Hi Jim,

I think the Yamaha YIS503II is technically identical to the CX5MII, right? It sure looks the same. Only difference is that it doesn’t come with an SFG-05 sound module.

In that case, it does have a memory mapper, even the 64K model. However, if the ROM utilises the memory mapper, then loading the ROM into RAM, it might overwrite itself after it’s been loaded. In other words, the problem is the way it’s loaded, not the machine. If this is the case, the best solution would be to load it into a MegaFlashROM cartridge (or similar).

Simple memory mapper test. In Basic, type:

out &hff,1

If the machine crashes, it has a memory mapper.

Simple VDP test. In Basic, type:

screen 0
width 80

If the screen switches to a 80-columns display, it has a V9938 built-in.

If both of these tests give the above mentioned results, then you can fairly confidently say the YIS503II is indeed identical to the CX5MII (the machine that I used in my video).

Yeah, it also hangs after 4 seconds in openMSX. But the mouse support works Smile (Briefly!) I didn't find a way to let the program show the title, but the ROM says: "DMS1 Mk2 MIDI RECORDER"

Note that it works now in openMSX 0.12.0 due to the properly implemented YM2148.

dms1guy are you still here? Smile Do you perhaps have any experience with the MIDI Studio Performer Pack? See http://www.msx.org/forum/msx-talk/hardware/jvc-msx-midi-inte...

Sorry Manuel, I have not come across the MIDI Studio Performer

OK, thanks for your response. Did you ever hear of it back in the day?

I'm pretty certain it came out after I left the scene, as the only sequencer available that that time was the Yamaha FM Composer. DMS1 was the second sequencer after FM Composer, followed by DMS2. Everything else came afterwards. This is the first time I have heard of MIDI Studio Performer.

I was mostly talking about the hardware itself. Although the software also looks pretty interesting Smile It seems it was released around 1985/1986 or so...

Anyway, too bad that it doesn't ring a bell. There doesn't seem to be much known about it.

Hi all, sorry about reviving a thread that's almost exactly four years old, but it's the closest I've seen to answering some of my questions.

I've got an original CX5M that's been upgraded with an SFG-05. First off, I can confirm that DMS1 works (or at least starts, I haven't used it in depth) on this configuration. However, I'd really love to stop using cassettes and move to something like MegaFlashRom used in the video linked to above. This way I can load DMSII *and* save to 'disk' (and also use the YRM-501/502 carts which support disks too).

So, would my CX5M be able to do what the CX5MII can do, if I had a MegaFlashRom cart? Or will the 32K and lack of memory mapper be a problem?

(The reason I'm asking is because I want to demonstrate the CX5M at this event I'm organising - http://www.computinghistory.org.uk/det/41952/Synthesized-23-... - where it will get to sit with illustrious company like a Fairlight and a PPG!)

I don’t think it will be a problem… The MSX2-like CX5MII features are not really used by anything afaik. Yamaha upgraded some of its YRM-1xx cartridges in the YRM-5xx series, but afaik that’s relying on the SFG-05 (which got an MBIOS upgrade) and does not need a CX5MII.

Be sure to get the MegaFlashROM with 512K RAM option. You need that for it to work on a 32K MSX1.

Thanks @grauw! So the Megaflashrom can offer me a memory upgrade, floppy emulation *and* the ability to use multiple ROMs? If so, it's definitely worth me giving it a try ...

Just a quick follow up on this - it works perfectly! Thanks for all your help everyone.
