English Amiga Board - View Single Post - Can anyone identify this RAM expansion board??

It is probably a Zydec A500 1.5Mbytes (bringing the total to 2Mbytes)

It is a TrapDoor slow mem RAM card with a gary/68000 board to increase the address lines to more than 512Kbytes.

It plugs into the trap door and you take out either the Gary or the 68000 and plug it into the smaller board and then into the motherboard.

It is a way of adding more than 512Kbytes more RAM via the TrapDoor.

Not a bad buy for £14!
