Microsoft Basic 1.0

BASIC 1.0 is the standard <a href="/facts/BASIC/VYMl5TmA">BASIC</a> language for <a href="/facts/Thomson_computers/T9lb4M2x">Thomson computers</a> (<a href="/facts/Thomson_MO5/gAp33jmF">MO5</a>, <a href="/facts/Thomson_TO7/zcKIJ2Uw">TO7</a>, etc.), which is the reference for the entire range. This is an implementation of <a href="/facts/Microsoft_BASIC/SuctFIyc">Microsoft BASIC</a> (BASIC-69).
It was used to introduce children from France to programming in the 1980s (see <a href="/facts/Computing_for_All/kjMUKQTl">Computing for All</a>, a 1985 <a href="/facts/Government_of_France/FTgt9l9r">French government</a> plan to introduce computers to the country's 11 million pupils). Three languages were mainly taught: <a href="/facts/LSE_(programming_language)/fuAHN98V">LSE</a>, BASIC and <a href="/facts/Logo_(programming_language)/Wh4sdwAh">LOGO</a>. School textbooks programs were given in BASIC 1.0 for Thomson and sometimes in ExelBasic for the <a href="/facts/Exelvision/M21sPjgs">Exelvision</a> <a href="/facts/EXL_100/M21sPjgs">EXL 100</a>. 
The first version came with the TO7 computer, released in 1982. On the MO5 (released in 1984 but with smaller ROM), the instruction set is reduced and the double precision is not implemented, so that the interpreter fits in only 12 KB of ROM, instead of 16 KB on the TO7. 
An upgraded version was produced under the name of BASIC 128, for the <a href="/facts/Thomson_TO7%2f70/zcKIJ2Uw">TO7-70</a>, <a href="/facts/Thomson_TO9/zh1G4eV7">TO9</a>, MO5NR and <a href="/facts/Thomson_MO6/9INXccbW">MO6</a>. It included commands for disc operations and other new instructions. 
On the <a href="/facts/Thomson_TO8/cc7jUGdh">TO8/8D</a> and <a href="/facts/Thomson_TO9%252B/Dd004Wjf">TO9+</a>, an even more upgraded version under the name of BASIC 512 was provided.
