Finally an update on the kernal selector for the Commodore 16

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.

Upgrade the Commodore 16 to 64Kb of ram

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).

 

Old project

IECATA

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.

Later some other sites like www.dienstagstreff.de and 8bit.yarek.pl picked up the idea and made new versions of this project.

 

Happy new year

A Happy New Year to all of you.
Hope you all will have a good 2017.

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

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 ESP8266devices.
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.

The Dutch Commodore club

This Saturday I went to the Dutch Commodore club in Maarsen.
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.
On the club I noticed that Gideon (the creator of the 1541 Ultimate) was there with the prototype of the new 1541 Ultimate II+.
and a very interesting kernal selector based on a Atmel cpld chip.
The Commodore club is a place where other 8-bit computers like Atari and TRS-80.
If you are in the Netherlands on the third Saturday in the neighborhood of Maarsen (near Utrecht), it will be worth visiting their meeting.
See their website for pictures of the meeting and meeting dates at:
