Strange A600 behaviour
« on: July 07, 2009, 05:55:11 PM »
My friends: io have issues with one A600.

It has 2.05 rom but i also have 3.1 rom and with both the sympthoms are the same:

- one day , machine works perfect. I have a 1 GB hard disk with Classic WB lite installed. Try to play same random games. Everything is ok.
- next day, nothing, machine wont even boot (black screen) or if it boots, i can get as far as the presentation screen of any game that i was able to play before...

Machine has a 2 MB add on expansion on the pcmcia side. If i took it away, same thing happens

If i try to play some games from floppy, same thing: black screen, machine refuses to boot or i can go as far as presentation screen.

I have tested around 50 games, and it keeps happening randomly...one day machine works perfect, other day machine refuses to work

I have switched Power Supply unit with another ones i have in my collection, also i have tried same games on my other machines, even i tried the HDD on my A4000 and works perfect....its a mystery for me!!!

Mobo is brand new, bought from Vesalia some time ago, latest revision (2B i guess), and it seems to be clean, clear, no visible damage...

Any lights on this please??

Kind Regards

Try cleaning the connectors of all the socketed chips (if any, dunno).

At first glance, It sounds like it could be a bad cap issue or possibly a cold solder issue on the power connector. Take a magnifying glass and inspect the board carefully.
There is a seller from the UK on fleebay that sells the Mobos for under 5 pounds though.
I have Amiga stuff for sale at http://amigalounge.com. You can follow my builds there also.
