Tadpole Technology was a small British computer company formed in 1983 and originally based out of Cambridge, who amongst other things manufactured VMEbus boards for industrial applications, along with military spec, small server and laptop computers. During the 1990s and perhaps most famously, Tadpole produced a range of high-end laptops that were based on the SPARC, PowerPC and Alpha RISC architectures, running Solaris, AIX and OpenVMS respectively.
A previous series of articles followed the restoration of a SPARCstation IPX, noting how Sun UNIX workstations were a much-coveted object of geek desire in the early 1990s. However, Tadpole laptops which boasted a RISC processor were a great deal rarer than such workstations, with an almost legendary status and you were lucky if you even got to see one in the flesh.
In this series of posts, we’ll take a look at restoring a third-generation Tadpole SPARCbook, which was introduced in 1994 at a starting cost of $10,950 — which with inflation would make the price tag equivalent to almost $20,000 or £15,000 in today’s money!
SPARC hardware in general has a special place in my heart, but the Tadpole SPARC laptops are in a whole league of their own – mythical beasts I know exist, but which are incredibly rare, and even more stupidly expensive when they come up for sale than even regular SPARC hardware.
I’d not give up my firstborn for one, but we can talk about a kidney. Or two.
