Re: FTGH Large amount of DEC/Misc Classic computer hardware

[Guy Sotomayor Jr via cctalk]

I stopped by and picked up some stuff from Peter today.  There’s a lot of stuff
but I was only prepared to take a few items (I ended up taking a couple of tek
‘scopes too).

I didn’t have time to sort through everything that was available but there’s a 
lot!

He did mention that he has to be out of his space by May 31st and anything that 
isn’t
picked up will be scrapped.  I did take some pictures that I’ll put up sometime
tomorrow but what Pete has on his list below seems pretty accurate.

Pete is located in Richmond CA.  I can forward his contact information to anyone
that is interested in acquiring some/all of the remaining stuff.

That’s certainly the way I read it.

The SAVE command most probably is a locally written command or DCL procedure 
invoked by a symbol that does the magic of copying the files to the floppy.

The OpenVMS EXCHANGE command is the most likely tool used to transfer the data. 
As it’s name implies, it is designed to move data to and from foreign systems 
(where foreign in this context is most often a PDP-11 :-))

I stand corrected.  It appears that the handwritten label has a ODS1 style 
numerical UIC.

The printed directory may not actually be from the floppy media itself.  It is
hierarchical.   So perhaps it is from some ODS2 media that is holding the files 
that are being transferred to/from the Floppy.

 Lol, true. The disks will be given back on Monday.  It's no big deal.  The
 owners can decided what they want to do.  Even if I can't read it the
 disks, however, pondering just what the format might be is fun. I'm
 certainly learning something. Feel free to keep speculating if you are so
 inclined.

 Here it is:

 Some more info.  Anadisk tells me the disks are Single Sided, Single
 Density.  It can see ID marks as it tracks a disk but that is all.  It
 can't see any data.  Could be an RX02 disk as people say...

Philips Training Manual Introduction to Magnetic Disk Drives

[Fred Jan Kraan via cctalk]

Hi All,

For all who missed the 1980's technical details of diskdrives or lost 
the details in the mean time, I just put the "Training Manual 
Introduction to Magnetic Disk Drives" online which Philips provided in 
1987 as part of a Field Training. The rest of the documentation are 
technical manuals of disk drives like the Shugart SA455/456, SA400L, 
SA800/801 and CDC 9406. Assuming those are available, so I won't scan them


This manual covers floppy drives and hard disks, the latter with ST506 
and SMD interfaces.
