This is a full replacement of the power supply of the Amiga 500 with a similar one of the last generation. This type of switching power supply fits perfectly inside the case of the original psu.

The repair will not be made because this psu is very common at very low prices, i don’t waste even a second to find the multiple faults, i prefer devote to other things less common.

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.

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.
