CPC EXTENDED
Computer LCD connected with RGB / CGA card and 5Volts powersupply. CPC
Extended connected with 5/12Volts computer power supply. However, due the
internal faillure of the powersupply 5/12Volts, 12 Volts came on the 5
Volts input of the CPC Extended. No working LCD screen anymore and that
explained it. RGB / CGA card itself works. Could set the LCD monitor properly
...
Noticed the smell of 12Volts faillure to late
so ... ! @ # $% ^ & * ().
That will be the complete repair of computer
epromkaart, sound card, disk drive roller ass, 64Kb memory, etc. Lucky
I got of nearly all the cards, except the epromcard. The parts to repair
the Superplus Epromboard,
I bought at Radio ERNST
in Hoorn. |

The eproms of the
Super Romplus
epromcard, who were on it, tested
with a 6128 and a KDS epromcard
were allright,
except for the
A.R.C.S operating eprom.
The eprom software
has been
downloaded from the Internet and
burned with an EROMBURNER
on a DOS computer. The next step
is to repair the
Super Romplus
Epromcard and connect it
to the
repaired CPC EXTENDED, so it's
running again... |

| The Super
Romplus Epromcard stopped working.
Wire broken from the solder point on the switch,
in taking the card more times by hand
viewing the parts.
Wire (Yellow) soldered again.
Epromcard partially working again. Can be switched
on/off again. Next step is replacing of the
diodes,
resistors nnd control chips. |

| Replacing the three diodes of the Super
Romplus Epromboard. Testing the card,
works without the Eproms and can be switched on/off. But with the A.R.C.S
operating eprom the card won't work yet... |

Repaired Britannia
Super Romplus card not working!
After that the print solder attachment has
been controlled and possible repaired.
Did'nt work at all. No screen. Planning the
card to bring to a professional for repair. |

| On 02-02-18 the Brittannia
Super Romplus Card brought for
repair to Mofix in Berkhout. And the whole story of the failed repair by
Symtronics. Also partly my fault to give the order to repair, to place
the new chips in sockets. One of the things you never must do....
Mofix did solder the chips with SMD technology
directly on the PCB and repaired other print solder. An elco also had to
been renewed.
After mounting the card into the CPC computer
case, the screen was right and so all mounted roms... |
