[net.micro.pc] Rumors

* The New York Times reported in the September 2 edition that
  there were rumors that IBM would wait until 1984 to announce
  the Peanut.

* The September-October PC Tech Journal reported rumors that IBM
  was working on an OS upwardly compatible with some of their
  mainframe OS's. PCTJ also reported rumors that Tandy (TRS-80)
  is going to make an IBM-compatible priced under the other
  IBM-compatibles.

	Recent rumours suggest that Microsoft made use of Intel reserved
	vectors in PC-DOS and the new 80188 makes use of these vectors.
	Thus old software using these vectors will bomb out.  Some suggest
	this is the reason for the delay in the IBM PC Junior (Peanut) which
	is probably based on the 80188.

I am amazed that people submit articles with 'rumors' without even  bothering
to read *any* of the relevant documentation.  In the IBM technical reference
on page 2-4 IBM lists all of the interrupt vectors that THEY use and/or
reserve.   These are in the range 0-1F.

On page 2-7 of the same document, IBM lists the DOS vector assignments as
being in the range 20-3F.

In *any* reference on the Intel 186/8 they list the vectors in the range 0-1F
as being in the Intel reserved range.

The other 'rumors' are mere corollaries of this misapprehension.
