	To upgrade a laserwrite LS from 512k to 1meg, simply plug into the 
spare DIP sockets 2x 44256 memory chips. these chips are the run of the mill
256k x4 bits memories.

Once installed in their sockets, move the memory jumper select from .5M to 1M.


and this would have upgraded the laserwriter to 1 meg... quite cheap actually.

but make sure;
the power is off
you are using anti-static procedures
the chips are installed with all pins into their respective sockets
and their orientation is correct (notch to notch)


you can fin these chips from virtually any electronic computer shop.
they are used in the mac classic memory board, IBM vga cards etc..
