I trimmed down UCDOS 7.0 and made a slim edition. After compressing it with CABARC, it's only a little over 160K left (quite a bit smaller than the Tianhui pocket edition too!), download here:

Hehe... not very good....

Then what would count as really good?

Pretty good. If you could add compact input methods like Tianhui's "Wubi" and "Pinyin", it would be even better ^_^

Too bad the size of UCDOS's input methods seems quite a bit larger than TW's! Teacher Mo might as well try hooking one up.

Why can't I use it? Can someone help me?

All phrase groups have been removed. Although that may feel a bit unpleasant, after compression the two input methods are only a bit over 70K

Actually, you can also use PY.COM and PY.OVR from UCDOS version 3.0 (note: in the archive, PY.com is named PYY.com, because I already added drive-letter detection, otherwise it could only be used in the C:\UCDOS directory!)

If someone modifies PY.COM, it would even be possible to combine PY.COM and PY.OVR into one, and then the executable could be run after compression! The runtime size would also be even smaller!!

Actually, the length of UCDOS's .IMD files is related to the encoding code length and the number of characters and phrases. To shorten py.imd, you need to (1) remove phrase groups, (2) shorten the code length. Of course, the encoding also needs to be optimized. For example: cover only single characters (code length reduced from 12 to 6), simplify and optimize the encoding by using u/i/o/m to represent zh/ch/sh/ng respectively (code length reduced from 6 to 4), or even merge it with WB! (UCDOS7.0's PYWB.IMD(115K,.RAR 69K): no need to switch between PY and WB anymore, just type freely! URL: http://www.cn-dos.net/forum/viewthread.php?tid=17019&fpage=1)
