THE FLOPPY ROM: Software Distributed on Records (Oct, 1977)
Back in my Apple II days, I would occasionally get a magazine that came with a 5-1/4″ floppy inside. Later, of course, CD inserts became commonplace. But around the time I was learning to walk, Interface Age was shipping software by Flexi Disc. Little plastic records. First at 300, then 1200bps. It looked like it was insanely hard to get working but I find the idea that people went to this much trouble pretty inspiring.
I’ve attached some photos from my trusty BioniCam where you can see the binary nature of the disc, though I borked the focus ring so the 400x ones are a bit blurry.
Also, I wasn’t sloppy with the scanning. All that white crap in the record images is actually on the underside of the scanner glass. I guess I’m going to have to tear the thing apart and clean the inside too.

(Happy Computing with a General Ledger Account Program)
By popular request this month’s Floppy ROM™ is a business program rather than a software development program. The reception to Bud Shamburger’s General Payroll Package in the June issue was overwhelming with many additional requests for his General Ledger Package to be featured on a Floppy ROM™.

Dense disc (Jun, 1979)
“Unconventional” recording formats make recovering data from old disks a bit tricky. A problem the Archive Team has been dealing with as they endeavor to preserve roughly everything that has ever been stored. Ever.
The MD-4 computer mini-disc unit from IMSAI (14860 Wicks Blvd., San Leandro, Calif. 94577) uses conventional Micropolis drives, but unconventional 1024-byte-per-sector recording format. Result: an 18-percent—780K bytes-increase in storage capability. It’s $1995 with MDOS and controller.
Photographic Data Storage For Computers (Jan, 1948)
This is a pretty crazy way to store data.
Camera Snaps Answers
To speed recording answers in computing machines, Kodak has made a new camera that snaps 1,000 12-digit numbers a second. The numbers are photographed from a cathode-ray tube as spots; retranslated into electrical impulses by photoelectric tubes as desired for feeding back into the computer. Mosaic above is film section enlarged 25 times. A 100-foot strip holds 3,000,000 digits.
