768 kB RAM expansion - expands the A1000 to 512 kB Chip RAM and 512 kB ranger RAM (slow Fast RAM)
24 64k×4, 120 ns DIPs
supplied with a special Kickstart disk (Kickstart 1.2+) which enables the additional 512 kB
the additional 512 kB can be disabled at any soft reset by pressing the left mouse button
connects to the front panel expansion slot
the A1000 front slot lacks the required amount of signals for addressing 768 kB so 12 wires and four ICs have to be soldered into the A1000
made of two circuit boards like a sandwich - does not fit under the original front slot cover
the supplied replacement face plate protrudes 1.5 cm to the front and also a bit downward so the keyboard cannot be pushed under the Amiga - raising the A1000 a bit helps
