Re: IBM 3330 Drive

[AJ Palmgren via cctalk]

For reference, here is a picture of the disk pack that I am wanting to
read.

http://bit.ly/2etUg30

I know, I got a bit nervous too when I saw the guy just holding it out
exposed like that.  Let's hope he put it back in the canister very
carefully and quickly.

Can anybody guess the correct model of disk pack from this single picture
and angle?  (Sorry, it's all I have to go on right now).

Thanks!

RE: IBM 3330 Drive

[Paul Birkel via cctalk]

I'm afraid that I can't help.  But I notice that in the upper-band of the glare 
there appears to be a lot of speckling of the oxide surface.  Is this to be 
expected in a heavily-used disc-pack, or does it indicate surface damage -- and 
if so then what are the likely causes?

Also, was it usual to place markings/labels on the lower-ring like this -- both 
what appears to be one that is painted-on "NEWUC:2005.47" as well as the 
(plastic covered?) insert "SHARE1"?

Re: IBM 3330 Drive

[Jay Jaeger via cctalk]

The SHARE1 is on the plastic insert label designed for the purpose.  Usually it 
would be the IBM OS Volume Serial number.  The pack in the photo may have 
contained stuff that originated with the IBM SHARE user group, or perhaps the 
pack was used on a drive shared between two systems.  The painted on number is 
unusual, and may be a Julian date, from 2005, perhaps from a repair, though 
that would be pretty late for this kind of removable disk pack.

Packs like this were exposed every time the pack was mounted or dismounted from 
the drive, when the cover was pulled off with the drive door yet to be closed.  
Many such drives ran a set of brushes  over the pack surface as the drive spun 
up, before loading the heads.

Perhaps because some of those blacklists at times block things for political 
reasons?  I remember when one of them decided to block every comcast address, 
because of some braindead notion I could never quite understand.

Viva Amiga documentary on Hulu

[Sam O'nella via cctalk]

I haven't watched the entire thing yet but Hulu correctly identified it as
an item of interest for myself.  http://amigafilm.com/  It may be available
other platforms (I did notice some copies seem to be on youtube although
not sure if that's legitimate).

Either way seems like a fun watch if you're an Amiga/Commodore fan.
Definitely won't be an unbiased production ;-) but saw some local mailing

RX02 Emulator

[Douglas Taylor via cctalk]

In my other post I asked about DEC 11/2 and 11/03 cpus and 18/22 bit 
backplanes.  I am still interested in this but I am considering what 
type of disk to run from.


I ran into a rx02_emulator on github and looks quite interesting, since 
it uses an actual DEC RXV21 interface it would be compatible with the 18 
bit addressing.


Does anyone have experience with this emulator?

Where can you get the circuit board that is part of this project?

I have no idea of what's going on--best to whitelist me if you want to
see my posts--OTOH, maybe not. :)

I've noticed that some of the mail spam classifying services (DNSBL for
example) automatically dun a whole domain.  Since I relay my mail
through secureserver.net, that means that the thousands of people who
use the secureserver domain get slammed as spam.  It's a very common
complaint over at godaddy.com's hosting forums.

Spam, unfortunately, like junk calls and telemarketers is getting
smarter.The folks at paypal.com report that over 95% of all email is
spam.

The price of progress?

RE: IBM 3330 Drive

[Tom Gardner via cctalk]

In the absence of a marking I would expect this to be a -1.  See if u can find 
a 3336 model number.  If there is no dash, then it likely predates the -11

Take a look at the other side of the pack.  As I recall to prevent mis-mounts, 
there was a pin and socket arrangement in the -11 pack; a -1 top of spindle was 
small cylinder with a flat top, but the -11 top had a contour (raised socket?) 
that matched an inverse contour (pin) in the bottom of the pack (or maybe the 
other way around) so that it was impossible for -11 packs to be mounted on -1 
drives and vice versa.

I agree the label "Share1" means it is likely the CKD format.

I suspect the speckling in the light band is just surface variations and has 
nothing to do with wear.  Oxide disks were not very smooth when compared to 
today's metal film disks.

origin of 3D-printing?

[Stan Sieler via cctalk]

Hi,

Perhaps not quite on topic, but it's antique ... and computer-tech related
...

I just found what might be the first ever reference to the concept of
3D-printing.

In the Decmber 1951 issue of Galaxy Science Fiction magazine is a story
"With These Hands" by
Cyril M. Kornbluth.  In it we see, on page 74:

   "You just pour in your cold-set plastic, the
   nozzles ooze out a core and start crawling over
   to scan — a drop here, a worm there, and it begins
   to take shape."

The text is discussing how a 3D statue is created from multiple photos of a
person.

https://archive.org/details/galaxymagazine-1951-12
(magazine page 74, PDF page 76)

I was wondering if any earlier references to the idea existed.

thanks,

Stan Sieler

Re: Viva Amiga documentary on Hulu

[Ed Thierbach via cctalk]

Thanks for passing this along ... I just watched it, and enjoyed it quite a
bit.  Being an early Amiga fan, it was fun to relive some of the excitement
of the early days.

Yet Still More for VCFMW

[Marvin Johnston via cctalk]

My last email about what to bring to VCFMW let me off the hook (so far) 
for a number of things. So time to try again :).


I've had some questions about what I want to unload. There is far too 
much stuff to even try to answer such a question. An easier way is to 
say what you are looking for, and I'll answer as best I can.


Examples of stuff off the top of my head that it would be fun to bring 
(but the volume is just too great.) All computers can be assumed to be 
untested although most did work when I first got them:


AT&T 3B2 w/original UNIX software/cables/two AT&T terminals
Commodore Pet, 2001-8, CBM, etc
HP 85B
HP 86B
HP150 (HP150-II???)
HP 82906A HPIB Printer
HP 82901M Dual 5.25" external floppy disk drive
Xerox 820-II w/docs, disks, dual external 8" drives
IBM PC w/16K-64K motherboard
IBM PC w/64K - 256K motherboard
IBM AT motherboard w/80287 math coprocessor
Macintosh SE w/original box, working
TRS-80 Model II working condition unknown
TRS-80 External 8" chassis, rough condition (especially the 8" drive)
Tektronix 1711 Two Axis Machine Control Unit w/docs, worked in the 70's
PDP 11/23 Chassis only (no cards) needs cleaning
SOROC IQ-??? not working (bad keytronic keyboard)
Vector Graphic Vector 3, not working, bad keyboard
Vector Graphic MZ
Heathkit H-89
Printer for IBM 5100 computer
Philips microcomputers
Wang microcomputers
A LOT of IBM manuals (maybe 500 or so) circa 360 era (Al has scanned a 
lot/most of them.)
A LOT of Burroughs manuals, maybe 500 or so (again Al has scanned a lot 
of them.)

Original Zenith 100 manuals/software (maybe 10 or so)

The list above does not include all the Apple, TRS-80, Atari, Commodore, 
Compaq, IBM PC/XT/XT-286/XT/AT conmputer, S-100, etc. stuff I have. Not 
listed is also the small stuff that I'll be bringing to VCF anyway.


Prices are not included since I haven't researched most of them. So if 
interested, make a fair offer. I'm open to trades, especially 
Polymorphic stuff I don't already have, ditto for Lobo Drives, and a 
double sided scanner at least 600 dpi.


If you asked about something and I failed to respond, please ping me again.

Note: the TRS-80 model 6000 computer from the last listing is gone. And 
possibly/probably the PDP 11/05 (along with a couple of other things I 
had dups of, but still have one more of.)


Thanks!

Marvin, KE6HTS 

Re: origin of 3D-printing?

[drlegendre . via cctalk]

Not sure how relevant this is, but a friend of mine has been solely
developing the Sandwich Printer (tm), at least since his days at the Miles
Davis Anomalous Jazz Propulsion Laboratory ,in the late 1970s.

Jay & Paul,

Thank you both for your input here.  This is extremely educational and
valuable to me, and highly appreciated!
