   1 So,  instead   of   threatening   softwarehouses, I dare people to contact  them  onan open basis and  just  ask  them.  Sure,it's getting exceedingly difficult to finda  contact  address  for  each   copyrightholder since most of said software  houseshave folded in the mean time, but  there'sno reason to stop. So many ways have  beenleft unused.  We  should  join  forces  totrack them down and ask.                                                            Are people simply too frightened  to  talkto the copyright holders and is  all  thisstirring up just  a  smokescreen  to  hidebehind? I should hope not!

This is a vital  piece  of  home  computermythology,   symbolising   the   legendaryprice-cuts that reward the patient. It  isalso a severe lesson in bad marketing.  AsCommodore chronicler Mike Tomczyk says  ofTI in his book 'The Home  Computer  Wars',"I figured that if a giant  semi-conductorcompany that made its  own  chips  chargedthat much money, they either  didn't  knowhow to control their  manufacturing  costsor were gouging profits at the  consumer'sexpense."

There  areall the usual ports at  the  rear  of  themachine, RS232, Centronics printer, and anon/off switch (hoorah!), but interestinglyfor this class of computer, there's also amodulator socket for plugging  into  a  TVset. Clean and simple lines,  but  a  verypowerful machine. Alright  let's  whip  itapart.

Although this  willmean something to converted PC  users,  itmeans  nothing  to  the   likes   of   me.Apparently all this  yibbling  means  thatCGA is the most popular graphics  standardused by PC types. It's a 40  column  *  25line or 80 column * 2
   1 " * 1".  The  casenow became silver/grey,  and  contained  ahinged door at the right top  which  wouldbe  used  for  cartridge  based  software.(More about this  later.)  The  keys  werereplaced by a full size keyboard  with  42solid plastic, soft touch keys,  includinga full size space bar.  (One  drawback  tothis keyboard is that the space bar  seemsto be "dead" on the ends, and must be  hitclose  to  the  centre.)  The  sides   nowcontained Atari standard  joystick  ports,which are supported by a new STICK commandin BASIC. The final noticeable  change  isthe addition of an on/off  switch  on  theleft side of the computer.                                                          At first, Timex had planned  on  marketingtwo different versions - the 16K T/S  2016($149.95), and the 48K T/S 2048 ($199.95).Sound familiar? In the end, however,  onlythe 48K model  was  released,  dubbed  theTimex/Sinclair 2068. Actually,  it  is  inreality a 72K unit, containing a  24K  ROM(16K + 8K  bank  switched  to  handle

As an example, consider the humbleSpectrum. The ZX81 had  been  a  wonderfulsuccess and the early Spectrum  seemed  tobe continuing the trend. The Spectrum+ waslaunched with  a  better  keyboard  and  areset switch and  everyone  seemed  happy.Then came the 128. This was amajor upgradeyet it retained many of the old  problems.I  personally  liked   the   machine   andrevelled in the new BASIC editor and soundchip  yet  it  could  have  been  so  muchbetter. The Spectrum could use microdrivesso why not build them into it. The QL case(or a version of it) could have housed thedrives and Interface One could surely havebeen put on to the same motherboard.

The  Spectrum  couldmake sounds, had  more  memory  and  coulddraw graphics  in  COLOUR!!

Therefore,we've got to  execute  it,  otherwise  theloading system may crash. Then it  resumesloading at #5B35 with the POKEs firmly  inplace.

AB5F,B6 isthe POKE for infinite lives (which can  beworked out by a forwards  or  a  backwardstrace), and JP #F5BC jumps to the game.
