Re: MJ's stuff

My IIsi is pretty snappy with an 8*24*GC and 7.1.

Re: MJ's stuff

I use the IIsi for all my 030 PDS hacking needs, since with the top case off, the PDS slot is easily available.

Re: MJ's stuff

This is the riser that came with the IIsi. Does this add an FPU when I plug it in?

Also, I got this SuperMac thing on ebay and forgot about it when I made an earlier post (I don't sleep much these days). I am not sure what I can do with it, but it just looked interesting and it's got those dual PDS slots.

Re: MJ's stuff

That riser has an FPU on it, the SuperMac one has an open chip holder to add an FPU.

Re: MJ's stuff

The plain jane LC showed up and didn't work. So I took apart the power supply, and, yep, caps. So I got the old ELNA Long Life caps out, following Charles' reference. I cleaned up the board with some Q tips and Iso.

You all weren't kidding when you say these stink like fish.

Re: MJ's stuff

My plan is to recap the logic board. But something vexes me...

What, pray tell, is this monstrosity doing here?  Should I leave this big fatty alone? It's hot glued to that chip under it.

I have a PB180c screen being recapped by a friend now.
The thing was smelling hard like a rotten herring, and I didn't knew it could be the caps. Spent the evening looking everywhere in the room from where that could come from big_smile Was about to blame the cat, but my nose would always lead me to that screen… Funnily the cat didn't liked the smell.

Re: MJ's stuff

Big fatty looks like it's in pretty good shape, actually.

There's gotta be some kind of LC story behind this, as it seems like overkill, but yeah, it looks pretty solid.

Unless someone convinces me otherwise, I will abide by the old schoolyard rules: Don't Fuck with Big Fatty.

The PS smelled just a little funky... but when I hit it with the 670degF soldering iron, MEIN GOTT.  The smell is what I imagine it must be like in one of those Bering Sea fishing boat bunks. big_smile

Re: MJ's stuff

The recapping of the LC power supply went well. The LC booted right up afterwards! Still want to recap it though.

I must've made the gods angry though. I did the same recap on a working LCIII power supply... and now it doesn't work.  roll

Net gain = 0


EDIT: Found the short and readjusted the 270uf 10v cap-- so the LCIII ps works again too. Happy happy~

Re: MJ's stuff

The IIcx adventure is thankfully pretty much over.

I picked up a NOS logic board and was hoping it would show some signs of life when I swapped it in, but it, like its predecessor, did not respond to the addition of power.  Figured it was another good chance to try re-capping.  The first thing I dealt with was the High Res video card. Seemed the easier of the two to deal with, but I added to the level of difficulty by lifting a pad. roll

After getting some help from Uni and others, I got it straightened out. (The issue. Not the cap. It's tres crooked.) smile

Took a couple days off before tackling the IIcx board itself. It went well and I didn't lift any pads or cause any other problems.

It works! I installed 6.0.8. Now I just have to incept jt into loostening his grip on one of Hisssss Preciousssss  Radius Rockets

Re: MJ's stuff

MJ you may have better luck convincing me to give up one of my Rocket's wink
I think I have a plain 25 or 33mhz unit I could let go, I have 2 of them. I really only want to keep the blue board 40mhz ones, those are crazy fast!

Your restoration of a IIcx reminds me I need to get around to restoring mine one day. Its a mess, needs new caps (lost sound) and the PSU needs fixing as well. Its a pretty snappy Mac given the age!

Somehow I did not get an email. Try sending again...

I would be glad to work out a deal.

Any chance you got the last email? It should come from ThinkClassic Mailer. Spam settings might send it to Junk?

Re: MJ's stuff

FYI, you can replace that gigantic cap on the LC with a 47uf 16V cap. That cap was only on early versions of the motherboard and was replaced by a 47uf cap in later board revisions of the LC. I've done the exact same replacement on two of my LCs that originally had that hot glued cap and they worked fine.

Re: MJ's stuff

BTW, you probably already know, but I didn't see any previous mention of it: that "Riser" that came with your IIs with the FPU installed isn't a riser per se, it's the IIsi NuBus Card Adapter. smile

Re: MJ's stuff

Thanks jt! Yeah, I wrongfully dismissed the card when I first got the machine, assuming it was some kind of riser, but have since been set straight. It's even better than my dual PDS slot adapter apparently, which has a gaping hole for an fpu. 

On another note, I just got back from the dump about 45 minutes ago with THIS! I know these are cheap as chips these days, but I've always loved this machine and finding one for the whopping price of $0.00 was too good to pass up.

It works! It's a dualie 800 with 1.5GB, an 80GB and 60GB hard drives, and two video cards (Rage 128 and Rage 128Pro... ick).

I'm tickled. I really do think it's one of the prettiest Macs out there.  Here it is in the trunk of the Superscrew.
