White Whale: MicroQue LC aka Chonky LC aka WTF is this thing
Posted by: zackl on 2022-12-03 16:18:34
I've been looking for one of these "turn the pizza box into a PRO workstation" for years

So behold - a magnificent abomination of engineering - the MicroQue Macintosh LC!

I am somewhat baffled by what I have here - I can't find a single reference image or article about this other than another thread that identifies the adapter - detectives?

It's a product similar to the MicroMac Power Workstation, DGR LC Max, or DGR MultiMax. Seems to me the adapter was licensed from DGR, then each company made their own expander chassis.

As mentioned in the other thread, I have 3/4 of one. Missing the front bezel and power supply. I think we determined my adapter was identical to yours.

Can I ask where you found yours?

Edit: Your connector on the back answers questions I had on those pins near the front! Looks like toggle switches so you can turn on/off each of the PDS slots.

Re where I found it I honestly don’t remember! It has been in storage for years at this point and I thought it was just the case / shell. Was shocked to see all the innards. LMK if you need pics of anything

Is there two power supplies ?
Posted by: joshc on 2022-12-04 20:52:31
Yeah, with these you get an additional power supply as well as a riser to take more expansion cards.

This one looks a bit odd in that there's no bezels for a CD drive or floppy drive on the front though?

That would be nice, but I think a CD drive bezel was necessarily omitted because there's no room for one, and the lid and bezels of the donor LC are retained and used for the floppy drive(s).

I could see a customized LC lid with a widened cutout for a slot loading CD drive, though, as I think there would be slightly more room to cram it into the second floppy space than there would be in a stock LC (it would block the cooling fan and speaker, and possibly interfere with the logic board).

@CC_333 @joshc Both DGR and MicroMac made a version with a IIvx style bezel, the MultiMax and PowerWorkstation respectively. It had a couple 5.25" drive bays for whatever you wanted.


And a picture that Trash80 scanned showing the DGR Max ... sort of inbetween the the LC Max and MultiMax.

@zackl I wouldn't mind a picture of the other side of the flippy switches so I can see how it's wired. Then I could wire up my own.
Posted by: olePigeon on 2022-12-06 09:21:05
I just realized with the DGR Max did. It converted the original floppy drive area into the second power supply, then added LED activity indicator bezel that slotted into the original floppy drive opening.

The MicroMac one is the one I was thinking of.

What is the purpose of the flippy switches on the MicroQue?
Posted by: olePigeon on 2022-12-06 10:45:27
@joshc Computers only ever shipped with a single LC PDS slot, and so cards were never designed with the idea of having more than one card on the BUS. There were likely hardware conflicts that came up all the time, so the designers gave you a simple switch with which to enable / disable each slot individually. That way you can swap between cards.

Cool! Thanks for the info, didn't know they had that feature.

I would bet really entertaining things could happen if you flicked those switches while the machine was running.

Given how uncommon this thing is, I wouldn't want to find out....

Hopefully the worst that would happen is a big software crash. Those aren't fun, but at least they're easy enough to recover from.

Fried hardware, not so much.
