I don't wish to question authority, as it were, but the internal
cables are 104 pin (If I'm counting them correctly) and the external
SCSI port on the back is 72-pin mini-D. That *looks* like wide SCSI to
me! If it's not, then what kind of cabling is it? The ordinary
narrow-SCSI stuff I knew from back in the '80s and '90s was 50-way
ribbon cables with 50-pin IDC connectors internally and either 50-pin
Centronics or D25 connectors externally.
I have a VAXstation 3100 model 38 I bought on eBay for the princely
sum of ?0.99. Sadly it came without disks and I have no wide-SCSI
disks of <1GB.
?That machine doesn't have wide SCSI. ?It's 8-bit ("narrow") 10MHz.
As far as I
know you can't boot a traditional VAX from a disk of
<1GB... but could I put the core of VMS on a small slow narrow SCSI
disk, like an
80MB or something, and put most of it on the only Wide SCSI disk I
have, a 10GB...?
?You can use a sub-1GB disk to boot from, yes. ?Booting is, as I understand
it, the only restriction.
Also, I have several external SCSI CD-ROMs,
including 2 Apple units. I
seem to recall that VAXen want a weird block size, same as Sun kit...
is that correct? How would one tell if a certain drive could do this
or not? Is it a DIP switch setting or just a SCSI bus command?
?You need a drive that supports 512-byte blocks.
