not expect any feedback, this is not a program, this is a direct communication with the controller via in/out instructions. The ll-format process is done in the controller's firmware and the Xebec-controllers are very slow. -- Martin Peters mar...@shackspace.de

Documentation for Xebec Owl (a 1984 SASI-disk-drive)

2019-01-10 Thread Martin Peters via cctalk
Anyone here, owning a Xebec Owl and/or its documentation? The Owl is a SASI-disk-drive from 1984. One could say that it's mostly a Xebec S1410A mounted on a drive, thus eliminating the ST-506-interface. The one I had my hands on seems to be a late version, called the Owl II (20MB instead of 10MB).

HP in a newer revision of the board. And if not "only", I think the dumps would be helpful anyway. It would be great if you could do a dump for me :-) Many thanks, Martin -- Martin Peters mar...@shackspace.de

2016-05-21 Thread Martin Peters
Hello, the EPROMs are labeled 07595-18045 and 07595-18046. Can anyone do a dump for me? It's really urgent. Our local hackerspace wants to get rid of it, if there is no chance to get the Firmware again. greetings, Martin
