It was, but very limited. The UK model had 1 kB of RAM, no sound, no
graphics, no colour, 32*20 text, and a limited 8 kB ROM BASIC. Expansion at
the time was limited to a tiny cash-register-style printer and a 16 kB RAM
expansion, and that was it.
The Spectrum had 48 kB RAM, a slightly more flexible 16 kB BASIC with
graphics and sound commands, 256*192 graphics in 16 colours (kinda), and
could drive disk drives, printers, joysticks, modems, whatever you could
For me, more interested in programming than games, it was better than a C64
-- the 64 was expensive in the UK, its disk drive slow and also expensive,
and its BASIC was rubbish. Better keyboard, though, and yes, much better
sound and graphics.
The big limitation of the Spectrum was the piezo beeper sound and the
limited graphics. The TS2068 fixed both: it added a AY-3-8910 sound chip, 2
more screen modes (512*192 and 256*192 with 32*192 colour resolution
instead of the Spectrum's 32*22) -- and the ROM could be paged out to run
It's a tragedy that Sinclar never adopted those enhancements for the
Spectrum 128... or that Amstrad didn't merge the Spectrum and CPC lines
when it bought the Sinclair product line.

But I'm told the Spectrum never made a profit for Sinclair Research,
whereas the ZX81 was very lucrative for them.
