This BASIC interpreter was written and published by DCS and is based upon SP-5025. Once I have more information regarding
the language I will update this page. Interestingly, despite the tape saying there is a converter from B to C on there, it
is actually a converter from David BASIC-C to BASIC-B. It provides a numeric keypad functionality. You must load BASIC-C
first and then load the converter. I have also included two other files I found on random tapes, there is DCS BASIC-B and also
another copy of BASIC-C. The 2nd copy of BASIC-C listed above has some small byte differences between itself and the actual published copy
I have on the cassette shown in the photo so I decided to archive it here.
