 |  Re: GEOS from EPROM? possible via emu and in real Plus/4
From your questions:
- No there is any previous version but 3.5;
- Many 2.0 applications (for c64) do work with 3.5; at cost of a little problem: the applications are not designed for colors managements, then they work with black foreground color, and with previous 3.5 applications background colors (a sort of shadows colors...). But in most cases the result is acceptable.
- Eh eh maybe, but it should need of much study on GEOS (disassamble, etc.). I have a good referring manual of 2.0. The 3.5 is a porting then there is much common.
The disk management is done by GEOS, then you can have 2 1551 disks online, normally the first one (named A) for GEOS system, and the second one (named B) for applications. I tried with 2 real units set as device#8 and device#9 and result is excellent.
You can switch from one to other being the desktop showing the content of the disk.
When do you start the project?
