Internal Hard Disk

Content to come. In the meantime, Wikipedia says “The product was unusual because the Macintosh did not have any internal interface for hard disks. It was attached directly to the CPU, and ran about seven times faster than Apple’s “Hard Disk 20″, an external hard disk that attached to the floppy disk port.”

Koala MacVision was a $400 combination hardware/software interface to digitize still frames from a video camera or VCR. The MacVision box plugged into either the Printer or Modem port. Data streamed in somewhat slowly: small frames took about six seconds to appear, whereas a full-screen image took 22 seconds. Obviously, one needed either a still subject or a device with good freeze-frame capabilities, such as a VideoDisc player.

Software authored by Bill Atkinson, and probably contained an early implementation of the “Atkinson Dithering” which would reappear in the software for Thunderscan. Curiously, the About Box for early versions credited Apple Computer — it’s possible that some of Atkinson’s work on dithering algorithms was done while he was still full-time at Apple:

Initially the software shipped as a Desk Accessory, so that it was available from other programs. Version 2.0 and above were standalone applications.
