Data lines
by Mike Gordon
Adding the data lines
The eight data lines transmit ROM data between the PC and the cartridge. As described in the Components section, an 8-way commoned SIL resistor (47 kohms) is used to "pull down" the data lines to Ground.
SIL Resistor (8 way 47kohm with common pin)
Orient the resistor so that the GND (common) pin is in 7AL, and pin 8 is in 7AD. Solder all 9 pins in place.
Wire links
Solder in the following wire links:
36S - 36AK
35R - 35AJ
30P - 30AI
29O - 29AH
28N - 29AG
22S - 22AF
23P - 23AD
23O - 23AE
Progress so far...
Here's what the SMSReader should look like now:
