I'm still digging. I found more 550 stuff. I think this is everything
that came with the 550. Here's a chance for you 550 owner's to get the
whole set at one shot!
Original DS-DOS box and invoice.
Original Sanyo Easywriter ver 1.3 disk
Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two
original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4
are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1
Original Sanyo disk box with all three original disk of set A, WordStar
and CalcStar and a backup copy of DS-DOS.
Two card board dummy disks used to protect the floppy drives duing shipment.
>A few weeks ago we were talking about the Sanyo 550 series and someone
mentioned one of the alternates operating systems that supported 80 track
drives in the 550. I said that was DS-DOS by Michtron.
> Today I found an old Sanyo disk package with four disks for the 550. One
of them is DS DOS 2.11, one is InfoStar, one is MailMerge/SpellStar and the
other is a disk of misc utilities. The first three are original disks. In
additon, the InfoStar, MailMerge/SpellStar are Sanyo labeled disks that
came with the 550. If anyone wants them, trade me something I can use and
they're all your's.
I recently filled the car with these:
Apollo DOMAIN Series 3500
Domain series 3000 model 3010
HP/Apollo series 400
(2) Sun 3/60 + tape drive and tapes
Apple lisa 2
(2) apple II Ci
Mac SE/30 with radius monitor
Mac color classic
power mac 7200/90
Also available was a volker Craig terminal, and a copy
I also have "quite a pile of HP 712/715/725s in various
condition" for me to pick up when I get some space cleared.
IKEA has said that the missing piece to complete the
shelving will be delayed another 3 weeks, and my wife says
no more machines until the shelves are up!
hey do you have any ideas about using relays or some thing connected to a parallel or aerial port to control the power to an outlet, you know like a dimmer switch controlling motors ETC
if you have any thought or ideas I'd be glad to hear them.
I am getting my PDP-11/34 and my RK05 disk drives and packs tommorrow, and I have a few questions.They have have been in storage for years, and, although they have been kept dry, they are probably dusty. Can anyone tell me how to clean the drives and the disk packs before I use them?

It's fallen a bit out of fashion in the past few years, but 10Base2
(50-ohm RG58 Coax) is particularly useful for the "home runs" between
twisted-pair hubs. Many twisted-pair hubs come with Coax connectors for
just this purpose.

There is an IBM 9370 Mainframe coming available in my area, and I'm
considering acquiring it (never had my own mainframe to play with).
I haven't been able to find much on the Web about this family of systems.
Can anyone point me to some info or confirm/deny the following facts:
System produced: circa 1986 - 1988
Intended market: "departmental mainframe", 20-100 users
Operating system: VM/SE
Weight: 300 lb racks; 200-300 lb processor assembly; drives ???
Typical peripherals: DASD drives, high-volume, heavy printers (500 lbs +),
tape drives, PS/2 consoles
Networking: ASCII subsystem for terminals, Ethernet?
Power and Cooling requirements: 3 phase power (240 V)??
I suspect that this system will be too large for my available space; is
anyone else in or near Western Canada interested in the system in whole or
in part? Thanks for any help.
Thank you for being so helpful. I will run the tapes and see what happens. I
trust the SA is usually 200 (except for Tic Tac Toe which I know is 400).
BTW: Does DECUS still sell this stuff?
