SPAREprinter model QA-6, anyone know how to do a self
 print test on this unit I can not find any buttons or anything; 
 It will not do much unless you have it connected to a SPARCstation
 running NeWSprint. The SPARCstation also requires a special S-bus card to
 interface to the printer.
 In other words, you have either a worthless printer, or a good excuse to
 go get yourself a SPARCstation. 
 
Oh, come off it!  Surely there must be some way of finding out the
protocol and building an interface and/or writing drivers for another
machine!
Which reminds me - I have a couple of Diablo 630 printers with ECS
daisywheels which have strange edge connectors on the back.  I am told
this is a Qume Sprint 3 interface - has anyone got a technical spec.?
Philip.
