Megan asks:
Does anyone have any information on the KA630 CNF
board?
Only what's in the KA630-AA CPU Module User's Guide
Since I have never actually seen the board (which
plugs into the
KA630/650 directory), I'd specifically like to know what pins I
need to connect to establish the processor as the first, second and
third coprocessor...
On pages 2-7 and 2-8, it says that switches 7 and 8 of the KA630CNF
preform that function, and that they are wired to KA630-AA J2 pins 4 and 5,
which are called "CPU CD0 L" and "CPU CD1 L".
The switch settings are documented as
KA630CNF switch 7 8 CPU Operation Mode
KA630-AA J2 pin 4 5
Off Off Arbiter [normal]
On Off Auxilliary 1
Off On Auxilliary 2
On On Auxilliary 3
So I'd guess that if you grounded J2 pin 4, your KA630 would become
Auxilliary 1. Ground is available on J2 pins 1-3, 6, 12, and 16.
Other switch settings are:
KA630CNF switch 1 Halt Mode
KA630-AA J2 pin 15
Off Disabled
On Enabled
KA630CNF switch 2 3 4 Console Baud Rate
KA630-AA J2 pin 17 18 19
Off Off Off 300
On Off Off 600
Off On Off 1200
On On Off 2400
Off Off On 4800
On Off On 9600
Off On On 19200
On On On 38400
KA630CNF switch 5 6 9 10 Power-Up Mode
KA630-AA J2 pin 13 14
Off Off On Off Normal Operation
On Off On Off Language Inquiry Mode
Off On Off On Loopback Test Mode
On On On Off Manufacturing use only,
bypasses memory test
Notes:
According to the manual, other settings for switches 5, 6, 9, and 10
should not be used.
The manual lists switches 9 and 10 as being connected to KA630-AA J3 pins
3 and 8. However, I suspect that they are wired such that switch 9 when
off disconnects the normal receive input, and switch 10 when on connects
the loopback. I don't have prints to confirm this.
The diganostic LEDs are driven by J2 pins 7, 8, 9, and 11, with 11 being
the most significant bit.
+5V is available on J2 pin 20.
+10V is supplied from the BBU (battery) to the TOY (real time clock) via
J2 pin 10.
