Toshiba SPARC LT -- first RISC laptops from 1990. The AS1000 were a range of portable SPARC computers marketed in Japan from ¥1,980,000.

"Some experts have questioned the need for laptop workstations because the scientists and engineers ... are often networked into high-powered mainframes. [T]he advantages of portability are not as clear-cut as they would be for personal computer users"

Early L10 had i386-performance while SuperSPARC+ C70 were in PowerPC 601 territory.

Introducing the Sony NEWS 3250 Unix Laptop, Sony advertisement 1991.

Apparently, Sony also produced RISC laptops, based in its NeWS range of MIPS-powered Unix workstations. Shipped in 1991, the NEWS 3250 was apparently the second RISC portable released in the early 1990s.

Based on a MIPS R3000 @ 20 MHz, the NEWS 3250 ran Unix SVR4, on a monochrome LCD with "increditle 1120 × 780 resolution".

@OpenPA WHAT

@OpenPA - wow - that kind of resolution was totally unachievable for a student carefully speccing his PC, even using a generic CRT display, at that time. 800x600 was tops, unless you went interlaced...
