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?
English is my second language, though I've been using it as my primary
language since I was 6. Because I learned it as my second language, I've
developed into one who's somewhat stilted in his usage of the language, and
also one who's very much aware of the application of grammar, syntax, and
orthography. I am, therefore, thoroughly convinced that American English,
if it follows the current trend, will degenerate into a sequence of
monosyllabic grunts and whines by the time another couple or three
generations have passed. Just look at the more recent additions to the
Webster International Lexicon of the English language: words like "duuhh"

I received this piece of fan mail from someone who had
visited my Ancient Alphabetic Art page at
It sounds like he's making an interesting video.
I'm sure he'd appreciate any insights from list members.
I haven't checked my archives to see if I have this
American Gothic image. If I don't, I might beg someone
to help him recover the files from his tape...

"In the case of the 1771 and 179x series it's possible to build a really neat
circuit I've seen but never tried to match, which uses the /TEST pin on the
FDC to cause the device to put out its pulses much faster, allowing them to
be accumulated externally in a counter, which, drives a DAC which drives a
VCO, which drives the counter as it downcounts the number of steps, thereby
slewing the head assembly. This could lead to an interesting but lengthy

I've just obtained an RML 480Z. This machine was commonly in use in
schools in the UK during the 80s, as an alternative to BBCs or Spectrums
under a government initiative to keep our computer industry alive.
Unfortunately, there are no cables or documentation with it. It has a
large array of DIN sockets at the back for cassette, two monitor
connections, and two serial ports. Does anyone have the pinouts for
I'll email Research Machines as well to see if I can obtain any
documentation, but the only reference to 480Z on their web site is on
the Y2K page, where it says that they don't have a real-time clock.
