i just got in today a A500 Video RGB to 6Pin RGB cable i can see it in color but its not Syncing like Vhold or H-hold needs changing but the 1084 doesnt have any VC/H-hold knobs for adjusting :/

any way to correct this ? as i hope i didnt just waste 24$.



Hmmm - the standard way to connect an A500 to an 1082 or 1084 monitor here in Germany was via a cable with a 23 pin D-SUB plug on the one end and with an EuroSCART plug on the other end.

Never heard of the '6Pin RGB cable' you mention, but maybe such cables were used e.g. in the U.S. or other exotic countries...
:biglaugh: :p

LOL.
...
Newer, less crappy 1084 models connect via a 23-to-9 pin D-sub connector.  Viva la standardization!
 :lol:



Well, I even have an older model since 1989: the CBM 1081, which I altered to stereo sound myself.
Still in working condition...
All the best,

All 1084 models suffer from crappy power-switches.
I recently bought some replacement switches but they seemed even lower quality than what C= used...

If "modern style" means power-switch at the back - no thanks, that's annoying to me :)



My A1200's monitor suffers from the same issue.
I overrode the switch and use a multiway connector with switch to switch my euqipment on or off instead.

Never used the monitor built-in speaker, so don't really care if its mono or stereo. It sounds terrible either way!



You are of course right regarding the sound quality.

But it was a good thing to have a stereo monitor when I visited my relatives in former East Germany back in early 1989, before the fall of the 'iron curtain'.
I took my A500 and the modified monitor with me and demonstrated the capabilities of an Amiga to all my cousins - and the stereo sound certainly was one of it's capabilities...
3 of them bought an Amiga after the fall of the wall...

Only very few East Germans had stereo equipments before the fall of the wall - most were on mono - even the discotheques.

I remember one popular discotheque in Magdeburg (Cafe Impro), where they used a 'manual lighting console' instead. That was a guy with a wooden plank and lots of pushbutton switches (connected to the different coloured lamps with lots of cables) on it, which he pushed with the beat of the music...

So I bought an assembly kit for an 'electronic 3-channel lighting console' for roughly 28 DM, put it together and donated it to my cousin, who was a DJ at the aforementioned Disco back then. That made him the first DJ with a 'electronic 3-channel lighting console' in Magdeburg...
:hammer:

I did try working with an LCD for the Amiga but quickly moved back to CRT, there's just no comparison in demos & games, IMO.
I'm currently using a 19" Viewsonic CRT which can handle 50Hz,



Able to handle 50Hz mains frequency or able to handle 50Hz display refresh rate?

picture looks great & there's zero motion-blur, which is something I noticed on all LCDs I tried.



That may depend on the phosphorous coating in the CRT. I have very well had CRT-TVs with a very high afterglow time and a lot of motion blur by that...

On computer screens I have not experienced 'motion blur', as I rarely use them for watching videos...

Never seen CRTs with high-decay phosphors, although I know they existed.
It was just a silly idea really, can't imagine it being useful for TV watching or computer use which involves lots of motion, like games.



Not sure what you mean with "high-decay phosphors" (maybe a language problem) - I was talking about the afterglow of the phosphorous coating in the CRT. I remember early color TV sets with an enormous afterglow. Best noticeable when e.g. watching the night phase of the "24h of LeMans" race, where the head lights looked like long flames because of this afterglow effect...
All the best,

*cough cough* Productivity software *cough cough*

Not everyone uses their computer just for watching TV and playing games, lol.  :lol:
...



1+!
:biglaugh:
That's why I never really cared for the afterglow of computer monitors...

But afterglow on a TV screen is a completely different story...
