Memotech explores the excellence of your ZX81

Memotech, the company which would end up producing its own range of well-regarded almost-MSX machines during 1984, started out as a producer of memory and interface expansions for Sinclair's plastic-wedge ZX81 computer - a computer somewhat optimistically endowed with "excellence" by the advert, but which was a very successful machine, selling over 1.5 million units. 

Sinclair's own memory expansion packs were famous for requiring blu-tack to keep them in place, but Memotech's were designed to be "wobble free". 

The 64K pack (referred to in that annoying way that loads of adverts in the 80s did as a "pak") retailed for £68.70 plus VAT, or about [[79|1982]] in [[now]] money.

Memotech already had a US presence, with an office in Denver, Colorado. Unusually, Memotech's Memopak 64K was retailing in the US for roughly the same price, allowing for exchange rate, rather than the usual situtation where the UK price would simply be the Dollar price with a £ stuck to the front.
