Re: Atom-Lite >> CF interface

[Edwin Blink]

Hi Gavin,

just replied to your mail :-) Well not all software work because the 
original Atom swaps the high and low byte and the A-Lite doesn't.
This is no problem when writing and reading back the written data. But when 
reading out read only data like the Identifify Device data the bytes are 
swapped.
The old ATA Device detection  method as used  in BDOS does not work.

These are just minor issues are taken care of in a adapted version of BDOS.

Hi Edwin
I've emailed you directly about getting one of these. Just wondering 
though, why wouldn't all Atom software work? I know the vast majority 
will work, I'm just curious.

Looks like a lovely little bit of hardware.

Lots of wee bits and pieces happening in the SAM scene this year, cool!

Hi  everybody

I'm pleased to see the list so alive lately. I like your game  Calvin ! 
it reminds me of the early 80s handheld games. Simple  gameplay but
very addictive. I hope we will see finished version in the near  feature.

I have some good news too. After a long time I finally have made
a CF interface for SAM that  comes in  a light version of the Atom.
Light meaning it is has 8-bit wide databus. CF-card are accessed
in 8-bit mode.So no capacity is lost and speed  is even faster. It's
designed in such a way that it fits in the right floppydiskdrive bay
whitout the need to open up SAM.
It is also compatible with most existing Atom software (some minor
changes are needed in some cases though) for example I didn't need
to make any changes for the Atom versions of Price of Persia &
Lemmings.

Here are some piccies:
