New 130XE RA Adapter Boards

New to the site are these 130XE specific RA adapter boards.  Right now I am offering these on a pre-order basis.   They compliment the Dual RA Cart Adapter board I already offer.  I am also working on the details of a full 130XE Cart/ECI right angle switcher board.  Just need to work out how best to deal with the various configurations of cart/eci devices.

Not to leave out the 600/800XL entirely I am also planing on offering a Dual T cartridge port adapter board.  Hopefully in the next few weeks.

Reimaged XF551 for 3.5″ SF314/SF354 Floppy Drives

For some years there has been talk of using 3.5″ floppy drives instead of the original 5.25″ drives with the Atari 8-bit line.  It is not a fantasy, in fact it has been an accomplished fact for years.  Essentially take an original XF551 case and motherboard, use an adapter for both the internal data and power cables, pop in a compatible BIOS, use a 5.25 to 3.5″ drive tray converter and put the cover back on.  Presto!

There’s even been some attempts at a special pcb for a 3.5″ drive using XF551  derived circuitry.   Though the enclosure was none existent.  Review of Polish 3.5″ 8bit floppy design

Now I am able to offer a somewhat different approach.   With the assistance of tf_hh and manterola from AtariAge.com I have developed an Atari SF314/SF354 ST case compatible version of the XF551 circuitry with builtin 3.5″ floppy drive support.  It is a bare board pcb only, but I will be offering both a BOM and assembly instructions.  Further details can be found here
