CCD module variants

[Raymond Del Tondo]

Hi Gene,

even I don't know all CCD ROM image variants.
However, the CCDR is the image of the original CCD ROM module version B,
my CCDX was the first version where all OS extensions were condensed into a single 4K page.
The version of the CCDX already published features a stripped-down CAT'4 , but includes GETROM/SAVEROM . My later (unpublished) version includes the fully blown CAT'4 functionality and a contrast setting function for halfnuts, but omits GETROM/SAVEROM due to space constraints.

All other versions are derived from either the original CCD ROM or my CCD OS/X, where each derivate has a somewhat different focus, and most were made by Angel;-)
IIRC, Angel's latest version features bank switching.
And he makes very nice documentation files for his images.

Cheers

Ray

1) What's the real differences between these?
2) In the smaller V2 flash image, are all of these really needed? They take up a good bit of space in that earlier flash ram that means some newer stuff won't fit, for example, there is no room for the CCD Example rom that is forthcoming.

Here's what I see in the 41CL flash. What's the differences?

1) CCDR - CCD module 1B (two pages)
2) CCDX - CCD OSX ROM (one page - CCD os extensions?)
3) CCDA - CCD Advanced rom (one page)
4) CCDP - CCD Plus rom (two pages)

What do these do for us? That's six flash pages for these.
