I keep them all. Not counting the bad ones in the SS1 and 2, I have 7. I can send them to you. I don't mind pick up the shipping costs for something small like that. But the $70 that is it going to cost to ship the SS20 to its new home is another matter. alan On 4/27/18 3:33 PM,

You can always send me the dead modules and I'll rebuild them (GlitchWorks == me, my wife sometimes helps with assembly). Whatever you do, don't throw out the dead NVRAMs -- I'll buy them or pay for you to ship them or whatever, they're not making more and they're the only solution that's 100%

The ones from Mouser work well enough in every system that I have used them in. I still get the IDPROM corrupt message on boot on some systems, but it holds the MAC and the systems boot without intervention. I tried to repair a few and botched most of them. I know that I should be using the

Tip on replacement hard drives: you can use a SCA drive with an adapter inside some Sun boxes, or my personal favorite, a Sun "UniDisk" enclosure with a SCA drive inside. SCA drives are really cheap, even for big ones (they go up to 300 GB), and you can still get some of the later production

Don't get the new MK48T02/MK48T08s from Mouser et al, they're not fully compatible. They will retain NVRAM but the clock part is different and you'll get an error on that (system won't autoboot). Rebuild your old NVRAM! I made up some little boards to make the repair cleaner and faster to do (I

Hello, this kind of keyboards was made using small pieces of conductive rubber to close the circuit designed on the PCB. The rubber was an uniform compound, so even with severe usage, i.e. high consumption, the conductivity remained constant. However, in more recent / cheaper products, the rubber

Excuse my long post, but I get excited whenever I can talk about the Model 16. :) I will expound a bit on what was already mentioned. The Model 16 was an engineering marvel. It was released in 1982 in the same form factor as the venerable Model II. It was essentially an upgraded Model II.
