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.

My understanding is that the 53CF96 is not a drop in replacement. Someone posted that the internal registers are fairly different. I haven't dug into the datasheets enough to have first hand knowledge. You are welcome to a few 53C96. I just need to remember to look for them while I'm at...

If that was teh seller I've been watching for a long while, they wanted 50% more for shipping to the USA than the item cost. 30eu for the cards, but 45eu for shipping and no discount for multiple items bought in one purchase. Still, a great card for conversion to Mac use.

Your 3112 card must have one of the three supported Flash chips on board. AM29LV040 is one of them. I can't remember the other two. Macronix something or other and can't even remember the third brand. I only remember the AM part number because I have a sleeve of them sitting here from...

Forgot to mention, it is always helpful to apply solder flux to the joints before these operations.

Others will undoubtedly have other, possibly better methods. When I've removed chips from existing SIMMs what I've done is supported the SIMM an inch or so above the surface in an upside down position -- chips hanging from the bottom. (If you have chips on both sides, beats me. Support...

Need an icon under the "like" button for jealous. Maybe a green meanie.

Extremely lucky. I've been watching them for the past few years. Several years ago, they were in the find in the ditch next to the road category -- or pay enough to make it worth shipping. Not true any more. The AsanteTalk retailed for $100. For the last couple of years the...

@Zane Kaminski ROM Apple part numbers on the Q840AV are 341S0923 and 341S0924. Does the 660AV use the same ROM? If so, I would guess that the chances of success are excellent. I guess they could have programmed in a machine ID branch, but why would they?

I have a gas range/oven from 1969. Not an option for folks who don't have gas in the house. But nothing electric to blow out. The control knobs are all gas valves. Not electrical controls connected to a failure-prone CPU that might or might not agree to operate the range/oven for you...

I've done that many times -- forget to hit "Post reply". I get such a feeling of accomplishment from finishing my thought coherently (I hope) that it never occurs to me that I need to hit the submit button. Or maybe the cat distracts me a critical moment....

Yeah, I've tried paste with no stencil in the past and mostly made a mess. It's made me reluctant to try it with a stencil. I gather that (with stencil) works out better for you? That's a lot of pins to solder by hand, although I expect you'll get into a rhythm and it will go pretty fast...
