Today i picked up two Commodore 64, both are in poor condition and Broken.
The first one with the chip SID 6581 can play a garbled sound and the closing hooks broken, the other one with the chip PLA 906114, 7406, CIA 6526 dead. I made some cleaning and repaired the problems.

MSX was the name of a standardized home computer architecture in the 1980s conceived by Kazuhiko Nishi, then Vice-president at Microsoft Japan and Director at ASCII Corporation. It is said that Microsoft led the project as an attempt to create unified standards among hardware makers.
from Wikipedia:
On 27 June 1983, the date considered the birthday of the MSX standard, the MSX was formally announced during a press-conference, and a slew of big Japanese firms declared their plans to introduce machines. The Japanese companies avoided the intensely competitive US home computer market, which was in the throes of a Commodore-led price war.
Only Spectravideo and Yamaha briefly marketed MSX machines in the US. Spectravideo’s MSX enjoyed very little success, and Yamaha’s CX5M model, built to interface with various types of MIDI equipment, was billed more as a digital music tool than a standard personal computer.

DualSID KIT by Tomi Malinen:
DualSID is a device which allows you to plug in two different SID models to your Commodore 64.
You can set the second SID‘s address to five different memory locations. For more information and price visit the Tomi Malinen homepage

Thank to Lynx of Nightfall for your generous donation.
The Atari Lynx has several innovative features including its being the first color handheld, with a backlit display, a switchable right-handed/left-handed (upside down) configuration, and the ability to network with up to 17 other units via its “ComLynx” system (though most games would network eight or fewer players).
from Wikipedia:
The Atari Lynx is a 16-bit handheld game console that was released by Atari Corporation in 1989. The Lynx holds the distinction of being the world’s first handheld electronic game with a color LCD. The system is also notable for its forward-looking features, advanced graphics, and ambidextrous layout. The Lynx was released in 1989, the same year as Nintendo’s (monochromatic) Game Boy.
However, the Lynx failed to achieve the sales numbers required to attract quality third party developers, and was eventually abandoned. Today, as with many older consoles, there is still a small group of devoted fans, creating and selling games for the system.

I had to make this change to get the Expansion Ram 320XL running on my Atari 800XL:
source: atariage.com
Autopsy:
The Expansion Ram 320XL is a external plug and play 320kB memory expansion card for Atari 600XL and 800XL machines designed by ctirad a user of AtariAge Forum.
Additionally there is a possibility to disable internal memory and remap it onto card (switchable via jumper), thus one can “fix” many failing XLs without even looking inside. Also, an unexpanded 16kB 600XLs can be upgraded to 320XL without any additional work.
The Expansion Ram 320XL uses banking via bits 2,3,5,6 and 4 of PORTB. As you can see this is compatible with “Atari magazine” expansion rather than a most common RAMBO or Compy shop setup, however I have to say the comaptibility with both old and new software is excellent. There can be only problem with some programs, which does use the separate Antic/CPU banking.
The Installation is very easy. The Atari 600XL users will just plug it into PBI port. For Atari 800XL is a bit more complicated, because Atari decided to remove 5V power from the PBI connector from it. Thus 800XL users will have either to use additional power cable which will fit into joystick port or solder one wire inside atari to make the PBI port powered like on 600XL (look photo).

Today i picked up a Commodore 64c Family Pack Edition with Powersupply / Datasette & Joystick in good working condition. The plastics of the Commodore 64c and Datasette are little yellowed but does not affect the right use.
Micro SwinSID KIT by Peter Sieg:
Certainly you can’t expect perfect emulation, but we are very close, the audio is much more clean than the original SID chip, if the project continues on this road we will arrive very soon on the perfect emulation.
Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer.
This project is based on the microcontroller ATMEGA88PU from Atmel and the emulation code is written by Swinkels. The first version of the pcb (prototype) was made by Crisp.

The Philips P2000T home computer was Philips’ first real entry in the home computer market, after the Philips Videopac G7000 game system (better known in the U.S. as the Magnavox Odyssey2) which they already sold to compete with the Atari 2600 and similar game systems.
There was also an P2000M version with an additional 80-column card for use with a monochrome monitor. This version shipped with a monitor cabinet also housing a dual 5.25″ floppy drive. Basically the P2000T was a Z80 based home computer that used a Teletext display chip to produce the video picture and a small Mini Cassette recorder for mass storage (42 kByte).
The mini cassette was seen as a floppy drive from the user perspective using the automatic search for a program (CLOAD command) or free space (CSAVE). A command to display the directory of the cassette does also exist. Philips used components they already produced for other markets (television sets and dictation machines) to quickly design a small computer system. It was partially designed by Austrian professor Dieter Hammer.
They also copied the ROM cartridge system from their Videopac G7000 game system. One of these cartridges contained Microsoft BASIC. It was also possible to use cassette tape floppys.

from Wikipedia:
The Atari Portfolio is the first PC-compatible palmtop computer, and was released by Atari Corporation in 1989. The Portfolio was licenced from Distributed Information Processing (DIP) based in Guildford, Surrey, England. The original founding member of DIP was Ian Cullimore, fresh from his experiences at helping design the early Organiser products at Psion.
DIP officially stood for “Distributed Information Processing”, although secretly it actually stood for “David, Ian and Peter”, the three founding members of the company, all ex-Psion. The original founder of the company (first called “Crushproof Software”) was Ian Cullimore, and the other two David Frodsham and Peter Baldwin. It was built around an Intel 80C88 CPU running at 4.9152 MHz and ran a variant of MS-DOS called “DIP DOS 2.11″. It had 128 kB of RAM and 256 kB of ROM which contained the OS and built-in applications. The on-board RAM had to be divided between system memory and local storage (the C: drive). The LCD was monochrome without backlight and had 240×64 pixels or 40 characters x 8 lines.
