[Coco] Coco 1 vs Coco 2 software compatibility

[Bill Pierce]

There's a difference in the bitbanger. That's the reason there's Coco1 and Coco2 versions of HDBDOS and NitrOS9 with Drivewire. Due to differences in the chip, the Coco 1 can't do the baud rates that the Coco2 can.
I'm not sure what the exact differences are, but others will probably elaborate.
Also, earlier models of the Coco 1 didn't handle the 64k upgrade well. I think the "F" board (the last Coco 1?) was the first Coco 1 "officially" setup for the 64k upgrade (I may be wrong on this one).

Subject: [Coco] Coco 1 vs Coco 2 software compatibility

Hello everyone,Does anyone know of any _significant_ software incompatibilities between a64K (Disk) Extended Color Basic Coco 1 and a 64K (Disk) Extended ColorBasic Coco 2?  Not looking for anything related to OS9/NitrOS9.  The onlything I can think of is perhaps any software written to take advantage ofthe "T1" based video chip in some Coco 2's for lowercase.  I do realizethere are many hardware differences, but focused on software for now.Thanks!-Ron-- Coco mailing listCoco at maltedmedia.comhttps://pairlist5.pair.net/mailman/listinfo/coco
