I can’t stress enough just how awesome cd.textfiles.com is for finding ancient stuff!
I’m not sure why I started on this quest but I was looking for some old finicky DOS extender, and started hunting for Go32, the first DOS extender used by DJGPP. And for the heck of it, I wanted to find the first version, which I pretty much had assumed was lost to the mists of time.
Installation is pretty straightforward, however you have to use pkunzip for all the various old ‘methods’ of storing data in zip files, I found infozip leaves things out..
Also DJGPP 1.00 uses a LOT of environment space.. which is more so a problem for people running real MS-DOS on real machines.. (there are some!)…
It runs in DOSBox, but there is no doubt some stack corruption as trying to run things like dos edit result in:
But at least we can run more than one copy, or use a native editor.
GO-32 from this era is *NOT* DPMI compliant, nor is it VCPI compliant. And its based on GCC 1.39, which was a popular level with things like 386 BSD, although it seems early Linux used GCC 1.40 ..
For those who want to play, without the pkzip fun, I’ve slapped it into a single 7zip file. It’s not even a megabyte. But it was 1991, when 4MB of ram seemed like an incredible amount of memory!
