Sequences are saved separately - check out the Seq Save button - when you've got
a sequence you want to save press that button, a digit from 1-9 and enter. 
Saved.   I'll let you figure out we Seq Load button.

another update..
I ended up extracting the DSK-1 eprom and burning a regular i2732A eeprom and it
did not work either. tried with the shugart drive instead of the panasonic, no
go.. so, the question is, could the WD177, 7406 & 7407 be bad? anyone has
prints? to verify the signal path?

I feel I'm narrowing it down
thanks

This panasonic drive is not even the same as my drive in the DSK-1 so I ended up
borrowing the drive from my DSK-1 and it didn't work either. so, I suspect my
problem may be hardware either the FDD interface (WD177) or perhaps the eprom
firmware is buggered up?? I'll have to try burning another eprom, but those OTP
2732 may be hard to find. My shugart drive may be good afterall.

This panasonic drive has the following jumpers
DR,DC,D3,M0,D2,D1,D0,MS,IU and RY is on a separate 4-pin jumper altogether, but the other side of RY is not printed, so no way of knowing what it is, it was originally set in the middle of the 4-pin.
The following are currently jumpered, DC,M0,D0, & RY

Haven't had much time but I'm still in the troubleshooting stages. I've obtained a replacement panasonic drive, that didn't seem to work.
There are extra jumpers on this drive, did not really know how to set them. I ordered a set of new OS disks, waiting for those to arrive.. I did manage to check to Eprom firmware and it is USA+
I'll update when I find the problem.

Sorry for cross-posting this reply to both lists, but I thought maybe
this'd be off some interest while the quest for a possible floppy drive
replacement still continues ;)

> Has there been any progress on the project or did no one reply?

Guess not.. On the slightly off-topic inspirational tip in regard to
floppy-SD adapters, a friend of mine demoed this one on an Amiga 500
last weekend:

http://public.fotki.com/timtashpulatov/11af5/megadrive256/

And there's also some discussion about the board and some variants here
on the Amiga.org forum:

http://www.amiga.org/forums/showthread.php?p=530436

Buttons are used to select a .adf disk image, which is then loaded in to
the SIMM and run. The adapter saves 2Mb MFM image dumps to the SD so it
makes me wonder if this board would possibly work in Mirage as well. As
   a extra bonus there's also the option of installing a piezo buzzer
on-board; this is used to emulate the sound of the drive head stepping :D

.Arto.

Unfortunately I only have OS ver3.2 from the DSK-1. I looked at my DKS-8 board,
it has a 24pin eprom labeled "U.S" according to the bulletin No.8 it should work
with OS ver3. The s/n is actually 11903 and I can tell that it has had upgrade
#1 from the resistor values on the board. Is there any way to find out if its a
compatability issue before I start extracting/burning a new eprom or condemning
the drive? Does anyone have a part number for that 24pin eprom? Would an older
OS say ver1.0 be available somewhere?
Can anyone else boot their DSK-8 with OS ver3.2 ??
thanks

Are there not some hardware mods involved with the upgrade from 2.0 to 3.1? I mean besides changing the firmware.

It's quite possible that the older one has a firmware version too old to
support OS 3.2, but it could just be as simple as blowing a copy of the
newer ROM and sticking that in.

Knackered 4051 multiplexer, or associated TL084 quad opamp.  You can
easily trace out which one does what with a decent oscilloscope and a
note of the pinouts.

Without some working schematics (any idea on where to find them?) I am at a loss

Hey Christian,
Thank you very much and I am going to take your advice simply becuase I don't
want to take any chances with my mirage.
I wanted to clarify that it is not noisy, the sound is barely audible at any
other volume setting besides 100%, right now I have volume at 100% and it is
producing sound as it should.

Most of the time, a noisy volume control is fixed just by moving it back
and forth a few tens of times. The noise mostly come from an oxidized
wiper that didn't move for long, allowing oxidation to build up between
the metal bar beside the carbon pad and the wiper inside the pot. It
rarely comes from the carbon pad itself unless some liquid as spilled
inside or in a extremely dusty environment. Shooting cleaner is rarely a
good idea unless absolutely necessary. Most pots are lubricated with a
grease that is heavy enough to stay away from the carbon pad. If you
pray the pot with a solvent (cleaner), the grease could get dissolved
and contaminate the carbon pad. The pot will stop noising first but
after a few mounts, it could get back noisy and sometimes worst.

What I suggest is play with the volume back & forth all the way for
about 20 or 30 times. If it get less noisy, continue up to about 100
times and it will self clean. If you get no improvement at all, use
cleaner SPARINGLY on the carbon pad ONLY.

Randomly mirage sound disappears producing a faint weak signal that is barely heard and I would move the volume slider up and sound to get it to come back but it stays weak however when I have mirage volume at 100% bringing volume of pa system up the signal is strong as it should be. I am thinking the volume slider needs to be cleaned/sprayed with a safe cleaner that is ok to use on my mirage. What cleaner is safe?

What is the procedure to hardwire volume to 75%?

Any good-quality switch cleaner should do it.  Be careful not to get it
on the front panel, as it can attack certain plastics - use the little
tube thing.

Alternatively just hardwire the thing to be permanently at 75% volume,
like my JX-8P ;-)

That's safe! But it does not remove magnetic particles that have maybe
tricked to the heads and there is almost certainly some... Air is good
to clean dry dust that deposit by natural convection. But when there is
friction like between disk surface and the head, particles that get off
the disks, tend to deposit and stick on the head. What I recommend is a
tape recorder head cleaning solution. Expensive and efficient if you rub
enough. isopropilic alcohol is good too and a lot cheaper. Finally,
acetone is the best but you must be careful to avoid plastics. It melt
about any common plastics except Nylon.

Compressed air?... Avoid air hoses used in service stations, machine
shop or any kind of factory that use compressed air to activate powered
tools. Those systems add oil to the air to lubricate tools and I thing
it's not a good idea to spray oil everywhere in your drive. There is a
risk to get a more dirty drive after this operation. So if you use
compressed air, make sure no oil is mixed in the air distribution
system. To make sure about that, use canned air. More costly but safer.

Good luck!

My drive was malfunctioning a few years ago and all it took was some TLC. All I
did was to remove the drive from unit and with something like a long Q-tip, I
removed the accumulated fuzz. When i compressed it together, it was the size of
a golf ball. Haven't had any drive problems since.

Good luck.

Compressed air?... Avoid air hoses used in service stations, machine
shop or any kind of factory that use compressed air to activate powered
tools. Those systems add oil to the air to lubricate tools and I thing
it's not a good idea to spray oil everywhere in your drive. There is a
risk to get a more dirty drive after this operation. So if you use
compressed air, make sure no oil is mixed in the air distribution
system. To make sure about that, use canned air. More costly but safer.

Good luck!

Remove the drive and clean it with compressed air.

For the one with poor audio, check the output of each filter IC. If
it's not there, check the filter input. If you still don't have it,
check the 4051 MUX (can't remember the number, you can find the circuit
diagrams online) that splits the DOC output or one of the TL084 opamps.

For all voices to fail it would need to be either one of the 4051
eight-way MUXes or 4052/4053 analogue switches that switch between
record and play.
