030 powered 512k, thoughts on maker?

[unity]

I can not seem to find any markings on this one. The only "branding" I found was on the SCSI interface board "© 1989 NSI". But its an 030 and the crystal is for 25Mhz with 4MB of RAM. So this appears to be a pretty big upgrade for a 512k. No clue if it would work on a 128k. It only interfaces with the 68000 and taps into the logic cable presumably for some extra power. It can be removed since it attached with the solder-on pin type connection. There are no case labels to indicate upgrade was performed.

So...how fast is it? 

 

[unity]

I assume 25Mhz until I can find a way to clock it. The CPU has its speed rating removed. So I can only go by the crystal for now.

Woah! Can you socket an FPU in that baby?

You'd certainly have a good 512k...

That same upgrade is shown here, still no mention of who made it though. https://68kmla.org/forums/index.php?/topic/23456-512k-hyperdrive-gamble-on-ebay/?p=243335

Interesting, that one is on a Plus. Mine has a SCSI card that connects to it for an external port. Maybe technight has since figured out more. Over the weekend I will get some better pics and take a much closer look at it. I wish it was KILLY clipped, would make it easier to try out on other boards.

With component revision levels labeled like that, I'm thinking it's a late prototype/development board. The only thing that looks stock is the warranty seal, but placement makes it look like a joke to me. Note the hand written "D" on the cx14/14 label.

Someone in the Monterey, CA area is selling a 128k with a "Gemini" 020/030 processor upgrade -- there aren't any pictures of the inside, but I guess there was at least one company called "Gemini" that made such an upgrade?

I know of Gemini, but not sure if this is one. I have a Gemini upgrade in a Classic. I dont *think* they made anything for the 128 to Plus but could be wrong. I think the SE and up is where Gemini concentrated.

Im not sure about the prototyping thing, I have two other accelerators for the SE that are labeled in a similar fashion. I think the chips are custom ICs or something, not sure. Or because of engineering paranoia, some companies scratch off the actual chip part number then use their own labeling. That was it take a lot more work to figure out the board and copy it. A practice like that is not common anymore.

Well since this is the 3rd thread thats been brought up with this particular accelerator including mine, I will say this. IT DOES work in the plus, but it only identifies itself as an 020, and of course the RAM isnt accessible. Likely because there is no DeclROM, so there is a special driver needed. Also, System 7 hangs on shutdown with this accelerator as well. 

Otherwise it works. 

Now, this accelerator was found in my "hyperdrive 2000" labled plus but there was no signs of the drive left inside, However, that accelerator was inside! and along with the cabling to hook the accelerator up to the power supply, so that accelerator was installed alongside the hyperdrive.

Novy Quick30Plus

Had a hunch it might be a NewLife Accelerator:

Found some neat info and also found this gem which proved me wrong:

Sweet! Thanks much for the detective work. And Novy make sense, they seem to make a lot of accelerators for the compacts, yet never label their dang boards with a name! Ugh! I'll have to do some more reading for sure. Thanks again!

 

[Trash80toHP_Mini]

De nada! Love this schiznit! [] ]'>

Random curiosity strikes again. Spec the wrong thing and turn up what you really need  .  .  .  first page  .  .  .  go figure! :

Now you folks can try drumming up some drivers for your boards.

 

[unity]

I also see that the Total Gemini Classic is the thing in my Classic - has a separate power supply. Weird bugger, but that one I knew was a Gemini of sorts because of case label. Just not sure which one. I will have to do more reading on the other accelerators I have.

 

[Trash80toHP_Mini]

Looks like you need Compact Virtual 3.0 to access 15.5MB of SIMMs (or so) as a Silicon Disk under VM.  [] ]'>

The Novy I just got is labeled:

Nice stuff! Now if your driver disk is universal, we're talking major breakthrough on the Quick30Plus front. Hoping the "Plus" part refers only to the expansion connector, that's be about perfect for getting the basic card up and running. I'm assuming yours is a later iteration of the line. In that case you just might have a full set of drivers. Is Compact Virtual on the disk?

< crosses fingers >

 

[Bolle]

Compact Virtual is not on there. Driver version is 5.35 and it seems it is just an older version of what you can get here: http://vintageapple.org/macdrivers/accel.shtml

What is on my floppy:

-Systech Control Panel

-SystechInit

-an init that patches sound issues

-SmartCache Software

-RamDisk+

I did not yet come around to install Compact Virtual to see if it gets me anywhere. I also have yet to check the exact contents of what drivers are installed on the HD that came with the SE.

I can attach an image of the driver floppy here but I am not quite sure if this complies with the rules or not.

 

[Bolle]

IT DOES work in the plus, but it only identifies itself as an 020, and of course the RAM isnt accessible.

Just checked with the Total Systems Mercury 030 in my SE. It identifies as a 020 as well without any drivers installed. As soon as I installed the drivers from the floppy that came with the Novy accelerator it is seen as a 030 and the extra RAM also shows up as a RAM disk.

Now if I had Compact Virtual installed, I could use this RAM disk for virtual memory and would be able to use the additional RAM beyond the 4MB barrier.
