Interior Case Layout
Remove the Case
Just like the 8570, unscrew the three knurled screws at the
back (they will come free, they arn't captive), and slap and pul the top cover
to the front. After about 2 inches of forward travel, you can lift the cover
Remove the Planar
As you'd expect from a bunch of former IBM'ers, it's fairly easy.
Pull all adapters. Unplug the speaker, LED/Reset Switch Header, battery header,
pull the cpu card, remove the floppy and power plugs, pull the edgecard off
the DBA ESDI drive (leave the tape connector headers in the board sockets).
Remove the screws holding the planar in. To my suprise, ALL planar
screws ARE reachable with the PSU and hard drive in place. Remove the (outside)
mounting posts from the video, both serial and both parallel ports.
Now push the planar in from the port cutouts so they are inside
the case. Slowly pull the planar out of the case away from the power supply.
Keep the angle low because the BIOS chips have to fit in a cutout in the drive
The case is very well made for being a clone-tyoe.
Uses a Tadiran TL-5293/W, 6v lithium.
The floppy in a Reply 32 is a TEAC FD-235HF. Has seperate signal
and power cables. Uses the clone mini 4 pin power plug. 34 pin signal plug.
NOTE: The floppy header is poorly
marked. Pin 1 of the floppy cable is towards the outer side of the system.
Floppy Jumper Settings
Install / Remove Full Length Adapters
Open the case. At the front. notice the knurled nut? Unscrew it.
Pull the "hood" up, when it clears the post, pull the hood towards the rear
until it detatches from the case. There are NO further screws or other fastening
devices holding it in. Now full length adapters are free to be handled
LED / Reset Connectors (P15) Pinout
NOTE: When removing the LED/Switch
assembly from the front of the case, the screw that has the grounding conductor
attached is longer than the other screws. It has to be long enough for the
terminal ring and nut to fit on it as well.
NOTE: When attaching the LED/Switch
header, note that two positions are empty on the plug. The two empty positions
go to the left of the pins. The black wire goes to Pin 1 on P15.
Uses the same two rectangular plugs like AT class systems. Remember,
when plugging in the headers, the black wires on the two plugs are to the
center of the header.
Power supply is Delta Electronics SMP-200JB, 199.1Watt (not BobWatt, either)
100-120v @ 6A / 200-240v @ 3.5A 47-63 Hz
NOTE!!! The PSU is NOT AUTORANGING! To switch between 115v and 230v,
you MUST use the slider switch between the AC plugs at the rear of the case!
NOTE DO NOT switch between
115 and 230 while the system is on. This will destroy the PSU.
+5v @ 22A
-5v @ 0.3A
+12v @ 7A
-12v @ 0.3A
On the interior front side of each Reply32 is a aluminum cased, finned
power resistor. There are three 5.25" drive power connectors in the Reply32,
two are only long enough to reach the internal 5.25" bays in front of the
case (opposite the PSU). The third 5.25" power lead reaches over to
the front, right side of the case and connects to a connector that goes
to the power resistor.
Dale RH-25, 25v, 30 ohm, 1%.
