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…
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 - …

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.…

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 …

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.

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…
