archaeoIRC: How low can you go?

I'm still, on and off, tweaking this. I run it on my 5160 and have for a while. I'm just curious as to how low a config it'll still work under.

Particularly I'm wondering if (under DOS 2.x; any other is prolly too big) it is possible to run it under 256K RAM (it might be possible).

I routinely test IRCjr on a DOS 2.1 system with 256K. The footprint of the program is adjustable and is in the 140 to 160KB range. DOS 2.1 and the packet driver easily fits within the rest of the memory. DOS 3.3 works as well.

Yeah, the lowest-spec system I have has 640K. :/. The binary itself is slightly less than 75K but preallocates a lot of buffers, so I don't know if it'll fit. (and it is a little more complex than ircjr.)

As an approximate test on a system with more memory you could use int 27h or int 21h ah=31h (both terminate and stay resident) to allocate some of the 640KB so that there's less available to the system. I *think* both were available in 2.0...

When I made a program that did that (ate 384K), it worked with DOS 3.31.
