I was the first person to select the "ebay" answer. Let me explain:
None of the answers in the 2nd question best describes me. I've never sold any of my TI gear.
However, I am an eBayer, in the sense that I buy a lot of stuff (TI & non-TI stuff) on eBay. If I were to sell that's probably the route I'd take, since it's the most familiar for me.

Why do I have to "marry" the drive to the system?
You may or may not. Depends on which model PS3 you have.
Earlier PS3s link the drive's board to the PS3's motherboard. If you use a drive that is not "married" to the PS3, the PS3 is not able to read any discs.
Sony apparently didn't want end users to replace optical drives.

This thread over at EAB hints at the PCMCIA + 8 MB RAM issue: http://eab.abime.net/showthread.php?t=75172
It's unclear to me if that's what you are seeing though
-
Can you try the CF without the expansion board installed? If it works then I would guess that the issue is with 3.1 and having more than 4 megs of fast ram.
-
Are you running 3.0 or 3.1? How much RAM do you have?
3.1 has issues with the PMCIA device if there's more than 4 (?) megs of RAM on the machine.

Kind of looks like the battery terminal is shorted to itself... I hope that doesn't do any damage when powered on.

I lurk most of the time, but do the ocassional post.

Signed up for it, along with a couple of others (unrelated).

Just saw this article on a (new?) Windows 95 emulator. I haven't tried it myself though.

Hello, the C99 links in the first post seem to be dead.
I did find C99 on whtech.
C99v4 appears to be here: ftp://ftp.whtech.com/programming/c99/C99REL4/
Docs *might* be here, but I'm unsure: ftp://ftp.whtech.com/programming/c99/StarterKit/

There's a "C" section in the first post of the TI development Resources thread:
http://atariage.com/forums/topic/153704-ti-994a-development-resources/page-1
You'll see C99 there, along with some others. The newest being the GCC cross compiler.

When I was a little younger, one of my favorite sources was "Compute!" magazine. They also published some books, one of which is here:
The above link is for a PDF file, but I actually have it in book form. Be sure to post any questions you may have on it.

A cartridge for an expanded console will have only 384k of cpu ram and 16k of vdp available. This will have to be written in 100% assembly language and use bank switching to bank in the cartridge ROM 8k at a time..
Anyone with rs232 or TIPI is going to have 32k memory expansion. I'd target that model.. The old platoterm required 32k as well.
I don't think too many TIs will have 384k. Also I don't think a cart will have to be 100% assembly, I've done one in C and it seems to work.
I do agree though that targeting 32k expansion is probably the way to go.

Nice M@,
That thing is in great shape. Mine doesn't even have a front cover on it, so I have to show the back:

I would guess that RS232 hardware would be hard to obtain as well. You need either a PEB + RS232 card, or a NanoPEB. The former is not shipping friendly, and latter is doesn't come around too often.
Perhaps there is some other configuration that I'm not aware of.

Are you saying that the screen goes blank when you connect one of the red or white RCA audio connectors but not the other? That sounds like a bad cable to me.
Definitely be careful with that. My (similar) cable outputs 12 volts on the white connector.

Before I start cobbling together a Makefile from libti99, has anyone made a generic Makefile for ti99 projects?
-Thom
There are makefiles in the sample projects in the first post of this thread. The sample projects are: hello, hello2, and hello_cpp

I'm envious of those with younger eyes, I simply would never have found the problem. It's actually irritating not being able to tackle projects once taken for granted.
I use a couple of tools to help me work on boards.
One is a USB microscope ($30), which I use for soldering. The only trick is that it doesn't give me 3D vision so it's hard to tell where my soldering iron is sometimes.
The other tool I use is a proper digital camera. I take photos of boards and then view (inspect) the results on my large monitor.
The attached photo is a shot from my microscope. Just to give you a sense of scale, the grey squares on the left are 5 x 5 millimeters each.

Stipulating this is possible, it defeats the digital output spirit of the F18A MK2 and the necessity of its design.
It reduces the footprint of the F18A, and it theoretically allows other signaling. Perhaps it could be done in such a way where you get VGA now, and some other kind of signal later via firmware. Just thinking out loud.

The connector is not the issue. I can use that type of HDMI connector and drive just about any kind of digital signal down it including ethernet. The issue isn't the physical connector. HDMI is method of sending digital video over connectors using the TMDS signals. The intellectual property issue is the digital video format.
Clearly there are some gray areas with HDMI, whether it be the connector or the signals. The only way to clarify is to talk to the HDMI people.
I meant USB-C + VGA - is this workable?
