I hate to say it - but back in the old PDP11 days they had overlays.
And learned to like them.
     
And we walked 50 miles to school, uphill, and we didn't have shoes then...
8-)
     
There is some satisfaction in shoehorning the most functionality in to
the smallest space.  The amazing fact that a PDP11 could multitask
with the same 64k of memory that ran CP/M was amazing to me.
     
I grew up with PDP11's and love the fact that RT11 can run foreground
and background tasks (up to 15 background tasks) in a machine with only
64kb of real memory is a fact that some people that haven't had to live
with those restrictions don't understand.
     
Unfortunately, you can't run X in that space, or NFS... Perhaps TCP/IP
though...

Organization: Rick's Home-Grown Un*x

I'm somewhat bemused by the Minix vs. Linux et seq. threads,
but there's something I'd like to (belatedly) say.
To start with, there's still at least one person (me) for
whom XT-compatibility is still an issue.  I'm interested
in the OS design issues, too.  But the main reason I bought
Minix was to specifically learn about Unix.  That's one
point I haven't seen anyone else make.  
 
Thanks, Andy.

Can someone please help me with details of an XT MFM hard disk controller?
I have the port addresses and (I think) the commands and error codes, but
I'm after a little more programming info. I've also got one reference, the
Minix XT driver code, but it's not very well documented.
     
So, anyone know anything about these beasts?
     
BTW: I know the hardware is obselete, but I gain 120 meg for "free" if I
can write a driver for it for Linux, and what's more, the card coexists
quite happily with my IDE and SCSI drives!

My first question is, are sockets supported in MINIX ?  My next question is
, can a driver be written for a networking card under MINIX and then have the
two cards be connected and operate as a LAN ?
     
Thanks in advance

Can someone please help me with details of an XT MFM hard disk controller?
I have the port addresses and (I think) the commands and error codes, but
I'm after a little more programming info. I've also got one reference, the
Minix XT driver code, but it's not very well documented.
     
So, anyone know anything about these beasts?
     
BTW: I know the hardware is obselete, but I gain 120 meg for "free" if I
can write a driver for it for Linux, and what's more, the card coexists
quite happily with my IDE and SCSI drives!

It was the timing loop governed by PNK_DELAY that had to be lengthened because
the 2nd disk is a fair bit slower than the first. PNK is presumably an acronym
for Parameter Not Known, it was pure hocus pocus finding a useful value for it,
and it was quite critical timing. Anything less than 140 or so discarded the
interrupt, values between 140 and 160 gave a "kernel panic: Winchester task got
message from -1". 160 worked alright. The first disk (which needed the OLDSUPRA
mod in order to boot without a kernel panic) really didn't care about the timing
delay and worked perfectly with all values that I tried, from 0 to 200.

I wonder, with the wide variation of CPU clock speeds available these days, is
there not a better way of handling timing routines than using software loops
written in C? Surely there are some spare timers on the MFP and sound chips
that can be used to advantage. A lot of time is wasted executing busy loops
while disk transfers are taking place, and this is a DMA based system (!!!).
During the actual transfers, everything else just hangs. At least it is
working now :-)
