    HM62256LP-10, i cant find any proper data sheets regarding this memory SRAM chip, i need to know the size of it :S

    Also i think the forum should contain a new area where people can ask for part identification :)

    Many thanks
    Robin

    Why do you put wiring on the bottom?

    i put mine on the top and let the wire go through the hole to the bottom, that way the underside is neat and easy to see connection problems

    So it was not for a bird to have her nest there:p. Ok bad joke could not resist it:rolleyes: But back to topic. I also prefer using the "top layer" for wires then working with vero board. Also using different colors for say power, data and address,control buss and so on. It can tide things up

    I don't understand your bad joke.

    OK, i was using wire at bottom because at top i don't like it...
    In past i have solder on both sides many times

    It ends up llooking like a birds nest. I know. Hence my joke about RRITESH KAKKAR photo. I am glad I do not have to look for error in that design

    the only time i (now) do wiring underneath is if i use magnetic wire (like vero pens). They are surrounded by insulation by when heated it turns into flux, very useful :D
