Several members have upgraded one or more Kurzweil 1000 series keyboards or modules. Each person may use different chip burners and/or take a slightly different approach. Before you attempt to upgrade your unit, read each approach. The more you know the better success you will probably have.
This is Process Documentation #2: For and alternate process go to upgradeprocess1
You will need to find a source for the PROM/EPROM chips required for your upgrade. Specifications sheets for the various types can be found in the Manuals page. The 'speed' of the chips you purchase may be important so review all the notes regarding the upgrade before you purchase chips. You can find a beginner's discussion about chips, eproms, roms etc at http://www.ustr.net/memory.htm (this will open a new window).
The raw data (zip files) required to burn the chips is in the Chip Data page. Choose the file for your desired upgrade. Note that the 8 (Eight) button boxes have two possible OS chip sets. Details in the Chip Data page.

How to upgrade the Kurzweil K1000 and K1200 modules.
You can upgrade / expand the modules a bit (from SX > SXA) or "all the way". These are the PRO 1-3 modules. Upgrading a bit is wasting time and money, because for the same you can have it all. And on this site only the OS for the PRO's are available.
This is what you are dealing with:
We have 8 button modules (AX, PX, SXA, etc) and 23 button
modules (PRO 1-3).
What can become what:
Each (8 or 23 button) module can become any PRO. BUT if
eproms are soldered and you don't want to unsolder them, you can only
upgrade in the same line. For instance a PX (piano) has to become a PRO
1. The PRO 1 is the piano and more module. If you change all eproms (soldered
or socketed) and OS, you can make any PRO. But I think an 8 button module
cannot become a PRO 3 because the OS cannot handle this. There is also
no OS upgrade available for this.
What do you need:
Eproms. 27c801 or 27c080 for sound. (See information
on the Chip Data page about alternative Sound Roms chips.) You need
27c512 (200 ms or faster) for OS. (Expanders only) Do not mix different
speeds. Eproms can
Just search for the type (like 27c801). Data sheets
for the eproms can be found on the manuals page of this web site.
You need to solder for the eproms (but you don't have to) and for some boards for the JP03/JP04 jumpers. Changing jumpers is needed. Details can be found the upgrade process #1 documentation. Follow the upgrades menu link.
I desoldered eproms because I wanted a PRO 2 and 3 and wasn't patient enough to wait for available modules. If you sure you also want to do this, do it the less difficult way. Because the soldered eproms can not be erased (OTP), don't spare them. Just cut the legs and desolder the legs one by one. Desoldering is the major job. You need a desoldering pump. I hooked it up to my vacuum cleaner. Be careful not to overheat the vacuum cleaner. After that buy sockets for soldering. Soldering with a magnifier and a small soldering device is easy and even fun.
How to program.
I have used a Batupo programmer from Batronix. This is
the "basic" one, but enough for the Kurz. Can be found here.........
After installing and connecting the programmer (Only USB).
The 4 OS eproms from the 8 button units can be re-used (remove the sticker and erase) if you don't want to save them. But 2 of them (U22 and U33) are too small (they are 32k x 8 bit) for the PRO OS, so you need 64k x 8 bit replacements.
Erasing a eprom / chip
The ones with a window (sometimes stickered) can be erased
with an UV eraser. This is a small and cheap box with a UV lamp. The UV
light erases the eprom. A programmer cannot erase our chips. Do not overdo
the erasing. You can damage them. Start by a few minutes and then try
to program. With error "chip is not empty" do some more erasing
by the minute.
