- While going through a box of books from my father's college
- days, I came across the August 1960 issue (vol. 33, no. 8) of a
- journal called "Instruments and Control Systems". This is chock-full
- of interesting advertizements for (now) obsolete instrumentation,
- test equipment, and computer hardware, including the following (p. 1312):

- The Bernoulli Magnetic Disk Memory,
- a proprietary development of The LFE SPECIFICATIONS BD-100 SERIES
- Applied Research Laboratory, is now Storage Capacity (Max) Bits 100,000
- available in prototype or production Bits Per Track (Max) 3,000
- quantities. Bit Rate -- kc 90-400
- Track Layout as Required (Typical)
- The first models, designated as the Total Tracks 40
- BD-100 Series, are ideally applicable Data Storage Tracks 32
- for use in general purpose EDP Systems. Spare Tracks 3
- In addition, because of each unit's Clock and Timing Tracks 3
- small size and weight, and ability to Register Tracks 2
- withstand sever environmental condi- Number of Registers 4
- tions, the BD-100 series is also appli- Register Length -- Bits 32

- and mobile digital computers. For a Disk Speed -- RPM 1,800-8,000

- So is this the original "Bernoulli box"? :) The picture
- of the unit is a cutaway drawing showing the disk platter, R/W
- heads, and spindle motor. The housing with electronics appears
- to be at least a 1-foot cube. No price is given :)
-
- Many of the other ads in this journal are (to me, at any
- rate) surprisingly sexist. One from Eldorado Electronics says
- "How Do You Measure and Sort? This way --> [woman sitting in
- front of giant 'scope] or this way --> [tiny box; line drawings
- of woman and 'scope with Xs drawn through them]" (p. 1410). Another
- shows a Bob Dobbs type lounging against a Benson-Lehner computer,
- leering at a pretty keypunch operator; a comic-strip word balloon
- from the man has punchtape and punchcard holes, while the woman
- says "I was beginning to think you'd never ask!" (p. 1264).
