DTC-510B controller

[Roberto Bazzano]

Hello.
I'm trying to replace a Xebec S1410A SASI controller with a Data Technology 
Corp. DTC-510B or DTC-510A, for a old homebrew computer 
(http://www.z80ne.com)

The problem is that, even if the controllers should be "almost" compatible, 
the DTC-510A/B doesn't work (while the Xebec works fine).
I'm not able to find any manual about it, only some dipswitch settings.

Perhaps has someone a user manual for DTC-510B (and DTC-510A) so that I can 
compare commands, configurations, etc. with Xebec S1410A?

Thank you very much.
