The sparcstation has 3 fuses (keyboard+mouse, ethernet, and SCSI)
which are the sidewise two-pin types you describe. The 3/50 has none
at all. It's hard to find the sparcstation fuses -- but there are
fuses of the same rating available in a small (resistor-style) axial
package, which you can bend one of the leads around and then trim to
fit, which make fair replacements.
