This is my main system. I took a
stand alone full height drive case and bolted to the
right side of the p-box which now houses a 40meg and
20meg hard drive. Drives 1 and 3> 5.25' 360k, drive
2> 3.5' 720k (used as a 360k) drive 5> 3.5' 720k
(used as 80 track for hard drive backup floppies) -drives
1&2 are in the p-box, 3&5 under p-box. This box
has been converted to a pc pwr supply and powers all
cards and drives (including hard drives)

On the left is the pc pwr supply before its
dis-assembly. Fan already removed from another supply is
installed. Arrow below fan points to hole where the new
ac socket goes. Not easily distingushable at the lower
left of the p-box frame is the on / off switch. This box
has the push button style switch. (you gonna put that big
brute in my unit????) |
| This is the TI pwr supply in all its glory. The
transformer alone weighs more than the entire p-box. I
have already removed the original fan (that thing
producing the low roar) as I'll be replacing it with the
12volt fan that comes with the pc pwr supply. (careful
man, that's my p-box your messing with) |

The new pwr supply installed with wiring complete.
The original wires that were on the bus board were
connected to the new supply with no splices. The original
floppy pwr cable was used as well. An additional pwr
cable was added that will exit the rear behind the
internal floppy drives. You can see these cables along
the rear behind the card bus. Note that the remainder of
the card cage was left off for ease of view (GOSH! will
the framework hold that monster????) |
| The pwr supply fully removed including ac socket and
bus socket board for the cards. For the pwr supply I'm
installing I had to remove the old transformer mounting
studs (circled in black) leaving one to secure the new
supply. The wire holder (with arrow pointing to it at
lower left) was removed as well. The original ac socket
on the right was too long and was replaced with the one
on left that came with new supply (with capacitors
installed). (geez man, I said CAREFUL! Look at my poor
old p-box now) |
