<Duh? What do you mean "didn't" support SCSI? Since when did support for

Int eh specific sense that unless the device fakes a know device like
a CMD200 scsi adaptor to name one the boot roms may not be useable.

<The answer should have been; Yes, you can have a SCSI-controller on the

In some sense you could with the above caveat. 

<Digital didn't have any SCSI controllers for a lot of years after this

<you *could* have a SCSI-controller on the machine. Nowadays both CMD, DE

Ok, I'll sign on for that.  However they don't specifically have SCSI for 
MICROVAX-I.  Thats a NIT as most vendors if asked would about using it 
with micorvax-I would likely answer "there was a microvax-I???".  Because 
it was Qbus... well it it fits it will likely work. ;)

Of course putting more than 4mb is impossible and all the other goodies 
will likely melt the PS (or atleast the connector cable if it wasn't 
refitted).  Persuing getting it running is purely for historical reasons
if only becuase it was so slow you will be history waiting for results.

I know I ran one for a while it was slow compared to a 730!
