Any thoughts about selling my 33mhz turbo 040??

[jimjimx]

I'd like to use it with my SE/30, but the $250 adaptor is just too much…..

If I found a cheap Iici, IIsi, IIvx, IIvx, i could plug it in right away...

And, I have the adaptor for the Iix, which is how I came to own the whole thing….

I'd like to use it…. But it's just sitting there

The only one on the list you mentioned that I know will work without an active adapter would be the IIci. Dunno about the IIvx, but I highly doubt it's compatibility. Have you got an LCIII?

 

[jimjimx]

No LCIII. I had a LCII years ago…. I forgot what I traded it for...

I thought I read that it'd work with any of the II series with PDS / Cache slots???

I did have it in a Iici years ago. I'm starting to think that I'd like to make someone else happy with it… Maybe $75 -$100...

Heck, I'll snap it up for that in a heartbeat for my NuBus in SE/30 project.

That aside, is the Turbo 040 part of the Universal PowerCache series? If so, I might have the solution for your dilemma if you're interested at all in keeping it. I'm in the process of refining the toy collection. I fired up the stack of LCs/Quadra 605s from the deepest, darkest, least accessible corner of my closet yesterday. The LCIII fired right up, I'd removed the PowerCache adapter (I bought four of them for parts in Shreve Systems fabled clearance sale) before I tested it  .  .  .

 

[jimjimx]

Will this one work with the LCIII?  This is the one that fits into the cache slot on the Iici, and I have the adaptor for the Iix...

I'll get some pictures up later….

If it's a DayStar Universal PowerCache, you betcha! I figured it must be from your mention of the Artmix board for the SE/30.

System compatibility research summary in the last post: Are there Chips on your PowerCache Adapter? HELP REQUEST

 

[jimjimx]

From what I remember, it does have the same 32k cache as the Iici cache card, but I don't know if it's "Power Cache".

[Trash80toHP_Mini]

Does it say DayStar on the PCB?

 

[jimjimx]

OK here we go….Pix, ant the ROM is 2983, which I believe was 3rd of 4.

at the top of the adaptor, on the underside, it says Single slot Iix adaptor...

[Trash80toHP_Mini]

That's it! Don't care which way it goes, but one of us needs to use that sucker! [] ]'>

 

[jimjimx]

Right….  But where do I get an affordable SE/30 adaptor?

For the price of an Artmix, I might as well buy a Quadra….

[jimjimx]

I'm sure you've seen this before….

… A day after I sell it, I'll find a SE/30 adaptor for $20

--jim

 

[ArmorAlley]

I have an LCIII that you may have for $20 (warning: shipping from Europe!) but how will this card fit inside an LCIII?

 

[Trash80toHP_Mini]

If you find one after the fact, pass that adapter on to me!

If I can finally find just a little help, I've got an SE/30 adapter project in the works. I remember somebody posting who said he was an EE, forgot who it was though. I know techknight's plate is full. At this point, just the pinouts from any single chip IIsi or SE/30 adapter would do for the socket section of my wire wrap prototype.

If you do decide to keep it, I could use parts money a whole lot more than my LCIII/Adapter combo.

 

[jimjimx]

I heard that the IIsi adaptor in a se/30 requires cutting part of the metal frame?

--jim

 

[Trash80toHP_Mini]

Dunno about that, does it even work?

The adapter cloning project is going to be interesting for a while, gotta reverse engineer the three chip Mac II adapter to tease out the IIci cache slot adaptation from discrete 68020 and PMMU pinouts. Hold onto your Universal PowerCache Turbo 040, it'll likely be a long time coming and a fairly long shot, but we may have the Universal PowerCache adapters cloned  .  .  .  eventually.

 

[jimjimx]

Would the Iix adaptor do you any good?

…. Again, as soon as I get rid of it, I'll find a IIx. Ha!

Eh.. I don't think I'd want a IIx. I think I'm going stick to SE/30 that I use for MIDI, with Master Tracks 5.

--jim

 

[Trash80toHP_Mini]

Actually it might help a lot! The IIx has NuBus Slot $E implemented on the MoBo, hence, the little PAL on your adapter board. It's a single chip implementation of a 68030 direct pinout to the IIci cache slot implementation. That should give me the info I need for the wire wrap prototype. Reverse engineering the chip free, passive Mac II adapter will hopefully provide a lot of clues as to the function programmed into that PAL  .  .  .

.  .  .  now I need to figure out how to do a proper schematic.  :-/   Nobody seems to understand the visually oriented, trace based schematics I need to create in order to understand this schiznit.

 

[jimjimx]

i'll send it to ya, if ya promise to give me a discount when ya get the board done… Unless thats $250 too.

Why does artmix charge so much? Is just because of the monopoly?

Why not copy his board.

idunno. I believe in better values, I guess.
