DiiMOCache 50mhz Accelerator

[Maconthemove]

Have this card but no 50mhz chip and 50mhz fpu. Is there any way of telling which Mac it fits? Would like to put it in a SE/30. What are the chances of getting working chips?

Got a pic? IIRC the DiiMO '030 fits the SE/30, but we need a photo to confirm.

And here are the chips you need. (No affiliation with seller, just did a search and up they came) Certainly not cheap though.

Good. If it adheres (necessarily) to the realities of Apple's architecture, it has a IIci PDS connector that will plug into the cache slot of a IIci (only) without an adapter. IIsi and SE/30 use the same IIsi '030 PDS' (to IIci PDS or 'cache' slot) adapter. There are specialized 030 PDS adapters for LC, IIcx, &c., &c. In short, it is the adapter that makes it 'fit', by translating from a given Mac's PDS to a IIci's PDS.

Had you asked a week ago, the 50MHz chips would nave been immediately available at considerably less than the price above.

Those chips are not cheap. Will post a picture tomorrow.

You should be able to get the complete accelerator for less then the cost of those chips (the 68030/50 are popular among Amiga accelerator fans, I have a set in my Amiga 1200).

Here are my DiiMO 030 photos and commentary. Everything you wanted to know about the SE/30-compatible DiiMO and where to buy one too.

 

[Maconthemove]

Not the same as mine. No connector on top. Mine looks like a turbo cache card. Did not see commentary

For those of you who are having the same trouble finding my commentary, I shall be more specific. Here is the exact link to the photo with the commentary in question:




INSTRUCTIONS:

1) Click the URL above to load the web page into your web browser.

2) After that page loads, scroll down and look underneath the photo.

3) Under the photo, you will see the text that starts out with: "Clock Speed. It is interesting to note..." That is my "commentary."

5) Now read through all my commentary and toward the end you will see the seller.

Seriously, if many of you reading this have seen my photos but never took time to read the "commentary," you should. The commentary tells you a lot about the photos you are viewing!

Thanks for the info. That Japannese firm has some neat mods for Compacts.

You might get away with a 40MHz set and a pair of heatsinks

/edit/

It is interesting to note that the 68030 and 68882 are both 40MHz chips / clocked them to 50MHz. It is not known if Micromac is simply overclocking lower speed chips or if they secured chips tested by Motorola to work at 50MHz.

And seeing as there's no heatsink on the card, I reckon your chances with heatsinks just went way up.

A 40MHz set could be scavenged from any 40MHz Quadra

Erm....since when was there a Quadra with a 68030? Maybe a very rare prototype?

Ummm...this interested me more

G3/G4 in IIcx/ci, Quadra and Centris case?????

I have a revision A beige G3 that I may pull and try this with my IIci case.

Or these compact upgrades

They actually beat me to one of my ideas sort of. I was going to try gutting one of my Powerbook 150's and putting it in a Plus case, including removing the CRT and finding a way to attach the Powerbook LCD.I already took the measurements and it looks like a PB 1xx LCD would just about make it.

Sleep deprivation is a harsh mistress. Excuse me while I go slap myself around with a rotting halibut.

If the card doesn't say SE/30 or IIsi, it is designed for the IIci PDS. The connectors are identical but incompatible. Plugging a IIci card into an SE/30 or IIsi will ruin the computer, or the card, or both.

If it is for a IIci, there shouldbe an adaptor that you can find.

 

[Unknown_K]

Where can you find a cheap IIsi adapter?

 

[Bunsen]

Nowhere

It's interesting how he was able to re-use the IIci's Power supply for the G3 motherboard.
