Default TP "pins" in the A1200
Hello ppl.

Can someone tell me the pinout assignment in the TP9 and TP10
connectors inside the A1200?

Thanks in advance.

Example: the two leftmost "pins" on TP9 are good to add a hard reset push-button to the A1200.

I just want to know the assignments of the other pins.

A lot of times "TP" locations are test points. I am not sure in this case though. Try looking at the board schematic and see if it gives a clue.

Yes, they are test points, indeed.

But the schematics don't show them.:-x

So I have to ask...

Well, the R2 schematics do show the TPs:

TP1:

2-_AS
3-_DS
4-R_W
5-_DSACK_0
6-_DSACK_1
7-_ROMEN
8-_CDIS
9-_KB_RESET
0-GND

TP2:
1-CCK
2-CCKQ
3-_RAMEN
4-_REGEN
5-_BLS
6-_OEB
7-_RAS
8-_CAS
9-_DWE
0-GND

TP3:
1-_DBR
2-RGA8
..
9-RGA1
0-GND

PS: Sorry, read something like TP2...
Er, where is TP9?

No, you are right, that's my mistake! The right names are TP1 & TP2.

Thanks a lot for the pinouts!

Somewhere in the future: new cool hacks!

The easiest trick is route a pair of wires from kb_reset and GND to a push-button in order to make a hardware-reset button to your Amiga.

Very useful if you make your own keyboard adaptor and the <CTRL>+<L-Amiga>+<R-Amiga> don't reset the Amiga anymore (good hack to towerised Amigas too).

Nice to know, I need to make reset button. Where are these pins? Is there a pic around somewhere?

Oh, nevermind I found them here:
