Title: Twin Cobra schematic / info? Post by: N-e-b-u-l-o-u-s on September 03, 2012, 12:53:22 PM Good day,
Would anyone know where I might source the schematics for Twin Cobra? I recently purchased a 'working' board, but unfortunately it arrived via the post DOA :( (good chance of that happening I guess) At present the game reports RAM, ROM & Sound OK, but then stops with a white 'HW ERROR' message. *** UPDATE : Got the board running, it was just very power hungry and needed feeding! *** Thanks anyway...

Got a related but general question.. On inspecting the board, I found a cluster of 6 "2148" 1024x4bit SRAM chips that a rather warm to the touch. - Not quite finger burning, but a lot hotter than any other chips. Will try an find a source of these online, in case they need replacing - but I guess I should check the surounding logic & voltages as not to blow the new ones. My question is should they be warm at all? I know some memory chips (for example in the zx spectrum) do get very warm under normal operation.

I hunted my usual spots to no avail. I have the manual which was easy to find. Didn't want to start a new thread so dug this one up :) Cheers |
