it's been while since the last time i used this old Mac. A few days ago i tried to power it on to take some pictures and surprised to see my screen like this and startup sound distorted:



Do you think its a problem with the logic board or memory upgrade board or the crt monitor(analog board)?

more pictures can seen at http://www.flickr.com/photos/91379880@N00/sets/72157623523929099/with/6242620937/

i posted about this mac here before at viewtopic.php?f=7&t=13137&hilit=giolicious

It's actually an original Macintosh with RAM upgrade.

Here's the Mac board without the RAM upgrade:



and here's the memory board:



One more thing, do you think i can get the two 74LS244 chips from the memory upgrade board and placed it on the Mac logic board?

Anyone knows where i can buy cheap 128k or 512k macintosh board to replace those missing chips?

will highly appreciate any replies and suggestions.
