I recently bought an E-MU E64 on Ebay, quite cheap (paid 150 euros for it), but the screen was really dim, almost unreadable, so I soon decided to replace it.

After a quick search I came up with this 240x64 LCD Display on Aliexpress for about 25 Euros. It arrived after about 10 days and worked perfectly.

Here's a short guide on how to replace the screen:

I recenly got a second-hand E-mu ESI-32 for cheap, the unit came with a Iomega ZIP drive that was mounted in an external case (NB: it's not the usual "purple" standalone ZIP Drive, which has a d-sub 25 pin connector).
I decided to mount the ZIP Drive internally, replacing the useless Floppy Disk drive, and I also ordered a ZuluSCSI Board to get additional and bigger CD images onto it.

I decided to have them both connected at the same time. The connection is really easy.

If you are using PISCSI with your AKAI Sampler (I highly recommend it!) you can upload any .iso CD image files.
You will be able to attach the CD images  but this will not mount on the AKAI.

In order to make them work with an AKAI sampler, you will need to simply rename them to .hds files (Hard Disk images)

Here's a very simple command I have written to rename ALL .iso files in a folder to .hds, quite handy when you have a big list of files:

for f in *.iso; do mv -- "$f" "${f%.iso}.hds"; done
