Summary
Speed Comparison of parameteron-based computers and computers built in the late 1950s in Japan using other devices (vacuum tubes or transistors).
The upper part is quoted verbatim from Goto's seminal paper [9] ("The Parametron, a Digital Computing Element Which Utilizes Parametric Oscillation", Proceedings of the IRE, published in 1959). It lists the speed of typical parametron-based computers of that time.
The lower part of the table is created using data taken from a table, Table 2.2 in the report of National Science Museum: "History of First and Second Generation Japanese Computers and the Preservation of (Early) Examples", Akihiko Yamada. (available online at: https://sts.kahaku.go.jp/diversity/document/system/pdf/003.pdf) Lower part is created to mimic the original Goto's table.
The data in the National Science Museum report has obvious typos, and so beware.
