I have a fully loaded and tested Apple brand 1Mb memory expansion card. It comes in a antistatic bag, but that's it. All you really need to know to use it is that it works best in slot 2 or 4, and that to test it you get into the monitor from BASIC with a "CALL -151" command, followed by a "Cx0AG" command where x is the number of the slot it occupies. This will start the self testing procedure. However, as the title says, it's fully tested as good.
I want $45 for the card, fully loaded. This does not include shipping. I generally dislike ebay, and much prefer to sell to Applefritter folks who will love and use any Apple II gear I sell. My prices are darn fair, but I've recently sold to a couple of active users here who were very happy with their purchases, and that's what really makes me happy. For contrast someone is selling a minimally loaded card like this for $75 on Ebay currently. I do have the original box for this item but would want an additional $10 for that, as that sort of thing seems to be a greater premium accessory to some. You can find the manual that goes with this in PDF format online.
