YMT-Player v1.01 + Source by Peter Jørgensen (aka: Fedepede)

January 20th, 2015 No comments

YMT-Player is a player that allow you to play Project-Ymer YMT files (Windows) on the Atari ST. The program is made by Peter Jørgensen aka. fedepede.

What is Project-Ymer YMT files ?

YMT files are like the YM/AY files. Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player. Up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)

The advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo, when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc, and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc. It is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.

The zip archive contains the Floppy/HD version and Sources.

Changelog:

Ymt-Play Ver 1.01 Release Date 16.Jan.2015

  • Reactivate the clear screen function when the program start.. I deactivate it ,  so I could tested the program, but I forgot to turned on it again.

Repair Atari Falcon with a dead Keyboard

Repair Atari Falcon with a dead Keyboard.

Defect:

  • Dead Keyboard.

Repairing:

The defect was caused by a broken track in the third layer of the pcb, thus not visible. Missing the voltage of +5v from the component (L83) towards the pin four of the keyboard connector (J18) (circuit diagram).
I have made a small bridge for fix the problem permanently.

Atari 800 Boxed (UK-PAL) – Atari 810 Boxed – Atari 410 Boxed

December 26th, 2014 No comments
Atari 800 (UK-PAL)

The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 and manufactured until 1992. All are based on the MOS Technology 6502 CPU running at 1.79 MHz, roughly twice that of similar designs, and were the first home computers designed with custom co-processor chips. This architecture allowed the Atari designs to offer graphics and sound capabilities that were more advanced than contemporary machines like the Apple II or Commodore PET, and gaming on the platform was a major draw – Star Raiders is widely considered the platform’s killer app. Machines with similar performance would not appear until the BBC Micro in late 1981 and the Commodore 64 in 1982.

The original Atari 400 and 800 models were released with a series of plug-n-play peripherals that used Atari’s unique “SIO” serial bus system. Over the following decade several versions of the same basic design were released, including the XL and XE series of computers and matching peripherals. All of these used the same basic logical design, with various changes to the physical layout to lower production costs as chipmaking and manufacturing processes improved over time. The early machines were expensive to build, but dependable. Later models like the XEs were greatly cost-reduced and generally not as robust. Sub-models of these later designs were sold into the eastern European market after sales of the main lineup had ended.

Overall, the Atari 8-bit computer line was a commercial success, selling two million units during its major production run between late 1979 and mid-1985, putting its sales on par with machines like the Sinclair ZX Spectrum and TI-99/4A. Its primary competition in the worldwide market was the Commodore 64, by far the best selling computer of the 8-bit era. Atari also found a strong market in Eastern Europe and had something of a renaissance in the early 1990s as these countries joined a uniting Europe. Some estimates place sales during this period at another two million units.

The early machines: 400 and 800

Atari 800 (UK-PAL) Boxed

Management identified two sweet spots for the new computers: a low-end version known as Candy, and a higher-end machine known as Colleen (named after two attractive Atari secretaries). The primary difference between the two models was marketing;

Atari 800 (UK-PAL)

Atari marketed Colleen as a computer, and Candy as a game machine or hybrid game console. Colleen would include user-accessible expansion slots for RAM and ROM, two 8 KB cartridge slots, RF and monitor output (including two pins for separate luma and chroma) and a full keyboard, while Candy used a plastic “membrane keyboard”, non-accessible internal slots for memory, and only RF output for video.

Atari 810 Boxed

The Atari 810 Disk Drive was Atari’s first disk drive for its line of Atari 400/800 computers. Providing 88K of storage per disk side, the 810 gave Atari computer users the ability to quickly store and retrieve documents and program files to and from the storage device. Up to 4 Atari 810′s could be daisy chained together via the Atari SIO bus for a total of almost 360K of on-line random access file storage and retrieval.

The Atari 810 came in two different versions; the Tandon mech version and the MPI mech version. The Atari 810 is rather large compared to other companies disk drives and has an external 9Vac power supply. The reason why the drive is so large is that there is no disk drive controller in any of the Atari 400/800 computers, instead each device that connects to an Atari computer through its SIO bus is actually an intelligent device with its own intelligent communications controller and floppy disk controller.

The case design was conceived by Kevin McKinsey of Atari’s Home Computer Industrial Design group. The case is interesting in that the top and bottom covers are actually the same part made to assemble the top and bottom sides. Adhesive labels on the back of the 810 would block unused ports on the topside of the cover.

Atari 410 Boxed

The Atari 410 came in 2 different versions, the above shown is the Atari 410a Tawain version. The Program Recorder was well built and strudy with built in power supply and SIO cable, the 410 didn’t need a bukly external power pak like most other Atari 400/800 components, how the SIO cable being built in and the Program Recorder having no daisy chain port on the unit meant that it had to be placed at the end of the SIO chain.

The original idea of the SIO (Serial I/O) port on the Atari computers was that it was to be used only for the Data cassette drive, however its functionality was extended so that it could use all Atari peripherals including disk drives, printers and modem. The Atari 410/410a had a unique feature exclusively used by Atari. They could play two seperate tracks on a tape, this proved very useful for interactive programs where a user would run a program and would hear audio music/speech while the other track would load the next part of the program.

Commodore Amiga 500 (ASSY 312512 - REV 3)

I have received a Commodore Amiga 500 to use as spare parts. I decided to restore because it’s a ASSY 312512 (Revision 3) with key-switch like IBM chiclet keyboards.

The cleaning took me a whole day but with a great satisfaction at the end of the work. The Commodore Amiga 500 works fine, the floppy drive reads very well and i have added a memory expansion (FAST RAM) of 512k.

SNDH Atari ST YM2149 Archive v4.4 released.

July 3rd, 2014 No comments

SNDH archive v4.4 released – 4261 SNDH files (total 8268 tunes)

Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.

But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.

AspeQt v1.0.0 Preview-6 (Atari serial peripheral emulator for Qt)

June 12th, 2014 No comments

AspeQt is a cross-platform, free and open source Atari 8-bit serial peripheral emulator. The name is an acronym for Atari serial peripheral emulator for Qt, Qt being the cross-platform application development framework used by AspeQt.

AspeQt emulates various Atari 8-bit peripherals like disk drives and printers via an SIO-2-PC cable. If you are familiar with software like Sio2Pc, APE, Atari810, AtariSIO etc., you probably won’t have any problems getting used to AspeQt.

Even though AspeQt is not fully mature yet, it is easy to use and, despite its shortcomings, has many features that you may find useful, the highlights being:

  • Cross-platform GUI with drag and drop support.
  • 15 emulated disk drives with support for 512 bytes per sector disk images.
  • High speed operation up to 6 times faster than the normal speed (With compatible OS / DOS)
  • Ability to use PC folders as emulated disks.
  • Disk image explorer for viewing and modifying disk image contents.
  • Ability to run Atari executables directly without using disc images and Doses.
  • Printer emulation with preview and ATASCII support.
  • Cassette image playback with custom baud rate.
  • Ability to save and restore AspeQt sessions with its UI settings..=
  • Normal and mini UI modes.

Version 1.0.0 Preview-6 (May 23, 2014) (Ray Ataergin):

  • Windows registry entries for AspeQt are now stored under “atari8warez.com” registry tree, the program will automatically migrate settings on the next run. Existing AspeQt session files storing session settings are not affected by this change
  • Code needed to compile AspeQt under Mac OS X is added (David Voswinkel – optixx) (see compile.rtf file included with the source archive)
  • Folder images are now emulated in DOS 2.5 disk format rather than DOS 2.0 This gives more unique sector numbers to work with before they are re-used in a circular fashion.
  • Fixed the “Not a binary file” error loading certain executable files.
  • Text conversion is now OS platform aware (Win, Linux, OS X)
  • Explorer Window Stay-on-top feature is now user selectable and persistent across sessions.

Gotek (Cortex) USB Floppy Disk Drive Emulator

Gotek (Cortex) USB Floppy Disk Drive Emulator

Gallery:

The Gotek is a USB Floppy Drive emulator very cheap, you can buy it from eBay at €24.00 €20.00 including the shipping cost.

Let’s start by saying that this Floppy Disk Emulator with the original firmware is totally useless for our purpose, like to connect it to an Amiga and in the near future to a Atari ST or Amstrad CPC. The new firmware written by Herve Messinger replaces the original firmware, to do this you need a simple converter from USB to TTL Serial Interface to program the STM32 ARM Cortex MCU.

I would add this thing; this Floppy Drive Emulator is not absolutely comparable to the HXC Floppy Emulator of Jean-François DEL NERO (Jeff) where in addition to supporting dozens of Floppy Formats/Hardware and the Firmware is in development from several years but it’s a nice and inexpensive alternative.

For more information, firmware and programming tool you need to go here the official blog of Herve Messinger.
