Ohio Scientific Instruments OSI Challenger 6502 Vintage PC personal computer Byte Magazine advertisement scan - 1977Simple beginnings

This ancient personal computer ad comes to us from February 1977 in Byte Magazine — before the launch of the Apple II.

Like the Apple II, Ohio Scientific Industries’ Challenger PC used a MOS 6502 CPU.

I don’t know too much about OSI, since I have never owned a machine they made, but I know that they were very important in the early PC industry. I found a really neat website about OSI boards if you want to learn more. You can also learn more about their complete systems, including those with Apple II-like built-in keyboards at this website.

[ Retro Scan ] The Hayden Sargon Hamburger

Hayden Book Company Computer Program Tapes Software Sargon Game Playing with BASIC How to Build a Computer-Controlled Robot The First Book of KIM General Math Complex and Matrix Math Introductory Engineering Math advertisement scan - 1979Starving for Software? Eat a tapeburger

For some reason, I find few things less appetizing than a black and white hamburger. (Maybe one with a computer tape on top of it.)

But we’re not here to eat this advertisement for Hayden Book Company’s 1979 computer tape offerings. We’re here to look at it.

I know very little about Hayden itself other than that it originated as a New Jersey-based book publisher and later transitioned into selling software on disk and tape as well (as “Hayden Software”). That stands in contrast to what I think was the firm’s first approach to publishing software — in paper books full of source code.

It’s worth noting that this might be the first-ever advertisement for what was originally called “Sargon: A Computer Chess Program“, a pioneering chess game and engine for personal computers that debuted at the 1978 West Coast Computer Faire. I recall my brother playing Sargon II for the Atari 800 and Sargon III on the IBM PC, and I had a copy of Sargon II for the Apple II. It was a stalwart, well-respected chess series for many years.

Macintosh II 25th Anniversary at Macworld

25 years ago this March (1987), Apple released the Macintosh II, the first open architecture Macintosh. Naturally, I’ve written a short feature about this pioneering machine over at Macworld.

While speaking with Michael Dhuey, the Apple engineer that conceived the Mac II, I learned that Apple patterned the Mac II after the 1977 Apple II, which sported the same sort of flexibility and expandability as the Mac II. That self-referential influence amazed me — especially coming from a company that recently institutionalized the practice of ignoring its own history.

But only two years after Steve Jobs resigned from Apple, the company had no problem making the un-Jobs move of both looking backward and opening up the Macintosh. The result changed the course of Macintosh history.
