Before I ebay buy a monitor, original IBM 5135, will it match the scan rates of
the IBM of the IBM Professional Graphics Controller?
I wanted to keep this system looking all original IBM.
Will I need a different monitor, Princeton or something like that?
Your recommendations appreciated.

Doesn't have to be strictly a MIPS Magnum R4000, just a MIPS R4000 ARC
box! Can be a Magnum, a Deskstation, NeTPower, Pica, any of them
really.

You really do need SMART monitoring on solid-state storage
which may or may not exist in the adapters. SSDs will silently
fail if they run out of sectors to write to.

About 20 years ago I rescued a fully working Sun SPARCstation LX with CDROM
and QIC-150 tape drive - all 3 in lunchbox format - plus monitor when we
moved office and management decided they no longer wanted/needed it.
Shortly after I have installed an early version of NetBSD (1.3.3) from the

newer version of NetBSD on it than was already installed. The stack of 3
units was stored in a museum grade glass display cabinet. Sadly all 3 units
