Vintage Computer Magazines
Byte December 1977 Front Cover - Space Gamma 6 Holographic Museum
of Ancient Technology
Computer magazines and brochures provide historical perspective and breathe life into classic computers now obsolete, dormant and sitting silent on museum shelves. Before easy access to bulletin boards and the World Wide Web, magazines were one of the best ways like-minded computer enthusiasts communicated with each other. These classic issues are packed with how-to columns illustrating hardware repair, answers common questions, code snippets, schematics, and user reports. Most magazines included fun programming projects, experiments, and games that could be typed in by hand. Photographs fill the pages showing the computers in action, attached to suggested peripherals and displaying software in use. Trade show reports describe the current computers in production and hint at upcoming products.
I have selected an assortment of articles, ads, and brochures. Look beyond the main idea of the articles for references to competing products, embedded ads, predictions of the future, editorials, extinct companies, and advertising styles. Not everyone has a room full of classic computers at their disposal, and for those who don't, classic computer magazines are the next best thing! I hope that this assortment will be as inspirational to the reader today as they were then. Hopefully you'll see something new too.

Byte June 1976 Front Cover - The Game of Life Played in Color The computer program "Life" was originally written for the early DEC PDP minicomputers of the early 60's. It was quite a thrill for early microcomputer users to port this program to their Altair computers. If you'd like to learn the history of the program LIFE and how to write your own LIFE program, read the articles below:

Back cover of the June 1976 Byte. This image first appeared on the cover
of the premier issue of SCCS Interface, December 1975. Probably the most
beautiful computer ad ever.
The MOS KIM appears, plus the article "A Super Simple Cassette Interface" compares cassette storage mechanics with ASR 33 teletype papertape storage.
This is the August 1976 Microtek magazine back cover ad. PC 76 was one of the first East Coast USA computer shows. This was one of the first shows the likes of Apple, Processor Tech, Cromemco, etc. attended.

Vintage Computer Festival East 5On Saturday, Sept. 13th and Sunday, Sept. 14th another fun-filled festival of the forgotten. As with the past two events this years convention was held in the InfoAge Science Center at Wall Township, New Jersey. Sponsored by MARCH and VintageTech.
Here is my exhibit. Included was a Commodore SuperPET, Apple ///, Apple ][, and a Sage II computer. The focus of the exhibit was programming. I wrote a Waterloo Pascal trivia quiz program for the SuperPet, and a biorhythm program in Applesoft Basic for the Apple ][. Click image for larger version

Time to replace motherboard batteries
click image for larger version
Post from vintage-computer.com/ "...Anyone have experience cleaning up battery leakage, or should I just trash any system with battery problems? I dread the task of opening everything up that *could* have leaked, but I guess I have to do this asap. I have put aside a lot of 85-95 computers when I get them, they're not really in my area of interest, but at the same time I want to preserve them. I have 15 or so 386-486 systems, probably have 20+ bare motherboards from the e386-486 era, Amiga stuff, etc. All of this I have more or less ignored as "not vintage" - Maybe this is a mistake - whatever you call computers built before the ... read more

Archiving Apple II disksTest subject: Apple II GS with 3.5 and 5 1/4" drives, ADT 1.21 and a bunch of diskettes.
Apple II GS Computer running ADT 1.21
I decided it was time to learn how to archive Apple II disks by copying them (somehow) to a modern computer. I chose an Apple II GS as the bridge system because it has a 3.5 and 5 1/4" disk drive, and it can read old Apple II diskettes. The question is how to take make disk images and save them to 3.5 disk, and then find a modern system to read the 3.5 disks. Finally I will need to be able to both run the disk images in an Apple II emulator, and also move disk images from other sources to the Apple II GS for e... read more

AT&T UNIX PC 3B1 vs. 7300I received some AT&T UNIX PC parts this week from Mike Lee ( http://www.geekmuseum.org ) Specifically he sent me most of a UNIX PC "7300" model. I own a dead "3B1" model, which can be differentiated from the 7300 by it's raised monitor. I could not find any 3B1 images on the web, below is a link to my system's pics. There are plenty of the 7300's on the web. Anyway, I started into diagnosing what was wrong with my system, and his too. I was hoping to be able to merge my dead system with the parts from Mike's and create a working system. Almost... It turns out that the later model of the UNIX PC, the 3B1, has a different power supply than the older 7300 variants. Mike sent me a "middle version" 7300 with 1 MB onboard RAM. He sent me two good power supplies. Unfortunately... read more

Apple Lisa 210 A6S0200In preparation for class demonstration of the Apple Lisa 2/10 I took some new photographs. Minor repairs were needed.

Note the new pictures have the original mouse.... read more

TRS 80 Model II - restoration projectI had not used my model II for three years, and with this thread in mind I set up the old beast for a routine test. I try not to let any working system go too long before I re-run for a few hours to refresh the electronics. Anyway...I must have waited too long, she does not boot any more. The system powers up,but will not attempt to read the disk drive and there's nothing sent to the CRT. So far I have done little other than open the system and quickly inspect it. The CRT tube fires up (strong glow), so I assume that the issue lies with one of the four system cards (there is no motherboard). I have not done any further testing. If I have an update I'll post it.... read more

Raytheon VT302 ComputerLittle is known about the Raytheon VT302 office computer. I was able to boot the communications disk that came with it. I also took it apart and took pictures. I was surprised to find that this is an 8085 CPU computer. Very rare. I have the manual to the earlier version of this system, with cassette storage. Note the interesting controls on the Raytheon display. What's next? I would like to image the one working diskette, and possibly recover what appears to be the system disk.

Lear Siegler ADM 3ARestoration project notes for Lear Siegler ADM 3A terminal S/N 21818 from late 1977.

I cannot get the computer to respond locally either. I tried to jumper pins 2 and 3 (I believe those are the ones). Missing the dip switch cover. Updates to come. Pictures ADM3A... read more

Commodore BX-256-80 - 8088 Co-processorThe other day I saw some rare Commodore CBM 256-80 computers for sale and despite the lack of keyboards I bought them. Turned out to be a great deal!
CBM 256-80 with 8088 co-processor Upon inspection of the insides, I was surprised to find that both were actually the BX models. This is truly a rare find, indeed. The 256-80 BX is also known as the CBMX256-80 and the BX256-80. In the US the CBM 256 "BX" model with the 8088 co-processor was not officially sold by Commodore. The few 8088 cards that were produced in test/prototype batches were given to the Chicago B Series User Group for free. I have a copy of the release letter to prove it.
