SD2IEC on ATMEGA32 - easier data exchange with my C128
Recently I discovered that my Time Pilot arcade PCB is broken. It works partly, its the graphics that is messed up. The cause is an eprom, where all of its legs on one side, just rusted off the socket. Some of these old PCBs are in rough shape. Not always treated well – especially after ...

“Amount to Words” and a Revival for a twenty year old book

Other than in my home country Germany, Cheques still play a big role here in Malaysia. Its been a pain to fill them out and frequently there’s an error and trouble with the bank. An idea was born, I need to write a software doing that job for us.  Well I am more into PHP ...

Glimpse into the world of Cycle Exact programming

The retro fever caught me again. I am these days quite busy with my RC models like helicopters and multicopters, but I felt it was time again to explore some topics around the Commodore 64 hardware. I stumbled upon the website of Michael Steil. He was the author of the 15 Second Disk Copy program ...

A harddrive gives me a hard time

The last two evenings I was fighting with the Megafile 30 harddrive of the Atari ST. The wiring is perfect and “something” happens between the ST and the Megafile but I don’t have any access yet.

My Latest Catch

Since I have moved from Germany to Malaysia, my collection of old games and systems grows a lot slower. However, I managed to get an ATARI 520 STfm for RM 125 (~ 30 Euro).

Retro Pearls on Android

Who was Gary Kildall?

Who was Gary Kildall?
Recenty I stumpled multipe times upon a certain name. It was Gary Kildall. Gary was the one, who founded Digital Research. The company who was well known for its operating  system CP/M, designed for smaller computers. In a time where mainframes were more common, than a personal computer. Some people might rember DR DOS, which ...

Retro time

Retro time
The last weeks I invested some freetime to get my C64DTV upgraded. The biggest thing I did was adding a SD-Card based Floppy emulation. This nice thing is driven by a microcontroller and called MMC2IEC. Another thing which I have planned for my DTV was, to change the Commodore standard kernal to a patched one ...
