WANTED: Neo Geo MVS IC development cartridge with SNK NEO-MVS PROGMC2 / CHAMC2 boards

[NeoHomeBrew]

Hello,

I am looking for a Neo Geo MVS IC development cartridge for Neo Geo game development purposes.
These cartridges have SNK NEO-MVS PROGMC2 and CHAMC2 boards each with two connectors for IC Flash Memory Cards.

I know these cartridges are very rare and therefore I would offer $6000 or more for a working unit (depends of the content of the IC memory cards).

Here is a picture of the cartridge boards I am looking for:

Maybe reconsider buying the original SNK ones (if you can find one for sale). There is a new version that was being worked on:

Yes, I know about this project (I was the thread starter at Yaronet) and I am in contact with HPMAN who is working on it.
He has successfully build a working prototype PROG board and is currently working on the CHAR board design.

It would be quite helpful to know everything about the design of the original SNK IC card dev boards to be able to rebuild them properly.
This project is the main reason why I am searching for the original boards. The cartridge would not be "abused" as a working horse but
I want to learn from it and would like to document the technical details.
