One of the enhancements in the iMDX-511 was a fast
block write to the crt.
I'd bet that write to arbitrary IOC memory has something to do with that.
No, that's command 0x0f which is documented, and can only write to
screen memory.
I made two or three RPC86 boards from SBC-86/12
boards. It wasn't very
easy.
That was something I was hoping to do also, if I can't obtain an RPB
or RPC, but can obtain an 86/12A, 86/14, or 86/30. It's encouraging
that you've confirmed that it's possible, but discouraging that it
sounds like a lot of work.
I sent out your Single Density ISIS-II 4.3 boot
diskette today with Kermit
Thanks!!!
