I finally managed to create a page on the kernal selector for the Commodore 16.
Last couple of months I was very busy repairing an Amiga 2000.
But last week I made some time to create a schematic of the circuit I created.
The circuit uses an Arduino Nano to listen to the reset line and reacts to it’s use.
this way you don’t need to drill a hole in the case, and the already existing reset button can be used to control multiple mods.
Last week I added several rom options to my Commodore 16.
So now my Commodore 16 is like a Plus/4 without RS-232 and user port.
The only thing left is a mod to select the rom option.
You can find the story here.
Yesterday I upgraded my Commodore 16 to 64 Kb of memory.
I’m still not sure if I can call my Commodore 16 now a Commodore 64 😛 .
Now it can run most Programs created for the Plus/4.
I wrote a little story on how to do this.
You can find it here.
This is first mod I did on my Commodore 16, I’m already planning to do more mods, like adding the 3-1 function rom of the Plus/4, Jiffy dos and a way to enable/disable and select the rom(s).
Today I finished Thimbleweed Park, a kickstarter from the guys that also created Maniac Mansion.
Thimbleweed Park is a nice game with a lot of hints to the old games of Lucasart.
If you liked Maniac Mansion and/or Zak McKrakken then you sure will like this game.
Yesterday I found an old project I made several years ago.
It’s a IECATA an ide interface for the commodore computers with the iec connector like the VIC20 and C64.
It’s based on a microprocessor and some memory.
The system lets you use the default commands to load and save files to an ide harddisk.
Last month I collected some new hardware.
I got a 1700 (c128 memory expansion, expanded to 512k), 1571 drive, Multi evolution 500 (a500 SCSI interface with some fast memory) and a surf squirrel (A1200 scsi interface).
And I picked up some old projects.
I will try to keep this site updated with the progress of those projects
A little update, Last 2 months I was busy adding pages to the data sheet part of the site.
And changed the way I wanted to control my commodore SX64 (and later on my compucase and Amiga).
My first Idea was to control the Kernal selections and drives id by a little FPGA, but it the FPGA I have didn’t like to have that much flipflops (memory for storing configuration).
So I had to go for a bigger FPGA or move to another way.
The other way presented it self to me 3 months ago, when I learned about the ESP8266 devices.
A ESP8266 Device is a cheap (2-3 Euro) module that contains a CPU, WIFI controller and webserver.
With some simple code, I turned it into an Access Point that has a website that is controlling the kernal selection and drive id.
The communication between the ESP8266 and the I/O chip (PCF8574) is done by I2C.
The circuit also contains a I2C EEPROM to store settings.
Last night I built the circuit on a circuit boards and hope to do some test real soon.
I still need to build the I/O part that selects the drive ID and drive ROMs.
Also I need to program the ROMs with the various Kernals and drive firmwares.
It was about 6 years ago that I visited the club for a very short visit.
I met a lot of people with the same interest as me, and had several good conversations.
and a very interesting kernal selector based on a Atmel cpld chip.
If you are in the Netherlands on the third Saturday in the neighborhood of Maarsen (near Utrecht), it will be worth visiting their meeting.
