Useful. title url text The Pocket Computer Museum http://pocket.free.fr/ The site to visit for pockets computers ! author date text Bruno Chatard (Switzerland) Tuesday 12th April 2022 The blue F key of the FX-700 presses a switch on the keyboard which was also present on the PB-100. It had become common among students to drill the PB-100 of the time to add this handcrafted F key and thus inherit the accelerated entry of the mathematical functions (SIN, COS, etc.). author date text Carl Holmberg (USA) Friday 21st January 2022 As Ivan says, the interior of the MK-85 has nothing in common with the Casio, using the KA1013VM1 processor, one of a family that grew out of the original DEC LSI-11 cpu clone. The PDP roots ran deep: it can be programmed in the DEC assembly language MACRO-11. Using an N-Queens benchmark, BASIC 10m45s, fast mode BASIC 2m, assembly 1.22s, fast mode assembly 0.22s. author date text Ivan Mikhailov Thursday 13rd August 2015 Two corrections:\ 1. In Russian, MK stands for "microcomputer".\ 2. MK-85 has the body cloned from Casio but it''s absolutely different inside. MK-85 is 16-bit and it''s compatible (to a degree) with DEC PDP boxes. E.g. one of its variations was used for strong cryptography (to wire money transfers via unsafe public networks). Original design of MK-85 (with misleading name MK-87) has nothing common with Casio: http://www.computerra.ru/upload/apismenny/elektronika-mk-87-1.jpg author date text Joe Jack Johnson (So-Cal.) Saturday 14th February 2015 This was cloned down to the buttons by the Soviets as the Elektronika MK-85....probably had different guts (the Soviets had round microchips for calculators for some reason.) "MK" stands for "mark." Elektronika was a stock name for electronic gadgets made in the USSR that weren''t radios. /museum/casio-fx-702p /museum/casio-pb-100 /museum/casio-pb-300 1002 url date https://web.archive.org/web/20230605032402/http://www.old-computers.com/museum/computer.asp?c=1002 2023-06-05

The FX-700P is quite the same machine as the PB-100, but is a member of the more scientifically oriented FX product family. Consequentially, it is called "Programmable Calculator", as most FX family members.

It has 2 KB RAM, i.e. it was equipped with two HD61914 RAM chip instead of one like the PB-100, but no further RAM expansion was ever made available.
Moreover, the mathematical functions (SIN, COS, etc.) were assigned to the keyboard, by means of an additional function key. Apart from that, the hardware of the two machines is identical.
