. . . need a catchall for documentation so I can daydream about 'em at work. I'm hoping others will jump in with more silly/impractical/improbable and/or seemingly impossible notions for development or entertainment value.

SCSIGRAPHpi and other silly notions . . .

SCSIGRAPHpi©
It's not my fault, MIRKOSOFT is responsible for this one! I got an Orange Pi one recently to try out something waaaay over my head. In mentioning this wonderful peripheral, I got to thinking someone should hang a SCSI interface off somethingorotherPi to do the job of the old ScuzzyGraph II for folks with B&W Compact Macs or any Mac at all.
Bonus points for scaling 640x400 PowerBook video style output into the center of a matte that looks like a Luggable's bezel in 1080p.
edit: I've got a ScuzzyGraph or equivalent in a box somewhere from my PowerBook 100 BookKeeping period, so I don't need one . . . but SCSIGRAPHpi© playtime might be a lot of fun, especially at higher resolutions. The SE and Plus used to speak TPD, now THAT would be fun with the PB100 or a Luggable.

The guy working on The Tiny SCSI Emulator mentioned getting a SCSI video converter box thingy (a SuperMac SuperView) to play with back in January. He may be working on something like this.
That's good news, it his proc similar to mine? The built-in HDMI output and DIO input of Opi jogged something loose upstairs. Another one just popped up in looking at that page. Might capturing SCSI output at a low level to feed the Opi's 1080p VidCap input for massaging (scaling/matting) and playthru on its HDMI output be a better approach?
Maybe build a replica of the ScuzzyGraph's ZFP case as a multiple "slot" SCSI expansion device chassis with SCSI2SD, NIC, Video etc. inside mimicking Second Wave's expansion box and raising the Compact Mac's screen to an ergonomically correct height?
Great idea, though that seems a simple project by comparison.

MAN I would pay top dollar for a Scuzzygraph III ! HDMI would be welcome!
I have never yet seen an actual Scuzzygraph in the wild. Wish I had one!
Awesome project! Don't give up.
The box is a great idea. But that wouldn't be too hard to design. I can model it if that motivates you to do the whole scsigraph thing.

An expansion box that sits under a compact sounds really good! Regarding the Ethernet as a simple project, I guess I over thought it a little bit. Basically, you would need a way to encapsulate the ethernet frames across the SCSI interface, that's probably what a lot of the SCSI to Ethernet adaptors use, dunno though-there might be a better option. I don't have any SCSI NICs, so I can't do any reverse engineering there, I would love to help though!
I sure think a video expansion that natively outputs digital video would be great.

Not my hack. It's above my pay grade. This thread is a catchall/notebook for silly musings (hopefully not just mine).MAN I would pay top dollar for a Scuzzygraph III ! HDMI would be welcome!

Pi(e) is just food for thought. Given my inapplicable skill sets, someone from the Rpi generation needs to hop onto this notion. It's mostly a software tkinda deal anyway. [

I'd love to see a modern implementation of Faralon's EtherWave that plugged into the printer port and provided an external clock to drive the speed of the RS422 port higher. From what I've seen online RS422 can max out at 10Mb/s!
Some time I would like to see a speed comparison between the SCSI to Ethernet and RS422 EtherWave adapters.

That's a great idea, I remember wishing I had one of those to play with back in the day.
Perused the link in my in ScuzzyGraph search and found it was based on the TI TMS3401 Graphics System Processor according to a post the sunhelp forum. Cutting edge stuff back in 1986, the first programmable graphics processor. Datasheet and Application note are still right there on TI's site!
Neat stuff, more to read at work! [] ]'>

Dunno about that, might be a closer race than you think. Macs requiring such have just awful SCSI throughput.
About that ZFP box, it's something I've mentioned in passing in other threads as a standalone project. Anything in a ZFP case on eBay seems to be priced at about $200, so it's a worthwhile endeavor.
Bezels would be a bit wide for most 3D printers, but you might get around that with a clever sectional design. You'd want to have variations with openings for CD/tape etc. The metal box is an easy sheet metal fab if we can't identify a generic switchbox type case of the proper dimensions. It lends itself to short run production.

An adapter to put an external Zip drive into the 5.25" internal form factor would be another great project on the 3D printing front. My recollection (need more coffee) of the ZipMacPlus hack is a bit hazy, but it should be totally reversible and you could conveniently store the case top, front/back bezels-n-bits inside the ZFP box with plenty of room for SCSI2SD etc.
Printed front bezels for the ZFP case hack: on second thought, it'll need to be painted for color matching anyway, so doing it in two dovetailed pieces for filling/sanding will be no problem at all. Full width would be really nice though. Gotta experiment with texturized spray painting, think MicroPopcorn ceiling effects.
edit: don't forget the indent for a filched Rainbow Logo insert. I'd like to have a full width version with paint fill ready (negatively printed) "engraved" lettering saying 13GB/SC next to the Apple indent and the disk access LED opening in the "Snow White Stripe" for one of my 2.5" Savvio server drives.

Sounds cool, I have had some luck with textured spray painting, but I found that it was a little bit rougher, and a little bit less consistent than I wanted, but it was probably the product I was using as well as me. I wish I had the space for a 3D Printer, kinda running out of space as it is though. If I had no need for this thing called "paper" I could easily put one where my laser printer is.
