I haven't looked at the specs, but it's probably not a big deal to change out the internal terminator packs with the "proper value" of resistor to create an on-board Black Terminat…

Do you use two (3.1V) or three (4.65V) to replace a 3.6V PRAM battery? Or are you referring to replacing the 4.5V square PRAM batteries as pictured above?

Yes I desperately need one for my IIfx. I'll send you a PM. Tempest

Gottcha. Well I went to work on it today (finally), and the machine is dead. I always kept the computer in sleep mode while I was logged in and the computer was locked, and apparen…

Tempest, Would you be looking for a black terminator? A couple of days ago, I found my old one (got rid of the IIfx some time ago). John

According to the hard drives article (page 120) in December 1990 MacUser, "the Mac IIfx differs from previous Macs in that it requires so-called black terminators with built-in fil…

It would appear that both power supplies are good, and the 3rd power supply that Tempest sent is good as well. This is the one that tested bad before. I'm thinking that the bad c…

I use the AA and AAA lithium which are usually around 1.55 volts when new.

Would I have to solder the wires to the existing battery socket? If I could attach the wires without soldering, that would be better. Click to expand... In the case of machines…

I dont have a problem with buying batteries online, but only from certain trusted places, random google hits and ebay are just too loaded with half battery half led weight for me t…

Do I have to use surface mount capacitors? Or could I use one that's the same rating, but just solder the wires to the pads? My hands shake too much and I have the hardest time t…

I got a brand new SAFT 3.6V lithium online for a good price. My multimeter shows its perfectly good.

Tempest and I made an agreement for him to send me 2 broken Mac II's (one somewhat gutted) in exchange for repair and recap of his IIfx logic board. I basically paid to have the s…

Yeah, recapping is pretty simple, just that there are SO MANY capacitors. I count 13 that I replaced with 47uF tantalums. Also, these are original Mac IIs, so they don't have a R…

Wow, I'd almost be tempted to leave it sealed!

They could go bad sitting on the shelf, but probably not if kept in a cool environment. Good luck with it. LC motherboards are pretty easy to recap, I still have a LC 3 I did if a…

I've had such rotten luck with getting a working LC motherboard, that if this doesn't work, nothing will. I call this a super conquest for me, even at $25. :beige:

Turns out it was a bad HD cable. Replaced it, and it works great. The coolest thing about this is that it's actually a LC II with the official Apple LC 475 upgrade! Thanks everybo…

Hey now that *is* a good idea. I'll dig some of mine out and join you. On a wiki page would be best. And a scan would be preferable to a photo, where possible - but that can be …

Mac II's came with 800K DD. You might want to check the ROM SIMMs if the units do not chime, I have to clean mine in a pair of IIx's to get them working 100%. Recapping mac II's …

You are quite welcome.

Yep, still needed it! That's EXACTLY what I was looking for, thanks a million, 'junky! Go ahead and button'er back up! Great idea posting a picI I'll do that for all the PSUs in …
