which 1084s ?

[ulkealan]

Hi,

Many years ago I had a commodore 1084s monitor with my A500..
I really was very satisfied with that monitor. If I am not wrong, mine was 1084s-P.....
Now, for some time, I am looking for the same one but couldn't succeeded. I bought 1084s-d2 last year, but don't like it. I don't know the reason but I simply don't like it.

Anyway, I found 1084st now made by likom but couldn't decide.

So which one is better ? Which one do you prefer?

Thanks,
Tolga

In what way don't you like it exactly? Aesthetics or performance? I always thought 1084's were mostly the same internally. The only difference in performance I saw was with my Phillips CM8833-II which was sensational.

hahahhahaha what an interesting thread.

1084p is a philips,1084D is a deawoo,D2 is a deawoo.
1084s-p1 is a philips,its a 8833-II internally

1084 has about five main variants there all different internally.with slightly different configs on the boards for different inputs on each variant

you can normally find out what chassis it uses by the suffix code on the back of the monitor and the chassis config,it tells you who made it and what inputs it accepts and what region its for mainly.most info can be got simply by looking at the back connectors and mains voltages,the rest from the last two digits after the model number will tell the chassis in it and its config.
then theres the subject of tubes used in them...we could go on all day with that alone in combination with the chassis

I suppose in theroy, differences in analoge boards, components and circuitry in general could have differences on the display even if they are the same tube.

@all
let's make it more clear
because 1084s-P was my first and only amiga monitor, I loved it too much. I had so many memories with it. The reason why I had started to buy Amiga again at an age of 39 is only because to buy my commodores back again......
Still I couldn't find time to play / deal with my commodore collection, but I will do some day and will make a room only for my commodore hobby....

If we come to my question again, maybe I am wrong, the seller at 1980's sold me the 1084s-p only because it is stereo and because of its flat screen. To be honest, maybe there were only 1084s-p in Turkey. Anyway, maybe because of its shape, I really like it...

Last year, I bought a 1084s-d2 from a seller from Germany. He sold it to me as "like new" but as always, it is not "like new" so I am looking for a really "like new" one...

My main question is about the difference between 1084s-p and 1084st ? I found some info from web and it says;
1084s-p:
- Stereo analog/digital RGB and Y/C video monitor
- analog RGB
digital RGBi
PAL separate
PAL composite
- female 6-pin DIN connector
female 8-pin DIN connector
2x RCA connector
- "600 lines in centre"
- Philips CM8500

and for the 1084st:
- Stereo analog RGB and Y/C video monitor
- analog RGB
PAL separate
PAL composite
- female 9-pin D-sub (DE9F) connector
2x RCA connector
- 640x512 (interlaced)
- Likom #1b (1994 (after Commodore's bankruptcy) )

So would someone please translate these info in a more easy way ?
Basically, will there be any difference if I use this for my A500, A600, A1200 and C64, C128 ?

Thanks for answers

Uhm. Google is your friend. Here is the full list of Commodore monitors. They all are subtly different, but surprisingly enough 1084S-D1 and 1084S-P1 are quite similar (some say D1 is better, some say P1 is better - depends on what you want to do) while 1084S-D2 and 1084S-P2 are significantly different (but, again, very similar to each other).

Main difference: C128 does not work in 80-column mode with 1084S-D2/1084S-P2! They just lack the required electornics! 1084ST is more-or-less like 1084S-D2/1084S-P2 (functionality-wise), but in differently-shaped case.

Note: some monitors have 6-pin DIN connector and 8-pin DIN connector (for separate analog/digital RGB input) and some have 9-pin D-sub connector and a knob. Surprisingly enough that difference is superficial: you just need different cables. Later models, as said above, just don't support digital input (yes, in that particular case digital is older and less "progressive") and simple passive cable wouldn't fix the issue.

Thanks khimru

Last 2 questions;
1 ) May I use 1084s-p or 1084st with my C128 and A1200 ?
2 ) what is the difference between analog RGB and digital RGBi ?

You could use both except if you want to use 80-column mode. Then 1084-P (if that's 1084-P, not 1084-P2!) will work, while 1084ST wouldn't.

2 ) what is the difference between analog RGB and digital RGBi ?

Analog RGB: one wire per color (Red, Green, or Blue). Intensity is determined by the signal level. Billions of colors are possible in theory, but quality of connectors, cable and so on matter. A lot.
Digital RGBI: four wires (not three!), each one is either 0 or 1. Red, Green, Blue plus Intensity. Colors are crisp, clear, but there are only 16 of them at most. Because four wires are used instead of three that scheme is completely incompatible with previous scheme (could be converted with some transistors and diodes, but not with just a passive wires!).

Older models of 1084 supported both digital and analogue RGB (but had many different connectors depending on the model: older monitors carry two (one for analogue RGB, one for digital RGBI) newer monitors carry another, different one, plus RGB/RGBI switch), the very latests ones dropped support for digital mode. 40-column mode is supported by C128 with a composite output and don't need RGBI connection to be usable, 80-column mode require digital RGBI, it just wouldn't work with composite (aka "half-century old TV") connector (it could work in monochrome, but you don't use 1084 to just do a monochrome). Amiga also supports composite output but also supports analogue RGB (which is better than composite in most cases!)...

1084st wont work with a c128 in 80 colomn mode,i cant see a ttl input


oops someonwe already answered this question in detail.....

 

[ulkealan]

Questions answered,
problem solved

will mods close this thread ?
Thanks,

Anyone ever mod a mono 1084 to stereo?
