Now in blue:

Maybe someone will be interested in what cassettes from the USSR look like. I have several pieces.

The smallest version of the cartridge housing specifically for boards Super Salt by C64iSTANBUL. Perhaps I will adapt the new versions of the boards to such a small case.

Blue&White version of the "Shrinked Cartridge" housing:

Created a new project on PCBWay for shrinked version of SXEGS Cartidge. Just in case. Link to shrinked version on PCBWay

Yes, strange problem on PCBWay. I have updated the Gerber files of the project, but the old PCB sizes are showing, although the files are showing the new ones.

PCB model: PCB in housing: With closed cover:

Link to PCBWay Project Try clearing your browser cache. You need Gerbers from "XEGS Cartridge_2022-11-10.zip".

But, you will need a new "shrinked" PCB (fresh from PCBWay or from GitHub).

Soldered another one. Works great right after soldering. Also, this is a soldering instruction

Cartridge dimensions reduced to 84x64x20 mm. Updated Project on PCBWay and Project on GitHub.

I think I can remove about three millimeters from the side of the connector. The pocket is too deep in my opinion. Maybe a little from the other side.

Now dimensions is 90.75x64.0x20.0 without logo and notches for pulling out. With notches and logo - 90.75x66.0x21.0. 1mm notches from each side (+2 mm wide) and 1 mm (height) logo. SikorSoft housings: 85.0x65.0x???. What are the maximum dimensions allowed for ATARI 800 ? Will 88mm be enough or do we need 85mm? And yet, what is the height from the bottom of the cartridge to the board ? I made the cartridge so that its bottom was at same level as the table when used with the ATARI 65XE/130XE.

But... Where is the lid ? 1200XL doesn't have a lid?

Can you take some photos? Perhaps I need to make a chamfer on the case, reduce the height or something like that. There is no lid on the XE series, I can't check.

"Instructions for creating a binary firmware file to flash in SST39SF040" added to README.md file. https://github.com/prcoder-1/ATARI-SXEGS-Cartridge

I plan to do this, but a little later. In the same repository on github. And yet, as I understand it, it is necessary to create an instructions in English on how to create a binary files for flashing in EEPROM.

Cartridge and PCB size reduced by 2mm to achieve 64mm cartridge width. For the new version of the case (v3 - 64 mm), only the new board (XEGS Cartridge_2022-11-09.zip) is suitable, the size of which is also smaller by two millimeters in width. PCBWay Project GitHub Project

Yes, it looks like I can remove a millimeter from each side of the board without side effects. Then, the housing can be made two millimeters narrower.

My cartridge housing: And SikorSoft cartridge housing: One millimeter difference in width. And, the board snaps into the grooves of the case. This might be a problem... I will probably have to reduce the PCB by one millimeter.

Very strange geometry. Never seen ATARI 1200XL from this side. I need the exact dimensions of this entrance hole. And what about the ATARI 800XL ? It with the same entrance hole or not ?

And what are its dimensions? Can you measure it?
