BOOK-KEEPER was written in ’92 by O.P.A. and uses the RAMBO program space to store the large amount of ‘accounting data’ that is now possible to sort, usage, and edit because of larger amount of memory space, and it also support 80-colunm text for much better viewing of your ‘general ledger’.
The program was never officially released commercially, but recently thanks in part of some ex-OPA employees saving TI99 stuff for no reason, we been able to recover most of this wonderful program, and plan to make it one of our ‘public’ releases later on during year 2023 as part of re-birthing fun!
