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.
The RAMS/8 works really well, and replaces the huge Apple RAM expansion board nicely. Everything I've thrown at the board under GS/OS indicates that the board works perfectly.
A little bit more documentation might be nice, though. There's none in the package, and none that I could find on the vendor's website. Only a small mark on the board indicates which way round it should be installed. It might be nice to have some links to RAM tests or other diagnostics too.
