Mac MIDI goes to the serial port, not ADB. There are lots of designs out there for making your own interface, or you can hunt one up on ebay for not too many dollars. Forget ProT…

Thanks for reply, thats great news! german is no problem for me neither making my own pcb. Anyway what software do you use with the midi interface, and what hardware do you plug in…

I built two of Mac RS422 to MIDI interface devices using the description given in the c't magazine. This interface works very well (powered from serial port, 1 x MIDI in, 2 x MIDI …

Hi, I´m going to build this project: http://www.electronics.dit.ie/staff/tscarff/Music_technology/8way_drm2/8way_drm2_1.htm It´s an 8-way velocity sensitive Midi drum pad. I wa…

Seems okay to me too... a ][+ is getting to be relatively rare these days. I've seen crappy IIe's sell for more.

The pricing there is reasonable in my opinion. $50 total equates to about £25 and most Apple II gear goes for way more than that here.

All of Herb Johnson's stuff is overpriced. Click to expand... I kinda had that thought too, but it's really odd because he has this note on the Apple II's for sale page: Th…

Last I heard, Apple II prices are starting to get up there. But you're right, the missing keycap is a cosmetic problem at the very least and a functional problem at worst. (IIRC,…

All of Herb Johnson's stuff is overpriced.

Seems high to me. But then again, a quick scan of eBay confirms that astronomical prices for Apple II stuff seem to be the 'in' thing right now. I'd bet someone here would have one…

Take a look at this Apple II, especially the picture, and if anyone here has some estimates as to what it's worth, I would like to know: Apple II Plus #034, one drive disk I…

It needs a SWIM chip too doesn't it? Maybe that chip is gone, but the power is still hooked up, so the floppy drive powers on and starts to read the disk but then nothing is there …

I'm pretty sure that ROM support for those devices was removed after the Rev.A machines. Luckily you can drop a 333MHz CPU module into a Rev.A : - and a bare Rev.A board should no…

I am 99.99% certain these hacks will only work on a 233Mhz Rev A board. Click to expand... Make that 100% on the floppy drive. Maybe there are further hacks that can be done t…

Which reminds me..one of these days I've gotta find a Rev. A iMac somewhere...would be a neat machine to play around with, not to mention that if I keep it original and in good nic…

I am 99.99% certain these hacks will only work on a 233Mhz Rev A board.

From what I gather, 8.6 is the minimum that will run on this iMac, and you say it would need less than 8.6. Does that mean there's no way to get this to work?

^^digging around it looks like the floppy port will only run on systems below 8.6, if the iMac has had the firmware update applied for OS X then that too could be a factor.

Yep, booted into OS 9 and the drive didn't do much except spin and then stop. I also tried inserting a disk before booting and nothing much happened. You would think it would spi…

I assume you're using OS 9 or earlier to try and read the floppy, being as there's no support in OS X

After playing with the drive for a while, I was unable to get it to actually read a disk. It is getting power because it spins for a moment after a disk is inserted, but it seems …

J12: It was actually a common hack back in the day to mount a 20 pin boxed header here and connect a surplus Mac floppy drive to it - worked out cheaper than buying a USB FDD, if y…

I just mounted a connector onto the floppy drive port and tried it. The drive is getting power, it spins when you insert a disk.

I have noticed on an old 333 MHz iMac logic board that there are traces for what appear to be: J12 = Mac floppy drive J11 = CD analog audio J4 = Serial port (Used for IrDA in or…

It has to do with a bad install disc. Thankfully I use only backups so I don't scratch my originals. Click to expand... Thats a very good idea, I have a 9.0 disc here that I go…
