I have decided to upgrade my Amiga 2000 PAL REV 4.5 for get 1MB of chip ram. I also took advantage of this update to install a new battery for the system clock. Amiga 2000 PAL REV 4.5 Fat Agnus 8372A Installation:

• Install a new Fat Agnus 8372A or 8375 (8375 R1)
• Look for jumper J101 beside the power connector to the motherboard. Change it to the opposite position. (photo)
• Look for trace J500 at the back of the machine near the Cia’s (8520′s). It’s a jumper trace that you will have to cut with a razor blade. (photo)
• Look for trace J102 near the Fat Agnus (8372A). It’s a jumper trace that you will have to cut with a razor blade. (photo)

My new desoldering station and a magnifying lamp has arrived!

After some frustrating times removing solder on an almost 30 year old PCB i decided to get a desoldering station.

So after using this for a few hours what one word can I use to describe this station? AWESOME! I don’t know how i lived without this in the past. Using desoldering braid or a soldapullt is OK but not consistent.

Package content of Aoyue 474A+:

• 474 Station.
• Desoldering Gun.
• Filter pads 6pcs.
• Silicone Grease.
• Filter pipe.
• Nozzle cleaning pins.
• Power cord.
• Desoldering gun holder.

Today i picked up a Commodore Amiga 2000 (Revision 4.5) in good working condition with Keyboard and Mouse.

I have removed the battery and thoroughly cleaned the PCB in that area. I noticed that the PCB is pretty delicate when trying to unsolder. The solder mask becomes damaged when exposed to too much heat for too long, and probably one would easily kill leads unless being extremely careful. Maybe the board’s age adds to it.

from Wikipedia:

The A2000, also known as the Commodore Amiga 2000, was released in 1986. Although aimed at the high-end market it was technically very similar to the A500, so similar in fact that the A2000B revision was outright based on the A500 design.

What the A2000 had over the A500 was a bigger case with room for five Zorro II proprietary expansion slots, two 16-bit and two 8-bit ISA slots, a CPU upgrade slot, a video slot, and a battery-backed clock.

It should also be noted that, like the Amiga 1000 and unlike the Amiga 500, the A2000 came in a desktop case with a separate keyboard. The case was more PC-like than the A1000 – taller to accommodate the expansion cards and lacking the space beneath for the keyboard.

This pong from Philips (1977) is a bit special. It uses the unusual AY-3-8550 from General Instruments. This chips offers 4 classic pong games (Tennis, Squash, Squash practice, Football) and 2 shooting games. The paddles can be moved verticaly AND horizontaly, hence the analog joysticks (instead of the classic sliders). The display is in color.

There is a female DIN plug at the bottom-right part of the case. It is used to connect an optional light-gun to play the two shooting games.

There are switches to control the different options like ball speed, paddle size, angle 20°/40°, manual/auto service. There are two buttons: reset and serve. There is even a TV channel selection knob to adjust the picture on the TV.

The Las Vegas ES-2208 is in fact one of the Las Vegas pong systems from Philips. Here is the list:

• Las Vegas Tele-Spiel ES-2203 (6 games, black & white display, vertical movements)
• Las Vegas Tele-Spiel ES-2204 (6 games, color display, vertical movements)
• Las Vegas Tele-Spiel ES-2208 (6 games, color display, vertical & horizontal movements)
• Las Vegas Tele-Spiel ES-2218 (8 games, color display, vertical & horizontal movements)
• Travemünde Tele-Spiel ES-2207 (4 games, black & white display, vertical movements)

I bought one month ago a AtariMax 8MBit Cartridge for Atari that had the wrong label on it, it is a 1mbit in place of a 8mbit.

This is a free replacement 8mbit cartridge from Steven J.Tucker (AtariMax).

Many Thanks Steven.

This is my Commodore Amiga 3000. I used this computer for many years, example: for my BBS “Hidden Power“, coding Amiga / Snes Demos & Trainer and other fun stuff.

I decided to pull out of the box and try if still works, i must say that everything works like 15 years ago (including the Harddisk).

Description:

• Commodore Amiga 3000 rev B2.
• MultiFaceCard III (multi Serial Ports)
• GVP Card with 8 Mb of Fast Memory installed.
• Removed the original Battery.

from Wikipedia:

Released in June 1990, The Commodore Amiga  3000 was the third major release in the Amiga computer family. It revealed a much more focused and sincere attempt to build a high-end professional multimedia computer, boasting improved processing speed, better rendering of graphics, and a revision of the increasingly haggard operating system.

Its predecessors, the Amiga 500,1000 and 2000, shared the same fundamental system architecture and consequently performed without considerable variance in processing speed despite considerable variance in purchase price. The A3000 however, was entirely reworked and rethought as a genuine high-end workstation.

The new Motorola 32-bit 68030 CPU, 68882 math co-processor, and 32-bit system memory helped increase the “integer” processing speed by a factor of 5 to 18, and the “floating point” processing speed by a factor of 7 to 200 times. The new 32-bit Zorro III expansion slots provided for faster and more powerful expansion capabilities.
