That would be me, unfortunately there are no project pages I was just swamped with other things and dropped the ball :(

To be clear, I'm looking for the project page, where one assumes the projects are discussed in detail, not the OSHPARK Link where one can order the PCBs.

I was pleasantly surprised to find out that it costs the same $6.30 if you order 1 board or 3 boards. Plus I chose the free shipping. Also ordered the other parts from Digi Key. So... total cost to me was under $25 for everything shipped. This is enough parts to build 3 of them. Not too bad. Thanks for the tip!

This would cover the bad RAM. So this looks correct. If it is a Model 100 the modules were available form Arcade Shopper https://www.arcadeshopper.com/wp/?page_id=11#!/8k-RAM-module-for-Model-100/p/104430801/category=28313042<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.arcadeshopper.com%2Fwp%2F%3Fpage_id%3D11%23!%2F8k-RAM-module-for-Model-100%2Fp%2F104430801%2Fcategory%3D28313042&data=02%7C01%7C%7Cfad5f45a1462444cb82e08d727bf8cad%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637021575957814064&sdata=Zm2zYgxccp4APvqynwnMJgs1KIM%2FwyZl4GGra50UlRo%3D&reserved=0> but they appear to be out of stock. There are a few list contributors who also build 100 modules they might have some built and OSH Park has the PCBs to build your own modules if you want to go down that route for example: https://oshpark.com/shared_projects/V0tpeuMg<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Foshpark.com%2Fshared_projects%2FV0tpeuMg&data=02%7C01%7C%7Cfad5f45a1462444cb82e08d727bf8cad%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637021575957814064&sdata=p3fN0Ls1IUL4LD%2FBIaqIthOXGU4a2d7PbPIC2tMTbHw%3D&reserved=0> there are others out there From: M100 <[email protected]<mailto:[email protected]>> on behalf of "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Reply-To: <[email protected]<mailto:[email protected]>> Date: Wednesday, August 21, 2019 at 4:31 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [M100] Need help with bad RAM identification and replacement Can someone verify for me that B000-BFFF would be part of the M7 (Option RAM #2) RAM chip? Of the four RAM chips, this is the second one from the left. Second question is... where can I buy replacement RAM for this? I am good with a soldering iron so I realize I will have to desolder the existing bad RAM and socket it and pop in the new RAM.
