Genuine TF536 PCBs with bird seed (bottom SMT parts assembled).
NOTE: Because of the virus it may take up to 3 months for your order to arrive. If you do not accept this, then please do not order.
NOTE: support is via the exxos forum only.
I also sell PGA sockets, item #0181, and 030 CPU item #187.
The successor to the V2.2 ST BOOSTER. This 2020 /2021 (rev 1.4) edition uses a smaller board and 16MHz DIP CPU instead of the PLCC68 HC variant. Booster comes assembled and tested with CPU ready to use. The booster also has the TOS206 decoding on board. You will need a suitable DUALTOS board. Currently I only produce one for the C070789 or MEGA ST boards. If you have a H4/H5 series remake board, then they already have a DULATOS ROM socket, so you can just plug in the booster and connect up.
This board was developed on the H5 series motherboard. There is no reason why this booster cannot be used on original ST/F/M machines (but may not physically fit in the case without further modifications), however all the mandatory fixes must be done prior to installation. As there are so many issues with original machines and there could likely be other problems, particularly across the vast number of motherboard revisions, I am not officially supporting this booster with original machines anymore.
TF536 ST EDITION REV 3 PCBs with bird seed (bottom SMT parts assembled). The ST EDITION TF536 has been modified to work better on the ST series of machines and includes a on-board ROM socket and built in TOS206 decoder. Board works with 64MB TTram. The IDE port is not functional on this pre-release beta board.
NOTE: There may be a few days delay before shipping commences. Also note, this TF536 variant is not compatible with previous generation TF536 boards or firmware and is not compatible with Amiga etc.
I also sell PGA sockets, item #0181, and 030 CPU item #187.

74F257 DIP 16. Update or replacement for the 74S257 commonly found in STEs.
I have tested these CPUs in a TF536 on a ST at 50MHz by running them for a minimum of 2 hours doing constant integer divisions to heat up the CPU as much as possible. I have also run GB6 several times to visually see there is no corruption.
These will be stamped as RC33,RC50 etc. Though as China reprints them all, its really irrelevant what's printed on them anymore. Picture for illustration only.
I also sell small stick-on heatsinks item #0222

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.

New Sony MPF920 floppy drive updated which are working to the maximum extended format of
22 sectors 86 tracks. These drives are later MPF920 models which work reliably
on Atari computers (some early MPF920 drives are not reliable) These drives
are a ideal as a replacement drive or to match my 1.44 floppy kit upgrade.
Please note some minor case modifications are needed around the eject button. See HERE and HERE.
If you are replacing a 720k drive and plan to use this drive with 1.44 floppies, then you need one of my floppy upgrade kits #0041
Please note The floppy cable needs to be inserted upside down to use this drive and you will need to modify the internal jumper to use as a internal floppy drive as shown the info link.

Replacement drive belt for the original long button floppy drives.
Standard 4 pin floppy power cable. approx 6 inches long.
The purpose of this board is to alleviate the problem of having to physically twist the cable and using a more modern MPF920 1.44mb floppy drive. It also solves the problem of having to dismantle the drive to alter the drive ID select. Also as noted the mandatorily fixes, the 1772 needs pull-up resistors to function correctly and these are also included on this board!
NOTE - While you can use a 1.44 floppy drive, this board does not add 1.44 support. You need a kit like ITEM #0041 to add support for 1.44 floppies.
A useful 10 inch (approx) custom made extension cable to extend the internal floppy drive cable. Will allow HxC2001,gotec etc to be fitted internally should the current cable be to short.

Trudie V5.2 BETA, a acronym for "True IDE" is a advanced IDE interface with automatic byte swapping. This allows you to use CF cards in Windows and ST without the slowdown of normal byte swapping in software. Trudie operates at the maximum possible speed on a 8MHz system. Unlike other inferior IDE interfaces, Trudie supports a wide range of CF cards.
NOTE: You need at least HD8.47 by Uwe Seimet www.hddriver.net to use Trudie. This is 5V only BETA. IDE interface has already been proven and tested in previous builds, though byte swapping (only currently tested in TOS206 with HD10,11) Is new and is in BETA testing. Price for final versions of 5V Trudie will be at least double. V5.2 is sold at discount because of BETA version. Trudie V5.2 is designed for 5V ports on H4/H5 motherboards. It should also work on original machines with all the mandatory fixes done, but is not officially supported.
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 a 40MHz oscillator which can be changed on the onboard socket for a faster one such as 50MHz (sold separately , but not all Videl will apparently run at that speed) . 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.
I strongly recommend also buying a diagnostic cable to hook up your ST to your PC should there be no video output etc item #0191
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)
Virgin C070789 STFM MOTHERBOARD. Revision will generally be C,D,E,F. These include TOS1.04 UK which is the rare original ROM's. They come with 512K RAM which is also tested. These boards power up and run GemBench6 just fine. These boards are the best revision for modding and tweaking.
I must however stress due to the age of these boards and the rough postal system, I cannot guarantee operation on arrival. So buyers must take this into consideration and expect some troubleshooting. I will package these are carefully as possible.

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.

New designed PSU to fit STF/M/E/MEGA ST/Falcon machines. Features include safe low voltage operation via a efficient toroidal transformer. PSU has much better regulation (10x easily) and cooler running than the original Atari PSU's. Fits on original PSU framework (not included). PSU connector not included (see codes 0095 & 0163 under connectors section).
PSU can deliver up to 5amps on the 5V rail and up to 3amps on the 12V rail. Design only use 1 bulk electrolytic and uses SMT ceramics. Click the info icon for more info.
NOTE: PCB colour is currently blue. There are a couple of red ones left ( at the time of typing) , request red in checkout notes if you prefer red.
Refurbished and re-capped original PSU. These have been updated with quality switchmode rated low ESR high current capacitors and a new original PSU switch. Picture for illustration only. PSUs are generally DVE,ASP,SR98 types.
These have been refurbished by Steve from solidstatesociety.co.uk
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
DO NOT ATTEMPT TO INSTALL THIS UNLESS YOU ARE GOOD AT SOLDERING. IF IN DOUBT GET SOMEONE TO FIT IT FOR YOU AS DIAGNOSING DAMAGED MACHINES IS VERY COSTLY AND NOT A SERVICE I OFFER ANYMORE.
Tested reconditioned simms sold in set of 4 (1MB x4 = 4MB) .
Picture for illustration only. Sets may include different brands,speeds etc, this does not have any effect on operation.
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. Advantage of a simm are they are easy to swap when experimenting with bus speeders and as DRAM is prone to failure, it is easy to change should a DRAM IC fail.
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.
Shifter adapter PCB for the 4MB MMU kit ( item #0030). This is a spare shifter PCB kit, includes PCB, capacitor, ribbon header only.
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.

New simms manufactured & tested in 2019 by exxos. This is a kit of 4 simms (4x 1MB 30 pin) to upgrade the STE to 4MB of ST-RAM. Simms are 70ns non-parity. Lower power consumption.
Please note the PCB colour of the 2019 batch of simms is now blue.
Only handle and insert these simms on the OUTSIDE of the PCB (not the center as it can cause damage due to board flex).
NOTE - if you have previously used simms greater than 1.5mm thickness on the connections, you will have to change the sockets as such simms are to wide for the STE sockets and will likely have damaged them.
New DRAM 1x256k Supplied as chips on antistatic
foam. This will upgrade 512K machines to 1MB.
Note this only works with machines with the RAM banks as shown in the image, or C070789 Type motherboards.
Note: various brands or speeds of DRAM may be supplied. This in no way affects operation. Kit includes 3x33R resistors. Capacitors are sold separately.

TOS4.04 FAST ROM (not cheaper/slower eprom type) . Either
a update or as a replacement for Atari Falcon 030 / C-LAB machines. These
ROM's are verified working with zero waitstates on the Falcon which gives
a small boost overall in machine speed.
NOTE: Other Falcon ROMs may have the same number as in the machine already, or sold elsewhere, but are likely not fast enough for zero wait states. The ROMs sold in my store are always fast ROMs. Price jump is due to increased cost in sourcing ROMs!
