            Dear Visitor, Welcome to my online shop. My name is Przemyslaw Krawczyk, but commonly I`m known to people of Polish Atari Scene  ( and maybe not only...but who knows?) as "lotharek". I`m very happy you got here.

           My mission is to deliver high quality devices in good prices. Devices, that follow modern environment standards (ROHS, Weee, Gios) and satisfy customer needs.  My devices are made at automatic assembly lines by PP ELECTRNONIX, parts are  supplied by MICROS in almost 90%, ABS casings are made by Maszczyk, metal ones by SESMIL. All my devices before postage are tested and checked personally by me, then securely packed. 

        Frequently I use EBAY.CO.UK ( look at my feedback left by customers)  to sell my stuff. Why UK ?? Simple, I have spent there two years of my live, improving my language skills and acquiring some western approach to life ;-)

      Time has passed,  upgrades have been developed and improved... Since 2008 I cooperate with Jeff - creator of SD and USB Floppy emulators, also new cooperation with Candle`o`Sin have been recently introduced, that hopefully will bring to life some new ideas for retro gaming enthusasts like me and you

    If you have interesting idea/project, do not hesitate to contact me. I may be able to commercialize your project worldwide.


     Also, worth mentioning is fact, that part of my income goes to those, who need it most. Thanks to your purchase I can keep on helping kids from Special Needs School in Piekary Slaskie. In addition, I`m one of the supporters of KID`S DAY in my JUDO CLUB, where big party is organised and money collected for kids. Last, but not least, I support almost every retro party I visit and Judo Club CZARNI BYTON as this sport - next to retro gaming -  is my passion.





Once again – Thank You for Your purchase and Your support.

 Please, remember - supporting me, You support all my charity activity we both shall be proud of.
