Hello people.
I got a 386sx 16mhz (mb Headland H-18 2.0 with 4 mb 30pins modules) kit a few mounths ago. The seller had photos with it working. But I didnt had time to install it when arrived. I just checked if there are the actual parts, not some bricks, and left alone on a shelf. I bought from this seller other times and never had any problems.
Now, after almost 2 mounths, I decided to install it in a case.
But it is not working anymore. I have only 2 isa video cards and I only get these garbled screens with both of them. No beeps in the pc speaker and garbled graphics.
I tried with 2 different PSUs: one original AT from a working 486 system and other ATX with AT adapter, with the same result. No beeps in the pc speaker and garbled graphics.
I have resitted the 4 x 1mb memory modules. I tried pairing just 2 by 2 and is the same result. I cant test the memory modules in other system, because I dont have any with 30pins memory slots.
I tried the 2 isa video cards in my other 486 pc and they work just fine.
Did anyone experienced this weird and strange screens? And what could be the problem?
