The Canon S-300 (introduced in March 1987 and also sold as the UTAX T-3300) occupies the same ambiguous “portable-compact” territory as machines like the Brother CE-70. Functionality-wise, it sits at the top of the S-series …

The Canon S-200 (also sold as the UTAX T-3200, below) is a lower-spec model, without an LCD screen, and without any of the extra (Text, Mode, margin and tabulation) keys to the left and right of the main keyboard.

According to specifications the S-300 boasts (this example in my collection is *dead* so I can’t test this):

  • A top speed of 14 cps
  • An impressively low noise reading of 50 dBA
  • A 31 character LCD screen

The “truly compact” AP-1500 (16 cps) is actually less compact (in terms of its footprint) and takes a larger ribbon, however the difference in “class” shows when you compare them side by side …

Weight-wise these two typewriters are similar, however the S-300 shares more in common with the AP-150 (July 1985, 15 cps), and takes the same ribbon. I guess the category it fits into could be “personal compact” as opposed to “office compact”: In other words, a cheaper, brighter, lower-level, more consumer-friendly version of a compact typewriter.

I *think* the Canon MX-300 (below) is the same typewriter …

Model name variants (possibly regional) confuse matters. Another example is this almost identical S-68S …

And this anomalous (I’ve only ever seen this one) Korean-made S-66 MX which is very close to the AP-150 in its keyboard layout …

Different, yes, but note the “vacant lot” immediately to the left of the Return key. The S-300 has the same thing …

The S-300S (S = more storage options?) has “a vacant lot” at the far left of its top-most row of keys. …

Should you find a working model S-300, or similar, let me know how it goes. Ribbon cassettes are still reasonably easy to find worldwide. The typewriters themselves, on the other hand, are becoming increasingly scarce. 😉
