New to me Apple //gs, I think RAM 03 version, with interesting extras. Audio/music production?

Kinda lucked into this. Don't know much about it yet.

I hooked it up at first to the side by side drive I have for my IIe to try it out. I took the little RaspberryPi HDMI card out of the IIe to try out in this machine also. I got that Monitor /// free with the stand at our computer event in Boise!

I have since tried with with my Floppy Emu I have for the IIe and flashed for Apple II stuff. Seems to work great.

The Echo card and unit came with the GS. Borrowed the keyboard (and mouse though I haven't used it yet) from my SE30. It did come with an Apple II joystick!

Can anyone help me learn about battery placement? I have seen most others further over to the left (as we are looking at it in this pic) of the motherboard, more under the battery.

Another shot of the battery. It has been replaced. Not soldered on.

I think this wire goes up on the front of the Echo board to power it. There is another similar connector that is on black wires that look to go to the stock speaker that are also unplugged. And I am getting no sound.

Upgraded RAM.

when I looked up some info on where the clock battery goes, it seems like a lot of them are soldered onto the board further to the left under the power supply. This one appears to be where it is supposed to be. (it is a new battery) So I guess this is a ROM 3?? or Rev 3? As I said, don't know much yet.

Anyway, will be fun to learn about this and try some stuff. I am also pretty interested in creating sound with it, and I understand will need to get a different sound card for stereo. I understand the GS came with the Ensoniq ES5503 DOC chip, and is capable of 32-oscillator wavetable synthesis which could be fun to play with. WRT a stereo sound card, I see something on Joe's Computer Museum, though they may be out of stock at this point. Anyone want to point me in a direction for that aspect?

That is unquestionably a ROM 3 unit. As was previously said - socketed battery, and no pads for the Apple IIe style keboard or numeric keypad. It has 1MB fast RAM on board, and a 256k ROM.

A significant part of the tools for GS/OS are in ROM on this machine, allowing it to boot and run somewhat faster than its ROM 0/ROM 01 counterparts.

Nice find - can I ask what you paid? I recently purchased a ROM 3 unit with a DuoDisk unit for $300... Computer only, no monitor/keyboard/mouse.

There are some minor compatibility issues with certain games with the ROM 3 unit, but it's very minor and nothing to get concerned about.

IIGS units are increasing in value (albeit slowly), and everyone seems to consider the ROM 3 units the most valuable.

It was through my local Boise area vintage computer club and for privacy concerns, I will DM you. :)

Ah that's not necessary, that's your business. Nice catch though, I'm sure you'll have fun with it. I'm slowly putting mine back together (monitor, keyboard, mouse), and I have a Floppy EMU to use with it as well. I'll try and find period correct disk drives for it at some point down the road.

Apple Rescue of Denver was able to sell me the DuoDisk to I/O cable, and I found I had the I/O card for it on hand already. We'll see how that works. I believe the DuoDisk units don't work on the IIGS SmartPort without some modifications.
