no dip switch under the power as theres no mobo there but there is a dip switch kinda near the rams... but i have a feeling i shouldn't poke around with it without knowing what it does, it can also be seen on picture, it's on the right side towards the edge of the mobo.

What is under the drive bay at the top left of the picture? Is the Mobo really irregularly shaped as it appears? What are the red things underneath the drive controller at the top of the board? I can't say I am being too helpful anymore but thank you for your replies.

[Elvicat]

under the drive bay is the mobo and you can see the power unit down on the left side and you should be able to see that the mobo goes beside it, and yeah the mobo isn't squarish like todays mobos, red thing!? can't say i see any red thing there, maybe your seeing the mobo, even if it looks odd the mobo is 1 whole thing but just under the controller it's shape changes abit

[bilbous]

This thing, between the drive bay and the top of the drive controller. Probably just a capacitor or something.

i don't know what thouse are called but they are apart of the mobo and they arn't switches, from what i've seen these can be found on many older hd's to, they look like this, long and small with multiple legs

well i've finnaly put it back together and the info i gathered from it i've placed in a list of computers of all sorts (still to be finnished)
havn't gotten the 1mb memory activated yet if it's even possible but i've had some 286 with more than 640k ram and that's no extra memory card, maybe i'll figure it out sometime or someone get's an idea and posts it here

okay... i've started up on this oldie once more and now i'm trying to figure out it's age but not really found anything usefull as the 84 number on it's back seems to be something else.
however i found these numbers on the mobo itself
PC/900-2 PB85065-(1)-2Fi
S/N:A0407956-E
003584

if anyone got an idea please post, i know from past experiance that this one is hard to get any info from

You might try checking the bios version, the copyright notice will give you an idea. It should be one of the first things that gets displayed on the screen if anything is. You could maybe search that in a repair manual...

[Elvicat]

it's a old award bios but editoed by commodore something like version 3.0 but thats about it, there's almost no info at all there and very litle edit options, i've prolly said something like this earlier in this thread

[Prolix]

No I meant the on screen info that shows before the post completes not what you get when you enter the bios. If you hit the pause button when there is just a little text on the screen you should be able to take down the exact text. Maybe not though. other than that I can't offer much help.

theres no post screen on this comp just a litle info when it comes to life and thats the bios version and copyright stuff of award and commodore

[Prolix]

That is what I am talking about, perhaps it is more minimal than I expect but if there is some kind of code with the copyright it could be significant. Basically anything like an alphanumeric. They were used to give information about the hardware the bios was designed for back in the days when none of that was printed on the mb. Still it may be a blind alley even if it is as I suggested..

[Elvicat]

no there isn't anything else when it boots no extra numbers just the bios version number and copyright, the only nunmbers i found where on the mobo itself but no date atleast not yet
