I just restored a Heathkit H8 and H17 and have problems creating a boot diskette on the H17.
The H8 has a pam8 ROM monitor and the following boards: H8-16 RAM, H-8-2 PARRALEL I/O, H8-5 SERIAL I/O and the controller board.
All tests in H17 manual have passed successfully, the rotation speed of the drives are set.
The Serial I/O does communicate with my terminal emulator sw.
I downloaded Dwight Elvey's Disk Image Transfer Program v9 and started to follow the instruction (great tool and instructions!)
I was successful in creating a Boot Image Transfer disk and can use it to communicate with H89TRANS on the DOS machine.
I can also Open an HDOS h8d file and write it to the H17 disk. It steps to track 39 and returns to the H89TRANS menu.
But the created diskettes won't boot HDOS? When hitting GO at PC 030 000, the disk start turning, the address digits change and after a few seconds halt at 037 127
I have used old Northstar hard sectored diskettes, because I don't have any new ones.
Then I lowered the baudrate to 2400 to see if that would give better results, but same behavior.
Maybe I should try a different f.i. TANDON drive instead of WANGCO 82 drives in the H17?
2 Remarks:
When trying to read-back a created HDOS diskette to a new file for compare, using H89TRANS, it halts after displaying 42 42 after the R.
When checking point 4 under Debugging, my DE register does not show the values as in the instructions.
Thanks, Wilko
