That is theory. The practice is that you'll need quite a bit more than a 
286, although your machine should be fine.

You can ask Tree for a specially compiled version for slow machines. I 
expect that he doesn't like doing this any more (I run such a version on my 
20MHz 386), and it really still doesn't behave particularly well. With the 
stock build there are indeed delays at inopportune times (in S&P and CQ 
mode). These started happening when Tree changed the overlay structure a 
while back. I have often felt that the change was mistake -- I guess that 
it freed more memory, but it made the program unusable on old machines, and 
I have never been in a situation where memory was a problem, so I have a 
one-sided view of the affair.

I spent this past weekend using the stock TR build on a 33MHz 486 and a 
50MHz 486 at a fun multi-multi. Both machines displayed an annoying 
hesitancy at certain points in a QSO, but nothing like as bad as my poor 
old 20MHz 386.

The guess about slow disks may have something to it. My 386 certainly has 
an especially slow drive, so swapping bits of the program in and out leads 
to especially poor performance.

PS I think that in the next edition of the manual I shall add a caveat to 
the requirements, giving another set of specs that are the practical lower 
bound for CW contests on the stock build. Anyone any idea what those 
requirements ought to be?

PPS I realise that most people are running much faster machines and don't 
see any of these problems. For those of us using old hand-me-downs in the 
shackk, though, these are real issues, so it would be good for the manual 
to provide some practical guidance.
