Closed Commodore Amiga 500 Rev. 8a with Cover and 0,5MB memory Expansion

[Corum]

Selling my Amiga 500 with motherboard Rev. 8a with Agnus 8375, cover and 0,5MB memory expansion (total 1MB memory), Kickstart 1,3
Without mouse, without power supply

Except for the serial and parallel port, I have tested all connections and they work (keyboard, sound, image output, joystick connection, mouse connection, trapdoor extension, side expansion port, external floppy)

Condition: The keyboard and the side cover of the expansion slot are yellowed, the case is only slightly yellowed.

Price: 220 Euro + shipping

PM me, when interested

It's odd that the extra memory would show up as slow mem and not chip mem. Could I please ask for a close up pic of the Agnus?

Nothing strange here... It's A500 with motherboard from A500+. You have to do some "hardware" modification to map extended memory into chip RAM (at least JP2).

I agree with Tint, matt020, You've confused me now?!? As far as I know, it's always shown as slow ram, until You change the jumpers? Isn't it?

Nope, that is for Rev 5 and 6 boards. This is a Rev 8 board.

However, I do stand corrected, some Google work reveals that the on board chipmem slots must be populated first and then extra ram in the trapdoor appears as chipmem (up to 2mb)
