86-DOS - An Early 80's Operating System

In this video I do a review of 86 DOS (AKA QDOS) which is an operating system originally designed for Seattle Computer Intel 8086 machines. 86 DOS was later purchased by Microsoft and extended into MS DOS.

right, it's absolute bizarre that you could wipe the entire OS with one word and a 'y'. Sure, same with with rm -rf, but clearly there is a greater hurdle to that. It would also have a much greater impact, since you probably paid good amount of money to get your hands on a floppy with this in the first place.

MS DOS wasn't the first successful home computer OS. 86-DOS was an almost identical clone of Digital Research's CP/M, which was already a huge success on older computers. So much so, that DR sued MS over it. In fact, CP/M almost became the default OS supplied with IBM's original 'PC'.

@@scallen3841 The story that Gary Killdall went flying instead of meeting with IBM's rep is untrue. The simple truth is that D.R. didn't like the contract IBM asked for; and brand new company Microsoft (known for MS basic, one of the most popular programs running on CP/M) bought 86-dos from Seattle computer products and resold it to IBM. Also unfair is the suggestion that Microsoft cheated Tim Patterson when they bought 86-dos. They hired the guy (both as an employee and contractor), and he did much better working for Microsoft than as a small hardware manufacturer who... um... would soon be crushed by IBM. --- The odd thing is that if DR had already released cp/m 86 -- Patterson would never had needed to write a work-alike OS for his computer line.

My first computer was a Heathkit H-89 I built in 1980. It came with 8k of memory (The maximum was 48K) which was enough to run H-DOS, but I had to add another 8k (cost $75!) to run MS-DOS. It had a single floppy drive (100k unformatted) which doesn't sound like much, but you could install the WordStar word processor on one disk and have enough room left for a two page letter.

11:02 COM is indeed short for "Command" BUT in reality in DOS there are 3 type of executable files with extensions: BAT, COM and EXE. Difference being: BAT files are scripts (like bash scripts), you can create one/open/edit with a text editor like EDLIN (which stands for EDit LIne because it was a line-based editor) and a BAT file, still to this day is just a set of command-line commands you execute in the shell (DOS). EXE files were later developed and were a bigger in size , than the COM files. They had also different file signature (first bytes in the file). A C or Pascal program would produce an EXE file after compilation. From what I remember the COM files were smaller and coded in Assembly (could be wrong).

I'm pretty sure that most users in 1986 wouldn't have a 3 1/2" 1.44 MB disk drive, since it literally just came out that year. The 5 1/4" disk at 1.2 MB was probably more likely - and that was an actual floppy disk. I remember, since the computer my family got in 1992 had a 5 1/4" drive as well as the 3 1/2" drive. I'm too young to remember, but my perusing of old text files has taught me that owning multiple disk drives wasn't necessarily all that uncommon in the early and mid 1980s. If you were messing around with 86 DOS, I think chances were pretty good that you and more than one drive. SysOps who were running bulletin board systems needed multiple drives, for example, to keep things up and running. EDLIN is the compromise we need in the VIM - EMACS debate.
