A high quality enclosed compatible power switch for the 2600 JR console.
Please note, that because the original switches have a offset pin layout, these switches are actually dual pole, where you must cut off one row of pins in order for the switch to fit into the motherboard.
Mod boards to replace the horrid JR push switches with proper clicky switches (like used in mice buttons).
Click (i) for more information on fitting etc.
New boxed 2600 compatible replica joystick boxed. Will also work on ST machines etc.
New injection molded 2600 / 7800 cartridge shell. Looks and fits like the originals.
STE V1 booster runs the CPU & ROM at 32Mhz giving up to 220% speeds compared to a stock machine, and over 360% with blitter enabled.
This booster also needs the STE FAST TOS kit sold
HERE
DO NOT ATTEMPT THIS UPGRADE IF YOU ARE NOT GOOD AT SOLDERING AND DE-SOLDERING.
The next generation of booster is the V1.5 version which will fit the majority of ST/F/M motherboard revisions. V1.5 runs at 16MHz CPU & TOS and gives up to about 50% speed boost. In order for the ROM to work at higher speeds, the ROMs need to be replaced with a suitable "Fast-ROM" kit which I also sell (see HERE). There is a pad called "SW" which can be connected to a switch to link the wire to 0V. When SW is left disconnected / floating, it enables 16MHz mode. When SW is connected to 0V, it forces 8MHz mode. This booster is assembled and tested as shown in the image. NOTE: If 16MHz is unstable then you will need to change the 10K SIL arrays for 2.2K on the motherboard.
The V2 is the next step from the V1.5 booster. While the V1.5 has a separate TOS104/TOS102 board, the V2 has the ROM "on board" which holds TOS104/TOS206 which is selectable by a jumper.
V2 is 16mhz boost on CPU & ROM the same as the V1.5 booster, only as the V2 ROM decoder is GAL based, it is marginally faster than the V1.5 booster. Similar to the V1.5, there is a option to switch back to 8mhz mode.
This booster is assembled and tested as shown in the image.
Please note as this board is large it will only fit the Later revision
STFM boards C070789 series due to space restrictions on other motherboard layouts.
Note: If fitting on the MEGA ST then you will
need the MEGA BUFFER board otherwise 16mhz mode will be unstable.
Buffers the 16mhz line on the MEGA ST for stable operation of all my boosters.
GAL IC, 2 resistors, 2 capacitors, header pins are supplied in this kit.
NEW YM2149 IC for Atari ST etc. Controls parallel port and chip Audio.

Ideal for 16mhz boosters or just as a direct replacement for the old 8mhz CPU.
NOTE - you cannot simply change the CPU for faster speeds, you need a CPU booster for that.
Tested replacement GLUE C025915-38A for the Atari STF/M/MEGA ST computers.
New RTC chip to replace the older/faulty NVRAM chips in the Falcon.
This design uses a external CR1220 battery (not included) to power the RTC module.
This module is assembled and tested.
Suitable for the Falcon or any other machine which requires a 68882 FPU. Current stocks are overclockable to 64mhz.
Genuine 060 REV 6 CPU. I have clocked these at 90-100MHz.
These CPU are stamped 002 and are a earlier production run of the REV6 E41J mask. These are NOT fake REV6 CPU's (normally stamped as 002) as sold all around the internet.
Please note - These CPU's can have various numbers on them, but are all tested as genuine REV6 CPU which I have personally tested over 95MHz. Also CPU may have small marks or scratches on the top, this is purely cosmetic only.
A video of 100MHz speeds on Atari CT60 booster.HERE
These are supplied in anti-static foam. Prise off slowly working around all edge of the CPU. DO NOT rip the foam off from side to side as it will bend the pins! Double check all pins are perfectly straight and clean before insertion into the CPU socket.
Available until stocks are exhausted.
Quality black compatible printer ink in a single 5L container. This ink doesn't block your printer heads like a lot of cheap refill inks sold around the internet which can contain many impurities and often watered down for the "cheap price". Easily make a saving of £200 over buying smaller ink bottles in other refill kits.
This ink is manufactured in the UK by jet tec, a leading brand of remanufactured inks in Europe.
I have used this ink for years in my own Canon IP4500,HP8500, brother & epson printers. Selling these containers (possibly have a lot more) as I bulk bought ink a few years ago and purchased way too much black ink than I could use myself! Selling at cost as I need the space back!

Updated design over the previous V5 series. 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.
V6 series fixes TOS206 issues where sometimes it is patched to work in
the wrong step rate mode for accessing 720K floppies. Also V6 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.
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 only once assembled.

Kit includes 2 assembled mini PCB's. Header stripes are supplied but not fitted. Please see the information link on how to install this kit. Please note this kit might not solve all audio issues but I need reports back on people installing this to see what it is and is not solving.
UBE Video Switch V6 by Urban Jonsson.
This compact PCB plugs into the STF/M/E/MEGA ST video port and outputs to a VGA connector. So you can plug it into multisync or 15KHz capable monitors which will accept the ST's video resolutions.
The board also holds 3 trimmer resistors to alter the RGB levels. 3.5mm A/V connector with volume control and autodetection of resolution (in software).
12V 40x40x20mm. Very quiet, will fit MEGA ST PSU. BLUE=0V. RED=12V
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.
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.
This PSU is a must for people looking to power anything more
than a stock ST machine or is having random crashes or faults for no apparent reason.
STFM / STE PSU which has been upgraded with high current low ESR genuine
Panasonic capacitors (not cheap un-branded alternatives) to provide a
clean stable power rail for aged or failing ST power supplies.
The bridge rectifier
has been updated with higher wattage version due to the smaller WO5
being prone to failing. Key solder joints have been re-soldered to ensure
a secure connection to the main switching transistor and pulse transformer.
SR98's have had resistors changed to improve regulation. NEW switch fitted.
Image for illustration only. Types are generally SR98 or ASP34 etc

NOS 16MB EDO 72pin 60ns SIMM. Ideal for RAM expansions for the Falcon etc.
72 PIN SIMM adapter card for the falcon 030. Requires a 16MB simm which gives the maximum 14MB ST-RAM. 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. PCB is assembled and ready to use (16MB simm not included).
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!
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. Ask if in doubt.
New simms manufactured in 2017 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. Gold plated contacts.
SIMM's are now supplied with one side "tin plated" for better fit in some worn sockets.
Please wipe any residue from the simm contacts & clean the STE sockets with the included IPA wipes before insertion.
New compatible SIPP simms manufactured in 2017 by exxos. This is a kit of 4 SIPP simms (4x 1MB 30 pin) to upgrade the STE to 4MB of ST-RAM. Simms are 70ns non-parity. Lower power consumption. Gold plated contacts.
Pin contacts are 0.5mm dia. SIPP is 29mm high in total (top of PCB to bottom of header pins). Please make sure these will fit your machine (they may fit other machines other than the STE but I am unable to physically test)
Low cost 4MB RAM UPGRADE kit for later STF/M motherboards. Fits under
the PSU section. Simm itself fits to the right of the PSU and to the left
of the shifter housing. Some minor metal editing on the atari top metalwork
will be needed. PCB can be switched from 1MB to 4MB for software that
will not run on 4MB. Requires assembly.

Really useful for switching stuff.
New replacement reset switch to fit most ST/E/F/MEGA/Falcon machines
Suitable for most Atari PSU's using a similar looking switch.
Suitable for most Atari PSU's such as STF/M/E/MEGA/Falcon. Not these are single pole so the neutral wire from the mains socket is to be soldered directly to the PSU PCB. These switch are totally black as shown in the image. Mostly these are used on later machines such as the falcon and have a very nice switching action on them.
I strongly recommend these switches for use with my own designed PSU.
Ideal for contacts where air may cause corrosion long term.
Suitable for ST PSU connections, Socketed IC/chips, PC power leads, car battery terminals etc.
Supplied in 1ml syringe with approx 1ml contents. Ready to use. Insert blue plunger. Remove red cap and fit grey syringe tip. Apply to contact surfaces and attach. Wipe excess grease off with cotton swab or tissue.
