| Feb 1, 2004 | After fixing a bug in the ABX instruction, System09 now runs FLEX9 in a RAM disk, using the DAT to map the top 192K RAM into a Track buffer at $9000. Flex9, and RAM Disk images are now available. | |
| Jan 25, 2004 | After burning the midnight oil, and then some, I have debugged System09 sufficiently to be able to run TSC's XBASIC under the FLEX9 Operating System. The transfer address for FLEX9 is $CD00. The Transfer address for XBASIC is $0000. Copyrights for TSC's software have expired according to the Flex Users Group. | |
