By “stock”, I assume you mean the version we forwarded to the online repository (hopefully you don’t mean 3.3.0’s grfdrv - it’s slower and more buggy than the current EOU release). As an aside, all the drivers source code is included on the hard drive image for EOU - we actually make EOU from EOU (sometimes on real hardware - and mandatory for testing, and also in emulators where we can overclock to assemble large projects quickly without ever having to exit the NitrOS9 environment. I realize that that method is not for everyone; but like Nick Marentes, it just doesn’t “feel right” using modern cross assemblers, etc… I lose interest when all the retro feel is gone, which is what we had when we originally wrote it in the 1990’s). > On Mar 13, 2025, at 7:57 AM, Christopher R.
