[Coco] Coco Flash

[Salvador Garcia]

Thanks for that info Barry. The table formatting did not come through entirely, so I took the info and created a PDF from it. It can be downloaded here:

And the PDF be put anywhere that is convenient. Salvador

The CoCo SDC and the CoCo Flash do different things.

The CoCo SDC’s primary purpose is to emulate a disk drive. The SDC has flash rom functionality, but it is limited. It can only hold 8 roms at any one time, and all 8 slots are 16k. You can not load more than 8 roms into a CoCo SDC, no matter how small they are, and you can not load roms larger than 16k either. The flash rom banks in the CoCo SDC are intended mainly for loading alternate disk controller rom images, not games, although you can get some game roms to run from there.

The CoCo Flash was designed and built with the intention that almost any rom cartridge can be loaded into it, even games that are larger than 16k that included special rom banking hardware and run in their original unpatched form. It’s disk support though is almost non-existent and is limited to being able to load and run a DriveWire rom image. The two products complement each other.

I hope the formatting on this text table makes it onto the mailing list.
