Roxbury Software

I have finally put CGTerm 2.0 on GitHub. After putting it up, I decided to run the binary that I had compiled for Mac a few years ago. Even after forcibly adding the SDL framework, all I could get was a blank canvas. This was reported the some time ago. I was hoping that it was simply a matter of needing to give the SDL framework permissions to operate out of the Framework directory. No such luck

I then decided that I should recompile it with Xcode. Maybe be recompiling, I could finally add the SDL library in with the package and not need an extra step. That would also allow me to work on adding the menu in to work natively on the Mac.

After probably an hour, and ringing the bell with my blood pressure, I gave up. I kept running into build issues that not only didn’t make sense to me, but that Google wasn’t helpful enough. I have limited access to a Mac that can run current Xcode. So while the code is out there, I am going to pivot and concentrate on both a Python version that will be much easier to compile and run cross platform (I hope) and a web based version so that I can finally BBS from my iPad.

I was hopping to someday bring a native C64 terminal program to iOS. Instead, I would rather have one working that I can use from anywhere and a version of my beloved Color64 running on a server. I might be crazy (OK, no might about it. I am certifiable.) but I want to run a real BBS again. I don’t have bare metal, and I haven’t quite figured out how to interface VICE with Telnet acting like a 1670 modem.

Instead, I want to run a service on PHP that will open the D64 disk and interpret the BASIC on the fly. It would also have an admin screen just like I was sitting down at my trusty Commodore waiting for another call. And how about being able to change configs and reboot the board on the fly? Like I said, I have a screw loose. So in the meantime, please enjoy the mods I did make and if you are able to compile and figure out the build bugs, please drop me a line so that I can add it to the GIT so that others can enjoy what few BBS’s are left on the internet.

Finally! I have been searching, and searching, and searching for a way to put an instance of the Color64 BBS online for some time now. My goal really was to be able to play Nuke Em again. Unfortunately after scouring the Internet I haven’t been able to find any mods for Color64. The only mods I have been able to find were for Image BBS. As I was never an Image BBS Sysop, they only interest me as to make a conversion of the game play.

Not finding any original mods didn’t dampen my desire to run a Color64 BBS again. Several people are doing that but they are either using a real Commodore 64 or a few of them are running them on an emulator hosted in Windows on winVICE. After trying to learn servers and web programming on the Windows environment years ago I gave up when I wasn’t able to pay Microsoft thousands of dollars or rent space on a web server that had enough permissions to actually learn something. I moved over to a Mac. Even Apple wanted to charge a premium for their web server though. Even if it wasn’t the thousands Microsoft wanted it was still too much considering Apple now wants you to upgrade every year and charge you for upgrading the web server software.

Enter Linux. Since most of the world is running on Linux with other part running Microsoft I figured I would give that a try. And I was very impressed with the capabilities. No longer did I need an expensive license to learn and host a website. Or to remotely manage my system at home. I could even run a trusty Commodore again.

But I digress. The moral of the story is that I found out how to get Color64 working VICE 2.4 with Ubuntu 12.04.4 Linux. The hack I put into place should work with winVICE on Windows as well as Mac. I haven’t tested on these platforms so don’t quote me. The hack involves replacing one file in the VICE source code and compiling.

Steps to running Color64:

1. Download tcpser. Tcpser serves as the bridge between VICE and the Internet. Once again, thank you Jim Brain for such a wonderful piece of software.

   sudo apt-get install tcpser

2. Next download the VICE source code. I used version 2.4 but with some modifications I am sure newer or older versions will work.

   http://sourceforge.net/projects/vice-emu/files/releases/vice-2.4.tar.gz/download

3. Expand the tarball to your Desktop or other directory.

   tar xf vice-2.4.tar.gz

4. Replace the rs232.c file in src/rs232drv/ with this modified version. I have commented out the one changed line and commented the inserted two functions and one variable. The changes were found from modified files at gcns.com.
5. Now when in the root of the VICE folder, Configure, Make, and install the VICE source code.

   ./configure
   
   make
   
   sudo make install

   Should you make any mistake or if you need to start over, you can uninstall by going to the same root of the folder in VICE and uninstalling VICE.

   sudo make uninstall

   There is another nice tutorial at the Ubuntu Forums that has helped in figuring out how to compile and install VICE.

   • When compiling on x86 I had no problems. When compiling on an x64 system I had to make a link in order for VICE to find the kernal. I am sure there is a configure option needed I just didn’t find it when I made this post. Until then if VICE complains that it can’t find the kernal use this command.

     ln -s /usr/local/lib64/vice/ /usr/local/lib/vice

6. Assuming the build and install process went well, we now need to invoke tcpser. Tcpser will act as the modem taking calls from the internet and putting them on the rs232 port in VICE. Open a terminal and invoke it with this command.

   tcpser -v 25232 -p 6400 -tSs  -l 7  -i "k0" -s 1200

   If you would like a little more information about tcpser and how this works with VICE, see this post.

7. Now we need to setup VICE to communicate with tcpser. I like to run VICE from a command window so I can watch the output and any errors that might come up. Either way we need to make the following changes to settings under the RS232 settings menu:
   • Turn on “Userport RS232 emulation”
   • Select “1200 baud” under “Userport RS232 baud rate”. (This can be changed in the middle of a session without a rest. Just remember that the speed tcpser reports can’t.)
   • Under “Userport RS232 device” select “Exec process”.
   • Under “Program name to exec…” type | nc localhost 25232 (Be sure to include the pipe “|” char at the begining. This command will send all input and output normally being sent to/from the VICE userport to “localhost” (if you have issues you can use the IP of the machine tcpser is running on. Normally localhost is an alias for 127.0.0.1) on port 25232. This is the IP and port of tcpser, our “virtual modem” interface.
8. Once we have VICE and tcpser setup we need to attach the BBS software to drive 8 and run setup. Make sure to uncheck “True drive emulation” under the “Drive settings” menu. That will speed up operation of the board a ton. You can get a copy of the Color64 disks here. All of the documentation I have read states that the author (Greg Pfountz) has released  the software into the public domain. Thank you Greg. It’s refreshing to see a copyright holder allow us to keep the software alive. The best way I know of to avoid the dreaded disk swap is to take all of the software on the D64 disks and put them in one D81. Right now the best way I know of is to use Style’s DirMaster. It only works on Windows. Hopefully in a little bit I will be able to update this to add an online tool I am working on that will let you do that and more. It will really be helpful for Sysops.
9. Next we need to run the setup. I suggest if you haven’t run Color64 before, or if you are like me and haven’t run it since before my kids were born, that you read the manual. The best manual I was able to find was here.
10. I won’t go into the settings much in this post, maybe in another post I will detail them. But for now the important changes are to these settings:
    • ‘Normal or Inverted hook’ = n
    • ‘User bit 32 = High Speed’ = y
    • ‘Use ‘AT’ modem commands’ = n (Very important. It appears that without this the BBS will always try to start at 300 baud. We want to run at 1200 baud. Either way, the BBS uses AT commands.)
11. Once setup is run it’s time to start it up. Settings will automatically load the board if you allow it. Once it’s setup we need to make a few ‘adjustments’ before it will accept calls hands free.
    • First we need to use a terminal to connect. See this post for more information on connecting from Telnet or CGTerm.
    • Watch the connection as you connect. You will see a screen like this. 
    • The garbage above Last Caller indicates the speed isn’t right. Switch the Userport RS232 baud rate to 300, you should see a ring message where the garbage was. Then you should see a ‘connect 1200’ message and your terminal will show junk. Now you change the Userport RS232 baud rate back to 1200 and you should be good to go.
    • If it still won’t connect at 300 or you didn’t start the BBS with 1200 you should reset everything. Close and reload tcpser. Then do a hard reset on VICE and load the BBS again.
12. The final step is to forward the 6400 (or whatever port you set -p to in step 6.) port on your router to the computer running tcpser.

Now tell the world that yet another Commodore BBS rises from the grave! You can start by going to Commodore BBS Listings or post an announcement on the Lemon64 forums. And by all means, please let me know to!!!

I miss running a BBS. That was back when you actually felt like YOU controlled the computer, not the other way around. These days even programmers don’t understand why the computer is acting up. It seems to take a village of IT people just to run a word processor.

That’s not how it always used to be. Back in the 90’s when I ran a BBS with Color64 on a Commodore 64 it only took one person to run the whole show. Not that it was a big show or very long running. Mine was canceled after about two years. And for good reason, it wasn’t very interesting. I didn’t have much software available to download and I wasn’t able to locate a ton of BBS ‘doors’ as they were called to play games on. Though I had a few.

My absolute favorite was called Nuke Em. In Nuke Em you played as a country and had to buy various parts of missiles and build a missile stockpile. Once you had a stock pile the only logical and fun thing to do is nuke your enemies. While that sounds more like real life now, back then it was fun. Like when as a boy I played ‘War’. Now days if my son asked to play ‘War’ I wouldn’t let him for fear that he would be shot by accident by the police. Not that police are wrong mind you, they just have a very tough job. And when they make mistakes, that’s all you hear about for a week on the news.

Anyways, back to the BBS, I also wasn’t able to generate much conversations on my board either. Considering that I maybe had 25 members that only wanted to download software I guess that shouldn’t have surprised me. But boy did I have grandiose dreams for that board. So I have been looking for a way to run Color64 again.

I don’t really have room or access to run a real C64. But even if I did it seems that the only instructions on the Internet today seem to require using a Windows system as the interface to the net. And since I am not made out of money I am using what I have available, an old PC I thought was dead running Linux. And I can’t seem to find ANYWHERE for step by step to run Color64 on VICE and get it to pick up the line when someone ‘calls’ in.

So I am doing the next best thing. Writing software to emulate the experience for me. Which is a HUGE undertaking. One of the issues is terminal emulation. Commodore computers used a customized keyboard to display text in a different way then other computers. This allowed them to have graphics in text. (See the homepage for an example.) Even HTML won’t do that as easily as the Commodore did.

Another issue with terminal emulation is nobody sits still. How much time do you spend in front of a laptop or desktop vs a phone or tablet? I spend a lot of time with a laptop but that’s at work. To really have fun I need to be able to access the BBS from a tablet or phone. That means emulate the experience of sitting behind my Commodore 64 in HTML so I can use my iPad to play those games. That’s a tough order. But one I might be able to accomplish by the time my kids emulate the XBox 360 to relive their youth like I am doing with the Atari 2600 now. So check back from time to time. Hopefully I will be able to post links to this project so everyone can experience those two Mountain Dew fueled years close to how I did. (Minus the heart problems I am sure all of that caffeine I drank will cause. And late nights spent fixing a door to work.)
