I got the power cord for the microvax 3800 in the mail today. I checked the
fans as someone suggested, they Spin nice and smooth. I Iooked over
everything, nothing seems out of place. I powered the machine on. Very
quiet. I expected it to be much louder.
I turned the machine on and nothing explode
"So a 9-track open-reel SCSI drive should work just as well as a DDS, DLT,

Oh wow. i had not even considered that. I have a pdp 11 with a beast of a 9
track tape drive in is's own rack, that would be interesting if i could get
a scsi tape drive for the vax and use some big tapes to mov

That, at least in theory, is the great thing about SCSI--it doesn't

Connecting a scsi dlt or dat drive is something i had not considered. I
thought i would have had to buy and use DEC branded tape drives.
I already have a scsi dat and DLT drive in use on my SGI octane. I could

Same here--using an old system that's brought out only once every few

Hi Devin,
I upgraded my 3300 to a KA660 CPU and a CQD SCSI controller. If you
are patient, sometimes QBUS SCSI controllers show up on e-bay much
cheaper than the reqularly listed several hundred dollar ones. I
paid around $75.

Well that works out. I've got a couple Of dssi controllers now. Not sure
what that 50 pin cable could have gone to either. I have not opened the top
half of the machine yet.
Thank you for the pictures of where the battery are. I was looking on the
main cpu board itself. Ive yet to take that apart

Thank you for all the helpful information Glen. I will definately grab
that scsi interface when i get the funds, I have a scsi cd drive already to
be used with my SGi gear.
