JMS was originally written by a Somerset Programmer, Dave Turner, who in 1983 had been approached by a joiner wanting software that could produce estimates and cutting lists for bespoke joinery (windows, sliding sash and doors). Nothing else was available at that time, and Dave produced the software to the joiner’s specification. The joiner ran this software for nearly 20 years in his workshop and LOVED IT. The software was originally written for the BBC micro computer and then written under Microsoft DOS. No graphics were included at this time, but the programme was still very powerful.
