The IMSAI 8080: The Altair 8800's Most Popular Clone
Вставка
- Опубліковано 19 сер 2024
- The IMSAI 8080 is an early microcomputer released in late 1975, developed, manufactured and sold by IMS Associates, Inc.. It is based on the Intel 8080 and later 8085 and S-100 bus and largely regarded as the first "clone" microcomputer as it is a clone of the earlier Altair 8800. The machine ran a highly modified version of the CP/M operating system called IMDOS. In total, between 17,000 and 20,000 units were produced from 1975 to 1978.

Awesome dude, thanks so much for sharing. I'd heard the stories of music played from early homebrew PCs thru radios but had never seen it done until now. Well done!
Thanks for the video. I was reading 'Once upon a time in Computerland' and was wondering was the heck this machine was (And yes I'm old, my first pc was an Apple II+ in 1982)
The IMSAI was already painfully obselete at the time WarGames was filmed. This was deliberate, to show how resourceful Matthew Brodrick's character was as a hacker even on a student budget with really old equipment.
Love the look of this machine, thanks for sharing
Hence why the FCC required RF Sheilds... To prevent RF spillage from the CPU Clocks onto the AM Band.
Thank you so much for sharing!
Hi there. Can you add a link or more info for the serial/terminal system system you have set up? Is it “cutter”? What hardware is that? ThNks!
The music program for the PDP-8/L in High School was much better. There was also a 4-part version.
Love the demo. Although I think you should have mentioned that CUTTER is actually from Processor Technology (SOL-20) and you do not have to type out DUMP you can simply type DU to Dump and EN to start Entering data and Ex to Execute. I have never performed this demo, I have always demoed the Kill the Bit program, so everyone can see the cool flashing light on the front panel.
Looking forward to experimenting and showcasing with that additional demo and information in the future!
@@intergalacticmuseumofcompu6880 I would really like to meet with you, and take the tour of all your great systems, and visa versa, if you have a chance to make it up here to Palm Coast, I would love to show you all of my systems as well. Novell2NT@gmail.com
@@intergalacticmuseumofcompu6880 I am still waiting to hear back from you.
It was great meeting you guys up here in Palm Coast. Just checking in, to see if there is anything new happening in regards to setting up your museum.
Great demo!
You can hear a remote control send data by holding it near an AM radio.
Maybe an RF one but not IR.
it had no programs or software! it was in binary and only used by TRUE GEEKS! the college had one for students to play with but the plastic buttons broke on it and could not be replaced.
How did what is essentially an unlicensed AM transmitter ever get FCC approval? :) That is some serious RFI from the computer.
Steve Dompier's May 1975 People's Computer Company newsletter article Music of a Sort (republished in Dr. Dobbs Feb 1976) describes how one would generate music with a MITS Altair by using the front panel to generate tones that could be received over an AM radio. The goal of this project is to experiment with ways to automate the use of this program by creating a "jukebox" interface that can be used from a period-appropriate terminal to play various musical selections.
