The Original Altair 8800 (First) microcomputer

The Original Altair 8800

 The Altair 8800, a groundbreaking microcomputer kit introduced in 1975 by MITS, was a pivotal moment in the history of personal computing. It inspired Bill Gates and Paul Allen to create the first BASIC interpreter for it, which later became the foundation of Microsoft.  


 It was the first commercially successful personal computer. Interest in the Altair 8800 grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines.

 The Altair 8800 computer was a break-even sale for MITS. They needed to sell additional memory boards, I/O boards and other options to make a profit. The system came with a "1024 word" (1024 byte) memory board populated with 256 bytes. 


The BASIC language was announced in July 1975 and required a serial interface board and at least one or two 4096 word memory boards, depending on the language variant.

  • 4K BASIC language (when purchased with Altair, 4096 words of memory and interface board): $60
  • 8K BASIC language (when purchased with Altair, two 4096-word memory boards and interface board): $75

MITS had no competition in the US for the first half of 1975. Their 4K memory board used dynamic RAM and it had several design problems.[37] The delay in shipping optional boards and the problems with the 4K memory board created an opportunity for outside suppliers.

Jamaica Gleaner Article on George Mitchell

Jamaica Gleaner Article on George Mitchell

Home > George Mitchell makes impact on air safety, years after near deportation to Ja  

 

Published:Thursday | February 20, 2025 | 12:06 AMLester Hinds/Gleaner Writer [1] 

He escaped being deported through the benevolence of a judge in Manhattan, New York in the United States (US), as well as an attorney with Catholic Charities in Brooklyn. 

Today, George Mitchell is making a significant difference in the safety of the airline industry, as well as Blue Origin space programme. 


“Nowadays, I review design documents and implementation to evaluate compliance against requirements, development processes, design standards and any industry standards to establish the level of compliance, documenting shortcomings and recommendations to achieve 100 per cent compliance,” Mitchell told The Gleaner. 


Mitchell is a senior real-time embedded safety critical systems engineer. His job is to make sure that all the systems – electrical and computer - on airplanes meet the standards of safety to take off and land. 


“Even the back seat television monitors on aircraft that you watch throughout your flight, I have to check to ensure that everything is fine,” he said. 


“I evaluate the artefacts, looking for weaknesses in design that might lead to incorrect fault detection leading to unmitigated failures.” 


He said the artefacts he needs to conduct his evaluation, from conceptual design to test results, are available in databases accessible from any secure location, allowing him to work remotely from his home office with some amount of on-site visits to the clients’ sites to audit certain activities (trust but verify). 


“I don’t work directly on the mechanical components, only on sensors that monitor their precise operation and the computer systems that evaluate the proper outcomes. Every conceivable event has to be anticipated and evaluated for accurate fault mitigation,” he said. 


EDUCATION 

Mitchell’s journey began in Higgins Town, St Ann, where he was born. He grew up in Fletchers Land (now Beverley Gardens). He attended Kingston Senior School and later Kingston Technical High School before attending The College of Arts, Science and Technology (now the University of Technology, Jamaica) on a scholarship provided by Esso. 

After graduating school, he worked for Aluminium Partners of Jamaica (ALPART), assisting in its start-up operation. From there, he went to bauxite company Revere Partners, which later closed in 1975. 


In 1971, Mitchell headed to New York, arriving on a visitor visa and intending to continue his studies. He enrolled at Polytechnic University in Brooklyn to obtain a bachelor’s degree in engineering. He was told that, by enrolling in school, he could apply to change his visa from visitor to student. This he did, but was denied. He appealed the decision but was again denied and ordered deported. 


“I had one semester to go to complete my degree,” he told The Gleaner. 

That is when the attorney from Catholic Charities stepped in to help. Going before the judge in a Manhattan court, the judge decided against signing the deportation order, providing he completed the last semester and returned to Jamaica of his own free will. 

He would complete the semester and return in 1975, but he was planning to return to the US to pursue his master’s degree. 


He received a full scholarship from Howard University but was unable to accept because his family was facing eviction from their Fletchers Land home. He took a job with the Jamaica Public Service Company and moved his family to Valentine Gardens. 


CROSSOVER 

During this time, he began taking flying lessons and was to complete the process of obtaining his pilot licence at Rutair Aviation. 


Mitchell returned to Polytechnic Institute on a student’s visa and received student loans so he could study for his master’s in management. 


On graduation, he headed to Los Angeles, California to join a micro-computer revolution that was just getting started. 


He told The Gleaner that, after spending several years developing computer hardware and software for the general computer environment, he crossed over into the avionics world of safety critical systems software engineering.

 

He was to start his own company in order to bring affordable data processing to small businesses, providing income tax preparation, general accounting, medical laboratory management and development of a verification and validation of safetycritical systems software. 


His work over the years has included working in the certification of Real Time Embedded Software for safety critical systems in avionics, including the planes on which we fly. 


“Recently, I worked as part of the audit team auditing the real-time embedded systems software for the first Blue Origin Rocket that was launched recently,” he told The Gleaner. 

Mitchell told The Gleaner that, in the US, the Federal Aviation Administration (FAA), the National Aeronautics and Space Administration (NASA), and SpaceForce manage the skies above the US and only certified crafts are allowed access. Mitchell’s job is to evaluate compliance before they are allowed in the skies. 


He is looking next to work on electric vertical take-off and landing aircrafts. 

However, even with all the critical work that he does to ensure that the skies are safe, he still finds time to give back to UTech where he is part of the mentoring programme. He is also looking, in partnership with other past students of Kingston Technical High School, to make a significant impact on that institution. 


“The Jamaican education system provided me with the tools necessary to reach where I am today, and the least that I can do is give back to the youth of Jamaica,” he told The Gleaner. 

So, the next time you fly, bear in mind that the safety system of the aircraft you are on, to allow it to take to the sky, might have been certified by Jamaican George Mitchell.
