MSX1 Homebrew Clone for Baffa-2 Project

When I was assembling all the PCBs for my MSX2+ project, I used all the compatible PCBs that were available in the MSX1. And since there were still the VDP 9918, the Beer IDE and the 64KB Ram from MSX1 project, why not build another one? 

To do this, it was necessary to assemble a new Clock, CPU, PPI, Clock and PSG.... PCBWAY minimum order is 5 pieces, so I still have some spare parts :)...

Above MSX2+... Below (and connected to monitor) MSX1

Baffa-X (Baffa-2 with MSX Boards) now has a Wifi Modem based on 16550 and Esp32. It's similar to original Baffa-2 SIO Board and compatible to BadCat Card software/terminal.

Finally, I could test all the boards together. Now, it's possible to upgrade the Baffa-X from MSX1 to MSX2+. It replaces the VDP v9958 (compatible with other Baffa-2 projects), Memory of 64KB by  1MB Ram Board (megaram) and adds Rom/SlotExpansion and RTC Boards.

As we know, the V9958 package has no notch (hole). All fake V9958 have the same code 2703 2122 IACC, and we can notice the painting of the label that is different. (the last one at bellow is the original IC)

Hi folks, 

 bad news. The retro market is flooded by rebranded v9958  fake chips. I bought six already from different Aliexpress stores and all came with the same serial and "notch".  As we know, the package of yamaha v9958 has no notch. (Example on figure bellow)

For while, I tried those six I received from Aliexpress stores. All have the same code and manufacturing date:

 It seems that the are rebranding "toshiba" 64 pin ics like 68000 or 1253. Compare for yourself....

Unfortunately, this is leading to a price dispute and ruining the MSX2+ spare parts market. And this project is stopped waiting for a part that works.

My first v9958 was about 10 usd on august, 2022. ... Today (march, 2023) I got a quote of 111 usd from utsource.

The new MSX2 setup is coming soon.

1MByte Memory Mapper working correctly. This board is part of the new set of boards to transform the Baffa-2 MSX1 into an MSX2(+) compatible computer. 

I'm waiting for the missing components to arrive to finish the other boards. News coming soon.
