Is there a RAM disk for 4.2 BSD ???

From:      Mike Muuss <mike at BRL-TGR.ARPA>

BRL has 2 VAX systems with RAM disks, on is a 780, the other a 750,
both running 4.2 BSD.  We use the Dataram BULK MOS product,
which emulates an RF-11 head-per-track disk;  we did the driver
ourselves (it's availible).

Advantages:  No head motion for /tmp

Disadvantages:  The UNIBUS is busy enough without this stuff too.
Transfer rates are generally less than what a MASSBUS device could do.
Given the cost of the bulk mos device, you are better off buying
more moving head disk drives and putting /tmp & some archival stuff
out there (assuming you add MASSBUS disks).

Best,
