I don't remember much about these, but I do recall a "stand" shaped like this: ___ _| |_ (fixed-width font required of course) ...that the drive mounts atop, and then underneath that would be one of the various SCSI<->QIC-02 or QIC-36 adapters for the tape drive. A hard drive mounted on its side, either to the left or the right of the tape drive, I don't recall which. The hard drive would be a 5.25" FH device, either native SCSI, MFM via an Adaptec ACB-4000 SCSI<->MFM adapter, or ESDI via an Emulex MD-21 SCSI<->ESDI interface. I'm pretty sure I have at least one of these boxes. If I run across it I will take pictures of the innards. -Dave On 4/6/19 8:42 AM, Glenn Roberts via vcf-midatlantic wrote:

Certainly looks like the external box I had attached to my Sun 3/110 way back in the day. We also used these on the 3/60s. prior to the "pizza box" form factor Sun had external drive units. As I recall these had a disk drive and quarter inch cartridge tapes for backups. Never cracked one open so don't know much about mounting devices inside..

Hi, All,

I'm dusting off old Sun gear for VCF East and I ran across a shell of a Sun 511 box on my shelf. Unfortunately, I can't seem to find any docs online about what would have been stuffed into it back in the day. Lots of Sun info still out there but the 511 box is not well represented. I suspect that's because I think it's a late Sun 2/early Sun 3 device.

The best description is here:

Mostly I'm curious about mounting plates/brackets, etc. I don't have the original PSU so if I use this box, I'll have to find something modern anyway.

I also have some more modern (late Sun 3/early Sun 4) tape/disk shoeboxes. I haven't found any pictures online but they are tall enough to hold a full- heigh 5.25" disk over a 5.25" half-height tape drive on a half-height bracket with the PSU to the rear. Those are ready to stuff with disks so I'll probably start there.

If only I had more than one DD50-P Sun SCSI cable...

Alas, the "joy" of vintage machines, when it's hard to find parts that fit.
