Roland MC50 disk image with songs needed

Hi,

I would like to test what signals I get on my FDC when trying to read a valid MC50 disk image.

Is there anyone here who could send me one MC50 .IMG 720kb file that I could write to my floppy using Omnidisk and then try to read on my MC50?

Re: How to tune Korg Micro Preset M500

This is quite an old post, but will see if I can revive it. I finally finished fixing my M500 and now stumbling on how to tune it. My biggest problem is that I am out of range. Vr1 seems to be a secondary VCO tune from keyboard Vr2 tunes the VCO (frequency) Vr3 tunes the trigger, but also affects fr...

I agree with Raputin. His approach makes more sense.

Re: Ensoniq EPS system disk needed.

I would not blame the PSU. Basically because if the voltage changes to a point where it affects the RAM threshold it would affect all other TTL devices, such as CPU and CPU rom, you would experience a system crash. one good thing you could do is to recap the PSU. That is always a good thing. Just a ...

Re: Ensoniq EPS system disk needed.

Hey, based in the EU and currently rehabilitating an EPS from an estate sale that lay in storage for some time here. I've got an extra disk, but due to location might that not be so convenient. There is an eBay seller based in the UK whose disks work for me, if that's of any help. Also curious to a...

Ensoniq EPS system disk needed.

I just finally managed to fix my EPS after months onto it. Ended up replacing some faulty RAM ICs and a faulty disk drive. I managed to get it going with a Gotek-HxC but still curious to see if there is a way to save the original drive. To do that I will need a 100% proven working OS disk. Any good ...

Re: What software is used to write the EPS249OS.hfe image to a floppy?

It was the drive that was faulty. I got a gotek and installed a HxC and it now works fine.

It is sad the old drive does not work anymore.

Ensoniq EPS .HFE file needed

I just fixed my old EPS and added a HxC floppy emulator and need an .HFE image file with a sample in it to test loading a sample and playing it. Could be any sound, it is just for testing and make sure it can load a sample and play it. I tried to use the ones provided by HxC (QuickInstall_FloppyDisk...

Re: What software is used to write the EPS249OS.hfe image to a floppy?

It is a long story with this EPS and I was trying to restore it to factory. Will be wiser to follow your advice and try the GOTEK drive. I found this one on aliexpres. Says it is a GOTEK so I assume that is the right one. I notice there are 720kb and 1.44Mb Gotek drives. Does it make a difference co...

Re: What software is used to write the EPS249OS.hfe image to a floppy?

If you really want to stay with diskettes then you have to verify that your PC drive is in proper alignment or otherwise in proper working order. Easiest way would be to get another similar PC or install another floppy drive into the same PC and do the same test. If both PC drives cannot easily rea...

Re: What software is used to write the EPS249OS.hfe image to a floppy?

I went through several DD disks yesterday and got mixed results. Some disks would crash at 0% others at 70%. Pretty clear some of the 80 sectors were not functional anymore. I could manage to get ONE disk to format 100%, Write 100% and read 100%. Put both original.img and the image retrieved from th...

Re: What software is used to write the EPS249OS.hfe image to a floppy?

You mean the replace the original windows FDC and Floppy drivers with the ones that comes in the package with Omniflop?

If that is it I've done that.
