Ach! - Stereotypical German ejaculation. Sets the scene. Preshadows the use of Acht later. The writer is a stereotypical German with bad English (i.e. one that does not exist).
"It a short weill until the other acht prepared are will take"
Okay, lets unpack this first clause. It's using stereotypical German word order with the verbs at the end.
It (will take) a short weill until the other acht (are) prepared.
'weill' is mis-spelled, and should be 'while', but Weill is the family name of a well-known German composer, whose first name was 'Kurt', which is a near homonym for the German word for 'short' - kurtz This comes from the Latin curtus, which means 'shortened' or 'short', and the the etymological root of the English curt, curtail, and curtation. Acht is the German for 'eight', one less than nine, which is confused by English speaker with the German negative, i.e. the german Nein is heard as the English 'nine' (9). So by saying you do not want any computers, this is misunderstood as wanting 9 of them.
Second clause: It's using stereotypical German word order with the verb at the end.
"and they more than dry pennies cost will"
'dry pennies' - confusing the German word for 3 with the English word 'dry'. Kurt Weill wrote the music for Bertold Brecht's play, The Threepenny Opera ( Die Dreigroschenoper ). So they are not cheap computers.
Last sentence
"The supplier will not makie messer of it."
The verb is in English order to preserve the pun 'makie messer of it' - 'make a mess of it'. That is, the supplier of the computers will do a good job. But probably the most famous music from the play is "Die Moritat von Mackie Messer" - or in English "The Ballad of Mack the Knife", or simply "Mack the knife".
So it is all an involved selection of bad puns riffing on the German-ness of the computer and the play The Threepenny Opera by Bertolt Brecht with music by Kurt Weill.
