Hi All,

It was possible to solve the issue with much help from Jerry and Paul.

1. Bootstrap Loader as printed in the Dilog Documentation is wrong and was fixed.

Here is the fixed and running version:

Device name = MS New =
Beginning address = 001000 New =
Last byte address = 001400 New =
Start address = 001000 New =
Highest Unit number = 1 New =
Device Description = TSV05 New =
Enter ROM ODT

xxxxxx/ = open word location xxxxxx if address even, byte if odd
RETURN = close location
. or LF = close location and open next
- = close location and open previous

2. The issues I had after the Bootstrap was fixed where related to my cable, where I had overall three Pins with bad/no contact depending on the cable movement.

Extended Status 0 at 001124 seams to be OK, as 000310 can be mapped to: motion, 
on-line, phase-encoded drive
Extended Status 1 at 001126 seams to be not OK, as 1 means read data Parity 
error

Related Pin's:
Connector P1: 14
Connector P2: 8, 32


So I'm quite happy to have a running Pertec 1/2" drive.

Again many thanks and Greetings
