Re: ICE T65/Z80/6809

Was wondering the max lenght of a flatcable from the level shifters to the 6502 socket. Would one foot (30cm) be too abitious ? I don't think there is a single answer to this, as so much will depend on how the target system is designed. For example, a 1MHz Atom will probably have more timing margin...

Re: ICE T65/Z80/6809

Have you connected it to a target system yet with your level shifters? An Atom is ideal to start with, because it doesn't have regular timer interrupts. These really mess up the utility of single stepping on the Beeb, as you always end up in the interrupt handler. I don't yet have a good answer to t...

Maybe these changed,...

Most likely you have loaded the wrong build of MMFS for your system.

Hi Jon, Actually, I see from this thread that you have already successfully built one of these, so you can ignore most of my thoughts above about using a different board and using Verilog.

Re: Graphics on the Multicomp

Jon, Is this the CP/M machine you are talking about? http://searle.hostei.com/grant/Multicomp/cpm/fpgaCPM.html The main concern you have is RAM - CP/M seems to need 64KB minimum. The EP2C5 FPGA has 26 M4K RAM blocks, which amounts to 13KB. So I don't think it's going to be possible on that board usi...

Is there any reason it shouldn't work on the Matchbox and/or PiTubeDirect? I remember there was some discussion a few weeks ago about changing some of the 6809 Tube Client ROM APIs. I don't remember what the outcome was.
