Hello,
i have a grundig tv set (29304) (schematic url is at the end) with an east-west-problem (i dont know if this is the technical name - at least in german it is known under this name) - this means the picture is smaller in the middle, than on the top or bottom.
It looks )_( instead of [_]...
Thank you very much!!!

A resistor, which is in the focus-path was defect (but not overloaded)...
thx

Hi!
I have got a defect notebook (want work at all... dosent react on any (power-)key). On the mainboard i have found 4 SMD-ICs grouped together, 2 of them a visually defect (overloaded). I have attached a picture of them.
I wasnt able, sofar, to find out the use of them nor the IC-company who...

Yepp, thx for the comment... Meanwhile ive found something looking really impressive: https://openwrt.org/
it works with the linksys products and some Asusrouter. I think, ill put my hands on some of those...

pic 18.432mhz circuit layout
For those who need some additional help according to the baud-matching-problem (if it is even one) ive designed a little xls-tool.
Just set the xtal-fq and you get the matching (+/- 3%, acc. to the datasheet) baudrates.
Ive attached it - if someone needs it, its...
ds89c450 programmer
I have some pics of my first running DS89C450 attached. It is a 8-Bit MCU@24Mhz driven blinking Led :). how usefull!
So, now i can study the mc51 architekture a bit... iam normally used to the AVR (Atmel's 8bit riscs) - But ive heard a bit of 8051 at my previous school...
ds89c450 uart timer tmod
Yep... thx for your post... ive read the errata already before... in my case (now i use a 24Mhz xtal) the maxBaud (acc. to this formula) would be ~20kbaud. But the matching to one of the timer-reloads was the problem. I dont know, why they had used only a few possible...
ds89c450 user guide
Wuha! Gotcha!!
Thank you - it works!
I never thought, that ther may be a problem with Bauds> 9600. Iam used to AT AVRs and ther i never had matching-probs with bauds up to 115200 at 8Mhz.
But again: thx!!

89c450 clock configuration
Hi!
> I've just got two '450's myself
Two? Samples i guess?!? Ive also get them as samples. :-)
Thx for the hint - i often forget to check these things, but not this time... Ive used differnt terminalprograms on different computers with different platforms (telnet...
ds89c450
Hi!
Does anybody ever tried somthing with a DS89C4[3/4/5]0 Microcontroller? Ive 2 of them and tried to communicate with the ROM-Loader (which should be onchip) - but without success.
Ive set it up on a problem-board, with a xtal (12mhz) and pulled the rst high, the /EA and /PSEN low...
ipaq service manual
Does anybody have something like a Servicemanual for HP's iPaq?
Especially i need some infos of the accu-to-ipaq connection of iPaqs with internal Accu (like 3970).
Or a Pinout of the external Connectors of an iPaq would be also very fine!
Thx, Daniel
