Title: PC2086 - Keylock
Post by: chinnyhill10 on 12:59, 19 February 16
The PC2086 has arrived. It displays the key lock fault that you usually just hotwire across the switch. Except the switch is missing! Someone has got here before me.


Anyone recognise these two wires? Are they the key lock so if I short them all would be well? I have the official keyboard but no mouse (but presumably lack of mouse won't stop machine booting).

Absolutely no idea what the previous owners have been up to inside this case.

Was there meant to be a picture that we can see in that post?

Yep. I can see it. Can't you?

No, there's no picture in your post on my screen.

Bryce.

Edit: First I'd check where those wires are going to. Then test them while the machine is running to see what voltages are on them. You could short them very quickly while the PC is running. If the PC doesn't reset, then short them again and see if the keys work.

Edit 2: @Gryzor (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1) In IE11 I can see the picture in chinnys first post. In FireFox 44.02 it's not there.

@ chinnyhill10 (http://www.cpcwiki.eu/forum/profile/?u=984) Have you compared to pictures of unmolested machines? If you can see the same colour wires running between the switch and the motherboard, that would be a good sign that your wires are the key switch wires.

If you have a 100 ohm to 330 ohm resistor, try connecting it between the two screw terminals / wires.

Can't find a service manual for this one unlike the earlier PC's. Lots of resisters around so can try one.

Setup I used. Windows 8.1. 64-bit.
adblock was installed.

I can also see it on 64-bit linux, firefox.

Ok, even weirder. I am now on a completely different PC, different ISP, different connection setup, no firwalls, FireFox 44.02 again, no adblockers and I still can't see the picture. Only when I run IE11 ???

Java ? Javascript ?
Title: Re: PC2086 - Keylock
Post by: Bryce on 22:46, 19 February 16
Java isn't installed on either computer, but wouldn't that cause it to not display on IE11 too? And why would I need Java just to display a static picture in a Forum? Up to now I could see all other pictures in the forum.

So it may be a "mixed content" problem ?

Disconnected the bridged connector at the header and suddenly it all worked. Then a tiny bit of metal fell out of the connector. Someone had bridged it with a staple!


Now confused as web sources say the bridged state is unlocked but mine isn't bridged. Ah well, who cares!


Machine is in a right state inside. Needs a good clean. Think the internal hard disk is dead (was unplugged). Dunno how to activate it to see if it is alive or not.


Heavy rust on PSU casing. Unsure what to do about it. Looks like a CMOS battery has leaked onto it.


Will give it an initial cleanup and will tackle rust and the rest later!

What an effort for such an old PC ...

Wish I never sold my first PC ... 486/33 , 4MB RAM, 106 MB HD, 1 MB ET4000 WIN 3.1 AND 14" targa 1499 NL that was just AWESOME 1992

Slightly missing the point.  :D


Cleaned up the rust with sandpaper. Not as deep as feared but was still hard work.


Also took out the hard drive and the weird controller. HD hardly likely to work (and 30 meg is useless anyway) and I can repurpose the space inside the case for an HxC or other floppy emulator to work as a B drive.


Working well. Just cleaning her up now!

Nice work. I had a 3086 back in the time... Quite the same as yours. Funny to have a great video card (Paradise VGA) with such a crap processor...

Opera, Chrome, IE and FF all show the picture on my work PC, even through our #@!*^% firewall. On my mobile I tried it in Flynx (both mobile and web versions), Chrome and FF - again it works every time...

No, that can't be it either. I can see the picture on the same computer and connection if I use IE, but I can't see it in FF on my PC at home which is using a different connection. So it must be something that I have installed on both PCs that only effects FF. But I haven't found anything yet. I thought it might have been ABP (Ad Blocker Plus), which is on both and only on FF, but turning that off didn't make the picture appear.

Ok, something happened that it has got worse. In the GND for Dummies thread I can't see the attachment, but in IE I also don't see it any more, it just shows a small black box with an X in it.

Putting that URL (less the "large" statement) directly into the address field I can see the picture.

The server is fine. Monitored 24/7 at this point, and i'm online for the past hour or so without noticing a single issue :p


CPU load:
[attachimg=1]
(note that the top line is only 30% of the CPU)


DB load:
[attachimg=2]


So, really not sure what your issue is :D

ABP in use on FF on my PC and no problem with displaying the picture in the first post.

The picture in AMSDOS's second post does not work for me either. I'm sure that the Peter Vis (http://www.petervis.com) web site does not allow direct linking to pictures (as in it blocks them).

Yeah! Finally sorted the problem out. No idea what the problem was, but I completely de-installed FF, then went in and deleted all the files and directories it had left over (47MB worth!!) and re-installed. Now the pictures are showing up.
Possibly due to always updating and never doing clean installs. I'll do that tonight at home too :)

No. Your "messing with the server" (or whatever it was) was causing "no access, please try again later" type messages. The picture problem was my FF.

Dear all, I found this thread which is relevant for my issue, so I continue here.

Today I wanted to restart my old 2086 but I got the “keylock” beeping error at boot.
Last time I played with my 2086 I guess it was around 5 years ago and it worked well.
I followed suggestion in the previous posts: I disconnected the keylock connector and Inalso tried to short circuit the two keylock wires, but no results. The keyboard apparently works: in fact before the error, it is possible to activate/deactivate caps lock and block num. Then when it starts beeping, block num starts blinking.
What can I try to do ?

Thanks !!
