The FX-9000P had a 5.5'' video display and a complete keyboard with calculator style keys. The unit also had four slots for plug-in RAM or ROM modules. The basic model came with 4 KB of RAM. Two RAM modules were available: 16 KB N-MOS RAM which didn't retain information when removed, and 4 KB C-MOS RAM with back-up batteries that stored the information outside the system for three years. The CA-BASIC interpreter, located in a 12 KB ROM pack, was very close to the FX-702P pocket calculator one, allowing RAM memory to be shared into 9 separate areas (P0-P9). An optional Extended BASIC was also available. An interface unit was available that plugged into the main housing and provide RS232S and printer interfaces, as well as floppy disc capability (2 x 160 KB). More info and better pictures needed! **Rui M. Dos Santos** experience from Angola:\ Around 1981, we ordered and received one CASIO FX9000P for tests and trial.\ This machine arrived at same time the ZX80 and the NEW BRAIN for checking the technology and how things work on PC´s. We used the FX9000P for tests and the machine was very nice for home and mathematical use but not for any serious commercial application as no CP/M was available. The way CASIO built the unit in modular mode, was, though very smart... One printer interface was available, one FDD interface was available... We could use the basic machine of add later the interfaces and the printers and FDD´s. The other nice part on this machine was the memory... It was in plug in cards which kept the all data on them. This way we could store data and programs in multiple cards and use them according to the application. Basic small test applications were made, mainly one full "working clock" with one analogue look.
