Not me. I liken to myself as the project director.
Is there any progress on this front?

The project engineer is working slowly to improve the brightness output of the C128 VGA adapter (of which 2 prototypes were shown at this year's CommVEx). When the final design is finished, the adapter will not be hand-assembled but mass-produced.
This is something I'm very interested in. Where's the best place to look for info on this project? Does the engineer have a web page, or a forum they use? Or heck, usenet even?
I have not bought one yet but 1 is on my list. I'm hoping the VGA will work on the 128 or a stock Amiga 1200.
The Commodore 128 does not output VGA. It's possible to adapt it, but you have to build a circuit to adapt the 128's RGBI to a format you can feed to an RGB to VGA adapter.
The Amiga 1200 can output VGA by using 'Productivity Mode', but basically no games will run in that mode, and you'll need another monitor to use to put Workbench -into- that mode.

They even have replacement CRT tubes!

There are more Commodore and Amiga parts; just do a Model search for Commodore.
Does anybody know anything about these "calibration disks"--I'm wondering what they are exactly and where I might get one, or if I could use any 5.25" disk and the software--speaking of which, does anyone know where I could find such software in .D64 format? I'm hoping this might help me resurrect my old 1541 drive; probably won't help much in the case of my 1571, but I figure I might as well work on both drives now since the tool set is coming out invariably.
You'll need to buy one. The diskette you use to calibrate the alignment itself has to be properly aligned. If you create an alignment disk with a misaligned drive, all it'll be good for is getting the drive back to the same misaligned point!
I was able to get an alignment disk off ebay not long ago. They don't seem to be very rare.
My 1902 monitor burst into flames today. (Not quite literally - there was a pop, a horrible sizzle, and voluminous smoke poured out of it.) So I came looking for VGA adapter solutions, and found them here, but now I'm wondering:
Is the metal-case C128D sturdy enough to support a 65 pound monitor? The only VGA displays I have around are some very nice 22" CRTs. They have a great picture, but they're mighty heavy!
The 1571 in my 128D wasn't working. I suspect it was the head tensioner spring, because if I open it up and just baaaaarely touched the drive head, it would read. So I got hold of another 1571 drive and put it in the 128D and... it works, sometimes. But it seems to be the same issue. Sometimes I have to open and close the drive a couple of times to get it to read/write.
Is there anyone that can fix these things? I can just see myself haunting ebay for years trying to get one that actually works, piles of dead and semi-working 1571s behind me. :-)
My 128DCR's internal 1571 has given up the ghost. It's a physical issue with the mechanism - the head isn't pressing down on the disk properly. (If I touch the head *just right* as I try to access a disk, it works.)
In trying to adjust the tension spring, I've just made it worse. So I'm wondering, can I take the mechanism from a standard 1571 drive and install it in a 128DCR? I know the DCR has the drive controller on the system board; will the assorted cables from a normal 1571 just plug in?
(I know I could just disable the internal drive and use an external one, but I'm trying to keep the '128D look' intact.)
Is there any way to write a real floppy disk from a .nib image on the 128? I'm trying to make GEOS 128 disks. I have the archive from here, but converting them to .d64 with nibtools on a PC then using CBM Commander to write the .d64 to disk doesn't work. (The boot disk just boot-loops.)
Since nibconv warns that info is lost converting from .nib to .d64, I presume that's causing the issue.
I know it's possible to use the PC to write the .nib files to disk, but I don't have the hardware needed for that.
Edit: Looks like my 128DCR's internal 1571 is going bad, which is why the disks I made didn't work. Still, it'd be nice to have a way to directly write these .nib files when I get it fixed!
Is there a guide to buying and installing JiffyDOS on a 128DCR?
I see that go4retro sells a 'JiffyDOS ROM Overlay IC' with a prewired switch, and several JiffyDOS ROM firmware sets.
I presume I'd need the hardware and the 128DCR ROM set, but how do I program the chip? Do I need an eprom burner?
The JiffyDOS manuals and such I've been able to find are for the 'flat' 128, and the original chips. I've come across mentions that the 128D and DCR need a different procedure, but not what that procedure is.
