petSD is the name of the new AVR-based hardware. It’s a modern mass storage solution for Commodore PET/CBM computers with IEEE 488 bus using SD cards as floppy or hard disc replacement.

If you know the SD2IEC or µIEC: the petSD is just the same but for the older parallel IEEE 488 bus instead of the newer serial IEC bus.

The petSD is still a work in progress and there still are some issues.

A petSD consists of at least:

• ATmega 1284P.
• Red and a green LED (may be combined in one).
• SD slot.
• IEEE 488 connector.

The Hybrid SID is a portable SID Player with a OLED LCD and a USB connector.

The Hybrid SID plays the most common variety of chiptunes, music written for playback on a SID chip. Probably the biggest collection of SID music is the High Voltage SID Collection, which has 36,000 SID tunes, free to download.

This prototype use a real SID chip (6581/8580) for play music and a CUI32 PIC32MX Development Stick for the CPU (6510) Emulation.

A new version of the firmware for the interface 1541 Ultimate II is released. This version only runs on the Ultimate-II! Release for Ultimate-I (MK1) will come very soon.

Major improvement in latest release:

• MAJOR bug fix: Updater caused to unit to fail when “Force update” was selected on the first batch Black boards (with Atmel Flash)…
• Updater updated: Now possible to clear all configuration pages in flash.
• Issue fixed with configuration of objects that did not have a config page yet (write/effectuate decoupled).
• Issue fixed with re-freezing into an empty D64 (or file with headers but no items); caused a blank screen.
• Version number of FPGA increased [to $A6], because REU was fixed. (See previous commit).
• Simulation environment set up for REU.
• REU verify bug fixed. More testcases to be added.
• …/target/simulation/sim/$ make reu_tc_1.gui will start ModelSim with the REU testcase.
• Missing simulation package added.
• SdCard cannot be renamed, of course… fixed…
• Build of MK1 firmware fixed, using the 250E FPGA.
• Makefile changed to output a warning when ISE locations from the project is used, instead of your own.
• Tested on ‘clean’ system with Xilinx ISE 13.1 installed.
• Missing file added: sid_mapper.vhd. Why did nobody notice this? :D

This program converts images to a new c64 graphic format known as MUCSU FLI (MUltiColor Sprite Underlay FLI). It is merely a hiresolution bitmap image with an X expanded multicolor sprite underlay. The Hires underlay variant of this mode has been created before (known as extended hires).

After reading a few forum posts mentioning that the multicolor version of this mode was unrealistic and would provide too many restrictions, I decided to produce this converter to prove that this is not the case as well as wanting to use this particular format for my own production.

TURGEN SYSTEM is an acronym for “Turbo generating system”. It is a program whose main purpose is conversion of files (with focus on binary files) to various turbo systems used in former Czechoslovakia and Poland.

Output of the program is an electric signal that can be stored in WAVE files or can be sent directly to computer’s audio system. Such electric signal can be then transferred to compact cassettes and read by data recorders equipped with particular turbo system.

TURGEN SYSTEM focuses on conversion of binary files. For such purpose, set of special miniature turbo loaders was developed and integrated to the program. Also a “Wizard for binary files” is available to provide convenience during the conversion preparation.
