Sharp EL-5510/PC-1421 manual or reference

[robve]

I have one NIB with the English manual and like it a lot!

The PC-1421 is essentially a PC-1401 with all of the PC-1401 S-BASIC features. It has financial keys and BASIC functions built-in without compromising the PC-1401. The PC-1421 TVM and CF functions are included in BASIC. Quite impressive that they managed to squeeze this into the ROM.

I noticed that the TVM and CF keys and functions are identical to the EL-733 calculator's key presses. So for key operation the EL-733 manual can help (the EL-733 manual is quite good with lots of examples from simple to advanced). The keys and key layout is intuitive and should be easy to understand, if you've used financial calculators before.

There is a German PC-1421 user manual on the web, but no English version. PockEmul does not include an English manual either. Remy always includes the latest manual scans so I doubt there is an English version PDF on the web.
