10 CPC-2400 User's Manual
2.2 Floppy drive connector (CN11)
You can attach up to two floppy disk drives to the CPC-2400
on-board connector. You can use any combination of 5.25" (360 KB /
1.2 MB) and/or 3.5" (720 KB / 1.44 / 2.88 MB) drives.
The card comes with a 34-pin daisy-chain drive connector cable. On
one end of the cable is a 34-pin flat-cable connector. On the other end
are two sets of floppy disk drive connectors. Each set consists of a
34-pin flat-cable connector (usually used for 3.5" drives) and a
printed-circuit-board connector (usually used for 5.25" drives). You
can use only one connector in each set. The set on the end (after the
twist in the cable) connects to the A: floppy. The set in the middle
connects to the B: floppy.
2.3 Parallel port connector (CN1)
The parallel port is normally used to connect the CPU card to a
printer. The CPC-2400 includes an on-board parallel port, accessed
through a 25-pin DB-25 connector. The parallel port is designated as
LPT1, and can be disabled.
2.4 24-bit LCD display connector (CN2)
CN5 is a 40-pin dual inline header and is used to connect an LCD
display to the CPC-2400. The CPC-2400 has bias control which can
be used to control the LCD signal voltage. Pin 7 of CN2 is for LCD
contrast adjustments.
2.5 36-bit LCD display connector (CN3)
The CPC-2400 supports 36-bit LCD that must be connected to both
CN2 (40-pin) and CN3 (20-pin).
The pin assignments for both CN2 and CN3 can be found in Appendix
A.
