Zane,
re: Ctrl+Alt+Ins combo and a question.

This is standard feature in Zenith's all the back to early 8088
up to early 486's machines before Zenith got eaten twice once by Bull
Groupe then once by Nec/PB (yuk!).

That CPU daughterboard ones always has SIMM slots and has
IDE/FD/Video on board as standard feature except for early LP 286 has
one video card in one of the 3 slot. Those cases are all breige, 3
slots, has real lock in rear to lock the case along with external U
loop to keep the pc from wandering from the desktop (too secure!) and
height is more like 4" high or plus one HH if it has a 5.25" bay and
has 5 slots. The FD and IDE is on same slot card. The I/O is on the
motherboard usually. The PSU switch is little neater recessed rocker
in a countersunk bezel on right side towards back.

The older pcs starting with 8088 and early 286's used 3 5.25" HH bays
in one cage and a large power cube behind it, all are passive slot,
used 3 or 4 taller special size brackets for the needed processor,
memory and i/o w/ video combo. Top shell is light grey, base is
painted black. I have not seen 386dx's in that type of case because
I recall that passive slot board has space for that and it has also
mounting hardware to support the 32 bit portion. The power switch is
plain-jane narrow black rocker with a white dot on back in PSU area.

The 386dx and EISA ones used wider version of classic 8088
type case (similar to AT case) but the two 52.5" cages are removeable
by one screw each. Dunno on 486 in that case type.

Which one we're are now talking about: newer one or the older model?
