Thanks bunches, trag, that one's on my to be read pile! Ya think maybe I can get my money back from Border's bankruptcy filing? :

I think Protector is my Niven fave.

I would have used the replacement copy of Lucifer's Hammer next to it, but it was too skinny and the original with the rubber banding is too thick . . . :-/

IMHO, the madman of Chaos Manor is, by a fer' piece, the better half . . .

Dr. Dan is my all time science fictional hero, slightly above Lazarus Long and Dominick Flandry . . . though . . . Lady Harrington now! =8-b . . . . . . . .

edit: because of intolerable levels of curiosity, numerous productive bouts with hypo-mania and the ability to maintain a "brain full of incredible amounts of disjointed and useless information" according to my best friend ever and much loved ex, I have no reason to fear the government's taking away of my right to buy/bear firearms! Dr. Dan and Abbie Hoffman were inspiration enough . . . along with growing up on a farm where stumps didn't stand a chance against the Barn's ChemLab! [] ]'>

. . . speaking of the farm. :I

< swerves back on topic >

Meanwhile, back on the Pickle Plantation:





I couldn't get the alignment to work out perfectly w/o digging out a tripod or relocating a very neatly categorized and considerably tall pile of Hackin'Crud off the copystand to show it clearly enough, soooo . . .

In my impenetrable .TXT:

A Zip is about 7mm wider than than a Floppy. So 3.5mm is required for a bare minimum of side to side offset. Add a bit more wiggle room than that, yielding enough slop factor for an unauthorized field modification placing a larger diameter gun tube on this particular data fighting vehicle's firing port to function and you'll find you're choking the A/B's carb by a bit more than 4mm without swappin' out that hardened steel gun mantlet.

So, no joy on the "easy" internal SCSI Drive install route . . . so my way is the high (over the top) way! :approve:

 

[Trash80toHP_Mini]

No CRT grinding today . . . but the Dozuki ate some blue plastic! }

. . . one side appears to be missing from the exExternal Zip Drive . . .



. . . and the disk just fits side to side now, but a bit-o-plexi thickness and a tad more needs to come off the other side of the FDD slot . . .



. . . a small bite will need to be taken out of the chassis right about here to get the Zip Drive fully into battery . . .



. . . and here's another one for my Sci-Fi brother in arms . . .



. . . even if it is a tad shy in the thickness department in its un(re)read state.

I think I'll go to sleep now. ;D

 

[markyb86]

Oh man, once you get your chassis how it needs to be to fit correct, before you button this up, you should paint the metal the same color as that zip disk. :approve:

8-o GAAAAAAAAAAHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! xx(

< . . . fumbling . . . blindly attempts to hit Ctrl/W while unsuccessfully rubbing away hella' green afterimage burned into his retinas with right hand >

 

[markyb86]

LOL.. come on, it's period appropriate! I kid I kid,

sorry for any long term damage caused by Adobe Photoshop "They made me do it!" :approve:

 

[Trash80toHP_Mini]

No harm, no foul . . . the camera flash seems to have evened everything out on the ol' retinas . . .

The Hacksaw, Bulldog AvSnips and File work looks like it's finished . . .



. . . but the drive still won't quite slip into battery . . .

. . . I could do more of the same to deepen the slot . . .



. . . but the Ryoba smells blue plastic meat underneath the Logic Board . . .

. . . definitely don't want a hungry Ryoba roaming the workbench! :O

Check out the blue plastic arm holding the ejection spring where it coincides with the left (top in the pic) side of the FDD top alignment guide. Those two arms need to be a spring's thickness away from the surface of the bezel . . . unless I sculpt away a tad from the thickness of the bezel when they get there.

Sorry, it's tough to see in the pics, but about a half and inch of the Zip's Exoskeleton needs to be removed . . .

. . . but the Ryoba's gonna nip a tad more than that outta' the Zip's belly. }

< . . . wonders about those garish green floaters on the LCD????? >

 

[phreakout]

Alot, but Trash, can you start posting in "I-Can-Haz-Cheezburger" speak? It makes for a more interesting and entertaining on your posts, imho. ) :lol:

73s de Phreakout. :rambo:

 

[Trash80toHP_Mini]

Cheeboogie, cheebogie, cheeeps . . . no Coke! Pesi! ;D

The Ryoba was still napping from its last meal, so I left it undisturbed . . .



The 45 year old X-Acto Razor Saw filled in while the Dozuki marveled at the abilities of its much older stable mate.

Depending upon the height of any given Wood Pulp ePaperback, intermittent faults occurred . . .

. . . interference between the bottom FDD guide and the breaker bow of the Zip Drive became a PITA . . .

. . . so several of its teeth were carefully removed . . . at first . . .



. . . while the beast was field stripped, I documented the need for a sheet metal fix, and managed to get the BullDog AvSnips in the shot as well . . .



. . . so pair of silver pop-rivets will do nicely here . . .

. . . and did the front side view of the conveniently hacksaw friendly 5.25" Twiggy Drive opening, retained right up to the Mac Plus!



. . . trial fittings proved the earlier tooth extraction strategy somewhat wanting . . .

TBDocumented

. . . so a more aggressive teeth breaking session ensued . . .

TBDocumented

. . . to be continued.

_____________________ spoiler alert! ________________________

all the trial and error paid off handsomely, the zip is calling "honey, I'm hooome!" and it's time to document its function if I can just fine the right book to put under there!

 

Meanwhile, planning (idly mulling over available options whilst sipping Thera-Flu) the support structure continues . . .

. . . as well as noodling out the Power/Cooling budget for Zip and screaming 15k SCA HDD . . .

:sleepy:

 

[uniserver]

wow that Green color really makes it POP!

Now all you need to do is saw a 4" hole in the rear, get your self a chrome plated tip, get a bright red type "R" sticker for the side,

sit there and go BUzzzzzzzzzzzzzz OWWWWWwwwwwwww BUzzzzzzz Owwwwwww, while using it, maybe get some NOZ squirters for the top

A must read to appreciate what i have just said ------>

If you get one of those clear acrylic rods used for adjusting the angle of mini blinds, you can use it to direct the activity LED's light somewhere else, maybe coming out from under the chin? Just a thought. (Unless I missed somewhere that its going to go through the paperclip hole or something?)

Awesome work though, carry on. :approve:

 

[Trash80toHP_Mini]

Already ahead of you on that one, plexi light tubes for all three, maybe four power/activity lights for the Zip & HDD.

All will be little rectangular blocks lined up side by side at the back of the bottom of the finger hole about 3mm high so their tops are just shy of being flush with the bottom of the slot or just even with the filed out existing plastic.

Dunno if it'll pan out out, but that's the plan.

Thanks for the encouragement, it's nice to see somebody thinking ahead in here. [] ]'>

I've got a teaser for you: Why would someone consider mounting a CD-ROM sled upside down on the floor of a Plus? ;D

 

[markyb86]

Why would someone consider mounting a CD-ROM sled upside down on the floor of a Plus? ;D

For when you spill your M&M's and don't want to reach for them? You just MacPlow them off of the table?

Reality here though: Would a disc be able to stay in the tray? or are we talking one of those awkward Mark-has-no-knowledge-of-but-may-have-seen-one cartridge CD-Rom drives?

 

[Trash80toHP_Mini]

 

[MinerAl]

Looks great! Now, how will you make the Plus talk to it?

 

[Trash80toHP_Mini]

By taking it over the top, of course! :approve:





I like the notion of making a pair of custom PCBs for each end of the chain. I'll certainly be doing some version of the adapter PCB for the SCSI Controller so I'll have a standard header on that end. Then I'll make another one very similar to the SCA<->50 pin adapters. It'll be DB-25<->50 pin and in alignment with the connector on the HDD mounted below the ZIP.

With the cables slit to make the turns at the MoBo end it should wind up lookin pretty slick and, hopefully, working even better.

In the meantime I'm just gonna leave the friggin' bucket off that ancient POS and use the standard Zip Cable! [}] ]'>

 

[markyb86]

use the standard Zip Cable! [}] ]'>

It's a little early, so my first thought was, leave it open? Just route the cable out the expansion sl.. OH yeah.. nevermind.. )

 

[Trash80toHP_Mini]

Actually, all Compacts, right back to the 128k, came factory equipped with an expansion slot/slot cover . . .

. . . though, most people just used it to hold in all the corrosion, staining and leaking battery acid.

p.s. anybody got the dimensions/comparisons between Zip and Jaz drive openings? [}] ]'>

 

[MinerAl]

Jaz opening : 3 15/16 x 1/2 inches

 

[Trash80toHP_Mini]

Take one guess who found a translucent Blue Zip100/USB whilst rummaging about this evening? :lol:

 

[Bunsen]

I've been on Facebook too much lately I guess. I just reached over to hit the "Like" button on that last entry

Coming along nicely, Trash80!

X-Acto Razor Saw

Oh boy, I need one of those 8-o
