So I received my PS/2 model 70 today. Unfortunately, as always seems to be the case, they are not quite in the condition shown in the eBay pics.

The PC, Monitor, KB, and mouse are all pretty dirty and discolored.

I have done some research, and it seem like I have 2 options:

1) I can whip up some RetrObrite, and try to get the color restored that way

2) I can buy some spray paint and go that route.

Which should I do? If it is the spray paint route, which brand/finish?

Also, I know that they are not the original component for this PC, but I was thinking about simply buying a new IBM Keyboard and mouse. Would the ones below work with this PC and which would be the correct color match?

(this one says french/english... does that mean they have french character sets/text on them?)

Mice

And then I was thinking.... what if I modernized it a bit, and painted the PC case and monitor shell black?

Would this black KB and mouse work?

Hi,

Congrats on the new system. There is plenty of info on RetroBright here on the forums but the biggest thing you need to know is that it is NOT permanent. The long term results are coming in and people are seeing the discolorations re-occurring. Spray can is much more effective but matching, color, texture, etc. is much harder to do.

As for KB and mouse any PS/2 KB and mouse combo should work for you on that system. Or you can just buy the "original" parts. I.E. a 139401 KB and IBM PS/2 mouse. The mice are found NIB relatively easily and KB can be had for $30-$50 with some patience.

Just clean it up the best you can using Simple Green or some other good quality cleaner. Some people prefer to have the "vintage" or aged look. My model 50z uses the same chassis and it was grimey to. Used some Goo Gone for the sticker residue and simple green and it turmed out quite nice. A few blemishes here and there but not a big deal. As for the keyboard use some Q-Tip's and get in between the keys using a a good cleaner all over the rest of the keyboard. I ususally clean the keytops with iso alcohol you don't know whose fingers have been on that keyboard same with mouse buttons as well. As for the Mouse, remove the ball and clean the rollers inside. Just wipe it all down real good and then remove any cleaner residue.

It's all up to you just be advised that retrobrite use's hydrogen peroxide. Get that in your eyes and your permantly blinded! It disolves the cornea! So if you do the retrobright way please use a face sheild. Obviously use extreme caution!!!! I won't touch the stuff at all.

So clean it up real good! Or take the lid to an ACE hardware store or Lowes and try to match the paint color. I found the perfect color for the PC/XT at Ace it was some off grey color.

I have this bottle of de-icer. I have no idea where I got it from and it only states that it's ethanol based.
One really weird thing it does is if you spray it on a yellowed plastic (examples were a DEC Rainbow and an LA-120) it will almost immediately reduce the yellowing.

Take the keyboard and mouse apart and wash the plastics with an oxy based dishwashing liquid and plastic dish scrubber (basically you don't want to scratch anything). You will be surprised how well they will clean up. Do the same with the computer case. pretty much anything you buy out of the box that is that old will have some discoloration, I wouldn't worry too much about it unless the discoloration is uneven (looks very noticeable). Even if want to paint the stuff you still have to clean it.

But does it last or fade back to yellow like Retrobright?

Well, the PC and monitor are actually in really good shape. No Yellowing, just needs a good cleaning. I have some followup questions.

It came with the original clunky mouse. Will keep that, but looking for something with a scroll wheel. Would his work?

Also, the coiled KB cable is dirty, and looks like it will be very difficult to clean. Any tips? If it were straight it would be a breeze. I know it is an extension, but would this cable work as a replacement?

Any PS/2 keyboard will work. I use a USB to PS/2 adapter on my Model 50z with no problems. You could do the same.

NeXT: Springbok and I are both in Central Florida where it rarely if ever snows or freezes. Chances of finding that stuff around here are like forgive
the pun. A snowballs chance in Florida!

Thanks Chrome. What about USB mice? Can you use a modern mouse with a USB adapter?

PS: I see you are in CFL... I am in Orlando, so we are probably a snowball throw away from each other.

I think that is what I was hinting at. I use a microsoft USB mouse with a green usb to PS/2 adapter and it works fine. So yes you can use a modern mouse.
Oh check your PM.

Snowball wouldn't make it 5 feet before it melted on days like today. High of 94. Sorry off topic

A wheel mouse isn't going to be too useful with period operating systems unless a driver was written to support it. It won't work in DOS that I know of. I think Intellipoint for Windows 3.1x supports it.

Sorry, meant to ask if an OPTICAL mouse would work. Don't know if you would need a special driver for that, and if so, if there is one available for Windows 3.1

Yes an optical mouse works fine. No special drivers it's all invisible to Windows 3.1 and also the wheel won't work unless you can find a Win 3.x driver for it.
