S1000 ic11 and ic12 eprom

S1000 ic11 and ic12 eprom

2017-04-25 by mechanicalmatch@...

Hi guys. I am a long time follower of the group, decided to join a while back and start posting. Does anyone have a dump from the eprom ic11 and 12? I know ic9 and ic10 are the O.S. and I have the file for those. Reason I am asking is because I believe these eproms are what makes a s1000 or pb or hd. I have a pb model I would like to try to get it to behave like a s1000 as far as sample editing, just without the inputs.

The diffrence between S1000 and S1000hd is only the SCSI card and internal HD.

As far ad i can remember the s1000hd i had only had two roms...
I suspect that the 4 ROM's listed in the service manual are a red herring. Maybe early models had the is split over 4 ROMs, instead of two. Or maybe early board versions had sockets to install two Rom versions at the same time.

I always thought that the OS for the pb was the same, but detected which unit you have at startup. If you load the latest OS from floppy, what happens?

It would probably take a pretty competent hacker to patch the Rom to enable editing on the S1000pb

Unfortunately we don't have the full schematics for both the s1000 and S1000pb, otherwise it wouldn't be hard to see if there was some simple way of fooling the OS. Of course even if this is possible ,its likely to make the OS crash every time it tries to use hardware functions that are not present.

What you want to do, whilst not impossible, is probably going to be much more hassle that just buying an S1000. If you happened to find schematics for the pb and the S1000, it might be doable though.

Only the internal HDD is.

S-1000, S-1000HD, S-1000PB and S-1100,- all use the same SCSI card and 
that card has an internal SCSI connector in addition to the external 
Centronics-50 connector.

So, you can put a internal HDD (ideally 520MB size max) into any AKAI 
S-series sampler/ sampleplayer w/ the SCSI card built in.
You just only have to decide for the location of that drive and how to 
do it �cause there�s no special HDD mounting-kit existing.
The S-1000 HD already came w/ the drive built in, that�s all.

With latest OS, a AKAI S-1000PB has the same sample- and program editing 
features a S-1000 has,- at least I�m not aware of anything special.
I own 2 S-1100, 1 S-1000 and owned a S-1000PB which I gave to a friend 
some time ago.
IIRC, the difference was, for the S-1000PB the SCSI card was optional 
and it didn�t sample.

All my AKAI samplers use 2 eproms for OS/ firmware.

best

just got in to programming my own  eproms last week ( I got an  emp20) and haven't done much since I took the cover off and programed the eproms. I will reassemble and try and see if I already have what I am searching for. Didn't want to put it all back together and in and out of my rack more than I have too. Thanks for the replies.

I'm not sure how one would utilize the S1000 PB's sample editing features without a data wheel. Using the cursor errors would be a nightmare.

I have a PB unit and found it too cumbersome to use other than an addition to my other S samplers for extra outputs.
