E-mu Emulator Sampler User Forum for the EIII EII EI and EIII XP - Recent Posts

It's mostly pointless to run Alchemy in an emulator other than for nostalgia. 

You need a REAL Motorola powered Macintosh computer, with an RS424 port, and SCSI / MIDI hardware to interface Alchemy with any vintage samplers. 

If you wanna buy a restored classic Mac, and MIDI hardware for your studio, you can contact us, we have lots of options, and they come with a fully authorized version of Alchemy pre-installed.

Cheers!

Reverse engineering is a fools errand.  The IC was made by Rockwell.  A Rockwell R6500/1EAC with some customizations.
But if you wanna buy a replacement, we have several on hand.

email: Sales@Synthesizer.repair    and make sure to include your full name, Eiii serial number, and your daytime phone number.

Cheers!

Yes,  but not for ZULU.   If you have a SCSI2SD, PM!!

Yes.   We have gotten our own PiSCSI version to work. (based on a custom redesign of the original RaSCSI)

If you have original CD's and / or ISO's  or .IMG of Eiii hard drives, you can set the PiSCSI up to work with the Eiii.  The Web-interface also works wonderful. 

However.  If you have CD or Hard drive images in the EMXP format, you might have problems!

This is the issue that I am currently trying to figure out, as I have a large number of CD images that were made with EMXP.  Presently, EMXP does not provide a way to export these images as a standard .ISO, or .IMG.

This is also the same issue with the ZULU SCSI devices.  I hope E-Synthesist will chime and, and maybe have a solution for the community!!

Another update - I was contacted by one guy on FB regarding my success on reading jedec from IC27, and he sent me a jedec for IC10 (Type 16L8, Interrupt/Wait PAL with number IP373) that he was able to read from his EIII.

It`s a great news, we now have only two PALs with missing jedec, hopefully not for long...

Here is an update of the crusade for the CPU board PALs jedec:

I`ve got an access for the EIII that was probably "serviced" by EMU. As you can see on the pic, the IC27 has a sticker with IP374B EMU on it, and guess what - I was able to copy a jedec from it, as you can see on second pic, so it was not "protected". So, there is hope, that it is a possibility to find serviced EIII with replaced ICs on CPU board that is also not protected, and we can copy the JEDEC.
PM me if you need a IC27 jedec and also if you have the same stickers on the CPU board pals on your EIII )

Regards,
Kirill

Hi

As a reply to my own post I ordered a regular S3528 IC from Ebay which solved the problem. No need for a specific AMI 8507mai type of IC.

I know i`ve posted this question a few years ago, but its still relevant for me.
I have a EIII with bad IC32 PAL - and midi out is not working.
I`m still looking for dead EIII to cannibalize or maybe someone have a JEDEC file for it, so I can burn a new one. Any ideas are welcome ) Tnx.

Hi Pierre,

Give the attached version a try. It's from 1993.
So, it predates Mac OS 8. I'm guessing that it'll still work in 8.6.

Yes, unfortunately it seems to be a very, very long shot to have this chip replaced...
I'm curious if it might be a possibility to reverse engineer the IM368/R6500-1 by logging the i/o communication across the pins somehow and using AI to piece together the code for the correct environment with another programmable microcontroller? Perhaps AI aided coding is up to the task?
