DECtape archeology.

[Mattis Lind]

An update to this. It appears that with a git pull on my SimH repo clone
and subsequent make all of the disk images that boots on a real machine
(with TC boot ROM installed) also boots in SimH.

Runnicg FOCAL1 on D5.DSK give

.FOCAL1

.
?00 AT  0.00
*TYPE 1.0+3.0
=    4.0000*
*

So it do seem to do something right...
