TCDEVPLUS (but not the TCDEV) also includes 14-way ribbon cable connects to the
TP400 J5 connector, making connections for COM3 and COM4.
The TP400 includes its own VGA, floppy and IDE disk controllers, and VGA, floppy
and IDE disk controllers are also present on the TCDEVPLUS. It is possible to use
either the VGA and disk controllers on the TP400 or the controllers on the
TCDEVPLUS (though not a mixture of both). These instructions assume that the
VGA controller and floppy disk controller on the TCDEVPLUS are used initially, as
this will be more convenient during early stages of development. Users can move to
the TP400’s on-board disk and graphics controllers as the development process
progresses.
The next two sections describe using the TCDEVPLUS and the TCDEV with the
TP400. Note that the old REV B TCDEV cannot be used with the TP400. The old
REV B TCDEV boards can be identified by having only one site for PC/104 boards,
and only one power LED.
1.6.2 Using the TCDEVPLUS Development System
To use the system, first install an SDRAM SODIMM module into the TP400 SDRAM
socket, observing its polarity, and observing proper anti-static precautions. The
SODIMM socket has a lug that engages with a cutout on the module, which prevents
incorrect installation.
A fan or heatsink should be added to the TP400, as it may get too hot without one. A
heatsink is supplied as part of the TP400PAK starter pack (see Appendix D for
details).
Enable the floppy disk controller and VGA graphics on the TCDEVPLUS. This is done
by setting the jumpers at jumper areas E3 and E5 to the "EN" position. Disable the
IDE disk controller on the TCDEVPLUS by setting jumper E4 to the “DIS” position.
The TCDEVPLUS COM4 UART should be disabled at E8. The battery back-up
jumper should be set in the BATT position at E2. The status LED jumpers at E7
should both be set in the 1 - 2 position. At jumper area E6 set the C000 jumper to the
"EN" position and the other seven jumpers to the "DIS" position. The speaker should
be enabled by fitting a jumper at E1. The GCAT486 printer should be disabled at E9.
Jumpers should be removed from E10 and E11.
Plug the TP400 onto the TCDEVPLUS and connect the 50-way and 14-way ribbon
cables from J4 and J5 of the TP400 to the corresponding connectors on the
TCDEVPLUS. Ensure that pin 1 of the TP400 connectors go to pin 1 of the
TCDEVPLUS connectors. Failure to connect the 50-way cable correctly may
damage the equipment.
Connect but do not switch on the TPPSU. (Note that the TPPSU power connector is
polarized. Ensure that the locking tab on the power supply cable mates with the
locking tab on the TCDEVPLUS connector). Failure to connect the power supply
cable assembly correctly may damage the equipment.
Connect the keyboard and VGA monitor to the appropriate connectors.
Insert a bootable floppy disk into the TCDEVPLUS floppy disk drive and switch the
power supply on. The computer should begin booting. You may press the F2 key
