I want to do this...

[MinerAl]

I found a bin of old parts (including the rest of my ZipCC, so I may get it back in running condition) and in it was a spare CC loom! Woohooo!

That means I just have to isolate the signals from leads: 8 (Video GND), 9 (Comp-Sync), 11 ( B) , 13 (G), 15 ®, 20, 24, 25 (IDs), and 28, 29, 30, & 31 (audio L, L-GND, R, & R-GND). It would be cool to make a little slide-in edge board, but I think I'll just carefully strip out those leads from the ribbon cable and be done with it.

I might actually have something working soon if I can get some time away from family over the Christmas break.

I still have some sanding, painting, and door fitting to do with the body, but except for the monitor connector that jt has, I have assembled all the internal parts.

Looks like I need to send you a care package then. Was that something you sent me or that board from a RoadApple that I offered as a solution? You've totally lost me on this by now. [] ]'>

How on earth could you not keep up? I've only taken a year and 14 different end-goals!

I really just need the cable that has the HD-15M to little-white-single-row-6-position-F-Molexy-thing. The cable itself is black and about 4'-6' long.

The close-to-final internal roadmap is:

* Classic II front-plastics modified to 1993-4 "pout" asthetic

* LC-575 (full 040) LoBo with LC-slot Ethernet card

* Classic II metal chassis

* 575 back door, cut down to fit custom doorway in back of CII bucket

* 9" grayscale SVGA monitor with its own analog board/power supply

* LC power supply for LoBo and HDD

* Color Classic loom/connector

* CII analog board stripped of all electronics except power-plug and main switch, power distributed from these to LC and monitor's power supplies

* split audio and video signals off of (and power onto) the CC loom, send video to monitor, and audio to two original CC style speakers

* notch the CII metal chassis to hold the main connector in the right place for CC style slide-in-action (and do not notch it to make comm-slot useable)

* CC_333 is stripping components off the CII analog board as we speak, intend to mount the HDD to the big blank silicon surface

* find a nice way to securely mount the monitor's analog board under the CRT and above the LC power supply/FDD shelf (its wiring forces this location)

* cut out a full opening for the speaker in the empty CII analog board for left speaker and create a support of some kind (erector set?) for the right speaker.

* unsolder and bridge the power switch on the monitor's analog board (or not. this would be a finishing touch type thing)

There's all kinds of detail I can't predict very well too.

Still kind of like the idea of the KVM switch inside, but that's a Phase II goal I love the idea of having a HD-15F video in hiding behind the monitor adjustment cover on the bucket, but again: Phase II.

Well, I was supposed to be following it closely to try to give you a hand. :lol: You lost me on your detour into uncharted CC territory. :-/

Is that for an extension cable? I thought you needed the cable with the little circuit board that plugs into the MoBo. If you don't have that one, you'll be needing one of my several Road Apple 6XXX Video Out assemblies, IIRC.

Cool beans though. I can try to get something out today, as I won't be back until after Christmas. Your little KVM is sitting happily in the Classic shell that mcd donated to our efforts along with the rest of the stuff you sent along.

It all depends upon when I can walk over and pick up the car, it's getting a high mileage oil change ATM. PM me your address again just in case. I can send your DOA MoBo back at the same time. I guess I could send it out from Philly on Monday as well, today's slipping away fairly quickly.

 

[MinerAl]

Glacially moving forward.

[attachment=0]inside.png[/attachment]

I traded CC_333 all the components on the Classic II's analog board for the naked board itself back. The only things he left me were the power plug and the switch, so they will be mounted in the correct positions. The bare area gives me a nice place to mount the HDD since there isn't enough room on the FDD's shelf for it and the LC power supply AND the "analog board" of the 10" SVGA mono monitor that's going above all this.

You can see the LC PS's wires/plug dangling next to the wires I'll splice it to on the Color Classic loom/connector/thinggy. I need to look into which colors signify what on each, so I don't ruin everything.

The ribbon cable sticking out the front is the one I detailed and diagrammed on the previous page that I will be stripping to isolate and use the R/G/B/sync/L & R audio/ground signals from. I would love to make a little daughter board that'd slide into the connector so I could preserve everything, but this project is long enough in the tooth as-is.

jt: I shouldn't need the video board you mention, and since it is for 580/63X/5XXX/6XXX logic boards, it probably wouldn't work with this 575 lobo anyway. As I said, that ribbon cable sticking out the front has the video signals in it, I just need to get them out and into that cord (shortened considerably) which goes straight to the monitor's AB.

Separate post, because the other is TL;DR.

The LC power supply supplies one +5V, one +12V, two GND, and a -5V.

The CC loom uses two +5V, one +12V, two GND and no -5V at all.

So, two questions:

1) is it okay to supply both +5Vs to the CC loom with the one +5V from the LC PS?

2) is it a problem to have the LC PS's -5V with no load, since it has nothing to connect to on the CC Loom?

My assumption has been that without a monitor to worry about, the LC PS would be plenty to supply the 575 lobo, and HDD and FDD. Bad assumption? (okay, three questions)

Why aren't you using one of the cute, little, adapted SCA drives underneath the FDD? :?:

Please take a set of higher resolution shots of the chassis with all the parts (sans monitor) from every angle. I'm sure I'm not the only one who is lost on what you're doing.

Take a shot of the termination connector of the Monitor, I'm betting you can do your adaptation handily on one of CrapShack's little prototyping boards.

I'm glad you posted, I forgot all about sending that little cable back to you. :I

My silly idea of only using period tech. The SCA drive would totally fit though.

That would be awesome, but the leads are as close together as the wires on a HDD cable, and have to line up perfectly. It would be pretty cool though...

Then stick one in there anyway (power budget permitting) to go with the period drive, that way you can have bootable partitions with every OS that'll run on the cute lil' sucker and room all the programs you wish and for every game ever coded for each OS. [] ]'>

Be sure to do edits to your post every half hour and the one hour edit window will remain open, that way you don't need to rush you photo session.

Is that an "I still need it" or an "I worked my way around the need for it already" good buddy? :?:

 

[MinerAl]

More Pics.

[attachment=0]QCmockup6.png[/attachment]

Yeah, I still need it. The wink was: an ulterior motive for the post was to jog a memory

 

[Trash80toHP_Mini]

Got it! I meant a pic of the connection to the monitor, not the mess connected to the mobo.

It looks to me like you can fit a 6100 PSU in there if you need more power. Got a pic of the bucket's I/O port hackage?

What's the reason for .png instead of .jpg?

edit: got a pic of the loom and the frogeye diagram linkage?

Silly question: since that loom cable is standard IDC cable, why aren't you just crimping and IDC header female connector(s) to it and connecting that to headers installed that CrapShack board?

Because I'm dumb. ) Didn't think of it, but it's pretty obvious now. Thanks! It's even a 40-lead cable, so a common IDE 40-pin head will be perfect. There's one problem partially solved!

I'll try the LC PS first, but the 610 is a good candidate! I'll have to look up dimensions...

PNG is what photoshop was set to when I was doing pic editing fast to make it within the phpBB Edit time window.

Frogeye and the monitor's 6-pin molexy connector the pinouts and other pics are on page 5 of this thread.

 

[Trash80toHP_Mini]

How dumb can you be if you've been bouncing your notions off an idiot like me? :lol:

phpBB edit window jacks up an additional window unit every time you edit. You can keep it open all day long AFAIK.

Hardwire the CrapShack conversion board to the soldertails of that Molexy connector at just the right distance for it to be handy. Plug your new loom connector onto the headers of the Adapter PCB at that spot you determine is handiest. That will make the connection secure, leave the monitor's Molexy shrouded Male connector, its shrouded Female counterpart and her cable untouched. It will make plugging and unplugging the modules very convenient. The power P&G lines will be convenient on the PCB for a hardwire to connector adaptation as well.

edit: no need for research: 6100 PSU = 2.5" High x 4" Wide x 8 7/8" Deep x 11.6A @ +5V x 2.5A @ +12V x 0.5A @ -12V

 

[MinerAl]

Too big I could do 4" or 8 7/8" but not both.

 

[Trash80toHP_Mini]

Would taking the sheet metal off it help? }

You can always toss in a second LC PSU to power your peripherals, up to and including that Power Hungry lil' Savvio under the FDD.

.jpg files aren't necessarily smaller in file size, and also lose quality compared to .png files.

 

[Trash80toHP_Mini]

Interesting, does .png support B&W? That might be useful for some of my .AI screenshot images.

 

[markyb86]

It should. In photoshop if you do "Save for web and devices" there are all sorts of options for png, like how many colors to use, if you want dithering or noise, etc.

 

[MinerAl]

Yeah, the reason Photoshop was set to PNG is that's my default setting for internal web stuff at work. Size isn't the primary concern, in that case, so I go for the quality. I guess I could use TIFFs or some other uncompressed bitmap type, but I'd have to use plug-ins for the browsers to view them.

 

[Trash80toHP_Mini]

I'm still angry with Adobe, so I won't use Photoshop, I'll check out GraphicConverter though.

BTW, I've got the next couple of days off to make a trip to the local USPS facility, Al.
