External port traces run through the internal one first... except for one or two. I forget which.

My accelerated Apple IIe makes a higher pitched beep, though I believe Applied Engineering made documents available for writing software to be Accelerator Aware.  Ultima V, for exa…

that is funny your external port works.  but the internal one doesn't.    Techknight knows dead scsi traces oh so well.

I would double check polarity on your caps, and then just retouch all the solder points once more, make sure everything is good.

Nope. Open traces.

Yes I connected two different known good drives internally. An 80MB and 350MB. The drives are seen and will boot the system when I put them in an external SCSI enclosure and connec…

Can I assume you tried a different internal drive?

Hello all,  I recently recapped an SE/30 motherboard. I cleaned the board with a toothbrush and soap and hot water, let it dry for a week or more and then replaced the capacitors.…

On the 3400c's lithium battery board, the black wire is the neg lead; red is the pos; the two white wires connect to tabs between the 2nd and 3rd and 3rd and 4th (I think) cells - …

ok. But it isnt going to help i dont think.... Also when I do figure this out, i will have to reprogram the EEPROM to reset the cell counter so it doesnt think its still "dead"

My 2400C battery was gutted by a previous owner, with no hide and a hair of a picture or diagram anywhere on where the wires go.  So, this might be a long shot, but does anyone ha…

Substituting an ATX supply for the MDD supply is very doable, but there are two issues. First, physical fit.  The MDD supply is long and low, not boxy.   With some hunting you can…

I think its a coined name/brand. But honestly it doesnt matter as long as the reflective die is silver, as it reflects full spectrum without much color distortion, Now granted the …

Probably both? The silver ones are probably most similar to commercially-made CDs, which is another (maybe somewhat simplistic) reason why they work with older players and drives.…

And we have one more clean, perfectly functional Color Classic back in the world again after a solid night's work... This is the same machine that looked like it was pulled from a …

techknight said: I use Diamond CD-Rs, they have a silver recording layer. Click to expand... That a brand, or just find one that says it's got the silver layer?

Yep definitely seems like it's not doing it's thang... from memory I can't ever recall hearing the degaussing "thunk" when powering this CC on, yet all my 5xx-series and the other …

I use Diamond CD-Rs, they have a silver recording layer. Thats the only thing that works on early CD drives as the laser power levels are a bit weaker, and adjusting the power leve…

AichEss, yes, they are A2S4000 models. Serial number on the "older one" is D440DH6, and the serial number with the RocketChip is D490TLC or about 50000 away from the other. Both d…

Scrub it down with baking soda and a tooth brush to eliminate the rust. Wear rubber gloves and a a face mask, you do not want the stuff to touch your skin. Wash down with alcohol …

Elfen, the first two versions of the IIc are 4000 model numbers. Neither has the logic board RAM board slot. Versions 3 & 4 are 4100 model numbers and both have the RAM slo…

Clamshell plug is the same, the newer G4 plug isn't. The Duos, 1400, 3400, G3 PowerBooks and Clamshells all shared a plug.

It's been ordered! (Though, to save costs, I only bought 10 CDs.) It should come by the 19th (next Tuesday/Tuesday week). (It's being sent UPS Ground from New York State to Califor…

A brief update: today I had the chance to get it apart. I can't see major damage to the logic board, however the battery acid has destroyed one of the battery contacts and also se…
