"Forbidden Planet" was set on Altair 4 which would usually mean the 4th planet orbiting Altair counting outwards. Likewise Earth is sometimes referred to as Sol 3.
I think the Star Trek planet was another number presumably orbitting Altair. Given the size of the brightness at the end of "Forbidden Planet" it would have to be much further out or in a different fictional universe.

I think after the first 30 or so bytes the loading process would get tiresome, particularly if you had nearly finished $ someone kicked the power plug as happened at Steve Dompier''s famous demo.

Ha! The name Altair came from the great sci-fi movie of the 1950''s, ''''Forbidden Planet", starring Leslie Nielson. Evidently Mr. Roddenberry was a Forbidden Planet fan as well!

I had an early Altair bought as a kit from Dick Heiser''s computer store in Los Angeles, had it in my Winnebago motorhome with a LS 7700A terminal.

On a trip around the US in the motorhome, I bought a second dynamic 4K card from Bruce Seals (later to become Seals Electronics - another story) at his Knoxville, TN Byte Shop. The card didn''t work, stopped at MITS in NM on the way back to California, they showed me their repair facility and said that I could leave the card to be repaired if I wanted, said "no thanks" after seeing the 50 or 60 card pile awaiting repair.

I fixed the card myself, finding the refresh timimg was off, they used one-shots to time the refresh, with poor timing components. It took a dual trace scope and careful comparison against my working 4K card.

I used the Altair for many years, toggling in the bootstrap loader for the basic loaded from cassete tape.

In 1975 When Bill Gates and Paul Allen Got their lates copy of Popular Electronics With The Story about the Altair 8800 they realised that this was what they were waiting for, they started a new company soon after called Micro-Soft

I built the IMSAI 8080(A) in '76. It took 4 months and cost $625 at the time. I sold it in 1980 after upgrading to text video (TV) and 1K ram for $800
