Quite unique IIfx on ebay..

Quite unique IIfx on ebay.. Hardware 47 posts Sep 18, 2013 — Dec 7, 2013
I saw this one too, I'm wondering what's driving the interest?

is it the 128mb of hard to find ram? or the Digidesign Samplecell?

Or are IIFX's in nice cosmetic condition just that hard to find now?

8-o

128MB of IIfx RAM = Hen's Teeth

It will be stripped of the digidesign cards and they'll start popping up in a week or three.

how high might this get? or are we not allowed to talk about $$$

The rule is meant to prevent people from making abusive comments about offerings, ridiculing sellers, overpricing, lack of knowledge (intelligence?) etc.

I'll bow to the other mods rulings on this, but we've often speculated about how high auctions might go due to rarity and undeniable worth, like the sub-200 serial no. Apple II auction recently.

whats a digidesign card.

whats a digidesign card.
...I was curious too... so I found a response from 'sky' on this board entry

http://www.gearslutz.com/board/music-computers/368132-digidesign-nubus-cards-90s.html

Is this the answer? http://en.wikipedia.org/wiki/Sound_Tools

Sound Tools was a digital audio workstation released by Digidesign in the late 1980s. Its successor, Pro Tools, is the current industry standard in music production and TV/film audio post production.[citation needed]

It consisted of a NuBus DSP Card (Sound Accelerator II), Digital Interface (DAT I/O), Analog Interface (AD In) and software (Sound Designer II). It was later replaced by Sound Tools II, which utilized an improved DSP Card (Sound Accelerator II/2) and Interface (442 I/O, same as used in the original Pro Tools system).

It provided mono or stereo recording/editing/playback, as well as DSP effects like EQ, Gain Change, and noise reduction. It was initially made for the Macintosh platform with an Atari version available later.

btw, I put in a bid on it...

Always wait until the last 30 seconds to bid. Nobody wins a bidding war except the seller, who needs that? The only reason to bid early is to put the kaibosh on a BIN so nobody can snap it up before you try to snipe it. [}:)] ]'>

I just bid on a monitor. It looks like you can schedule an automatic (last second?) bid through eBay now . . .

. . . more likely it's a bidding war instigation device . . . ::)

You're better off placing a $2000 bid. If you are up against people who want to go beyond their limit, pull the rug out days earlier and then tell them later how much they suck for trying to robo-bid.

:lol: They're just naive and inexperienced. eBay isn't an auction house, it's a betting parlor. Put that $2,000 bid in the last thirty seconds and that's good enough. I bid what I think I really wanna pay and more power to a sniper who wants it more than I do, I'll be disappointed, but not angry.

Nothing makes me laugh more than whining complaints about sniping. If you look at it rationally instead of emotionally, there's no other conclusion to be made about the most efficient process for buying on eBay, IMO.

I'm with CelGen on this one. Put in what you're willing to pay for the item up front. If you win it, great. If not, you've saved that amount of money, instead of getting into the sniping war and finding that you've just used your kids as financing for something unintentionally. Frequently, I get what I've been looking for, at a reasonable price, by doing that.

I agree that the last minute bid with what you want to pay for it (sniping for effect?) is usually the way to go, but sometimes I want the reminders associated with posting a bid (my bid was immediately countered with an autobid and it went up a whole $2 because of me). The bid early thing almost always goes badly (from any that I've participated on), although I have had a few things that I bid early on, forgot about or was unavailable for the end and wound up winning... sometimes you just get lucky and everyone is out watching something else (or doesn't care).

IIRC, CelGen's a sniper. He was making fun of the folks who'll bid an auction up incrementally before it ever gets anywhere near what it'll go for at the end. You'll sometimes see three or four clowns have done that to each other. That's a no-win situation if you get involved.

If you bid early, that's how you get in a war. What do you do when you see that $2,001 bid? Bid just what you're willing to pay at the very end and you won't have the chance to get in a war by having second thoughts and upping the ante when you see someone has outbid you over the course of the auction.

If someone else bids more in the snipe window, so be it, you won't have a time to try to bid a second time so there's no temptation to go overboard/over-budget.

Just my $.02

Last auction I did bid in was for a DEC LA-120 on a government auction site. Set my bid an hour after the listing was up (was in touch with my university so they could tell me when it went up) and watched for four days as one guy kept stuffing bids and eventually gave up at $52.60 and three days before closing. After taxes it was $75 which was over $300 less than any similar LA-120 on ebay.

A chuckle is permitted because the money I saved pays my car insurance for three months or gives me eight tanks of gas or a small stack of university course books and supplies.

Then people can't believe I got it for so cheap. Remember how I mentioned how my Absolutely Apple IIfx system was less than $100 to build? People still can't believe it.

Yeah, that's not how an auction works. That's being an asshole.

No really. It's like budging in line at the box office to buy tickets. You going to stand for that s***? No, you want your Beiber tickets, dammit!

Unlike my government auction site ebay has no incentive to push forward auction times when bids are placed in the last ten seconds. If they did they would miss out on hundreds or thousands of dollars more in item value which they can tax back in fees.

Sniping exists simply because of capitalist greed.

I stopped bidding on ebay years ago.

Eventually you get fed up on bidding $35 on an ED floppy drive, watching the bid sit for days and in the closing seconds a half dozen others blast the price up to $102.51. I've been using the Make an Offer and Buy it Now options since 2008 and between major PC and Mac hauls while living in Vancouver I've run out of reasons to buy more gear on ebay. All you are doing when you go over your budget and snipe is help inflate and bias the value of hardware which can hit very close to home when small chains of second hand stores are looking up hardware prices on ebay (and we've ALL had someone tell us "it was this much on ebay!"). I bet anyone here $1000 that if ebay ran like a REAL auction house (bid in the closing seconds and the listing time is extended ten more seconds, thus defeating snipers) the value of some of our most prized hardware would fall through the floor.

Now now. What was the forum rule about going after other members? ;)

Still cheap currently for what you get. I have a samplcell card but I installed it in an early Nubus PPC (I think I left it in a 7100/66).

There is what looks like a 9 pin VGA card and some kind of SCSI card (probably the board the sample cells connect to for storage).

IIfx in nice condition plus RAM alone should fetch $200+, not sure what the cards go for these days.

Sniping has always annoyed me, never made sense why ebay hasn't included a feature to extend the auction by a few minutes each time a bid comes in within the last few minutes.

I figured if you can't beat em, join em though, and I've been using a sniping service for years. The way the game is set up, that's by far the best way to win. I agree with everything else here, bidding wars early on just drive up the price. Only time I bid early is to put in a lowball to discourage others from doing the same, or if I could take it or leave it, sometimes I do win.

and some kind of SCSI card (probably the board the sample cells connect to for storage).
The presence of that black connector at the far end of the card is almost a sure sign that it's the interface card for a ProTools box.

The box itself is missing from the auction.

To stay off-topic. :p

My eBay technique is to bid the maximum I'm willing to pay as soon as I decide I'm willing to bid. And I come to a firm conclusion on my maximum. If I place the bid, and am immediately outbid, I give up.

Then I ignore the auction until I get the "the auction is over" email.

Makes absolutely certain I don't go over my "max" amount.

I don't care if it goes for $0.01 over my maximum bid, I don't get worked up. It's likely that the other bidder was willing to make it go much higher, and I'm not out to "punish" the other bidder for outbidding me by driving their bid up artificially.

Exactly. Tried being a sniper and wound up overpaying for a bunch of stuff a few years ago.

Sometimes, it's relieving to see the "You have been outbid" message... :-)

Given the context of my posts on the subject, that was clearly a compliment! :lol:

I don't follow that logic. Auctions at places like livestock corrals and Christies run until the the person who wants an item almost the most drops out. Is there any objection to late bidding by knowledgeable participants of such IRL auctions?

Pretty good article about auctions overall, cites emotion based objections to sniping and research on why it's the better strategy on eBay:

The article points out that letting the unwashed masses in on the true value of an auction item early on isn't good strategy.

BIN is my preference, but I'll sometimes throw out an early bid when I think nobody else is looking.

This NuBus Mac video friendly Radius/KDS LCD Monitor being a prime example. Great display for that IIfx with the right card. :D

I thought that connector would be either SCSI II or a box interface, couldn't decide which though. Being a Sound Production workstation, as opposed to a throughput hungry Video Production setup, I guess there's no real need for I/O faster than pathetic 68k SCSI performance. Would that be the case?

Do the extra cards in the box support additional channels? Are those Digidesign Samplecell cards a later version of my Sound Accelerator II or are they sample input only cards?

Continuing the offtopic..

Some interesting thoughts regarding the IIfx.

Since it has 2x 6502 cpus running at 10mHz managing the io devices, and apple never implemented the use of them'in the OS, I have

always wondered; can they be used in other ways using clever programming?

The original 6502 at 1 mHz wasn't that far off from a 68000, reason for this is that performing its fastest instructions only took 2 cycles,

averaging the instruction totals to around 4-5 cycles. 6502 also accessed the memory at every clockcycle. The 68000 took a full 4 cycles to access memory,

and the relatively complex instructions set needed an average of 14-15 cycles/instruction. Running at 8mHz it kept its distance to the 6502s measly 1 , but

clocking 6502 at 10Mhz might change the game (Its 10X the speed of a apple II thats using the same chip as main cpu). Since the 6510 used in Atari and commodore

are a derivative of the 6502, there are loads of programming experience.

And since C64 with only 64Kb memory could do this https://www.youtube.com/watch?v=So-m4NUzKLw (Demo starts around 8min 40s) you don't need a lot

of memory either. Pretty impressive!

My eBay technique is to bid the maximum I'm willing to pay as soon as I decide I'm willing to bid. And I come to a firm conclusion on my maximum. If I place the bid, and am immediately outbid, I give up.
That's why I use Ezsniper. I paste in the item number and my max bid, set and forget. The Ezsniper service puts in a bid for me in the last few seconds of the auction and either I win or I don't. I don't have to be home, I don't even have to leave my computer on. The snipe does cost something like 1% of the final value fee but only if I win. I've been using it since 2005 with good results and unless ebay makes what I would consider a sensible move to combat sniping by extending the auction when late bids come in, I'll continue to use that method.

If someone could find a way to shoehorn some Apple II ROMs onto a Nubus card that could talk with the 6502's, you could have a dual processor zip chip equipped Apple //e inside your Mac IIfx... Imagine playing Rampage on it.

-J

There is space to put Apple II ROMs on a custom ROM SIMM at which point they are accessible by the main CPU. I have no idea how those 6502s are wired up though, they may not be usable unless they can access the system ROM and RAM. There's a lot more to an Apple II than the CPU chip.

Yep, that's very true. Might have to build a hacked version of the Apple IIe card that uses the processors on the motherboard, instead of the one on the card... Not sure how that would be done, or if it's even possible.

-J

Since they're I/O coprocessors, they're likely too embedded into inaccessible niches of the block diagram for use as CPUs of any kind. Dunno, that's just a WAG on my part.

If you're willing to believe Wikipedia,

The IIfx also included two special dedicated processors for sound and serial communications. These I/O chips featured a pair of embedded 6502 CPUs, meaning that this Mac also had the core of two Apple II machines inside it (albeit at 10 MHz rather than the 1 MHz of the Apple II). However the machine's architecture did not expose these CPUs to developers.
Apple said:
The Macintosh IIfx computer has two custom integrated circuits, the I/O Processors (IOPs), that control the SCC and SWIM ICs and the ADB, serial I/O, and AppleTalk. Each IOP has its own built-in microprocessor and its own dedicated RAM, which it can use for DMA data transfers to and from the I/O interface it controls.
The Guide doesn't specifically address the issue of what microprocessor is on the IOP die, but it was common knowledge that they were 6502s. The first reviews of the IIfx in the Mags all mentioned them IIRC.

Found this information:

The I/O Processor (IOP) is an Apple custom IC designed to provide intelligent support for I/O controllers. There are two of these IOP chips in the Macintosh IIfx computer: one for the SWIM and ADB and one for the SCC. The IOP sits between the main processor and the I/O controllers. The features of the IOP include:•A built-in microprocessor (6502 running at 2 MHz)

•A 17-bit timer

•Two DMA controllers: one for each serial I/O channel (only used in the Serial IOP)

•Address and data busses for RAM used by the IOP and host processor

•Two digital I/O ports for controlling the ADB (on the SWIM-ADB IOP)

•32K of external memory of IOP code and data storage

The 68030 communicates with the IOP through a set of control registers in the IOP that are mapped into the main processors' I/O space. The main processor can interrupt the IOP using a bit in one of the control registers, whereas the IOP can interrupt the 68030 by using an interrupt line.

Each IOP has 32K of external RAM that holds the driver and acts as a buffer for the data processed by the processor. The IOP contains a 16-bit auto-incrementing address register and an 8-bit data port that the host processor uses for access to the shared RAM.
