Jupiter 16K RAM

  From the people who brought you the Jupiter Ace comes a 16K RAM expansion. Designed specifically for use with Ace. this pack draws a lot of its styling from the earlier ZX81 RAM packs.
  Slightly larger than a cigarette packet, the RAM pack is finished in a light grey colour and sports the Jupiter logo printed on the front. The construction is solid and the sturdy edge connector should prevent it from suffering from the wobble problems which plagued early ZX81 packs.
  The instructions which come with the pack are brief but concise. Included with them is a short FORTH routine which will enable you to test what size memory your Ace has in order for you to check

whether the unit is working correctly.
  The Jupiter 16K RAM pack costs £39.95 including VAT and further details can be obtained from Jupiter Cantab Ltd. 22 Foxhollow, Bar Hill, Cambridge CB3 8EP or telephone: (0223) 123456.
