Been away for a while but this item seems to still be available. Thank you. However it's about 2200 dollars. I don't want it that much. At least not this year. Maybe later...

Unfortunately not. The SWIM chip is an actual logic chip, not a memory or storage chip. It is not the kind of thing that can be copied and programmed into another blank chip. That said, if someone does a lot of hard work and figures out the logic going on inside the SWIM, it might be...

And when soldering while using magnification keep in mind that your depth perception may be hosed, unless you like the sound of your nose grease sizzling. Just call me Stripes.

Nice. I have a couple of MicroAsantePrints, so I really don't need one, but I'm tempted anyway. New... Shrink wrapped.... Pretty box...

Excellent. Doesn't ship to the USA, but I entered the Item title in the USA Ebay site, and received a dizzying array of results. The exact one you got is available. But then, there are all the other results...

What kind of microscope do you have? We have this white stereoscope at work and I can never remember the name. Nautilaus or Unicorn or Hydra or something. They're fairly pricey though.

That sounds like the direction to go. The question is would Zane rather rig up the hand programmer and program his chips locally, albeit a little tediously, or would he rather ship them back and forth to me (if I can get the DOS software going).

TechKnight posted about rebuilding flybacks either here or on 68kmla. Apparently, even after you get the coils properly wound, which is a major undertaking by itself, there's some process of dipping teh transformer in a pot of hot something or other, sealant or soemthing like that to drive...

The laptop is running WinXP. Is "restart in MS-DOS mode" available in XP? I'll copy the DOS files to a folder on the HD. There's a bunch of stuff about .ini file configuration that I really hope I don't need to know. I'm not at home at the moment, but I could post the DOS folder here...

According to the Device List I found on line, my Needham EMP-30 supports a Phillips and a Signetics 82S123, if I run the DOS software. I'd straight up offer to program the chips for you when you get to that point, but I've never loaded or run the DOS version of the software -- never needed to...

Well, I was assuming that 514256 chip south of the DP83902 was a static RAM, but sure enough, it's a dynamic RAM, so I guess that Asante chip must be at least acting as a memory controller. Except, the large chip on the left is an 80C188 processor, which is a 16 bit processor and I found...

Back when my job intersected with PaRISC HP machines, I saw that they had an internal SCSI 3.5" floppy drive. Might be interesting if one of those could be found.

Fantastic project. Please keep us updated.

Wow. Someone must have told Dalbani what they had, or they're more clueful than many other sellers. Not too many years ago they were selling flybacks for less than $10 each. $8 each, IIRC. Checked my records -- that was back in 2013. Longer ago than I thought. Time flies....

@lobust I have the chips in hand. Two bricks of 330 parts... I pulled four of them out of one of the bricks. Nice to finally find a use, if only for a few of them. Interestingly, while the chips are marked NCR53C96, the label on the brick has an Apple 337S5396 part number on it...

@Kai Robinson I have this one out of the case waiting for me to fix what is probably a voltage regulator issue. Most of the chips look fairly standard and expected -- DP83902, 8530, static RAM, EPROM, and voltage regulator. However, there is an Asante custom chip on there. The full number...

Techknight posted a fairly extensive IWII refurbishment thread on 68kmla some time in the last several years. It probably didn't deal with that specific problem, but there was a lot of great information in there. Quite a bit of board level component replacement and part sourcing.

It is no nuisance if the box is down stairs. I will try to remember to check this evening, after work.

My earlier comment is only relevant when using the Sonnet TSATA firmware.

There are a couple of Flash chips (IIRC) on the bottom of the board between the pin header strips.
