On File
On File Database Management System was released in June 2024 by KSL in order to celebrate the anniversaries of CPC (40 years!) and CP/M-80 (50 years!).
As per COSMOS, On File has been developed on the basis of the hardware peripherals as well as the software that were (contemporary) available for the CP/M and the CPC6128: the 512 KB Dobbertin Memory Expansion, the ParaDOS or X-DDOS ROMS for the external (800 KB) floppy drive, the 20 MB Dobbertin Harddisc, the Amstrad Serial Interface, the Amstrad Parallel Printer Port, the CTM640/CTM644 colour monitor, the AMX Mouse, the MicroScript (142 KB), the WordStar (706 KB), the Protext (406 KB), the Multiplan (208 KB), the SuperCalc 2 (240 KB), the DBase II (272 KB), the DR Draw (235 KB), the DR Graph (306 KB), the MAXAM (206 KB), the Atlast Plus (224 KB) and other Programming software. On File includes its own graphics routines (similar to GSX), is based on the Dobbertin version of CP/M 2.2 (v1.2) which provides 59 KB TPA, supports the RAM expansion and the 20 MB hard disk.
