While I was looking around at fleshing some stuff out on gunkies I came across this little nugget of MS-DOS history.
You can actually download 86-DOS the precursor to MS-DOS!Â And it even includes a bunch of SOURCE CODE!Â The best part is the awesome emulation suite SIMH can run 86-DOS!
Ok, for the first part of this, I thought Iâ€™d try my MS-DOS build of SIMH 3.81 which can be found on the sourceforge pages here.Â Because Iâ€™m using a 64bit OS there is no 16bit environment to kick start DPMI stuff, so Iâ€™m using the most excellent DOSBox emulator.
Thanks to the hard work of Peter Schorn, you can download the run able image for 86-dos right here, then simply point the Altair z80 emulator from SIMH to it, and youâ€™ll be running in no time.
To run it, simply point the z80 emulator to the boostrap file 86dos.Â Then just follow the onscreen prompts.
Then youâ€™ll be up & running!Â Notice how the prompt is different from MS-DOS, and yet how familiar it â€˜feelsâ€™.Â Also check out the commands!
Rumor has it that edlin has largely remained the same, up to TODAY on 32 bit versions of Vista!Â I havenâ€™t even verified it, but it would prove interesting.
I should also point out that Peter has amassed quite the collection of CP/M images, programming languages and other interesting stuff here.
