Source-derived summary

The FX-601P and FX-602P were programmable calculators, manufactured by Casio from 1981. It was the successor model to the Casio FX-502P series and was itself succeeded in 1990 by the Casio FX-603P.

Display

The FX-601P series featured a single line dot matrix display with 11 characters as its main display. An additional 3 digits 7-segment display was used to display exponents as well as program steps when entering or debugging programs. There were 11 status indicators.

Programming

The programming model employed key stroke programming by which each key pressed was recorded and later played back. On record, multiple key presses were merged into a single programming step. Only a few operations needed two bytes. Synthetic programming was possible but not very common.

The FX-601P could store 128 fully merged steps and data could be stored in 11 memory register. The memory of the FX-602P could be partitioned between somewhere from 32 to 512 fully merged steps, and data could be stored in 22 to 88 memory register.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as series of programmable calculators produced by Casio. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 9, 2026. The linked authority identifier is Q5048921. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1981 and 1990.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
