That's because you can't write to a CD. Sorry, that just can't be done.

As far as I can tell, the software did not complain.
Maybe the chances are favorable.

It is easy enough to source some 1084S parts.

Nice, the amazing world of "old stock" on ebay.

As Castellen mentions, make sure it's an exact number match.

I'd agree with the suggestions above from Plaz.

It is easy enough to source some 1084S parts.  4-5 years ago I replaced the failed line output transformer in my workshop test monitor with a new one from Ebay.  The monitor gets a lot of use and the replacement part is still working perfectly.  A quick note for anyone looking to replace a line output transformer, there's two main variants of the 1084S, you need to select the correct part:
https://www.ebay.com/itm/323271046225
https://www.ebay.com/itm/323881872931

The Commodore monitors are not significantly different to a CRT television, so providing you can find someone local familiar with repairing CRT TVs, then it's probably realistic to repair the 1084S.

It may be relevant that some months ago I force-ejected
a disk from my internal CD-ROM's drive by sticking a pin
in the pinhole.

Anyway, my problem now is that the drive opens and closes
repeatedly during bootup of my OS 3.9 A4000 and no disks
are recognized.

Anyone have any idea on how to fix this

The VIC-20 user's manual included specs for all the port pin-outs, and the reference guide came with the full schematics of the computer itself.
I suppose that one could argue that with the complexity of modern computers, this would not be feasible, but it shows how things have changed.

The Commodore 8-bit line (and to some extent the Amiga) were made to be tinkered with and hacked. The VIC-20 was in a way the Arduino of its day.

Depends on the type of the error.
If it is a checksum error the tool might ignore it or let you decide to ignore.
If the disk has serious reading fails then the ADF creator will stop reading or try to skip the faulty block. In both cases the resulting ADF is incomplete.

Amiga Software Issues and Discussion / ADF Question

If I use an ADF creator software to make an adf of a floppy disk will it copy errors?

the cost will be high or even prohibitive

Yes.  :(

"Flyback transformer" failure was a common problem with certain versions of the 1084 and 1084s models.
But it's been a couple of decades since replacement flybacks were available.

Senario 1 ..the flyback leaks or shorts completely, which then kills other components in the high voltage section and the power supply.
The 1080's were work horses and also many of the earlier 1084's.
However in Commodore's last years I found the later model 1084 and 1084s to be very cheaply made with higher failure rates.
(and don't even get me started on their multisync 1950 and 1960's :P)


This is a quick test for a technician that might cost a $2 fuse.
With power removed, open the monitor and blowout ever bit of dust. Especially around and under the flyback and also the back of the tube.
Inspect the circuit board for any burns or very dark colors. If any damage is seen... abort.
If the circuit board looks clean, replace the fuse, re-assemble, and power up.
Three possible outcomes...
1 - Turns on (Yay! Until it goes out again some day)
2 - Pop! (bad and expensive components have blown the fuse again)
3 - Power button light flashes. (power supply and other components are probably ok, but the flyback has died)

If a repair is needed, it would be expensive and maybe not even possible due to lack of available parts.
I'd look at some of the other options available these days that have a better looking picture.

Thank you very much for the answers :)

I'll search now in those high voltage terms, good advice!

I hope to find someone soon. If not local, at least at a reasonable driving distance.

Regards,
Efrén
