Repair Atari Falcon with a dead Keyboard.
Defect:
Repairing:
The defect was caused by a broken track in the third layer of the pcb, thus not visible. Missing the voltage of +5v from the component (L83) towards the pin four of the keyboard connector (J18) (circuit diagram).
I have made a small bridge for fix the problem permanently.

The High Voltage SID Collection (HVSC) is a freeware hobby project which organises Commodore 64 music (also known as SID music) into an archive for both musicians and fans alike.
The work on the collection is done completely in the Team and contributors’ spare time and is proudly one of the largest and most accurate computer music collections known.

YMT-Player is a player that allow you to play Project-Ymer YMT files (Windows) on the Atari ST. The program is made by Peter Jørgensen aka. fedepede.
What is Project-Ymer YMT files ?
YMT files are like the YM/AY files. Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player. Up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)
The advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo, when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc, and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc. It is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.
The rar archive both contain a Floppy and a HD version.

This a special edition of the Commodore C64, celebrating the 1.000.000th sale of the C64 in Germany. This is one of the most desirable Commodore items. There are about 300 golden Commodore C64 produced. The numbers from 1.000.000 until 1.000.100 were for the staff of the Commodore factory Braunschweig.
The rest was given to hard- en software companies, magazine-publishers and distributors. The C64 is a computer system with a keyboard, external power-supply and a motherboard. On the motherboard you will find a MOS 6510 processor, RAM / ROM memory, MOS 6569 VIC-II video chip, MOS 6581 SID sound chip and twice a MOS 6526 CIA. PAL version.

Repairing keyboard Apple ///:
It seems incredible but there is always a button that doesn’t work ;-D
I found on some keyboards of the TI-99/4A the same buttons but with the plunger much smaller. I have used the plunger of the Apple /// button on the TI-99/4a button and i have fixed the problem elegantly ;-D
Thank to my friend Ninetyniner Iuc for the donation of spare parts.

The Apple III (often rendered as Apple ///) is a business-oriented personal computer produced and released by Apple Computer that was intended as the successor to the Apple II series, but was largely considered a failure in the market. Development work on the Apple III started in late 1978 under the guidance of Dr. Wendell Sander. It had the internal code name of “Sara”, named after Sander’s daughter. The machine was first announced and released on May 19, 1980, but due to serious stability issues that required a design overhaul and a recall of existing machines, it was formally reintroduced the following autumn. Development stopped and the Apple III was discontinued on April 24, 1984, and the III Plus was dropped from the Apple product line in September 1985.
The Apple III could be viewed as an enhanced Apple II – then the newest heir to a line of 8-bit machines dating back to 1976. However, the Apple III was not part of the Apple II line, but rather a close cousin. The key features business users wanted in a personal computer were a true typewriter-style upper/lowercase keyboard (as opposed to the Apple II which was based on a teletype keyboard) and 80 column display. In addition, the machine had to pass U.S. Federal Communications Commission (FCC) Radio Frequency Interference (RFI) qualifications for business equipment. In 1981, International Business Machines unveiled the IBM Personal Computer (IBM PC) – a completely new 16-bit design soon available in a wide range of inexpensive clones. The business market moved rapidly towards the PC DOS/MS-DOS platform, eventually pulling away from the Apple 8-bit computer line.
Despite numerous stability issues and a recall that included the first 14,000 units off the assembly line, Apple was eventually able to produce a reliable and dependable version of the machine. However, damage to the computer’s reputation had already been done and it failed to do well commercially as a direct result. In the end, an estimated 65,000–75,000 Apple III computers were sold. The Apple III Plus brought this up to ~120,000. Apple co-founder Steve Wozniak stated that the primary reason for the Apple III’s failure was that the system was designed by Apple’s marketing department, unlike Apple’s previous engineering-driven projects. The Apple III’s failure led to Apple reevaluating their plan to phase out the Apple II, and eventual continuation of development of the older machine. As a result, later Apple II models incorporated some hardware, such as the Apple Scribe Printer, a thermal printer, and software technologies of the Apple III.

I have received a Commodore Amiga 500 to use as spare parts. I decided to restore because it’s a ASSY 312512 (Revision 3) with key-switch like IBM chiclet keyboards.
The cleaning took me a whole day but with a great satisfaction at the end of the work. The Commodore Amiga 500 works fine, the floppy drive reads very well and i have added a memory expansion (FAST RAM) of 512k.
