I have repaired the Commodore Amiga 2000 with a Black Screen for a dear friend.
Defect:
Diagnosis:
- The Battery Acid has corroded some pcb tracks (not visible to the naked eye) connected to the pin of the resistor packs RP900.
Repair:
- I have made three small bridges between the points on the solder side of the pcb and the problem was fixed in a short time.
I have repaired the Sharp Twin Famicom AN-500R for a dear friend.
Sharp Twin Famicom AN-500R Repair.
Defects:
- Black screen.
- Distorted sound.
Fix:
- Cold solder joints.
- Cleaning the volume slider on the second Joypad.
The microphone is mixed into the output signal, if the contacts of the volume slider are dirty you hear a background noise which disturbs the in game audio.

The Commodore 3040 it’s a dual drive 5¼” floppy disk subsystem for Commodore International computers. It uses a wide case form, and uses the IEEE-488 interface common to Commodore PET/CBM computers.
These drive models use a similar single density, single side floppy data storage format to that used by the Commodore 1541 drive, but with a slightly different data marker indicating which model originally formatted the disk. The low-level disk format was similar enough to allow reading between models, but different enough that one series of drive models could not reliably write to disks formatted with one of the other model series.

The Macintosh Classic is a personal computer manufactured by Apple Inc.. Introduced on October 15, 1990, it was the first Apple Macintosh to sell for less than US$1,000. Production of the Classic was prompted by the success of the Macintosh Plus and the Macintosh SE. The system specifications of the Classic were very similar to its predecessors, with the same 9-inch (23 cm) monochrome CRT display, 512×342 pixel resolution, and 4 megabyte (MB) memory limit of the older Macintosh computers.
Apple’s decision to not update the Classic with newer technology such as a 68010 CPU, higher RAM capacity or color display ensured compatibility with the Mac’s by-then healthy software base as well as enabled it to fit the lower price Apple intended for it. Nevertheless, the Classic featured several improvements over the aging Macintosh Plus, which it replaced as Apple’s low-end Mac computer. It was up to 25 percent faster than the Plus and included an Apple SuperDrive 3.5-inch (9 cm) floppy disk drive as standard.
The Classic was an adaptation of Jerry Manock’s and Terry Oyama’s 1984 Macintosh 128K industrial design, as had been the earlier Macintosh SE. Apple released two versions that ranged in price from $1,000 to $1,500. Reviewer reactions were mixed; most focused on the slow processor performance and lack of expansion slots. The consensus was that the Classic was only useful for word processing, spreadsheets and databases. The price and the availability of education software led to the Classic’s popularity in education. It was sold alongside the more powerful Macintosh Classic II in 1991 until its discontinuation the next year.

Repair Apple II EuroPlus.
This computer has taken a lot of moisture and temperature changes, it can be seen because the connectors (Apple BUS) have dried up and the plastic tends to break. In addition, some pins of the ICs are rusty, fortunately few.
The main problem of this computer, as well the removal of the usual filter capacitor inside the power supply, was that don’t accepts some basic commands (see photo)
The problem was caused by the malfunction of the PROM 341-0014. (E8)
The owner will have to decide whether to purchase the original PROM (current price €13,90 + Shipping) or use a horrible adapter to insert an EPROM 27C16 (2716) in place of a PROM.
This adapter in addition to changing the aesthetics of the original motherboard brings with it some problems.
- 16k language card don’t work.
- Long cards which extend to the part of the circuit board cannot be used.
