MV1B1

The MV1B1 appears to be a newer revision of the MV1B board. I quick compare between the 2 shows the Z80 cpu and RAM chip next to the Z80 are different types/packages.

Board Scans - Set 1
This MV1B1 was a board I received from aliexpress/china. I'm pretty positive the NEO-BUF bypass seen on the front scan of the slot board is something they did and is not normal. I've seen this type of bypass for the NEO-BUF on other 1 slot boards from aliexpress/china. I don't see any other obvious mods / repairs to the board, but it does appear the corner of the 68k cpu is slightly melted.


 * The battery and heat sink on the audio amp were removed prior to scanning
 * The standoffs seen in the first scan are related to the scanning and are not part of the board itself

Here is on without the NEO-BUF bypass shenanigans.
