Hi,
I have connected external power and a keyboard to my PAL DTV without problems, however I am also wanting to connect an IEC port for a floppy drive.
The problem is that I am not sure where to solder Clk and data. The schematic shows TP8 and TP9 (and I have found them on the board) but there does not apear to be anything to solder onto? Due to the white printed lines I can not even follow the tracks very easily.
Please help!?
Thanks

Unfortunately, I am having the same problem. I have tried every combination of connections I could think, and have had no luck whatsoever getting IEC going.

What? no way to connect a floppy to the PAL DTV??? Then it's worthless....!!!!
What says Jeri about that? no help from here (or anybody else?)

Not exactly true. It's simply that no-one has figured it out yet.
I connected IEC, but I get device not present errors.
When I set the bits for the IEC lines, the corresponding line goes low. It may be a kernal issue, not a hardware one.
At least on the Hummer game, the user port is there, and teh client side of dtvload is active, so there may be no need for IEC anyway.

The IEC works fine in the BW (CTRL Press at Startup) mode. I haven't tried any pokes yet, but from what I have studied in the "Programming Info" on the dvthacking page there should be a way to get the colors. Booting this way maybe puts it in PAL video mode? Just a guess but the sheet mentions something about the horizontal scan lines. Also on the schematic, as you pointed out Six, are the user port lines which appear to have a lot of connections to video hardware tweaks within the chip. :-)

I got one load before I soldered everything in, then pfffffft. Nothing in either. SHould have left it unsdoldered lol. HELP!

:-/Hmmm, plenty of signal through all the IEC lines, right up to the plug that goes into the drive. Perhaps when I was testing I hit a 1 instead of an 8 when I went to list. Any rate, Sean seems to be the only one who has a documented successful load from a drive over the IEC lines.

Yeah, I'm still dead in the water with IEC.
No matter what I do, "DEVICE NOT PRESENT" I may have to give up and try to get the user port going instead.

Hi...
I am at a computer exhibition in germany right now. And good news...the IEC is WORKING with the PAL DTV.
We have just tested some PAL demos (Deus ex Machina, Cycle....and all worked fine (with some gfx-bugs sometimes...))
Connecting a floppy and keyboard to the PAL DTV is as easy as connecting to the ntsc DTV...

And maybe someone could tell us exactly where to connect the wires to the PCB?

That's great news, Roland! Any chance you could take some pictures and point out the solderpoints for us? So, a european got it to work, and the americans don't... I'm speaking against my own knowledge here, but I recall some US dude said it did work in bw mode. Could it be a PAL/NTSC issue afterall...? Hi... I am at a computer exhibition in germany right now.

So, here is a picture of the PAL board. It should answer all questions where to connect the lines for keyboard and floppy. IEC Data: the hole below TP9 IEC CLK : the hole below TP8 IEC ATN: the hole right of TP1 IEC GND....get a gnd somewhere..... Keyboard Data: the hole left of TP4 Keyboard CLK: the hole left of TP3 Keyboard 5V and Gnd...again...get it somewhere... (e.g. from the + and - of the batteries/power supply) Ahh, and to test if your keyboard is working: Hold 'CTRL' while pressing Reset (not 'K' like on the ntsc DTV). That brings you right to the basic-mode (...if your keyboard is working correct) And my first impression about the PAL DTV....urgs...UGLY colors...(the ntsc has much nicer colors) ...a very "dirty" white...and the brightness of the colors are totally wrong... (looks like Stevie Wonder has tested the VIC...not the SID ;D) Anyway...I have made a little color-change-routine, that makes the colors much nicer and the games playable (without that, you can't even read the white text on cyan background at summer and wintergames)... ....have to see, where to post this routine....later...

Great Roland, thanks! A shame about the colors though, I wonder why they didn't fix that. Another question, wat about joystickport 2? Are all the solderpoints there this time, unlike on the ntsc where joyport 2 UP is missing?
Some say there are userport lines aswell, but I suspect they are covered by epoxy? Cartridgeport still not present, I guess?

I think you mean Joyport 1.... the Joystick itself is Joyport 2. All solderpoints for joy 1 (dc01) are accessable. Easy to test if you push the joy up, press the a,b,c,d or fire2 (the one on the right side) and read $dc01... A is Fire, B is UP C is Down D is Left Fire2 is Right
