The conditions of this Commodore Dual Disk 8250 LP are really bad. The CBM 8250 LP is left for over 25 years in a dovecote.
The cleaning, repairing and restoration have taken a long time, but the result is more than acceptable.
The comparison (before / after):
Defects:
- Floppy Disk Drive completely dead.
- Main motherboard failure: Status LED green but with the Floppy Disk Drive LEDs (red) that blink 3 times and then repeat in loop.
- Directory displayed with extra chars.
Repair:
- Replaced all the electrolytic capacitors of the two Floppy Disk Drive.
- Replaced the IC RIOT MOS 901869-01 (Memory, I / O, Timer array)
- Replaced the IC RIOT MOS 6532 (RAM-I/O-Timer)

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.
The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).
There are two differents emulators:
- A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
- A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.

The ZOE Interface was developed by xAD^Nightfall and Damiano “Manosoft” Colombari.
The Zoe interface lets you connect the PAL Mattel Intellivision console to a TV/ monitor through the RGB signal of a SCART connector, dramatically increasing the quality of the video signal and bringing it to the highest possible quality: the original output is a modest RF/Antenna signal.
The interface is connected in place of the National LM1886 IC (TV Video Matrix DAC) to take the RGB and Sync signals and convert them for the SCART output.
This interface is not compatible with the NTSC (USA) Mattel Intellivision console because the NTSC version doesn’t use the LM1886 IC: the original video signal is never converted from RGB to Composite and then to RF (Antenna).
The assembled kit is available and you can buy it now from ebay (An installation service on the console will be available for less experienced users)
Download: Zoe Interface Installation Manual (English/Italian) (1829)
A new version of the manual is available here.

This gallery shows some stages of the repair of the Sinclair Spectrum 48k.
Defects found on the Sinclair Spectrum #1:
- Black Screen of Death/Garbage Screen.
Components replaced:
Defects found on the Sinclair Spectrum #2:
Components replaced:
- 5 x Electrolytic Capacitors 22uf / 16v
- 1 x SN94459 (LM 1889) Tv video Modulator IC with Chroma Reference Signal (Color)
Defects found on the Sinclair Spectrum #3:
Calibration:
- Calibration of Trimmer (VR2)
Defects found on the Sinclair Spectrum #4:
Components replaced:
- 1 x RAM TMS4532
- 1 x Transistor ZTX650
- Extra:
- Composite Video
- Conversion from Spectrum (Issue 2) To Spectrum +
Defects found on the Sinclair Spectrum #5:
- Garbage Screen and high absorption on the 12v line and 0v (ground) with explosion of the transistors ZTX-650 (651) and ZTX-213
Components replaced:
- 1 x Zener 5v1
- 12 x Electrolytic capacitors
- 3 x 4116 RAM (two of these in total short circuit between pin 8 and 16)
- 8 x OKI 3732 RAM
- 1 x Sinclair ROM
- 1 x 74HCT(LS)32
- 1 x Transistor ZTX-213
- 1 x Transistor ZTX-650
- Info:
- About the explosion of the transistors i have isolated the problem, are the ram (LOW).
The bad way used some years ago was cut the pin 8 of the all 4116 ram to isolate the bad one, in this case, i didn’t cut the pins of the ram, but i have cut the track of 12v which is part of all the 4116 ram, doing so, the transistor ZTX650(651) doesn’t explode.
At this point there is a short in one or more RAM between +12 and 0v. I have measured the absorption where i have cut the track and it absorbs too much.
I just have to unsolder the pin 8 of the 4116 ram and trying to isolate it for find which ram is short-circuited.
- …it was not over:
- When the repair is finished and i have replaced all OKI 3732 RAM with a new one, another IC has decided to die, a 74HC(LS)32. I have no words.
Defects found on the Sinclair Spectrum #6:
