In 1976, there were only two practical forms of RAM memory whose price per byte was within an order of magnitude of each other. From what I understand, a RAM built out of bipolar chips could offer better performance than a MOS-based RAM, but I think a 64-bit bipolar RAM cost as much as a 1024-bit static RAM. | |
