[net.unix-wizards] UNIX on PDP 11/24?

jbn@wdl1.UUCP (John B. Nagle) (10/15/84)

     Anyone running UNIX on an 11/24?  We are thinking of using one in a
dedicated no-users application?  Questions are:

	-  how big is the minimal V7 kernel?
	-  any hope of running an overlay kernel?
	-  any hope of running system V?

We don't care how slow it is.   We just need a minimal UNIBUS machine.

I'm running 2.9bsd on an 11/24 and I like it.  Here are the sizes of
the distributed kernel (xpunix) and the kernel I'm running now (hkunix).
Our system has only the following devices:  2 RK07, 1 RK05, 1 KL11, and
1 DZ11.  This has allowed us to reduce the size of our system somewhat.


	% size xpunix hkunix
	text	data	bss	dec	oct

	15872 +	5254 +	13406 =	34532 =	103344	xpunix
	69248 total text, overlays: (8064,7936,7104,7616,7808,6784,8064)

	15744 +	3454 +	13504 =	32702 =	77676	hkunix
	54656 total text, overlays: (8128,7872,7424,8128,7360)


In order to run 2.9 on an 11/24, it must be overlaid.  It's rather fast,
though, considering the hardware involved.  In order to get 2.9bsd, you'll
need an AT&T SYS V source license.
