All:
I'm longing to add a hard disk system to the Altair emulator. I came
across a 3-part series in BYTE (March - May 1983) for a host-computer
adapter manufactured by ASC Associates connected to a XEBEC-S1410 based
10mb SASI Winchester drive.
In part 3 of the article, BYTE printes the complete CBIOS, but the
article stops in the middle of the code around page 400 of the issue. I
have a nearly-complete series of BYTEs and I haven't found a reference to
the code in any subsequent issue.
So, here's the question...does anyone have a copy of the complete CBIOS
from the article *or* have a CBIOS for another XEBEC-based setup?
Any help is appreciated. Thanks.

If you send me what you have I can see about re-creating it but a better
idea might be to emulate the GIDE.
Howard Harte's SuperIO controller is another option and the full CBIOS is
available, it is extremely similar to the GIDE.
I may have some Big-Board II info around, it used the XEBEC-based
controller. In real life many found the Adaptec 4000 series to be better
since in real life it remapped bad sectors out and there was an RLL version.
