Arek's TF534 build

Post by arkadiusz.makarenko »

My first build. It took me 6h.
Tomorrow I am planning to program it, and hopefully start Diagrom.
Forgot to other 0.1 uF caps.
There is no way that someone could build it without microscope and half decent flux.

Hi,
CPU with that mask will probably not work @50Mhz, it will run stable @40Mhz though

I have installed 40Mhz crystal here.

Thank you for PCB by the way.

You are welcome! glad it arrived safely, was worried it will be lost without tracking..

40Mhz should work nice. Please remember Systest will crap out once MMULib is installed, so scan ram with Systest started from ADF or on a system without MMULibs

I think I killed one of the chips during soldering. Question is which one.

First thing I would check is a short to ground on the 5V rail, check for continuity across the PWR pins.

I get OL one way and something around 120ohm when measured other way round.

found first issue - I had crystal installed upside down. :/
