Accelerators

[Macdrone]

So with a load of macs I got last month or so I got 5 accelerators for macs and have 4 identified I think. So I'll describe them maybe you can shed some light as I can't find any info on them really.

It's a day star digital SE powercache P4 adapter with a ram slot and the crystal says 66.666mhz. It has a pass thru which I think is for the P33 daystar digital universal powercache that I found in the box with it which is a 68030C40B with matching FPU. My question is this for both the SE and SE/30 or am I missing something?

So the next is a Dove computer corp p/n 01082 030 upgrade Mac SE that has to be for the original SE as it snaps right over the processor.

Next says Supermac Technology SN 7007528 part number 0006279-0001 with a 68000P12F chip so I was thinking SE accelerator again as its the first with a slot and the chip is a 68000.

Last is a total systems 32mhz 68030 with full fpu and four ram slots all filled. I found some info on lowendmac that says this is for and LCII, so I guess I'll try it out and see. I have the Connectix software for ram and accelerators so well see if it works out. My question on this is it missing something as there are two rows of pins 32 pins across and U12 chip socket open.

Thanks for any insight. I'll post pictures of each if I can figure that out.

Total Systems made/rebranded many accelerators for different Macs. Four SIMMs on a card from TS sounds like an SE accelerator to me.

Good, clear, large size pics of each board would be what you'll need to provide to get some help in identifying them and then getting them up and running.

i'm not sure why, but i just don't believe this guy,

i would have thought the 68060 would have pounded the 040,

especially running at 75mhz

Turbo 060

I worked at DayStar for a while and wanted to set the record straight regarding the Turbo 060.

At the time, it wasn't clear how well the PowerPC 601 was going to do performance-wise versus the 68060 when running emulated code. So DayStar did both products in parallel: the '060 version of the Turbo 040, and the PowerPro which was a PowerPC 601-based upgrade.

As it turned out, the '060 was no faster than the '040 at comparable clock speeds, so we killed the product. It had nothing to do with Apple "letting us" do it. The Turbo '040 didn't need a license for the ROMs, and neither did the '060.

It is true that Apple really wanted a smooth transition to PowerPC, but they had no control over what we did. The reality was, the product wasn't compelling, so we killed it.

And the rest, as they say, is history.

I work nights so ill be back in the morning to take some good pics and upload. I already have a möbius accelerator with 16 Meg's of ram running in one SE, I have another SE that needs one of these lol and I'm hoping once I recap the 30 one can boost it.

Thanks again all.

SE and SE/30 PDS are completely incompatible. If you line up the Daystar adapter socket with the SuperMac one mentioned below, the physical differences should be clear.

So the next is a Dove computer corp p/n 01082 030 upgrade Mac SE that has to be for the original SE as it snaps right over the processor.

That will probably work on a Plus, assuming that the processor clip still works after all these years. Dove would have made a specific SE version for the SE PDS slot.

Next says Supermac Technology SN 7007528 part number 0006279-0001 with a 68000P12F chip so I was thinking SE accelerator again as its the first with a slot and the chip is a 68000.

That one is unusual. SuperMac never made accelerators of their own design to my knowledge so it will be one created by Levco. A company called Scientific Micro Systems briefly acquired SuperMac and Levco but never made much of them. The companies divorced a few years later.

For whatever reason the site won't let me upload my iPhone pictures, so I posted them on my Facebook page macdrone@hotmail.com. If it won't let you look at the pictures I posted send me an in invite and I'll accept right away. Also if you have any easy upload picture tips I'm open to suggestion. My name is Jason.

I worked at DayStar for a while and wanted to set the record straight regarding the Turbo 060... As it turned out, the '060 was no faster than the '040 at comparable clock speeds, so we killed the product.

But that begs the question: "what is the technical reason WHY the 060 was no faster than the 040 in Daystar's test?"

It is an especially important question when one reflects upon a later post in that same AppleFritter thread...

"Hands down, the 60 MHz m68060 in an Amiga 1200 running ShapeShifter beat the 80 MHz PowerMac 8100 a majority of the time in CPU intensive operations even when running PowerPC native code!"

If the Amiga 1200 comment is true, then such implies that either Daystar's didn't optimize their 060 test board to take full advantage of the 060 features, or something in MacOS at the time wasn't optimized for the 060, resulting in a zero improvement over the 040.

i dont know if the 060 opcodes were the same as the 040? I cant say because I dont know.

if they are different then emulation would have to be run. And that would slow things down.. alot...

But the amiga could have been running native 060. Again im talking out of my ass because i dont know. lol
