This simple program- ming method can easily be carried out by referring to the flow chart. Moreover, formulas can be entered as they are normally written. These innovative func- tions are designed with ease of operation in mind. The PC-1211 also serves as an ideal “step- ping stone” to professional computers. Dot matrix display — up to 24 digits with rolling writer [Output display] Characters as well as numerals are displayed with the dot matrix display enabl- ing the operator, in a sense, to com- municate with the unit. The BASIC language can be used to its full potential The display panel makes it possible to display portions of the program (line by line), visual instructions asking for data and showing calculation results. Program capacity 1424 steps - 26 memories with memory safe guard The PC-1211 has a large memory capacity in spite of its slim, compact body. Due to the memory safe guard circuit, informa- tion in memory is maintained even after the power is turned off Programming is by an efficient “one- command, one-step” system. According to your needs, steps can also be used as a memory. (8 steps is equivalent to 1 memory) Reservable key and definable key systems ¢ The reservable key system makes it possi- ble to reserve a key for a function or command which is used frequently. It can easily be recalled by the touch of a key, when putting in a formula either during manual calculation or programming * The definable key system defines 18 programs for each key. Whenever you need a certain program, you can recall and run it with the touch of the proper key Smooth key operation with typewriter key arrangement The PC-1211 employs a key arrangement similar to that of a typewriter. Thus the neat, clean appearing keyboard can be operated easily and quickly. Programs and data can be saved in and loaded from a tape recorder The cassette tape recorder can be used as an external memory device (Cassette interface CE-121 is optional) By saving programs or data on a cassette tape, the information can be loaded whenever necessary. It is also possible to search the saved program data auto- matically by file name or load it for use during the program calculation. Other features * Long-life operation, Auto power-off function. ¢ Playback function enables correction by displaying the formula with a single touch of a key. * Effective tone function is designed to identify the program. (A beep sound can be input during programming.)
