I put my BMOW ROM in there and it started up from the ROM disk no problem, so I think my hunch about the ROM is correct. Max offered to sell me the ROM ICs but I foolishly declined. Time to get those on order!

that is definitely a possibility. I will bring a BMOW ROM in tomorrow and try it out. If that works, are there replacement ROM options? I am planning on putting in DIP sockets anywhere I can with the reloaded board.

So it wasn't chiming at all, so I reflowed everything and a couple of the chips near where the old capacitors were. I have a chime now and it immediately it does chimes of death. This is regardless of RAM configuration. I can repeat with no RAM, four simms in bank A and with 8 simms in A and...

So I have a little collecting beige boxes problem. My dad's first (and my first) computer is a IIcx. He had a processor riser card added to give it a cache slot where he then installed a Mobius Speedster. I still have the IIcx. While reconnecting with this hobby, I decided to recap my old IIci...

@nathall, is it awesome?

About 9 months ago, my wife and I adopted our son. This has been the biggest life change I have experience so far, and I found myself doing an interesting type of nesting. I found myself worried about my son getting online and ruining his brain, so my line of thinking was I'd be better off...

Is this a Mac 512k or does it have more horsepower?

I also have a rominator and floppyemu as well.

I am starting to plan for Christmas, and I want to upgrade my IIci some more. I have more RAM than I need. I have an 040 accelerator on the way, a couple of zuluscsi adapters - 1 internal, 1 external slim for networking and CD images. I am thinking a video card is next, but I know the nubus...

That's pretty cool!

I don't know how to say this - you all are incredibly talented and I am impressed. I was hoping to hear this would be a relatively easy task, and I am happy to know why it hasn't been done yet. Thank you all for the information and contributing to this community!

I think I am understanding this correct - We could re-design a reproduction board for a IIci to have the cache slot and a 030 PDS that could then use the 30Video as referenced and that may be easiest? What would making a clone of the Thunder card look like? On a complete tangent, my other...

I will start by stating - I know this is a stupid request and using any sort of Quadra would be easier, cheaper, or whatever. My late father had a IIcx that was modified with a CPU riser to have a Mobius Speedster with an LC'040 chip on it. Unfortunately, I have lost that accelerator to time...

I think I have an old mac addiction

I finally got my floppyemu so I was able to get speedometer 2.5 on there. I didn't have an 8Mhz baseline, so I put it against my Mac Classic since it has an 8 Mhz Motorola 68000 CPU. The classic scored a 1.01 on CPU and 1.00 on Math and the SE scored a 2.01 on CPU and a 2.01 on Math, so even...

I will have to try the benchmark. I got 7.1 installed and loaded up TattleTech and saw that it was running at 8Mhz still. I will also inspect the board to see if there are any broken joints or leaky caps or something. I wish I could find some more documentation on it to know what exactly I am...

I got the computer and it actually booted but had lines on the screen. After disassembly, I found the battery had burst and there is some corrosion, but it looks repairable. After it dries we will see what cleaning yields.

thanks, i am going to take the $150 gamble and aee where we get. i have always wanted to do a frankenmac!

I have a dead IIcx and a working IIci. I found a Centris 650 online, but the case is destroyed. The pictures show the power light on - is that enough to determine if it has been battery bombed or not?
