Re: The Big Score! Mountain Expansion Chassis!

Sean,

The one for auction has started with the same price I gave for mine.
If no one else jumps in, I may just bid on this one too.

Re: The Big Score! Mountain Expansion Chassis!

MarkO,

LOL

I'm kinda riding the fence on this myself.

I have one, what the hell will I do with two?

This is a "Damned if I don't, Damned if I do" situation.

No one has bid on it yet though.

Re: The Big Score! Mountain Expansion Chassis!

The question is what are you doing with the one you already have...To me this is a useless expensive crude bulky poorly designed unsupported box with several edge connectors and cheap TTL decoder logic. Had the apple2 been better designed like ISA for example this thing would have never been necessary at all!

georgel,

As a wise man once said:

"Beauty is in the eye of the beholder."

Usefulness can be seen the same way.

I am afraid the we will have to agree to disagree.

Marko,

The thought of making a profit has crossed my mind, but

Buy it
Fix it
study it
Use it (eventually)

Is more to my way of thinking.

Re: The Big Score! Mountain Expansion Chassis!

Well, Steven, it is different than the one you have.

IIRc the dip switches were there to enable/disable specific slots. I haven't worked too much back in the day with that model. So I'd have to re-read the manual.

What changes would you have made? All the while keeping the price reasonable and using the technology of the day.

So many things were brilliant, simple, and practical.. about the Apple II series. And these expansion boxes were quite useful for data acquisition back in the day. They're the unsung heros that helped build today's laser and chip fabrication technology.

Re: The Big Score! Mountain Expansion Chassis!

Based on another thread mentioning that there is an Expansion Chassis offered at eBay I just found this thread and wonder if the re-engineering has come to an end and if there are PCBs made already. I like this project and probably like to rebuild this... so if there are PCBs available I'm highly interested in. Otherwise I'm interested in the board files that allow a recreation by a PCB supplier like Seed Studio.

Re: The Big Score! Mountain Expansion Chassis!

tokabln,

I do not remember if we had any discussions about
coming up with a newer version of the Chassis.
I guess I'm going to have to reread the entire thread.

The first thing would have to be schematics of the board I reckon.
The next thing would be to see how many folks would be interested.

Hello tokabln,

i didn't go that far to create PCB files....
In the days when the pages have been made the main target was debuging a system that was only
partionaly functional and no circuit plans where availiable....
so Keatah and me just analyzed the entire system and created the circuitplans....

The cuircuitplans in that days have been created by use of KiCAD.
Unfortunatly then several months later KiCad was forced to remove the
autorouter function from the web resulting from a judical fight between its creator
and his former employing company..... and in that days i planed to make
later PCBs - but due to limits in my financial abilities i dropped that plan...
too expensive... at least to me...

I didn't try to convert that old files to another system.....
but if you give me email by pm, i can send you the former files
from the circuitplan.

the entire plans are also downloadable at the end of the pages as pdf file
from my site:
http://www.appleii-box.de/H054_1_MCEB01.htm
That PDF file was created just to support repair in case of need....

sincerely
speedyG

Re: The Big Score! Mountain Expansion Chassis!

That's right Speedy and Keatah
did all the heavy lifting on this.
For which I am grateful. Smile

The seller for the current one on eBay just raised his Minimum Price to $300.00

I didn't think you could do that after an auction had started,
but I guess you can.
I have never heard of it.

And everyone knows that increasing your price does nothing but increase your chances of selling the product! Smile

Re: The Big Score! Mountain Expansion Chassis!

Looks like it went for $405.00. I am a little surprised, I thought there would be more demand and it would go higher.

If I didn't have so much Apple "clutter" already, I would've jumped on that auction too! Smile

Re: The Big Score! Mountain Expansion Chassis!

I also was surprised that it didn't
go for more.

Guess I'll hold on to mine a bit longer. lol

Re: The Big Score! Mountain Expansion Chassis!

There wasn't a bidding war, and, besides. It is the "because apple" syndrome, it is the Apple branded stuff that goes for inflated prices.

Power Adapter for Mountain Computer Expansion Chassis (Apple II)

Hi- I'm looking for the power adapter for this chassis or a photo of the front and back (assuming there is a spec label) if anyone has one so I can make my own. Thanks!

You can find the manual here.

You can find the manual here.  Unfortunately it does not appear to document what voltage(s) the external transformer outputs.
