External 6100 Adapter has VGA port pointed across the back of the case so Cable is attached for strain relief. (Hot Glue?) No board or case mods necessary. B.O.M. PCB headers (on PCB which insert into HD45) HD-15 PCB mount, soldertail connector Double Face Tape (affixes unit to back of case)...

Spent way too much time playing in Illustrator only to come up with not quite to scale art: Mounting holes for the VGA Connector are a bit closer to the witness lines for mounting tabs which should touch the sides of the connector. There's no way to Still convinced a simple exterior adapter...

I wish someone would sell some flashed ROM replacements? I've got the hot air rework side of things but not the EEPROM reflashing setup. Very interested in your project, especially so since it's targeted for OS9. Ran my QS for many years to run my considerable Graphics/CAD/CAM suite. Had it on...

LOL! :D I do that too. But something that really holds its shape for Mk.1 eyeball assessment of the bends/shapes on the solder side of the board will be helpful. Cardboard's definitely easier to fab the holes for test fitment of the actual connector in the same config. Make up a cardboard...

Great, glad I could get it straightened out for you. @wottle thanks for that info. Yep, not being on the same page in terms of dimensions is problematic. Cardboard is a great idea, that's how I make prototypes for my riser projects, but they're flat, no bends. There's a better approach for...

inside to inside measurement of the bracket is more like 28.mm, not 35mm. At its widest point at the front, where the edges of the sides are stamped outward from what the sides of your bracket would be, it's only about 30.8mm outside to outside. Deleted/reposting pic from above for rough...

Thanks for the graphic! Center to center isn't the concern, width of the holes from outside edge to outside edge relative to inside to inside edge of your part is the issue. I'll do an AI session tonight. ;)

Sorry about that, I have trouble using language to describe things. Visual thinking has its drawbacks. I'll do a graphic later tonight or tomorrow. Just put a caliper on the parts. the circles on your diagram need to be set apart about 29.12mm, outside edge to outside edge. The inside...

@phipli absolutely love your work here, but scale is problematic. Your lug holes will be nearly tangential to the bend lines on the sides. Nuts won't work and I don't think heavy enough metal to tap would be a workable alternative. Too much work even if possible. I'm wondering if the shield...

Excellent, we can ignore pins 8, 9, 10, 18 and 26! That yields plenty of PCB real estate for a thruhole HD-15 I'd think. Might be a tad off center, but we're in business. Sense lines can be generated in VGA conversion if needed. Dedicated red and green ground shields can be had elsewhere and...

It'll be very easy to buzz the connections. Dedicated R/G/B ground lines and any others can be ignored along with the other ground lines can be picked up elsewhere. Gives a decent shot at getting something cobbled together I think?

If nobody has done it yet, I'll pull out and adapter cable from the morass and buzz the connections. If there's physical interference, SMT HD-15 won't work as a substitute, interference would still be there. Worst case scenario would be a low level interface card with an inverted HD-15 on the...

Ungupatchka! :p Just gotta love that beautiful mess. Haven't done the pin count, are those PCI slots? Back on topic, has anyone worked out the footprint for the required pins for this conversion? If they're not splayed out across two adjacent rows, we might interleave the HD-15 connector pins.

You'll want to make the PCB about 50mm deep and about 35mm wide so it reaches the handy bolt down/standoff hole behind at the right edge of the connector. housing . . . ______ ___| . .. 0 | <- standoff/boltdown | . . . . . . . | | . . . . . . . | |_________| <- rear of case

Yer killin' me here guys! :p Just had to pull the 6100 board to see what's going on. There's plenty of clearance for a horizontal PCB with RA HD-15 VGA connector to pop out the back. There's even a handy bolt-down hole right next to the highest IC to be cleared behind the connector. If the IC...

You don't need the vertical members for such a design. Use Right Angle HD-15 connector and build the VGA conversion into your board. Gotta pop the top to flip the switches, but that's easy on the pop-top 6100. A lot of folks want to keep the logic boards intact, some would gladly pony up the...

Since your stated purpose is to pass these machines along to other folks in the community, I think you might well reconsider my suggestion? Some folks might want to keep the mobo cherry, some may want to keep the case cherry and some might want to pony up the bucks to source the real deal...

Dunno if it counts, but I've been using OS9 PPCs for pretty much everything but browsing for many years? Over Christmas/Hanukkah visit the rug rat finally gifted me with his first Mac, a G4 TiBook. G4 machines have been down, so I've been using a Lombard for day to day Graphics Suite and...

I looked into this a loooong time ago for my 6100. What I came up with was a "periscope" PCB. with built in VGA adapter that mounts to the case with double sided tape or Velcro. ***** Never determined the pin spec for the HDI-45 monstrosity on the bottom of the board, likely header rows are...

Thanks! Do any of the ports work, maybe twop of them? Does anyone have a solution for an OS9 card? Gotta be, there's a vid of a TAM fanatic using SATA.
