This kit is needed if you
want to use 1.44 floppies on your ST/STE/MEGA machines. The board is fully
automatic and will switch between 720K and 1.44 mode without the use of
drivers or special software or TOS patches etc. You can use internal or
external drives in either 720k or 1.44 mode.
V7 series fixes TOS206 issues where sometimes it is patched to work in
the wrong step rate mode for accessing 720K floppies. Also V7 series has
the media change fix so TOS behaves better when the floppy is changed.
V6 series is slightly smaller than the V5 and now uses single GAL IC. V7 also includes DMA pull up resistor which will help solves some DMA related issues.
You also need a modded floppy drive such as the one I sell HERE
. Please note if you use any other drive with this kit, then I will not
be able to assist if you have any problems. Please note the 1772 is not included in this kit. Image is for illustration and kit is not assembled.

Similar to CTCM but this module is set via a simple 22 turn resistor pot. This can be adjusted from 60MHz to over 100MHz. This module has been designed to work on CT60's which never worked with CTCM or where CTCM has stopped working for no reason. Please note I cannot guarantee it will work in all problematic CT60's.
As this does not require software, if overclocking locks up your falcon, you just need to adjust the resistor pot and reboot, simple! This module is ideal for working out the max speed of your CPU/CT60/CT63. Preset speed is approx 85Mhz.
Available until stocks are exhausted.
2x capacitors to Upgrade the failed ones in the ST/F/E Reset circuit. This fixes various power up reset issues.
The 3-in-1 monitor adapter is a small piece of hardware that plugs into the monitor port of the Atari
Falcon030. Its main purpose it to make it possible to connect the Falcon to a monitor using a
standard VGA cable. It also provides a switch to toggle between RGB and VGA video modes
(useful for monitors that accept both RGB and VGA frequencies), and an external clock signal to the
Falcon030 video chip (to enable higher screen resolutions) compatible with the Blow-Up software.
The monitor adapter comes with two oscillators of different frequencies which can be changed on the onboard socket. The oscillator provides an external clock signal to the video chip of the Falcon to make it possible to achieve higher resolutions than
the standard video modes when used in combination with the Blow-Up software.
NOTE: You need a 5V USB PSU to power the board (not included) I do not recommend using phone chargers for this either (You do not need the osc or power to the board to use standard falcon resolutions). The OSC has a sharp corner which corresponds to the sharp corner on the pcb silk screen print (do not go on the socket orientation) . The DB19 screws must be taken out of the socket to fit in the falcons video connector.
Adapter designed by dhedberg, produced by exxos.
A really cool breadboard PSU. Accepts 7-12V via DC jack input or obtains 5V from USB connector. Jumpers on board can switch between 3.3V or 5V output on both sides. Output current 500mA on 3.3V and 5V outputs.
All-IN-ONE cartridge PCB assembled and tested. Has Atari diagnostic software for, ST,STE,MSTE,TT,030. Also has the new RAM test software by chzsoft, and GEM BENCH 6 benchmarking software. Software is selected by jumper links on board. The settings for these are conveniently printed on the PCB itself.

Simple ST2VGA adapter to connect the ST/F/M/E to a multisync VGA monitor. Colour / MONO switches done by a simple jumper on top of the board. The adapter also has a standard audio output jack.
NOTE: your monitor needs to support 15KHz otherwise you are not be able to use colour mode)
SPECIAL OFFER INTRODUCTORY PRICE.
PCB & programmed PLD for R1C IDE project.
If you live in fear of your efforts of "fixing" your ST/Falcon PSU (which you should be as falcons are kinda expensive!) Then I suggest buying these dummy load resistors to test your PSU under load before reinstalling it back into your machine. NOTE you CANNOT test switchmode PSU's without a load, it will malfunction!
Resistors are simply pushed into the PSU connector. 5V uses 2.2R (loads 5V rail with 2.2amps) and 12V uses 10R (loads 12V rail with 1.2amps). Then you can measure the PSU under the load resistors and make sure the voltages are correct. Note these resistors are rating for continuous use, but get EXTREMELY HOT very quickly. So I suggest not running them for more than 30 seconds at a time. Connections to PSU connector are.. 10R in blue and black... 2.2R in red and black.

Tested 16MB 72pin 60ns SIMM. Ideal for RAM expansions for the Falcon etc.
Picture for illustration only.
Low cost assembled & tested 4MB RAM UPGRADE kit for later STF/M motherboards. Fits under the PSU section. It can be switched from 1MB to 4MB for software that will not run on 4MB.
Only fits later revision motherboards
such as C070789, Where there are normally 4 rows of DRAM as shown
Assembled 72 PIN SIMM adapter card for the falcon 030. PCB layout has been carefully designed to use the bulk of the copper area for 5V and 0V rails. Board has a generous 100uF ceramic capacitance for ultimate stability.
IMPORTANT! While the design is as small as possible, the top of the board is very close to the metal shielding, so you will need to use some thick card to use as a spacer to make sure the shielding doesn't short on top of the board!
Requires a 16MB simm which gives the maximum 14MB of usable ST-RAM.
The RAM upgrade plugs over the MMU and SHIFTER. The DRAM is compacted ontop
of the MMU adapter PCB making the design ultra small and compact and does not
require simms. There is a jumper link which can be connected to a toggle switch
to enable 1MB mode or 4MB mode. This gives maximum compatibility for ST software
which will only run with 1MB RAM. If your shifter is not in a socket then you
will need to unsolder the shifter to plug into the board.
The MMU board is supplied assembled. The Shifter board is supplied as a kit.
Cables are available to fit into MST/STM/STF/M and are now sold separately. See items 0014,0149,0025.
