The 2-trans ALDL cable is simple to do, and wont need a +12v power source, here are the schematics	Schematic		1. Solder the transistor leg (E) together with 2 100kOhms resistors into TxD(3)	Step 1
2. Now solder transistor leg (C) together with a 10kOhms resistor into TxD(2)	Step 2		3. Now solder the loose end of the 10k resisor in step2 into DTR(4) TOGETHER with a 27kOhm resistor	Step 3
4. Now take the loose end of one of the 100k resistors in step1 and solder it to the transistor (B) in step 1 TOGETHER with a new 100kOhm resistor	Step 4		5. Now add the diod onto the loose end of the latest added 100k resistor (Step 4)	Step 5
6. Now solder the loose end of the last 100k resistor in step 1 on to a new transistor (B) and place in like the picture shows	Step 6		7. Now solder together loose end of diod and the 27kohm resistor to the (C) on the latest added transistor, dont cut the (C) leg on the transistor yet.	Step 7
8. Solder a wire into Gnd(5) together with (E) on the transistor and loose end of the 27kOhm AND a 10kOhms resistor. This wire is to be connected to ALDL pin A	Step 8		9. Now solder a wire to the point where the diod/trans/res is soldered together, this wire goes to ALDL pin M	Step 9
10. Solder a wire on to the loose end of the 10kOhm resistor, this wire goes to ALDL pin B	Step 10		11. Put the whole package into a small box........	Step 11
