[TUHS] 1974 CACM Paper, was Re: history of sbin?

[Norman Wilson]

Herr Doctor Wkt:

  Does anybody have a PDF of the 1974 Unix CACM paper, I seem to have
  misplaced my copy.

=======

It appears to be generally available via the ACM Digital Library,
of all places.  (No, I'm not so smart: Google pointed me there.)

It appears to be the genuine 1974 version, though my paper copy
of that issue of CACM is buried behind too many boxes right now
for me to dig it out and check.  Disk storage for `The PDP-11/45
on which our UNIX installation is implemented' is as Warren
describes for the 6th Edition update: 1MB fixed-head disk,
four 2.5MB removable-cartridge drives, and a single 40MB
removable-pack drive.

And Dennis' paper on the Evolution of Unix says:

	During the last half of 1971, we supported three typists from
	the Patent department, who spent the day busily typing, editing,
	and formatting patent applications, and meanwhile tried to carry
	on our own work. Unix has a reputation for supplying interesting
	services on modest hardware, and this period may mark a high
	point in the benefit/equipment ratio; on a machine with no memory
	protection and a single .5 MB disk, every test of a new program
	required care and boldness, because it could easily crash the
	system, and every few hours’ work by the typists meant pushing
	out more information onto DECtape, because of the very small disk.

Any guesses as to the hardware?

0.5MB: RF11-A/RS11
1.0MB: RS04/EJS04
2.5MB: RK05/RK11-D
40MB:  RP03/RP11-C
200MB: My peripherals handbooks only go up to 1975.

Cheers,
	Warren

Does anybody have a PDF of the 1974 Unix CACM paper, I seem to have
misplaced my copy.

The 6th Edition update to the CACM paper says:

	Our PDP-11 has a 1M byte fixed-head disk, used for file system
	storage and swapping, four moving-head disk drives which each
	provide 2.5M bytes on removable disk cartridges, and a single
	moving-head disk drive which uses removable 40M byte disk packs.

The 7th Edition update says:

	Our own PDP-11 has two 200-Mb moving-head disks for file system
	storage and swapping.

Thanks,
	Warren
