from Wikipedia:

The Amiga 500, also known as the A500, was the first “low-end” Commodore Amiga 16/32-bit multimedia home/personal computer. It was announced at the winter Consumer Electronics Show in January 1987, at the same time as the high-end Amiga 2000, and competed directly against the Atari 520ST. The A500 was released in mid 1987 at the price of 595.95 USD without monitor.

Island of Secrets adventure for VIC20, 40 cols (+24K)

February 17th, 2009 No comments

islandofsecretsFAT40 and Orion made a VIC20 version of the game Island of Secrets.

The game itself is simple and the parser limited, but the atmosphere is good, thanks also to the excellent manual, with comic-style drawings and nice descriptions.

Commodore SX 64 with some Fix/Enhancement

February 15th, 2009 27 comments



  • Country: USA
  • Most Common: USA/Europe
  • Rarity: Very rare
  • Year: 1983
  • Price: $995


  • Added a Fan.
  • ASSY fix from Commodore.
  • I/O Fastloader fix.
  • Userport GND  fix.
  • Jiffy Kernel (C64/1541).

from Wikipedia:

The Commodore SX-64, also known as the Executive 64, or VIP-64 in Europe, was a portable, briefcase/suitcase-size “luggable” version of the popular Commodore 64 home computer and holds the distinction of being the first full-color portable computer.

The SX-64 featured a built-in five-inch composite monitor and a built-in 1541 floppy drive. It weighed 23 lb (10.5 kg). The machine was carried by its sturdy handle, which doubled as an adjustable stand. It was announced in January 1983 and released a year later, at $995.

Sega MasterSystem II + Alex Kidd

February 14th, 2009 1 comment


The Sega MasterSystem II was originally designed to output an RF modulated (VHF) signal but with a mod you can get a better signal with the Composite Video .


  • Country: Japan
  • Most Common: Usa/Europe
  • Rarity: Unrare
  • Year: 1990

from Wikipedia:

The Sega Master System is an 8-bit cartridge-based video game console that was manufactured by Sega and was first released in 1986.[3] Its original Japanese incarnation was the Sega Mark III (although the “Master System” name has also been used in Japan).

In the European market, this console launched Sega onto a competitive level comparable to Nintendo, due to its wider availability, but failed to put a dent in the North American and Japanese markets. The Master System was released as a direct competitor to the NES/Famicom.

Commodore Amiga 1200

Amiga 1200 Top Side



  • Country: USA
  • Most Common: USA/Europe
  • Rarity: Unrare
  • Year: 1991-92

from Wikipedia:

The Amiga 1200, or A1200, was Commodore International’s third-generation Amiga computer, aimed at the home market. It was launched in October 21, 1992, at a base price of £399 in the United Kingdom and $599 in the United States. Initially, only 30,000 A1200s were available at the UK launch.[1]

Like its predecessor, the Amiga 500, the A1200 is an all-in-one design incorporating the CPU, keyboard, and disk drives (including, unlike the A500, the option of an internal hard disk drive) in one physical unit. The machine was designed to be able to house a 2.5inch HDD internally, but it was possible to mount a 3.5inch HDD inside the 1200 if a little brute force was used.

uIEC/SD v3.0 Now available!

February 9th, 2009 No comments

from: Petscii Forums “PETSCII.COM”

I held off on announcing uIEC/SD availability until I had some stock (impatient folks, you know who you are , but I do now have some stock 90 units).

Since uIEC shares the same firmware (kudos to Ingo Korb, who does not get enough recognition for this fine piece of code) as the recently announced SD2IEC, I’ll spare everyone rehashing the similarities and just note the differences:


  • uIEC/SD is currently the smallest known CBM drive (1.5″ x 1.5″ by 0.3″). Perfect for embedding in your favorite machine, drive, or calculator (shout out to Tone007, who stuffed one in a CBM pocket calculator)
  • uIEC/SD shares the same 128kB Atmel AVR 8-bit microcontroller as the rest of the uIEC line. With 51kB used for firmware, there’s plenty of room left for the future.
  • uIEC/SD comes complete for use with IEC connector and power supply cassette port connector. VIC/64/C128 users can simply plug the wires in and use. (SX64/+4/C116/C16 users need to source 5V elsewhere, let me know before purchasing if you’d like an alternate connector)
  • Although not yet defined for use, uIEC/SD offers an additional switch line and programmatic LED for future use.
  • uIEC/SD not only supports SD and SDHC cards, but either SD or SDHC cards can also be used for updating the firmware (new feature, older firmware update software only supports SD cards)

SHO-FLI Converter Update 2 – (C) 2009 Algorithm / Algotech

February 8th, 2009 No comments

SHO-FLI (Sprite Hires OVerlay FLI/Sprite OVerlay Hires FLI) is a custom c64 graphic mode which features a hiresolution spriteoverlay in one color over a FLI image.

It works in exactly the same way as the SHFLI mode but the image data is wider due to using 1 sprite overlay (rather than two in SHFLI) – This GFX mode is also known as SHF-XL originally invented by Crossbow/Crest. I created this Application because this gfx mode is rather awkward to paint in.  Plus there does not seem to be any converters released.


UPDATE 2 – 07/02/09

  • YUV perceptual conversion now nearly 5x as fast.
  • Displays pixel error percentage of final rendered image in comparison to attributeless 16col c64 conversion.
  • Correct extension now automatically appended to filename.


WhackE for Commodore VIC-20

Find your way through the dungeon levels and bring the Amulet back to the surface. Watch out for fierce guardian Demons and other creatures living in the dungeons.

Use the cursor keys to move. Move towards a monster to attack it. Any items are picked up when you walk on them.

FPGA – C64 PLA Replacement

February 7th, 2009 2 comments

The PLA chip (906114-01) used in the Commodore C64 is a generic 82S100 gate array with custom programming. Its logic functions were dumped and reverse engineered by the community and are available from a variety of sources. They’re reused for this particular PLA replacement in the FPGA Arcade 28 pin DIL CPLD board.

Two approaches exist to build such a PLA replacement:

1. Implementation based on a truth table with 216 entries, each entry consiting of 8 bits and programmed into an EPROM chip.
2. Reverse engineered logic equations programmed into a PLD.

Both approaches result in the same logic functionality when implemented in a CPLD. Since equations are more common for CPLDs, I chose this implementation style for the final design. However, there’s a variant for the truth table available which has been verified in simulation but not in real C64 hardware. Following are descriptions for both of them.

We have run simulations proving that the equations perfectly match the truth table, so both compiled outputs are effectively identical in the C64 implementation discussed here.


durexForth (Forth for Commodore 64)

February 7th, 2009 No comments

Forth, the Language.

Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.

It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.
