- 1541 Ultimate II announcement
- Dear 1541 Ultimate enthusiasts,
-
- Some of you might have noticed that
- the order form has been temporarily
- closed, and many questions and
- rumors' have been going around about
- the future of the 1541 Ultimate. The
- reason behind all this, is that
- behind the screens I have been
- working on a successor of the "1541
- Ultimate". How this unit will be
- called has not yet been determined,
- but it could be something as simple
- as "1541 Ultimate II" or "Ultimate
- Cartridge".
-
- What is it, and why was it designed?
-
- Basically, it is a scaled down
- version of the 1541U. It will provide
- similar functionality, although some
- things have been changed. It will no
- longer support full-size SD-cards,
- but only MircoSD, or "Transflash".
- Also, Ethernet will not be supported
- until further notice. It will support
- tape emulation out of the box
- (without the need for special FPGA
- images) and it will provide a
- real-time clock function with battery
- back up. Audio output has been
- significantly improved, which might
- seem useless for just the drive
- sounds, but this enables the creation
- of FPGA images that provide
- additional sound channels of useful
- quality. The power consumption has
- been reduced as well. There is one
- extra cool feature that will not yet
- be disclosed ;-)
-
- And last but not least...
-
- This unit will come with a case! At
- least, that is the plan; there are
- some negotiations going on with
- manufacturers for plastic insertion
- mounding. It seems feasible to have
- this done, although it's pricy for
- low quantities. A prototype is
- 3D-printed this week; the prototype
- board is already there and functional
-
- Now, speaking of the case....
-
- Since I like to keep the high
- compatibility with the 1541, the big
- DIN connector is still there on the
- board. It might be an option to use a
- custom connector for this, with a
- custom cable that needs to be made
- for this unit, but to be honest; this
- does not have my personal preference.
- I would need to have these made
- separately, and stock them separately
- as well. So, let's say that the big
- DIN connector is a fact, how do we
- enclose this? There are two options;
- which are shown below:
-
- And the second option is:
-
- As you can see, the first one has a
- "strange" bulge, but is for the rest
- rather elegant, while the second one
- is symmetrical, but bulkier. Which of
- the two it should be, I don't know..
- Maybe I'll open a poll for this, what
- do you think?
-
- Availability: It will still take
- around 12 weeks before these units
- can be delivered; which means late
- October 2009. Price: I tried to keep
- the price acceptable. Due to the
- case, it has to go up just slightly
- though. The selling price including
- tax is ? 125; (excluding: ? 105).
-
- Please let me know what you think.
-
- Regards,
- Gideon
-
- Open sourced!!
-
- The software part of the 1541
- Ultimate is from now on Open Source!
- Although the hardware still needs to
- be documented, people can already
- check out the source code, edit it
- and build new applications for the
- 1541 Ultimate! The source is released
- under GPL 3.0, which in short means
- that every addition to the source
- code will also need to be open
- sourced and the code or parts thereof
- may not be sold. The full license
- agreement can be found in the 'root'
- (trunk) of the SVN archive.
-
- In order to build the software, you
- need to do the following:
-
- Install Cygwin, or run under Linux.
- Make sure you have:
- GNU make in order to run the
- makefiles.
- GCC compiler, in order to build the
- conversion tools.
- Install CC65 (http://www.cc65.org),
- and make sure you have the required
- environment variables and path set.
- Install a SVN client package (either
- command line in Cygwin) or a
- graphical client such as Tortoise SVN
- Check out the repository from
- http://svn.xp-dev.com/svn/gideonz_
- 1541Ultimate/
- Go to the trunk directory and type
- 'make'.
- At this point, the archive is
- read-only. If you are a developer and
- want to make a significant
- contribution to the 1541 Ultimate,
- please contact me and we can discuss
- being a write-user on the archive.
- Bug fixes from others can be E-mailed
- as patches, which I'd happily merge
- with the archive.
-
- Happy programming!
