One Chip MSX

MegaFlashROM SCC+ SD


This unit got enhanced by adding a audio out jack.



ATA-IDE+RS232C interface

Tweety has this IDE interface by Sunrise built in in order to get life into the Compact Flash reader which is built into its case.


F - 1 Spirit is a MegaflashROM SCC 512 with a subtle switch.

The cartridge in the middle is a MegaflashROM SCC 512 of which the origins are unknown.

King's Valley II still is a game cartridge. It's unknown if it will remain like that. There's a switch though.

Update (while the photo is still online): King's Valley II lost its switch, became a game cartridge again and was dropped in a bucket of prices in hamlet's 2018 christmas quiz.


Padial PS/2 Keyboard interface


WORP3 designed a brilliant piece of hardware. This cartridge converts every MSX-Music (FM-PAC) signal to MIDI data and outputs that to any synthesizer in GM mode. It does have some limitations. It can support up to 16 (I believe) instruments which you can map to a driver. So every piano on your MSX-Music will be routed to just one piano sample on your synthesizer, every string on your MSX-Music will be routed to just one string on your synthesizer, and so on. So you've to map your instruments very carefully to get a driver which suits your synthesizer best. But then still, there will always be tunes which sound awful with this device. Due to its limitations I like it. It bumped quite some new life in old MSX games. You can write your own music for it using your old faithful tracker which supports MSX-Music. I'd pick Moonblaster 1.4. Check the Youtube menu. In the center column there is an ever growing list of tracks made in Moonblaster 1.4 in combination with MIDI-PAC.

When mixed well and if MIDI-PAC hasn't shut down your real MSX-Music (it does this with some software) you can listen to MIDI-PAC and MSX-Music at the same time. Both chips/synths complete each other quite well. You'll hear the sound you're used to with some modern real instruments added on top of that.


WORP3 made a second MIDI-PAC. This version not only supports more instruments, it can handle PSG as a source as well.


In the mid nineties Sunrise developed and produced an OPL4 soundcard for MSX. As the tracker that came with it was written by Moonsoft, the name of the cartridge was Moonsound.

Mine is version 2.0 and has had its shares of dying moments. Just when I started to pick up my MSX activities again when the new millennium had just started, I found out that one side was mute. It turned out that a pre-amp had died. Sunrise replaced both left en right pre-amps for a higher quality version and added 512kB SRAM to its original 128kB. It worked some ten years until the OPL4's wave part totally died. Sunrise replaced the synthesizer and added even more SRAM to reach 1MB.

In the meantime I bought a Korean clone named Dal-So-Ri in case my Moonsound would die. I received it just before my Moonsound did die. What a coincidence.

The third OPL4 cartridge is the white FM Blaster by the French Repro Factory. The name is somewhat unlucky as FM is only a part of the cartridge and there is little to no support for the FM of the OPL4. It is a clone of Wozblaster. This cartridge is a rather silent OPL4 one compared to the other two I have. Just cranking up the volume of the amplifier is not the most satisfying solution as the noise gets amplified as well. Therefore there's a solution to this problem.

When Junsoft decided to make an update of Dal-So-Ri by adding several new modes, including some MSX-Audio features, I couldn't resist.

I recently added a Shockwave 2 by Tecnobytes to the collection. I still have to try it, but they claim it has a better DAC than all the cartridges on this photo. I'd like to check it out. You'll probably hear my verdict some day.

MSX Audio

I have four Philips NMS-1205 Music Modules. There's one with 256kB sampleram and a 7MHz adaption, one with 256kB sampleram, one with a 7MHz adaption and one without any of all that. None of them has the silly software built in anymore.

The one with the pale colors went into the slot expander which is built in to Tweety.

MSX Music

The FM-PAC is an invention of Panasonic. It contains FM and PAC. PAC was a cartridge which has some S-RAM to save game states on. Only for games which support this feature. Later they came with the MSX Music format and put this together with the old PAC in one cartridge, hence FM-PAC in which PAC stands for Pana Amusement Cartridge.

Later Panasonic released MSX2+ and MSX turbo R computers in which they installed the MSX Music so they halted the production of their FM-PAC. A lot of clones without the S-RAM were manufactured by several hardware builders in the hobby scene.

Out of the box this cartridge does not have its own audio output. One of mine has a custom cinch output on it so the audio can be separated from the audio coming from other cartridges. It has an English patched firmware installed and is built in to Tweety.


I bought two FM-PAQ lites by Eric Boez. One was going to be installed in Tweety (but that never happened) and one was going to be used as MSX-Music replacement in my turbo R. I am absolutely not satisfied with the poor audio quality of this computer. And since Panasonic's FM-PAC is being switched off in machines with MSX-Music built in I had to do with this.

Both FM-PAQ lites received an output decreasing resistor of 33K on R9 to avoid triggering the clipping LED on my mixer. Eric Boez delivers them quite a bit too loud.

MSX Club Gouda 1 Megabyte external memory mapper

An external memory mapper of one megabyte by MSX Club Gouda. It doesn't work as expected on my Panasonic FS-A1WX and therefore it was obsolete until I received my MSX turbo R. It claims to work on that computer and so far it proves to do so.

I guess my FS-A1WX was too rare in the era when these cartridges were made and tested.

It claims to work on a turbo R. Well, it gets recognized on boot and in slot peek programs, but the turbo R does not use it since it only addresses internal RAM.

MSX Club Gouda Slot expander 5.0

One of the nicest slot expanders around. The MSX Club Gouda slot expander 5.0. it does not need external power, so it is expected that the used MSX has a PSU strong enough to power the filled slot expander.

Below a picture of a situation which not every MSX can handle:

The audio rack

In this rack there are several different 19 inch units. From the bottom up the stack consists of the following machines:

  • Roland Fantom XR synthesizer with 512MB extra sample RAM.
  • Roland JV-1080 with the SR-JV80-13 Vocal expansion board mounted.
  • Roland XV-5050.
  • Behringer RX-1602 mixer
  • M-Audio M-Track Eight audio interface.

The Rack Mixer

This Behringer RX1602RX mixer is filled with the following

  • Roland XV-5050
  • Roland JV-1080 with the SR-JV80-13 Vocal expansion board mounted
  • Roland Fantom XR
  • Korg X5D
  • PSG/SCC from MegaFlashROM SCC+ SD's custom jack out
  • MSX-Audio
  • MSX-Music
  • OPL4


Then there's an old picture of my two Korg X5D synthesizers together. Why two? Well, at the time I just could. I wouldn't want two of them now, but I already have 'em. There are however extra features when having two of them. A Korg X5D is actually just an X5 with some extra samples. These extra samples are being stored in a separate sound bank. Switching between the two is quite a hassle because Korg wasn't really thinking as a user when they made this thing. So when having two, you just have to play the other if you want the other sound bank. Another is that when connecting both synths, you can play more notes simultaneously. One plays the even notes while the other plays the odd notes. Slowly decaying sounds won't be cut off this way.

I only use one of them as a master keyboard while the other is in storage.

Commodore Amiga 1200

The latest addition to the retro computers is this Commodore Amiga 1200. As may be expected, this machine is not in its default condition. Just recently all capacitors were replaced and a CF card serves as mass storage medium. To easily swap data from and to the pc there's a PCMCIA CF adapter. Then there's some other extra board installed inside it, but I have no clue what it is.

This machine was bought to find out how easy it would be to do some chip tunes on it. Well, it turned out that the built in sound chip called Paula is quite a limited and useless invention. It's just four channels which are hard panned to either left or right. There's no control on it. So if you want to play a note on both speakers, you have to use half of your channels. The audio quality is quite poor as well. Therefore I am very delighted I got a MIDI Master with which I can control my synthesizers. There might be a nice musical future for this computer.

The PC

The work PC on this desk is a self built machine which got some extras and upgrades since the basic machine was built. As the main board is an old Asus P8H67 there were some limits to what I could make of it. The board has been degrading through time. The onboard soundcard went bad and the onboard network card told me to stay offline as well. Both were replaced by external cards. The audio card even got its place outside the casing in the shape of the 19 inch M-Audio M-Track Eight USB audio interface. The casing, a Coolermaster Silencio 550 has a USB3 port on the front panel, but the main board lacks the connector, so in order to get it to work I had to fill up a PCI port with a USB3 cart. It works, but not very well. This time it's not the fault of the main board, but it's the casing.

As you can see the PC has had quite some patching. So you might ask me why I didn't change the main board. The answer is simple: laziness. Installing Windows and customizing it completely back to how it's now is just a hell of a job. And since this computer has been expanded to the maximum of what the main board can handle and it performance is higher than my needs, it's a good way for me to prevent me from buying things I don't need.

So what kind of PC is it in total?

  • Coolermaster Silencio 550 casing
  • An old Huntkey 400 Watt PSU
  • Asus P8H67 main board
  • Intel Core i7-3770 processor
  • Asus GTX1050
  • 2x Kingston 8GB DDR3 1600 RAM
  • Samsung Pro 860 256GB SSD system drive
  • Seagate 3GB bulk drive
  • TP-Link 1GB network cart to replace the broken onboard RealTek network cart
  • USB3 cart to benefit the USB3 port on the front panel of the casing
  • M-Audio M-Track Eight audio interface to replace the broken onboard RealTek audio cart
  • An extra cart reader in the front panel to work with CF carts
  • An external cart reader in the vicinity of my MSX for easy access
  • 2x IIyama Prolite E2473HDS main screens
  • Samsung UE22ES5400 optional third screen connected by HDMI (shared with my MSX and a Linux PC)
  • Windows 7 64bit running tools which aren't too heavy, so in fact the computer is overkill to my needs



Work space

This is how the relax corner looks like right now.
