Neil are you sure you have the windows on the z80 board set correctly. From the monitor flip 64k+ into RAM at 0H and check it out by substituting bytes, then flip it back and forth with 0H RAM and check all ok. John Sent from my iPad I was trying to run BASIC with no luck. As the system boots and some of the smaller programs run (PIP as an example) I know the core system is running. It may be too small a TPA causing BASIC to hang.
-- I haven't been able to get banked mode CPM to boot; I'm still trying to isolate the issue; items I need to look at: * Jumper setting on my 4Meg SRAM card. * Test the RAM on the 4Meg SRAM card. When banked mode CPM stops loading the system is left looping between addresses 0x010021 to 0x010091; there is most likely a hint in this. -Neil You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
