While reverse engineering the BIOS, Gordon tells Joe that they will need to read 65,536 hex values. Assuming that they read a nibble (4-bits) at a time, this implies a 32K ROM BIOS. But the PC BIOS was stored in an 8K ROM. So they only had to read 16,384 nibbles. There was another 32K of ROM, but that contained the BASIC interpreter which they could license from Microsoft.

"Halt and Catch Fire" (HCF) was NOT a command that set up a race condition. It was a mythical command to do this.

When taking apart the IBM PC they are shown desoldering a chip, but the chips are push in.

When programming Mutiny on the C64, the code has both Linux and Windows commands in it: init C:\community

Neither of these commands would do anything on a commodore.

The use of the phrase "your face has been on a milk carton" when at that point in time, no face had yet been on a milk carton (the first was in December 1984).

The electronic circuit built to decode the IBM BIOS ROMs uses 6 white LED. White and blue LED were only invented/discovered after 1995.

As Clark and his kids are leaving the movie theater where The Return of the Jedi is showing (1983) they discuss going home to watch the first two films (in the Star Wars Trilogy). The Empire Strikes Back was not available on home video until 1984.

5mm Clear Multi-Color LED's did not exist in 1983.

The scene of Downtown Dallas showed the incorrect skyscraper design or buildings that didn't exist.

The Renaissance Center in the middle next to the taller skyscraper under construction wasn't renovated with glazed windows in new crisscross pattern until 1986.

The taller skyscraper under construction, originally named InterFirst Bank building, was shown as an elongated hexagon shape. In reality, the skyscraper is actually square. The construction started in 1983 and was completed in 1985. That building would not have been almost completed as shown in the episode in 1983: it would show twenty or less floors of metal frames.

All of the cars have California license plates, even though the series is set in Texas.

Gordon attempts to reverse engineer the BIOS but first must figure out which chip it is. Hint: it's the EPROM marked Copyright IBM 1981. This would not have stumped any Computer Engineer of that era.

Gordon manually steps through and transcribes the BIOS contents from an EPROM. This is a very error-prone process and completely unnecessary (aside from the source having been published by IBM) as companies such as Data I/O had EPROM readers readily available at the time. It would have been a simple matter to unsolder the EPROM from the board, insert it into the EPROM reader and gotten a complete hex dump of the contents.

It has been pointed out that Gordon misreads '1101' as hex digit 'B', when it is in fact 'D'. One suggestion is that the LEDs might have been upside down. This is not the case as he correctly reads the next digit '1110' as 'E'.

When reading the first two hex digits from the BIOS PROM, the first digit is 1101, which he incorrectly interprets as a B, when that is actually D. Although the LEDs could have been shown upside down in which case they would have read as 1011 (which is a hex B).
