SNDH archive v4.1 released – 3726 SNDH files (total 7003 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.

There are two differents emulators:
- A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
- A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.

I had several problems with the repair of the Hewlett-Packard HP-85.
The first problem was the way to reconstruct the pinch roller using a latex tube, this is a very bad choice, then i have used a 10mm heat shrink, this choice instead is very good.
The second problem was the rubber parts of the pinch roller are literally dissolved and the rubber is went to cover the optical diode and part of the pcb and of course nothing has worked and the tape drive was always in stalled state.
After cleaning, the drive started to work perfectly. The last problem are the magnetic tapes 3M DC-1000 instead of HP DC-100, for the correct operation you must perform a modification by adding a resistor of 2kohm in parallel to the already present on the pcb. After this mod you need to format the tape with the “erasetape” command.
I must also thank John of the site vintagecomputers.freeserve.co.uk for the support.

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:
- Up to 15 disk drive emulation.
- Up to 6x SIO speed (125,000bps)
- Support for ATR, XFD, PRO and ATX (preliminary) disk images.
- Mount folders as emulated disks.
- Disk image explorer.
- Directly boot Atari executables.
- Text only printer emulation with PC print, save, and ATASCII font support.
- Cassette image playback.
- Multilingual GUI (English, Polish, Slovak, German, Turkish and Russian)
- AspeQt client module (AspeCl) for Atari, communicates with the server and performs a variety of remote operations.
Changelog:
- Added an option (Options/Emulation menu) to selectively enable/disable filtering of underscore character from file names in Folder Images (Ray Ataergin)
- Fixed a problem where “Unmount All” menu item was only unmounting the first 8 images. (Marcin Sochacki)
- Updated Polish language translations (Marcin Sochacki – TheMontezuma)
