Note: I have a lot of surplus items that will be relisted at lower prices if unsold, but this is definitely not one of them. I have already sold one of these computers for $1,000 and received good feedback for it as you can see, due to the excellent quality and condition as stated, and I have seen many others sell them for $1,500 or $1,700, and even one for $5,200, lowering this below $1,000 would not be sensible. This is an extremely rare collectible in unusually good working condition. Just the base price for the bare computer was $10,000. The extra cards and memory in it were several thousand dollars more at least.

As shown, perfect condition, tested good.

Please note the good feedback I have received for the almost identical computer that I recently sold.

This is the famous and legendary "wicked fast" Apple Macintosh IIfx computer. Probably the most expensive computer they ever made.

This computer has 20 megabytes of RAM!!!

I have probably owned more of these computers than anyone, as they are a part of my company business and I use them professionally.

There was a 20mb IIfx that sold on eBay recently for over $5,200.

This IIfx computer case, which is a very fragile item, is in excellent condition all the way around. It does not have any dings or gouges. All six white rubber feet are properly in place on the bottom, and the two springy thumb tabs at the back are intact and working smoothly and perfectly. All computer case plastic tabs inside and out are in place and unbroken. This is as nice of a IIfx case as I have ever seen.

As you can see from my other eBay auction listings, I am better stocked than anyone in the category of IIfx computer parts. As such, this computer has every single historically correct trim and screw and bracket and fitting on it. Nothing is incorrect and nothing is missing.

When this computer was originally sold 25 years ago, it had a blue and silver color vinyl sticker on the front of the unit to rebrand it to be sold as a $20,000 computer package as part of a $250,000 audio workstation in 1991. I removed the sticker, revealing the original Macintosh IIfx logo and multicolored Apple emblem, and that area of the computer has no yellowing whatsoever. This case has far far less yellowing then most Macintosh computers of a similar vintage, but that one area that is a little more than 1 inch high is completely un-yellowed, it has been covered from heat and light and sunlight for its entire 25 years, so that area is whiter than on any other computer in existence, and the logo is just like factory new. The Retr0brite treatment can be used to fade the yellow around the front of it. On the sides, yellowing is not really noticeable at all.

This was bought at the store in 1991 by the company New England Digital for $10,000, the NuBus RS-422 processor network card (described below) was installed, they put their stickers on it, then put it with a 19" Sony CRT in a black metal stand that looked like R2D2, and sold it as their "Synclavier Macintosh Workstation" for $20,000. I've had dozens of them over the years, because nearly all systems came with them 1990-1992 and I have had more than 50 systems in stock.

Every IIfx computer I have had is in super clean condition because they spent their entire life inside a rubberized metal cage that holds the computer up out of the way.

This has two NuBus cards installed in it:

The video card is a very high end NuBus video card from RasterOps, the Paintboard Prism GT.

The NED MAC422 NuBus RS-422 processor network card is also installed. This is a very, very high end card that cost thousands of dollars in 1991. It is sort of like a Radius Rocket, as it is a single board Macintosh 68000 computer in its own right , with a Motorola MC68000FN10 and a Motorola MC6 8450RC10, along with much RAM and a crystal and a lot of fancy logic and ROMs. But unlike the Radius Rocket, it has a super high end RS-422 transceiver added, which was the whole point of this card. There were five different peripherals, and meant to be more later, that each had the same 68K single board computer card, though sometimes with a different bus connection for a different type of machine, and each one acted like its own end point on a complex very high speed network. Yes, they could have done the same thing with much cheaper hardware, but they liked things to be super exotic. Remember that a very ordinary NED system in 1987 with sampling voices and hard disk recording cost $500,000 when a 1987 Ferrari 328GTS cost $71,000. So this was high end multiplied by about a thousand times.

This system was a backup to my own personal computer that I have used professionally for several years during the 2000s, and I had to pack it up along with many other things and move it from the home to the garage in 2011, and I had to take it out and use it for a few weeks in late 2012. I removed two lithium batteries at that time because I needed them for another identical computer that was being shipped to a client. Today, I have installed 2 new lithium batteries in it, and it started up immediately and everything is working properly.

I was not able to test the floppy drive before making this listing, I assume it may work because I used it professionally and made many many discs for my clients around the world on it, but I would not be surprised if the floppy drive does not work because Macintosh floppy drives rarely work properly. This is not a huge issue because this computer boots from the internal 120 megabyte Apple hard drive, which itself is amazing that it still works properly.

It also has lots and lots of Macintosh applications on the hard drive, including FileMaker Pro, Virex, Office, and Connectix RAM doubler.

This will be very, very carefully packed, in a solid block of foam and double boxed in very well oversized cartons. The shipping will also have insurance for the full purchase price. I lost money on the last one that I shipped due to the insurance cost and weight, I have corrected the shipping cost this time.

I have shipped electronic music machines to customers in 39 countries around the world just in the last 16 years of my 25 years in the international mail order business, so trust that this will be prepared and packaged to arrive safely.
