I'm so jealous...my first computer when I was a kid was a 6100/66 DOS-compatible with that Houdini II card. I kept it all through college, but then stupidly got rid of it about 16 years ago. I remember also attempting to replace the 486 with one of those 133Mhz processor upgrades. I remember...

I'm also in Pittsburgh...still relatively new to this kind of stuff. Well, I mean used these systems when I was a kid, but just recently acquired a bunch of stuff that I'm having fun playing with and restoring.

Thanks. One of these two is interesting in that it has a homebrew 1MB RAM upgrade that my dad had a local guy perform back in the mid-80s. Probably the only one left like it. The same guy provided custom RAM-disk software with the upgrade that makes it a fairly speedy system. Just remember...

I'm thinking about going to Starbucks and plopping one of these down on a table amongst all the laptops and getting my WordStar on :) These both looked like the one on the left before I fixed them up:

So I've had this lot for awhile now and it keeps growing. My dad lives in TX and I'm in PA, so it makes its way up to me a little at a time. I unfortunately haven't cataloged everything, but here's some of what's here. Most things listed as "in-box" are not only in the original box, but also...

Yes, they are. I tore both drives down, cleaned, lubed, and replaced that ejection gear that always strips in these (a process I've now performed on five various Apple 3.5" drives). This SE also had a working 40MB Quantum HD in it, but I replaced that with a BlueSCSI. It was getting cramped...

Well, I punted on repairing this accelerator and put this cleaned and recapped SE back together without it. The logic board was pristine and retrobrighting went well...I think it came out nice: I did order one of these for when I get around to attempting to repair that accelerator board, but...

I removed the caps again (with my new hot tweezers) and looked closer, and there are definitely some questionable/corroded traces near some of the caps: So...rookie mistake :rolleyes:. Sorry for the noise. Looks like I get to learn how to repair traces. Is this the ideal/correct method...

Yes, like I said, I already did some continuity checks on the SIMM slots themselves, so I have a multimeter. It's hard for me to follow traces on a multi-layer board like this to find the termination points to check continuity...and there are just a bunch of them too. Limiting it to traces...

No, I got that initial error after recapping. I never attempted to use this board with the old capacitors since I could see some signs of leakage under a couple of them. So I don't know if the fault existed before I messed with it. I'm pretty confident the board was completely dry each time...

I've reflowed/added-solder to all of the new caps multiple times since that first picture was taken. I suppose I could remove the caps again, clean the pads again, and install new caps. I do find this packaging a little easier to solder. My process for initially soldering the current caps...

I played around with the jumpers. If JP2 isn't closed, I get garbage to the screen, regardless of what other jumpers are closed. This jives with other revisions of this board I've seen that didn't have jumpers and just had JP2 hard-wired...like this one: If JP2 is closed and any other...

I don't see any solder joints that look suspicious, but like you said, they're tiny. I wanted to try to figure out which two SIMM slots it's complaining about, so I booted up the accelerator with no SIMMs installed and got this: After some experimentation, I came up with this mapping: D31 -...

Here's the steps I took with the MultiSpeed accelerator in the SE today: First, I moved all four SIMMs on the accelerator to different slots. My thinking was that if one of the SIMMs was bad, I would get a different range in the error message than "D7 - D0". The error message remained the...

It's the DOCI50-FPU, so the MicroMac site says it's for the IIci. Now if I can just get this MultiSpeed accelerator in the SE working...

Went looking through this large haul of stuff I got from my dad to see if the box for that accelerator was in there. Got excited when I saw a MicroMac box, but "unfortunately" it was a different accelerator...unused and still sealed in the antistatic bag :p There is a IIci in this lot it...

No luck...the only text files in those archives are release notes...no hardware documentation.

There are four identical SIMMs installed, two on the front, and two on the back. Identifying the chips on the SIMMS, each SIMM looks to be 1MB.

Ya, I saw that, but unfortunately none of their product manuals are hosted there :( That was my plan, but I didn't know if those jumpers had to be configured a certain way for running fewer than four SIMMs (similar to the RAM jumper on the SE's main logic board), and I'd hate to still get an...
