Im looking for one of those as well, my Emax lost his memory last week after a cleaning session, very hard to find ZD413 floppies... Sent from an iPhone ... ...
Hey sounds interesting, i got the same version than Mr. Esynthesist but got a lot of programm and exemple i grabed from a v1.0. I would be i interested in...
You mean this one? http://www.eprelectronics.com/store/html/Products/E-mu-Keyboards-PARTS/E-mu-Emax/Power-supply-Emax-Darwi-68.html If this is the right type,...
If I understand correctly, these are special floppies that are basically extinct. I have a fully loaded EMAXII if there is a way to copy EPROMS I can probably...
Hi Everett If you could do that if would be great, how does this process work ? Sent from an iPhone ... [Non-text portions of this message have been removed]...
It is quite simple, and should work if the EmaxII writes this info to the eproms, but it may write it to one of the PALs. The emaxII uses 2-27C64 eproms, I...
I thought these configurations parameters (memory size, calibration settings, ...) are written to the 9306 eeprom instead of the two normal eproms. So I guess...
Must be that eeprom, because on later E4x models, this eeprom is the word that appears and that can be reinitialized from the "secret menu" without that damn...
That makes more sense,I have never heard of the 27C64 being reprogrammed in circuit. If anyone has a 6 or 8 meg machine, and can read the eeprom, send me the...
The 9306 EEPROM also has a bit (or bits) that determine whether the Emax II has stereo or mono sampling capability. So you need to match that as well as the...
I can try to do this, but I'm a little nervous about killing my box. If somebody can do a little more leg work before I crack into the hardware I would feel a...
You need the remove 9306 EEPROM, its a small 8 pin chip soldered to the main board and designated IC24. You will need to desolder this chip to read in your...
I'm curious, but maybe not THAT curious. I can't find those chips anywhere either. It's only an 8 pin DIP though, so I have plenty of those sockets lying...
Sounds very dangerous to perform that desoldering. Maybe we should simply try to enter the Diagnostics submenu 'adjust features' that contains a kind of...
Well, I don't have an Emax 2, but I believe i can safely remove and re- install the 9306 This chip is actually a National Semiconductor 93C06. its current 8 ...
Maybe it's the most stupid idea launched on this board (mea culpa) but I was wondering whether an eeprom programmer can be connected to the 9306 on the Emax-II...
There are clips manufactured for this purpose, actually. My concern would be whether you would get corrupted data in circuit. and if you had a bad one, I would...
It's a relief to hear it's not a stupid idea after all :-) So I googled on "eeprom clip" and yes indeed, there seems to be very handy tools out there (and not...
I see that there are at least 2 "programmed PALs" in each memory board upgrade kit inventory. Does anyone know what these chips are and what information they...
A memory upgrade indeed also required sometimes the replacement of the PAL. But... I think the two most common situations today are: 1/ Someone's Emax-II has...
oooh, I2C eeprom. I just looked about and found the Atmel datasheet for their 93c46, and an old microchip datasheet for their version of the 06/46. If this is...
I am only saying that it might be that you won't get a valid data file out of it due to it being in the board as opposed to being in the IC holder on the...
The PALs are on the expansion board, and they are the same for the 4/6/8 meg upgrades, but the 5/7 meg upgrades use different PALs. I have 2 main boards that I...
I see what you are saying about the pinout, but it looks like there are parts available on ebay for $1 to $7, so its not that expensive to get the real...
Hello all, I have recently joined this group, have lurked a bit, and have been impressed by the technical expertise of all the participants in this group on...
That's only partially right, there are 3 versions of the 93C46 93C46A is 8 bit 93C46B is 16 bit 93C46C is selectable 8/16 bit, and is the only one that...
Hi all I have an Emax II Turbo keyboard which has developed an intermittant fault. Periodically, some of the keys fail to trigger and this has now worsened so...
first thing to do is open the machine a reset all socketed ic then put the machine back to gether and try again the ic chips can work loose or curode use...

Talk to Jammie- he is in UK....I believe and does synth / Emax repair. Regards, Ted On Nov 9, 2009, at 5:06 AM, chevytravelleruk wrote: Hi all I have an Emax...
