SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 microcontroller from the Atmel AVR microcontroller family.

The most prominent use of SD2IEC is emulation/replacement of a Commodore-1541 disk drive for a C64. Hardware and the microcontroller’s firmware is available as open source (GPL).

The High Voltage SID Collection web page is totally renewed. Especially the Search part is much improved.

You can for example type-in “Rob Hubbard” and you will be presented with a complete list.

It has been over four years since the latest release of our disk magazine. Finally “Attitude #10″ is ready for download. Get your copy and tell us if it was worth to get together again and make this release possible.

We hope you enjoy this issue as much as you did the previous ones!

General Info:

• Firmware written primarily for the DivIDE interface, maybe for others in future.
• Inspired by our (Phoenix & LaesQ) old ‘backbone’ project + inspiration from +D
• Works with HDD/CD-ROM/ZIP/LS120 (LS120 can access 720KB and 1.44MB floppies)
• Uses drivers to access filesystems (either in RAM or ROM)
• Provides new BASIC commands
• Will provide RST 8 hooks for user-land apps
• Supports IM2 loading/saving (K3L’s FA part)
• Drivers give access to the filesystem, and provide specific emulation hooks in certain cases (TRDOS, .TAP, etc)
• There’s a device/filesystem abstraction layer, which means that BASIC or user-land programs don’t need to know anything about the underlying filesystem/device (ie, you use the same BASIC commands for all filesystems, FAT/ISO/TRD/etc)
• Will allow up to 4 virtual drives for disk images (.trd/etc)
• Filesystems are mapped acording to type: hd*, fd*, cd*, vd*, td*
• FAT12/16/32 driver built-in ROM, other drivers loaded from boot filesystem on demand. (on this preview version, there was still room so TRDOS filesystem is in ROM too)
  Does not need a system file to work, common BASIC commands and FAT driver on ROM, system file loaded from boot filesystem will have additional commands, etc.
• … more stuff which I prolly forgot

Island of Secrets Graphic Adventure – 22 column version by Jenny Tyler and Les Howarth.

This game is a conversion from Commodore 64 of a classic type-in text adventure from the book published by Usborne in 1984. Play it with the stunning graphic excitement of more than 30 hi-res screens! It’s require a VIC-20 + 24K RAM.

This program is basically a utility created to edit your D64 files.  Hopefully when it is done it will have all of the features you’d expect from a c64 based disk editor, as well as additional features that make it easier to manage your D64 files.

Here some features:

• Read D64 files, display the directory, move files around the directory, rename files.
• Export files from the D64 into PRG files.
• Import files into the D64 with autodetection for P00 files.
• View/Edit the BAM.
• View the block chain of files on the D64.
• Create new blank D64 files, clean existing D64′s.
• View and modify blocks on the disk in hex.
• Automatic check for crosslinked files on the D64.
• View the directory using the native c64 font.
• SEQ File Viewer using the c64 font with PETASCII->ASCII conversion option.
• Drag and Drop functionality. Drag D64′s onto the main screen to load them, drag other files to import them.
• Preliminary support for importing T64′s.
• A filename builder to enable easy use of the C64 Characterset in filenames.

ACID 64 Player Pro is the sequal of Acid 64 Player and is a cycle based Commodore 64 music player designed for playing SID tunes on sound cards/devices that have a real SID chip (6581/6582/8580) on board like the HardSID cards and HardSID 4U USB device.

ACID 64 emulates the MOS 6510 micro processor, the 6526 CIA chip and partially the 6569 VIC chip to run the code of a SID tune and it controls the SID chip on the device for playing the Commodore 64 music.

What’s new in version v3.0.3:

New:

• Support for the new HardSID USB devices: Uno and UPlay.
• Auto detection of turned on/off USB devices.
• Added sorting on column of every grid.
• Emulated SID reading.

Improvements:

• When performing e.g. mute/unmute, filter on/off or pause then no time gap isn’t noticed anymore while playing on a USB device.
• Seek bar is always going smooth now and still synched with the 6510 CPU clock.
• Improved fast forward.
• HardSID.dll isn’t required anymore for USB devices.
• Many small improvements.

Fixes:

• Works now without administrator rights.
• When using dual monitor ACID 64 will now be centered on the screen instead of the desktop.

PONG is one of the earliest arcade video games, released by Atari way back in 1972. (It was not the first video game, but it’s venerable indeed.)

We’re certainly not the first to build a real-world analog of a video game or even of PONG itself.

from 1541 Ultimate homepage:

Finally, you might think! An update on the 1541U-II… As time is going fast, the moment that all the hardware parts for the 1541U-II will be ready is drawing near. It all was not too easy, but things are going now the way they should.

The major difficulty showed to be the plastic case. Finally I have found a contractor who is willing to make the plastic case exactly as I wanted it, for a reasonable price. Unfortunately, the mould for plastic injection is quite expensive; in fact about double of what I expected initially, based on an unrealistic quote that I got a few months ago. Because of the large interest in the 1541U-II, I decided to just continue with it, and leave the selling price of the total product intact.

Earlier this week, I received the first pictures of the first try-outs of the injection mould tool. The result shows a little problem in the design, with the planned material (ABS). Due to the thick and sturdy plastic constuction on the inside, sink marks are visible on the outside.

The manufacturer has tried to run the case with a different material (PA), which looks a lot better. However, due to different shrinkage characteristics, the mould tool needs to be adapted to adjust for the difference in material. (You can see this, that the matte version does not close perfectly…) They will do this, but it will take one week extra before the cases are ready. The final color won’t be black (unless I am getting a lot of angry E-mails now.. ;-), but light cream color, to match the C64C better.
