Besides exxos having a bunch in a bag, what does the supply look like for those PLCC MFPs?

Currently no problems in obtaining them.

:logo: - PLCC MFP from Socket to SMT

In the true spirit of SMT and as the chips a readily available we have replaced the PLCC MFP as SMT instead of a socket.

:logo: - Keyboard Connector RX Pull-Down / Pull-Up Jumper

We had a suggestion from @DoG

Can we do a pull up instead of a pull down on Rx on the keyboard connector so if you forget to plug it in, you don't have to hear the clicking? Drives me crazy every time I forget to connect the keyboard.

In H4 schematics it is R35 (10K ohm) tied to GND.
@exxos suggested we could do a solder jumper so here is our first user suggested improvement on the H4G.

Well a sort of in-between image ;) Was to lazy to go back and find the H4F version image.

:logo: - New Feature - DreamBlaster S2 MIDI Synth Header

We have been doing some tests and we are able to provide a DreamBlaster S2 MIDI Synth board header on the H4G so that you can play MIDI straight out to your monitor. There are 10R resistors so you can tap into the audio L/R lines and break them from the monitor sound line just like the YM 10Rs.

Video of testing the S2 Synth card on the H4F. It also works with games with MIDI too.

Great. Will the X2 also work/fit? Maybe move down the MFP a bit and xtal might need moving?
