8 bit designs gets a new website:
http://www.8bitdesigns.ath.cx/
The site should be more accessible to
C= users due to its design. This is
still a work in progress but the
design is looking good (well it looks
good to me)
HOXS 64 v1.0.5.10 15:24 &
Hey folks, the newest Version of the
HOXS64 is out. Check it at:
http://www.btinternet.com/{$de}hoxs64/
So whats new?
1) Fixed SounDemons sid emulation
compatibility that was broken in the
previous release.
2) Adjusted memory-reset pattern. An
optional memory pattern file called
c64.ram has been & added. The file was
sampled & extrapolated from the
memory-reset pattern of a C64C. If the
c64.ram file is missing then a default
pattern is generated.

The construction + future of the 1541
"Ultimate" Update December 14, 2007
A lot of work has been done to
integrate exciting new features &
improve ease of use of the 1541
Ultimate. The following text describes
the current status:
User Menu
When used as a cartridge on your C64,
the 1541 Ultimate now has a nice user
inferface, which can be started by
pressing the middle button on the
board. The current program that the C64
is running is frozen & a black screen
with a nifty blue bar appears, showing
the files & directories that are on the
SD-card. The 1541 Ultimate supports
FAT, FAT16 & FAT32 formats & also
supports long filenames (truncated to
22 characters to be able to show it on
a 40 column screen). By using the
cursor keys on the C= keyboard, the
user can travel quite smoothly through
the directories of the SD-card.
The 1541 "Ultimate"
This screen allows the user to select a
floppy image to mount (i.e. to change
floppy disks) or to create new floppies
or new directories. This makes it easy
to manage large numbers of floppies.
The menu also allows the user to change
the IEC address of the 1541 drive by
simply pressing 8, 9, 0 or 1. Since
this also resets the 1541 drive, it can
also be used for a manual reset of the
drive. In addition to mounting floppies
to the 1541 drive, the user can also
select separate program. These can be
loaded directly into the memory of the
C64, using DMA. Pressing R instead of
SPACE or RETURN to select the file even
runs the program immediately after
loading. This operation is possible on
separate programs, but also on files
within a .d64 or .t64 files (yes you
can browse .d64 & .t64 files as well!)
As you start using the 1541 Ultimate,
you will notice that it is faster than
you have ever seen before on any C64!
The user menu can be left by pressing
RUN/STOP, after which the C64 program
continues to run. Because the freezer
menu does not run on the processor
inside the C64 but on a separate 6502
on the 1541 Ultimate itself, returning
to the C64 program is smooth & safe.
Help! It is blocking my cartridge slot!
Yes, in order for your 1541 Ultimate to
work, it has to reside in the cartridge
slot. In order to minimize the
frustration, the 1541 Ultimate comes
with either the Final Cartridge III, or
the Action Replay cartridge installed.
Needless to say, the speed loaders that
are available in these cartridges work
together flawlessly with the emulated
1541 drive.
1541 Drive Emulation
This cycle-accurate emulation (or
implementation rather!) of the 1541
hardware, combined with an accurate
emulation of the floppy drive mechanics
offers the user a solid & easy to use
replacement of a real 1541 drive. It
uses an SD-card to store data; floppy
data is stored in .D64 images. These
images can be mounted on the hardware
of the 1541 ultimate, which means that
they are converted to GCR format, which
the 1541 can read from & write to.
Data written by the drive is converted
back from GCR to binary in parallel to
the operation of the drive & written
back to the .D64 file.
The 1541 "Ultimate"
Currently, I am investigating whether
it is useful to support .G41 files as
well, or any other format to store
floppies with custom format on the
SD-card. The drive emulation does not
put any restriction to the actual
format used (aside from it using the
GCR syncs, since that is something that
the 1541 hardware implements). If you
are using custom floppy formats, or
would like to use these with the 1541
Ultimate, please let me know.
IEC support
To serve other Commodore users as well,
other than C-64 users, the plan exists
to have this cartridge operate as
stand-alone unit, too. Since the
on-screen menu will not be available in
this case, the user needs another
method to select the floppy image. This
will be done by controlling the 1541
Ultimate through IEC; Commodores serial
port. Through IEC, the directories on
the SD-card can be selected, after
which the buttons on the board can be
used to switch between floppies within
the same directory. This allows
swapping disks within a program that
doesnt allow you to send IEC commands.
Note that this feature has not yet been
implemented.
Updates
New versions of the software & FPGA for
the 1541 Ultimate can be easily
distributed as one file, which is to be
put on the SD-card. Upon power-on, the
Boot-ROM of the 1541 Ultimate searches
for this file, & when present, it will
load & execute it. If not, it falls
back to the flashed version.

High-quality stickers for Commodore 64
Symbols for C64 are on non-transparent
black-mat stickers. Stickers are made
of high-quality black non-transparent
mat vinyl, thickness - 80mkn, typo-
graphical method. Applying stickers on
the keyboard properly once, you can be
sure that letters will stay forever.

PRESS PLAY ON TAPE is proud to announce
an upcoming concert:
On Saturday April 19th we'll be playing
another concert in Copenhagen at "The
Rock". The last two concerts there went
really well so The Rock wanted us to
come & play again :) Hope to see YOU
there! Tickets are available at:
http://www.billetlugen.dk
(search for "PRESS PLAY ON TAPE"). You
might think that we tell you this a tad
early but we want you to be able to
plan ahead, especially those of you not
living in Denmark. At the previous
concerts the doors closed during the
evening because the place was crammed
(that's more than 550 people), so be
prepared & buy your tickets in advance
:) Keep an eye on our event page for
up-to-date info about support band &

Music video:---
On top on that we can tell you that we
are working on a music video which is
going to be recorded (the video part,
that is, as the tune is recorded
already) next weekend. The video will
feature all the members of PPOT & more
with lots of computer graphics & post
processing. For now we don't know when
the video will be out but rest assured
that we'll post info about it on the
website & perhaps also send you another
mail on this list when it comes out.
The tune, you ask? That's a secret!
ROC=K ON!
