The Casio SF-46xx/47xx/49xx Model Family

Review for SF-46xx/47xx/49xx — The Casio SF-46xx/47xx/49xx Model Family

SF-46xx/47xx/49xx — w/ serial communication port

SF-3xxx - w/o serial communication port

SF-4300 and SF-4600 models, were introduced in the early 1990s

Common characteristics of SF-46xx/47xx/49xx:

  • small but adequate display of 4 lines by 16 characters
  • simple plastic flip-up cover contains no keys or display, only instructions (makes the diary slim)
  • standard Casio 2.5mm serial communications port

SF-4600C/4700C/4900C models have a silver case rather than dark grey.

The SF-4700L/4900L models have a slightly larger display (but same number of characters and lines)

SF-4600, SF-4600B, SF-4600C, SF-4700L, SF-4700C, SF-4600RS, SF-4600Z 64 Kbytes
SF-4900, SF-4900L, SF-4900C, SF-4900RS, SF-4900Z 128Kbytes
SF-4950, SF-4950Z, SF-4950ER, SF-4980, SF-4980Z, SF-4985, SF-4985ER 256 Kbytes

Suffixes on model numbers indicate various differences:

  • "B" indicates a revised and improved model
  • "L" and "C" indicate "Large" versus "Compact" display size
  • "RS", "Z", and "ER" indicate the language/character set (Russian, Czech, or Western European)

The early SF-4300 models were similar to the SF-4600, but with only 32 Kbytes of memory.

Data Types Supported (SF-46xx/47xx/49xx):

  • Telephone (with up to 6 user-defined Free Fields)
  • Memo
  • Schedule
  • Reminder (annual only)

Additional data types supported on the SF-4x50/4x80 models (such as SF-4985ER):

  • ToDo
  • Expense

Other Functions (SF-46xx/47xx/49xx?):

  • Clock with Home Time, World Time, Alarm function
  • Calendar
  • Calculator: standard 5-function with memory
  • Currency/Unit converter
  • Multi-language menus
  • Secret password protection
  • Serial communication: Send/Receive

In most respects these models are fully compatible with the standard range of Casio SF, CSF, and NX digital diary models, but they do not support the Business Card data type of the early high-end SF models, and there are some differences between models in the Expense and ToDo data types.

The earliest models (the SF-4600/4600B) do not have a backlight.

The later models all have a display backlight for use in low light conditions, although it should only be used very briefly since it drains the batteries quickly

Casio has preserved the bad with the good in the user interface of these models. For example, the Insert key inserts one space at a time at the cursor position rather than putting the diary into Insert mode.

There is no way to do a non-case-sensitive search, so for example you have to search for both "Lunch" and "lunch".

The communications protocol is relatively simple and robust, but it's rather slow and not very efficient by modern standards. It does not support a true synch capability, since one side can't synch matching records with the other. If you send duplicate records to the diary from a previous PC backup, it will create multiple copies in the diary rather than being recognized as duplicate.

The PC serial cable used by these models requires a voltage buffer in the cable, making the cable a little more expensive and more difficult to construct for do-it-yourself types.

The recent Sharp YO/ZQ-160/180/190/480 series of electronic organizers are similar in price and capability, but have a simpler and cheaper serial cable (a first for Sharp!).

The Casio SF-5x80/5x90SY/6x00SY/7x00SY Model Family

SF-5x80/5x90SY/6x00SY/7x00SY — B.O.S.S.

Model Memory
SF-5580, SF-5590SY, SF-6500SY 128 KiB
SF-5780, SF-5790SY, SF-6700SY 256 KiB
SF-5980, SF-5990SY, SF-6900SY 512 KiB
SF-7100SY 1 MiB
SF-7200SY 2 MiB

The SF-5x80 models were first introduced in 1996. They were discontinued in 1998.

The SF-5x90SY models were introduced in 1997. They were discontinuted in 1999.

The SF-5x90SY look almost identical to the SF-5x80 models, but have the following differences:

  • Different serial port interface operating at 12 volts instead of 6 volts, and cannot use the same cable as the SF-5x80 models. The difference is distinguished by a 3.5mm plug instead of a 2.5mm plug.
  • New Synch function which allows the diary to synchronize with a PC database. The older Send/Receive function compatible with the SF-5x80 models is still present.

The SF-6x00SY models were introduced in 1999.

The later SF-7x00SY models are identical to SF-6x00SY except for more memory.

The SF-6x00SY models were introduced in 1999. The later SF-7x00SY models are identical except for more memory. Only the SF-7x00SY models are still available. These models are similar to the SF-5x90SY models, including the Synch function and the 12 volt serial interface, but with the following differences:

  • 50% wider screen displaying more horizontal characters
  • Uses AA size batteries instead of AAA size
  • Case design changed to accommodate larger screen and batteries
  • Record size limit increased from 255 characters to 511 characters

Data Types Supported (SF-5x80/5x90SY/6x00SY/7x00SY?):

  • Telephone: 3 separate files
  • Memo: 3 separate files
  • ToDo: 3 separate files
  • Expense: 3 separate files
  • Schedule
  • Reminder (annual only)

Other Functions (SF-5x80/5x90SY/6x00SY/7x00SY?):

  • Clock with Home Time, World Time, Alarm function
  • Calendar
  • Calculator: standard 5-function with memory
  • Currency/Unit converter
  • Games: Poker and Blackjack
  • Multi-language menus (only English, Spanish and French for the SF-5x80/5x90SY models, more choices for the SF-6x00SY/7x00SY models)
  • Secret password protection
  • Serial communication: Send/Receive and Synch
