 I have a couple of bits of information for LDOS users. First, I
have found a bug in LDOS 5.1.3.  In my copy, the SVC table has an
error. All SVC calls with codes of 75 and above caused a crash.
I called Logical Systems and got the location of the table in
sys7/sys. It was an easy patch to do. If anyone out there has
had trouble with the SVC calls in LDOS let me know and I will
mail the patch. I have a later copy for my MAX-80 and it does
not have the bug. So unless you have an older copy of Model I
LDOS, I doubt you have a buggy copy. The easy way to fix it is
to order an updated copy. They are after all only $10. 
 And now some good news. Version 5.1.4 is slated for release at
the end of August. Anyone getting ready to buy an update, may
want to wait till then.
 There is also some bad news. Work on Version 6 has been
suspended at Lobo's request. I called Lobo today to find out
why. It seems that Lobo is in the middle of some changes in
their incorporation status and did not wish to commit money
to large projects till that was finished. They assured me that
work on Version 6 of LDOS would be started again in a couple of
months. Also please note that there have been some personel
changes at Lobo and some orders have been lost. If you placed
an order in the first half of June and you don't have it by
mid August, it might be a good idea to give them a call and
check on the order. There is some good news however, the MAX-80
is now being shipped with CP/M 3.0. So everyone who has been
waiting for it, your wait is over.
 Finally a couple of side notes, Logical Systems user service
phone number has been changed. It is now 414-355-5454. They also
tell me that Version 6 will never be written to run on machines
without 64K RAM. So if you have a Mod I or Mod II without mappers
you will be stuck with Version 5.1.x. At least with the SVC
calls, you can still write assembly programs that will run
under Version 6.
