  • Compute! (Fall 1979)

    The Fall 1979 issue of Compute! was the very first issue. I descended from The PET Gazette which exclusively covered the Commodore PET. With the transition to Compute!, it added coverage of other 6502 based computers. You may not think many people had computers in 1979 but the Apple II and Atari 400/800 were already mainstream choices based on the 6502 CPU. This issue of Gazette includes:

    • Selecting and Developing Small Business Systems – A guide to selecting the appropriate hardware and software for a small business.
    • Sorting Sorts: A Programming Notebook – Evaluating different sorting routines including selection sort, bubble sort, and shell sort with BASIC examples.
    • Len Lindsay Reviews Three Word Processors – A look at three word processors for the Commodore PET including Commodore Word Pro II, Programma, and Connecticut Microcomputer WPP.
    • Microcomputers for Nuclear Instrumentation – An excerpt from a paper about using Commodore PET computers to solve nuclear instrumentation problems at the Savannah River Laboratory.
    • Tokens Aren’t Just For Subways – An article explaining tokens and a method to list them in BASIC.
    • Universal 6502 Memory Test – A memory test program that works with various 6502 based computers.
    • Microcomputers in Educations – Excerpts from The Microcomputer and the School Library Media Specialist.
    • Flying With PET Pilot – A look at the usage of computers at Peninsula School in the San Francisco Bay area and the software used.
    • Teachers, Computers and The Classroom – A look at the future of computers in the classroom.
    • Atari Computers: The Ultimate Teaching Machines? – Comparing the Atari 400/800 to other similar computers for the purposes of classroom use. Ultimately, Atari never did very well in the classroom as far as I know. Commodore had some success but it was Apple with the Apple II that dominated throughout most of the 1980s. This was more of a marketing and sales success than necessarily being better for the purpose.
    • The Evolution Of A Magazine – A look at how Compute! evolved from The Pet Gazette.
    • A Commodore Perspective – A history of the Commodore PET.
    • Retrofitting ROMs – A guide to upgrading the ROMs in your Commodore PET.
    • PET Screen Print Routine – A type-in program for printing the contents of the screen to a printer.
    • TRACE For The Pet – A type-in program that will display each line of a BASIC program as it is executing.
    • 32K Programs Arrive – A look at Temple of Apshai for the Commodore PET.
    • Using Direct Access Files With The Commodore 2040 Dual Disk Drive – Apparently these drives only supported sequential access via the built-in DOs. However, utilities were provided that allowed pseudo-random access by indexing via a separate sequential file.
    • Mastering The Ohio Scientific Challenger 1P – Some examples of using and programming this single board computer.

    Reviews

    • D.C. Hayes Micro Modem – A 300bps modem for the Apple II for $395.
    • PET SET 1a – This equipment allows you to collect analog data from several instruments directly with your PET.
    • Petunia & Petunia Player – A system for creating and playing music with the PET.
    • Corvus 11A Disk Drive – This 9.6 Megabyte hard drive for the Apple II would have set you back $5300 in 1979. That may sound like a lot but it’s even more when you factor in inflation. Adjusted for inflation, that was equivalent to about $23,040 today.
    • Macro Assembler And Text Editor: Sym Version – A look at the SYM version of a 6502 Macro Assembler and Text Editor. Versions are also available for the PET, Apple II, and other 6502 machines.
    • Challenger 1P – A review of this relatively inexpensive single board computer designed with BASIC programming in mind.
    • Aim 65 – This single board computer from Rockwell International includes a full size keyboard and built-in printer.

  • Byte (November 1988)

    Byte was one of the first computer magazines published in the U.S. It covered a wide variety of ‘small systems’ including both home computers and machines made for businesses. However, it seemed the popularity of Byte faded the more the popularity of the PC grew. Nevertheless, for much of its life it was extremely popular and issues were huge including this one from November 1988. Contents includes:

    Products In Perspective

    • Short Takes – Brief looks at the NEC Ultralite (NEC V-30 CPU, 640K RAM, 1 or 2 megabyte “silicon drive” (NVRAM), DOS 3.3), NEC ProSpeed 386 (portable computer with 16-MHz 80386 CPU, 2 megabytes RAM, 1.44MB disk drive, and 40 MB hard drive for $7699), Compaq Deskpro 386/20E (Compaq’s latest slimmer desktop featuring a 20-MHz 386SX CPU, 1.2MB floppy drive, 1MB RAM for $5199), and more.

    First Impressions

    • The NeXT Computer – NeXT was never much more than a niche product but with it, Steve Jobs laid the groundwork for what would become Apple’s future. The original NeXT cube featured a 68030 CPU, 8 MB of RAM, a Unix based OS, a DSP, and the first production erasable optical drive. It wasn’t cheap though at $8500.

  • Digital Archaeology: Floppy Disk #14 – SEP84.DOC

    A summary for those that haven’t been keeping up with this series:

    I found a number of 5.25″ disks at a thrift store a number of years ago (sometime in the late 1990s to the best of my recollection). I finally got around to acquiring a 5.25″ disk drive and extracting the contents a several years back. Since then, I have been occasionally posting the content here.

    Based on the contents, most or all of these disks were apparently once owned by someone named Connie who used to run the “Close Encounters” Special Interest Group (SIG) on Delphi in the mid 1980s.

    The following description of this SIG was found in a document on one of the disks: “This SIG, known as ‘Close Encounters’, is a forum for the discussion of relationships that develop via computer services like the Source, CompuServe, and Delphi. Our primary emphasis is on the sexual aspects of those relationships.”

    This service was text based and was accessed via a modem and whatever terminal program you had available for your computer to dial in with. Many of these disks have forum messages, e-mails and chat session logs. All of this is pre-internet stuff and I am not aware of any archives in existence today that contain what was on Delphi in the 1980s.

    This post includes the contents of SEP84.DOC. This appears to be a report that gives details on the usage of the SIG (how many hours each user spent in the SIG, etc.). This is in the from of an e-mail from someone named KELLY who was presumably an employee of Delphi. The e-mail is dated October 4th, 1984.

    There are two SIGs (Special Interest Groups) that have been mentioned repeatedly in these files. One is the “Close Encounters” SIG and the other is the “Friendship Circle” SIG though I’m not entirely sure they were different. “Close Encounters” may have evolved from “Friendship Circle”. In any case “Closed Circle” is mentioned in this report but maybe this is an alias or the name changed again at some point. This report has a much larger number of users than the previous one from August.

    One thing to note is how it lists “PRIME” minutes separately from “OFFPRIME” minutes. Off prime minutes would have cheaper than prime minutes or even free (outside of the monthly Delphi subscription fee anyway). These would typically be from some time later in the evening until some time in the morning. Prime minutes would be the busiest time or at least the time when business customers were online. If you were online during prime minutes than you were paying a per minute access fee in addition to your subscription. This is kind of how things worked in the early days of cell phones too.

    This file is dated September 2nd, 1985 and was in a subdirectory titled “SIGUSAGE”.
