The PACE TR-48 was a fully transistorized general-purpose analog computer developed by Electronic Associates in 1961. The TR-48 was marketed as a desktop analog computer, and was aimed to fill the gap between the smaller and popular TR-10 and the larger 231R system[1]. The unit originally sold for $25,000[1]. At the time, the TR-48 was considered the best general purpose analog computer on the market.
