	It has a low performance CPU, with an average video controller for a 486. The CPU does not release too much heat so active cooling is not necessary. The keyboard has reasonable tactile feedback but it is far from being the best, with quite a long key travel and a mushy feel. The Ballpoint cursor system (if you have the rare side mouse attachment available) should be alright. The laptop's plastic case is quite durable but the internal design is horrendously complex, requiring lots of disassembly to access even the harddrive.

	The ~~FDD~~ drive was a very poor choice, since the belt driven disk rotation fails after many years, compatible belts being harder to find unreliable. The removable disk bay is very good for a laptop of its generation and the rechargeable battery can be easily removed or replaced. There were many Toshiba laptops that used the same battery and working with a removed battery does not affect stability or aesthetics. There are two more internal rechargeable NimH batteries inside the laptop that may leak and are somewhat harder to replace (not the typical, compact CR2032 3V button cell). They are used for Bios settings and memory suspension features.

	The integrated speaker is quite good, although capable of only the standard PC beeper output. No effort was made for integrating a sound card, not entirely unsurprising for a laptop released in 1994, but quite so for a Japanese laptop.

	The standard ~~HDDs~~ supplied by Toshiba have a known tendency to have their heads stick to the parking position limiter when old, making the drive fail to start. Careful internal disassembly is required to unstick the heads from the parking position. Use care and touch only the drive arm near the center pin to slowly unstick it. Overall, the hard-drive offers medium performance while having quite a pleasant sound in operation.

	Software support is great in DOS and Windows 3.1. The video controller has insufficient acceleration and low screen scrolling performance and the CPU is quite slow meaning that even running in 640x480 is quite taxing for the machine. The CPU is by far the slowest component.		Software support is great in DOS and Windows 3.1.

	Disassembly is very difficult as there are many screws, layered boards and a complex way to link components. This is typical of many compact Toshiba laptops. Unfortunately, the poor board design and many shortcomings such as the harddrive make this model quite avoidable. Keep in mind that compatible 486-era harddrives are very difficult to find in good condition and they are quite small. Modern IDE harddrives and flash storage solutions such as compact flash are entirely incompatible.
