# A2osX Media Guide
### Updated December 5, 2019
### Updated January 26, 2020
We have changed the media set for A2osX. New A2osX Users should download the most current version as shown in the table below. **A new Release Candidate (RC) edition has been made available (highlighted below), you should choose one of the media options from this set.** The Bleed media are the primary images used by the developers to hold the most current version of the A2osX binaries (and a copy of the source, although of course GitHub is the primary source repository) and may be unstable. You should not use this media unless directed by the A2osX development team.

## ProDOS Versions
The A2osX team has developed and now includes on its media new versions of ProDOS for use with A2osX. Please consult the document **[A2osX and ProDOS](.Docs/ProDOS.md)** for detailed information on these versions. Briefly there is ProDOS 2.03tc which is an 8 byte patch to ProDOS 2.03 to update the year table to support years through 2023 and ProDOS FX a **F**aster and e**X**tended version that adds many new features including lower case file, directory and volume name support. These new versions are already being included in the latest **Stable** media and will become the versions of ProDOS supplied on all future media. The ProDOS 2.03tc version is included on the 800K media images listed above and provides the maximum compatibility with existing systems. The ProDOS FX version is included on the 32MB media images which are designed to be standalone bootable images. In addition, there is a very special ProDOS FX PAKED version, that is the same as the standard FX image once running, but the file has been compressed and contains a special loader to uncompress ProDOS as it initializes. This version uses less disk space and is used on 140K media where space is at a premium.

## New A2osX ProDOS Versions
The A2osX team is proud to announce the availability of two new versions of ProDOS, one with a very minor tweak and the other a major update/overhaul. These are discussed in detail below, but briefly there is ProDOS 2.03tc which is an 8 byte patch to ProDOS 2.03 to update the year table to support years through 2023 and ProDOS FX a **F**aster and e**X**tended version that adds many new features including lower case file, directory and volume name support. These new versions are already being included in the latest **Stable** media and will become the versions of ProDOS supplied on all future media. Please consult our **[Media Guide](.Docs/Media%20Guide.md)** for more information about which version is included on each media image.
## Tested Versions
ok, back on Prodos…. I am going to close saying, we test both 2.03 and 2.42. people can use what they like (look at User Guide on installing a2osx on your own HD/booting your own prodos). Have nice day. Nothing to be said of FX. I think one question to answer in future is when you do ProDos FX, will a2osx stop working on standard prodos?
For 0.93, the current project milestone, we have decided to include on the A2osX media a very slightly modified version of 2.0.3 which you will notice during boot of ProDOS is labeled as 2.0.3tc. This stands for ThunderClock and basically this version is an exact copy of 2.0.3 with 7 bytes changed to update the ProDOS year table to be current (it is the same work to correct the year that is done in 2.4.2/2.5 by John Brooks). Note, we do test A2osX regularly with other versions of ProDOS (the author of this note regularly runs 2.4.2). For consistency and support we will standardize on 2.03tc for this release and readdress which version of ProDOS should be included when we start creating 0.94 builds.
Also note, users can replace ProDOS with another version, or as is expected for many with hard drives/emulators, they can install A2osX onto a subdirectory of their HD/Drive which boots their preferred version of ProDOS. In fact, we are planning for an upcoming release an “INSTALL” method that will create this subdirectory, copy the necessary files and make any changes to A2osX config files needed so people can run A2osX in this manner.

Drive Remapping
### Drive Remapping
With the release of ProDOS 8 (Version 1.2) Apple Modified the ProDOS 8 loader code to automatically install up to four drives in slot 5 if a SmartPort device is found using slot 2 for the extra 2 drives. With ProDOS 8 Version 2.0.1, ProDOS supports more than two SmartPort devices per slot by remapping the third device and beyond to different slots. There's still a limit of 14 devices altogether, though.

WHile you are on that.... I am working on an updated readme to go with next RC.... I am going to talk about new FX and how it supports LC (I think we need to talk more about FILE file File fILe...) and more info about FX.PAK on 140K media. Is there anything else in FX to note [oh SP drive mapping stuff from produs enhancement channel). Also in readme new PAK/UNPAK, TERM, ask for more devs, testers, especially with HW, and some doc readers would be nice. Further on Pdos, say we have tested on 2.5a8 and works, unsupported at this time (you can file issue but may not be addresses). known that date display in LS no work becasue 2.5 breaks standard and we may not adapt. 8 drive per slot "?works" but a2 reports multiple drives as D1/2 and again non-standard we may not change/adapt to. so basically use 2.5 at own risk at moment. What else should be talked about?

### ProDOS 16 / GSOS
ProDOS 16 / GSOS
am writing right now a ProDOS.md doc that will discuss 203tc, FX, and support of other versions out there.
That was why i was asking about ProDOS 16. I was wondering if there was anything I needed to test/write up anything related to 16.
there s something about launching A2OSX.SYSTEM under GSOS
not supported
because of very sensitive IRQ managment in A2osX
ProDOS 16 / GSOS are versions of the ProDOS operating system that run only on Apple //GS computers. At this time, A2osX is not supported under these operating systems because of A2OSX.SYSTEM's very sensitive IRQ management required by the multitasking multiuser nature of A2osX. To run A2osX on an Apple //GS you must first switch to one of the supported ProDOS 8 versions such as the supplied ProDOS 2.03tc or ProDOS FX.
## Requirements
All editions of ProDOS require an Apple II series computer or licensed compatible.
ProDOS 8 requires 64kB of memory to run. The original ProDOS (8) 1.0 through 1.0.2 requires only 48kB for the kernel, but nearly all programs, including the BASIC.SYSTEM needed to use Applesoft BASIC, require 64kB, making a 48kB system useless for ProDOS as a practical matter, and support for 48kB machines was removed in version 1.1.

ProDOS 2.03tc has the exact same requirements as ProDOS 2.03 since its only difference are the eight patched bytes to the date/year table.
ProDOS FX requires a 64KB 65c02 or later CPU. ProDOS FX will not run on a Apple ][ or ][+. Note, however, that A2osX itself requires a minimum of 128kB to operate.
