Commodore 16 internal function ROM

For quite a while I had been wanting a member of the TED series. These are the computers from Commodore that employ the TED chip as their heart - the C16, the Plus/4 and their lesser known siblings, the C116, C264 and even C364.
What I really wanted was a Plus/4 because it just looks so good. A real cursor pad and better ergonomics than the C16. But an auction turned up and I got my hands on a untested C16 for an excellent price - it turned out to be fully functional (except a few broken traces on the keyboard matrix), and I upgraded it to 64 KiB and so on. What you'd usually do.
The TED computers share some common functions and are generally compatible with each other. After upgrading my C16 I had been wondering whether it would be possible to add internal function ROMs to the it. Its sibling, the Commodore Plus/4, ships with internal functions ROMs that provide the productivity software suite, but other, more interesting, options are also available. One thing they share is allowing for external function ROMs, on the Plus/4 you can have 32 KiB of internal ROMs (divided into 16 KiB "high" and "low") and the same externally in the cartridge port. The Commodore 16 only allows the external ROMs out of the box.

I wanted to find out if it would be possible to add something internally to the Commodore 16 as well.


Run VICE on your PocketCHIP

So you received your new PocketCHIP after waiting anxiously for the past months, and you're itching to put it to good use. And what could be better than a spot of Bruce Lee? Let's get the VICE emulator up and running.

The PocketCHIP runs Debian Linux, so getting VICE installed couldn't really be easier.

You will need to be in the console app for the rest of this guide. You will also need to be connected to a working WiFi accesspoint.

First off we need to update the database of available packages. Remember that the default password is "chip", you will need this for sudo.


Modifying a Datassette for audio in

It's possible to load tape games into a Commodore 64 using a mobile phone or mp3 players. You can either convert the programs into audio files or you can use a dedicated player on a mobile phone.

I have used the Android program, TapDancer, which does a fair job. It's not the greatest UI and preparing a tape file for playback is pretty slow, but on the plus side, it does have built in C64 tape turbos.
