My Commodore 64 chip testing board

I got a dead C64 off eBay cheap, I mean really cheap. the seller said it was dead and the repair technician said it was not worth fixing. I took a chance and bought it thinking I could salvage some chips. When I got it and looked at it in the magnifying glass I saw something that was interesting, the fuse clips where bent out and not making contact. I thought, nah, that can't be it.. Yep, that was it, the board fired up although needing more repair. after some chips checking the PLA was bad, I replaced it and bam. Working c64. The seller packaged this c64 terribly and the case was broken the keyboard is missing keys ( I did know that though before buying)

So now I have this working C64 board with no case and no keyboard, so I decided to make it a chip testing board. I socketed all the chips to repair other C64's, I can test the chips and look for the band ones.

Here is the pic. if you want one, let me know. I can make them, but they are not cheap, I takes me hours to desolder all of the chips and replace them with sockets.

$200 if you send me your board
$300 with no chips. One in stock
$400 with all chips and working. One in stock

How to check your router for Vulnerabilities using RouterSploit



I am sure you have see the messages from the FBI and NSA about updating the firmware in your router and rebooting it. I would also like to add that you should also change the default administration password as well and disable any remote administration. The last part is up to you.

I also want to know after doing this if my router has any vulnerabilities that I should know about. To do this I am going to use Router Sploit.

I am using Ubuntu 18.04 but you can use Mac OS too, many ways exist to get a VM of Ubuntu to do this so I will let you find that out. this tutorial is just how to get Router Sploit going on your Linux system.

Ubuntu 18.04 & 17.10

Sudo add-apt-repository universe
Sudo apt-get install git python3-pip
git clone https://www.github.com/threat9/routersploit

change directory to /home/routersploit or for kali /root/routerspliot

sudo python3 -m pip install -r requirements.txt

sudo python3 rsf.py



at the ref prompt type in

use scanners/autopwn
set target 192.168.1.1 <- this is the most common gateway but make sure to use yours if different

run

You will now see that either your router has no vulnerabilities or it does. If it does and you want to run an exploit on it to see what it returns (what a bad actor would do). do the following.

in this example rsf returned 
-exploits/cameras/brickcom/users_cgi_cred_disclosure

type at the prompt

use - exploits/cameras/brickcom/users_cgi_cred_disclosure
          ^    ^       ^          ^
          copy and past from the top......

set target 192.168.1.1

check

          if check returns "Target is vulnerable", you confirmed it

now exploit it

type run

now review the output of the exploit

you may not like what you see. but if it's bad, patch your system or upgrade.

Hope this help

Commodore 64 black screen at boot up repair

Hello everyone

Today I had a Commodore 64 on the bench with the black screen at boot problem, I did a quick video on how I fixed it. I suspect that most these problems are the cause of the power supply, it get's old and over voltages the computer and cooks a chip or two. could have even been a static electricity to the computer.  I hope you find this interesting and or helpful if you want to fix your commodore 64.

Enable Windows 10 Ultimate Performance mode

you can do this after you get the 1803 update

open powershell in administrators mode
type in this command
powercfg -dublicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
now go to Power Option and unhid additional plans
you should now see Ultimate Performance

This may or may not make any difference but if you have a desktop, this may give you a few more FPS...

Enjoy
