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 ūüėõ¬†.

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).


New Commodore added to my collection

last month I got a Commodore 16 and bought a Toshiba HC10 (MSX) system.

The Commodore 16 has the same basic architecture like the Plus 4, but misses the 3-1 function ROM, user port and (6551) ACIA serial port chip.
It also has 16Kb of RAM instead of the 64Kb that the Plus 4 has.
The circuit difference of the RAM is only minor and can be quickly modified by supplying the A14 and A15 lines to the multiplexer and changing the RAM chips.
So this will be my first mod (keep you posted).

The Toshiba HC10 I bought is a MSX system. I bought it with two game cartridges and a Philips floppy drive controller cartridge.
Also a (DIY) external drive and monitor was supplied.
I bought it to play a little with the “different technique” MSX is using.
I will probably sell the system when I’m done playing.

Old project


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

Sandisk 4GB arrived from Amazon

This week I received from Amazon a 4Gb Compact Flash card.
When I used this card in the Amiga with a PCMCIA to Compact Flash card converter it worked instantly.


The other cards I have¬†(one of them is a 16Gb sandisk) didn’t work.
It looks like the other cards are trying to use another mode to communicate.

Also this week I noticed a new animation from Eric Schwartz:.

Progress on my A1200

Some weeks ago I received my compact cards and ide adapter.
I installed Workbench 3.0 on one of the Compact disks.
To speed up installation, I used WINUAE on my PC.
The disks connected by USB card reader.

After installing the Workbench I mounted the compact flash with the adapter in the Amiga 1200.
She booted up on first try (And a lot quicker than the original disk).
After this I inserted a PCMCIA to compact flash adapter, but¬†She couldn’t see it.
(cfd and fat95 installed),
So I ordered 2 Sandisk 4GB Compact disks.
I’m still waiting for those to arrive.


My colleague got hands on some old PCMCIA cards.
One of these card was a D-link 670, a cnet.device compatible card.

After some work, getting files to the Amiga using crossdos and PC2AM and several tries on configuring MiamiDX (TCP/IP Stack) I manage to get online.

As my Amiga only has 6Mb, lot of sites are not able to load, but aminet was no problem.

-getting compact flash working with the PCMCIA for easy file transfer
-Getting 2 16Mb GVP SIMMS (if price is not to high), Or wait for vampire 1200


Added a A1200 to my collection

18 August I bought an Amiga 1200, my fist 1200 I ever owned.
I had the choice to get a nice white Amiga Technology A1200 or a yellowish Commodore A1200.
I choose the yellowish A1200 as the internal HD was still running and the board doesn’t have the Escom drive fix (making the drive incompatible with some demo/games)
The Amiga also contained a GVP 1230 (Jaws) 68030 board with 4mb memory and another 4mb 68020 (Blizzard 1220) card.

The Amiga was used until 2006 by a local broadcast company in Tilburg.
