Re: A3000 - IDE podule

That looks identical (ignoring the extra wires and caps) to the ICS interface that works with ZIDEFS - http://www.zeridajh.org/software/zidefs/snapshots.htm I didn't have a copy of the ROM, I'll give that a try in my IDE interface, it should be compatible. Yes, it looks identical, even including th...

(Ian, if you're not making them any more, I don't suppose you have any spares lying around? :) )
I'm not saying I'll never make any more (I had a small number at the Abug meet), I do still have a few blank PCB's left, so I'll look at getting parts to build them up.

I like it. Just because there haven't been any follow-up post, doesn't mean that people haven't read it before it was edited. Showing that it has been edited shows that it may be different to what was originally read.

Unless your software was specifically written to be backward compatible with the older ICS hardware why would you expect this to do anything useful?

I wonder if the firmware on the 6C version PCB 'catches-up' with these features? Anyone know? Probably, I'm sure it probably gained partition support if nothing else. The 5x version was upgraded quite a lot, from when ZIDEFS was written - the latest version I have is attached. Maybe worth a try? BE...

So I still have no idea where to go from here. A second ICS ideA interface might work but they are so expensive and rarely come up on eBay. Why does it have to be the same interface?

Is it necessary to book this in advance, or can we just rock up on the weekend? I live within walking distance, but I'm somewhat at the mercy of other factors. Depends if you want to bring kit along and have desk space available for you. If you just want to look around, you can just "rock up". AFAIK.

Hi Ian Are you planning on selling the 8-bit boards with the DOM mounting? If so please put me down for one. :) You had one of the original batch, did you get it working? If I sell some more, would people be interested in buying a board with an included DOM (probably 4GB, ony 2GB usable on RO 3.11)?
