the rest of the cluster,
though there do exist DECUS freeware tools for non-cluster serving across
DECNET.

FAL on RSX won't let you do so. But you could upgrade to 11M+ 4.5, and
use VCP to make a tape image. But even this isn't very smooth.
My favorite solution would be sneakernet - pull the drive and controller
and move it !

They aren't all that obscure, but they're all three available at my local
thrift store (sans power cables). If anyone would like me to pick them up,
shoot me an email. I'm not a particular fan of any of these machines, but I
figured someone on the list might be interested.

hazeltine was a popular terminal, like the AMD Dumb terminal. The 1500
series were in use about 1977. They made US and Europe powered models. Sold
by Computerland etc.
It looks like the last version of SunOS that I can run on a Sun 1/100U
is version 4.0.3, however i'm not sure if I have enough ram to use that
version. It looks like I can only add 2 ram boards, and all I have
are 1Meg ram boards...
Does anyone have 4.0.3 that they could supply to me in some form? Or is
there a better alternative for sun 2's with low ram (sun 1/100U is
apparently very hardware equivalent to the earliest sun 2's, at least
>from a software perspective). Perhaps there is a X11 version that might
run acceptably from a sun with 2Meg of ram.
The Sun 1/100U does not have any way to connect peripherals such as
hard drives, so the unit will have to be booted from the network.
I guess its almost time for me to brush up on tftp protocol, assuming
I can find some OS to run on this computer.
I dont suppose anyone has a sun multibus 4Meg memory board they would
be willing to trade?
