[FS: Low Cost high performance Hard Disk unit for Atari ST/E]

Low cost Hard Disk interface compatible with Atari ST family computers,
and tested on a 520ST TOS 1.04, 1040STFM TOS 1.04, 1040STE TOS 1.06, 1040STE TOS 1.62 and 1040STE with TOS 2.06; with ok results.

 

Performance: Around 1 MB/s Read, 650 KB/s Write

Operation video,

 

A video from the user PSIQ, many thanks!

 

 

Writing and reading from the hard disk interface:

 

 

On the last video, a game running from hard disk is shown; with "/" key, a savestate is created. After successful hard disk file writing, the game is closed pressing "*" key, and the STE system returns to desktop. A copy of the generated GS00.TOS file is created, renaming it to GS01.TOS; finally the game is resumed loading the copy of the savestate, GS01.TOS . All these operations are performed correctly.

Each unit is completely built and tested,
price is 36€ + tracked shipment (6.50€ for Spain or 10.50€ for Europe; 10.50€ for  EE.UU. , 12€ for Japan and Australia, Canada and rest of the world).

Lower cost and better SD card compatibility than any Satan disk, and much lower price than UltraSatan.
Its the Atari ST hard disk suitable for the masses,

An update, about tested micro SD card brands and types:

-Micro SD cards that work ok:

Sandisk de 1 GB
Kingston 8 GB class 4
Kingston 4 GB class 4
Intenso 8 GB class 4
Intenso 16 GB class 6
Intenso 4 GB class 10
Intenso 8 GB class 10
Kingston 16 GB class 10

[Metal Slug clone on Atari STE - First big attempt]

 

Greetings mates, lovers of Atari,

 

Some years ago I acquired a never used, a brand new (non opened box), Atari STE computer. That is really a great machine, heavily underrated machine.

Quickly I update it with 4 MB SIMM RAM modules... and I started on the search about how to program for it using C language...

some time after I reached this state:

 

 

This demonstration illustrates many of AGT libraries features, such fast sprite drawing routines, frame slipping, smooth scrolling and dualfield colouring technique, in order to increase the number of colours far beyond 16 usual ones.

It is designed and running on a standard 8 MHz Atari STE with 4 MB RAM at 50 frames per second. Loading from diskette is granted, but hard drive or new sd card reader for extended joystick port is easier and recommended. Due to games developed on this way requires plenty disk space; this demo loads up to 3.1 MB of data, 512 KB of them are used for music and fx effects, other 512 KB are needed to store the extremely detailed NeoGeo quality level map graphics; the rest of them are for sprites; where many animations are not yet programmed, but these frames are being loaded.

Sound is completely based on digital sound samples, mixed in a Real-Time manner; 3 voices at 12,5 KHz, arcade sound quality. The Yamaha YM2149 is not used in this example.

 

Original game code is not used here. Game code is programmed on C language using STE oriented libraries, the digital audio mixer is written on 68k assembly.

 

Original Metal Slug name, graphics and sounds/musics are property of their respective owners.
