CompuKit EconoRAM VII 24K fully tested S100 IMSAI Altair:
The EconoRAM VII 24K was an extremely popular RAM card because of its versatility. The board consists of two 4K blocks and two 8K blocks. Each block can be placed on any address block allowing you to fill in the holes in your memory system.
I have a very exhaustive memory test that includes sliding 1's, sliding 0's and full 8-bit range testing. I have included a printout of the testing output. This board passes every test on every address. I ran the testing system for 24 hours.
Almost all S100 cards sold on are sold as 'untested'. Not this one.
