[Coco] Drivewire with RS232 pak

[Bill Pierce]

The Coco3 will do 230k on the bitbanger "as is". There is actually a version of HDBDOS on SourceForge that uses this and works well, but the NitrOS9 drivers need some tweaking to be made to work properly.
Unless they've been changed, the HDBDOS & NitrOS9 versions that are for the "Turbo" mode are labeled as "dw4" where as the normal versions are labeled as "dw" or "dw3", which is kind of deceptive naming, though turbo will only work on later versions of DW4.

Gene,You mentioned something about DW being able to run at 200+ kbaud on the bitbanger with a new opamp? Got any more info on this? That is - what new opamp, where does it go (I presume somewhere inside the CoCo), etc?Andrew L.
