Are you using a custom cable to connect to the wavetable headers on the card, or something routed over the joystick port? If the header, is it doing both the MIDI signal and audio to/from the sound card?

The SB16 is a CT4180. I soldered a two pin header (data and gnd) to the bottom of the 15-pin joystick port. There's a resistor between the SB16 and MacSD to limit current. The synth uses the same 4-pin audio header as CD audio.

So redbook CD audio is working without issue? Are you able to boot the PCs off a SCSI HDD image and do CD emulation and all that all at once?

CD audio is working without issue. This Gateway 2000 has an Adaptec AHA1520 (with ROM), so MacSD is the boot device. It emulates one CD drive and there is an IDE CDROM in there as well.

This is a DOS 6.22 / Win95 system. CD audio works great in Windows as well.

ok, I might be wrong here, but I don't consider a Vibra16C an SB16, but meh, that aside.

If a soundcard has a wavetable header, connecting that to the macsd should/could work, right?

Even audio could be routed back through the wavetable header in stead of the cd in , though that is just an added option.

Sure, I don't see why not.

Cool, I've had you bookmarked for over three years now 😒
Guess I should make an order soon-ish. 😁

SETBLASTER, I saw your PM but can't reply for some reason.

Interesting device and well done work @YMK.
So, for us non-SCSI user we need

MacIDE !!

That would be a dream. I would say working CD-Audio is a must-have and no other device offers this yet for IDE.
Correct me if I'm wrong.

Re: Gotek like Optical Driver Emulator - Is it possible?

You might be able to contact the creator through his yt email addr.

Can confirm that it works. oled display and dac module are seperate.

Go to 14:23 in the video for the cd audio demo.

Are you saying the Russian IDE SD emulator was released? The last videos were from two years ago with no information about obtaining it.

I just read the comments under his video.

If tomorrow the 'special military operation' ends, I wouldn't be surprised if the device will be more readily available .
Though I'm just expressing hope since the device from fixel seems to be suffering from logistics problems.
and offcourse the next contender on the market will be the zuluide... 🤞

Check this out: Kevin Moonlight’s Panasonic CD-ROM emulation using a Pi Pico

Thanks @Zeerex, very interesting!
CD-Audio works.

Unfortunalety it's only usable with a Laptop / PCMCIA solution.

Isn't PCMCIA just ISA?

It can be either ISA or PCI. I'm not sure if it's 100% one to one for the pins. But the design should be able to be translated over.

FYI, if it's PCI then it's mostly called CardBus, and the pins aren't one for one, as in the ISA PCMCIA doesn't do DMA, if I recall correctly.

From the video it looks like Panasonic interface uses one two 8 bit IO ports and is pooled. In that case it could even be adopted to work over LPT.

PicoGUS should have no problem adding this functionality.

FYI, open beta zulu-ide cdrom/zip emulator

https://store.rabbitholecomputing.com/ZuluIDE … 040-compact.htm
http://www.zuluide.com/

I'm assuming ZuluIDE wont support things like clonecd images or other disc images with copy protection software?
Also can it play redbook audio?

In description it says:

CD-ROM images are represented by ISO or raw binary .bin/.cue file formats

From what I understand ZuluIDE currently has a limited feature set. The CD Audio code has not been ported over from ZuluSCSI yet.
I ordered one anyway.

I do have several ZuluSCSI with DAC Attack CD Audio addon boards and I am quite happy with them. I have one in every retro PC that has a SCSI controller except for my Macintosh IIci.

I also own a MacSD and CD Audio also worked well on that however I have not used it in a while. The ZuluSCSI comes with a mounting bracket that is imho better suited for PC cases, although it can also be tricky with screw hole locations. I also had at least one SCSI controller that I could not get the MacSD to work with. Another somewhat annoying issue that I had with the MacSD is that it has to reindex the filesystem if there is any fragmentation. Depending on how the device is used this might be a non-issue. But I found it very annoying since I do like to copy files to the SD card quite frequently.

If anyone is looking to buy the IDE Emu from Fixel/Felix, then I have terrible news for you:
https://cohost.org/Ackart/post/6055773-the-chronicles-of-an

In short, Felix kept lying to those who purchased/pre-ordered products from his site. The orders never got shipped and he made a lot of excuses to buy himself time. Eventually, many of the customers asked for refunds.

I am surprised that not too many people are talking about this, the IDE Emu is still available for "purchase" on his site and more people could fall for his scam!
