An easy way to fill your Apple IIgs with lots of memory.
I had an old RamPro card in my ROM3 GS with only 2 MB of RAM installed on it. Recently I decided to upgrade it to 4 MB but I found that the memory chips for it are no longer easily available. Rather than try to scrounge together expensive old chips from eBay or similar, I decided to go the easy route and buy a brand new RAMGS/4. No hassle, easy availability, and no messing around with installing chips or flipping DIP switches.
Now my GS has more memory than I'm likely to need and I know my memory card is new and reliable. And I bet it generates less heat than the old one (always a concern in a GS packed full of cards).
It is exactly what is useful to examine the operation of RS-232 interconnections. Excellent addition to my tool box . Recommended highly for troubleshooting RS-232 problems since each line is both broken out and switchable in or out. Nice device.
