Not a > huge problem, but I am curious as to why it won't work in a IIgs. Will take a wild stab and say probably the Z-Card flavour of CP/M doesn't take care of/turn off the 65816 interrupts before it switches to Z80 mode. Red
I'm using Softcard CP/M. I don't have the version of CP/M that came with the Z-Card. Of course, this doesn't mean that the Softcard CP/M disables the interrupts either. Since the Softcard board I have doesn't work, I can't test this. I'm going to dig up a handfull of TTL chips and see if I can get the Softcard board working. ... Which ALS card do you have? The Z-Engine (generic softcard clone) or the "CP/M Card": http://mylinuxisp.com/~jdbaker/oldsite/images/CPMcard.jpg which needs CP/M 3.0? Red
