finaly I got the!cart and it needed the right home.
With the help of a cutter knife, dremel and hotglue it fits into a classic Atari 800 Cartridge.

I bought a cheap sio2sd and put it into a Atari 1064case.
Inspired from http://atariage.com/forums/topic/175988-new-case-for-my-sio2sd/
Some dremel, hotglue and time…
when using The!Cart or MyIDE II with atari you need to do a mod of some signals
Reference: https://www.wudsn.com/index.php/productions-atari800/tools/thecart/atari-800-fix
Only Cut one circuit and add a wire and you are done
For testing old Computers you will need a lot of different power supplys with AC and DC Voltage.
I put them together and we got one to rule them all 😉
Meanwell RT-65B and a 9V AC Power Supply
9V /2100mA
5V / 5,0A
12V / 2,8A
-12V /0,5A
So it works @:
Its time to bring up this little beauty to the level of a Atari 800XL.
An easy mod, because all parts in a Atari 600XL are socket and you only need to change 2 RAM Chips and do some wiring
Works with Pal and here shown NTSC Version
Remove U11 and U12 (was: TMS 4416-15NL 4bitx16k)
Replace with : MCM41464 AP10 (4bitx64k)
or : NEC D41464C-10 (4bitx64k)
OR : HMS50464P (4bitx64k)
or : any 4464 equialent (4bitx64k)

Atari 800 was my first computer after Sinclair ZX81 and its time to make the picture better. After checking the A/V Out it contains Video and S-Video in a good qualitiy. So i decided to replace the original DIN Connector and replace it with a DIN 13 like used in Atari 7800 french and Atari ST. I used some not needed pins from the Din 13 to put in Video and S-Video too. So its possible to use RGB-Output via a standard french Atari 7800 RGB Cable and with a special Cable made I can use Video and S-Video too via the same connector.
To put the DIN 13 in the right position i need some plastic and drilled holes downunder to make the Din connectors accessable
replaced DIN 5 to DIN13
downunder chaos
because of no space at the CPU Board I needed to move the Sophia Board to another place. I uses some ribbon extension like this
and here we go. In front you see incognito board too 🙂
after finishing up it looks like this
I got a white „dental“ case and its time to make the jaguar ready for 2017 😉
The title is something strange, but its comming from a Sega Saturn Mod years ago (the code is based on this). The Saturn reset button is used for change region and 50/60Hz.
You will need:
-pic16f630
-button
-RGB-Led
I removed the RF-Unit to put my „standard“ DIN Connector and for adding a button instead of the chanel selector. With the help of this tiny button you can select between 50/60Hz.
(Overview)
(U25 Pin 11 sets the Console between 50 Hz (GND) and 60Hz (5V)
I used a US 60Hz Jaguar for modding, so you have only to solder this wire to Pin 11
Attention If you use the PAL console you have to look downunder and remove a Resistor R140!
(The Reset Line you will find U9 Pin 13 (GND = reset)
I removed the original LED and put instead a RGB-Led.
I set red for 60Hz and green for 50Hz.
If you find blue better, no problemo. But red/gn are the real colors of the Jaguar used in their countrys.
Usage:
Its like the switchless Mod for the Sega Saturn.
a) When you push the button for a moment. The Jaguar will do a reset
b) you push and hold the button. Now the Color of the LED will toogle between green and red. When you release the button
at red -> Jaguar Resets and starts with 60Hz
at green -> Jaguar Resets and starts with 50Hz
(bigger hole for Din RGB-Connector)
(RGB-Pinout)
(Reset button)
(overview)
(my standard Din Pinout, based on modified 5 Pin Din PC-Engine + 3 more for RGB)
Its time to add a 2nd Bios to the Jaguar.
You have to remove the original Jaguar Bios and use a DIP 32 socket.
With the help of a 29f040 FlashRom I added jagbios and BJL1.06
You need to concat the bios files:
Use: windows command: copy /B jagbios.bin + jagbios.bin + jagbios.bin + BJL106.bin 4in1bios.bin
and burn 4in1bios.bin to the 29F040 FlashRom
(overview)
Update 23.6.2017
I put a switch beneath the Power Switch to make it like a „real switchless“ mod.
So the Power switch can pressed a litte to:
OR
Press it more deep to Power Off and Power ON like normal
I used a little switch with a ball at the end and put it inside like this:
standard
with button pressed a „little“

(Sorry about wrong JBL speaking its BJL Loader 😉
I used a old revision (rev1) of micros neogeo Receiver and put it inside of the A2600 6 swich.
I was modified before with A2600RGB from tim worthington and I used some more switches like select, reset from the Atari and extra button from tim worthingstons 2600RGB PCB
UWRC
Button A = normal FireButton 1 of Atari (Pin 6)
Button B = Firebutton 2 (Pin 9)
Select = Extra Button A2600RGB PCB
Start = Start of Atari 2600
Button C= Select of Atari 2600
Button D = Palette switch A2600RGB PCB
All normal Controllers will work after mod too. Like paddle, racing, joystick.
(diodes, needed to make special functions from A2600RGB working, R=10k as pullup)
RX Led to show it though the power switch hole upperside red led down side gn led
here you can see the grandpa of remote control 😉
a little comparsion between yesterdays remote and state of the art :-)))
I bought some Competition Pro Mini and most of them have brocken microswitches 🙁
I found some replacements here:
http://www.voelkner.de/products/43525/Microschalter-Ultraminiatur-5A-250V-Sim.-R.-Hebel.html
It was very tricky to add the Universal TX PCB in this tiny stick but after all it looks great 🙂
After removing original parts I add a Led and two more micro switches for Select and Start.
The chrome switch to swap between Layout Select/Start and Button X, Button Y
I must move the electronic of the LiPo to put it between the two fire Buttons
