Well, thanks Wagner's TechTalk. I got the SD card all setup but the FG is not being recognized. The Reset switch works just fine but I think I need to program the atmega. This looks like I get to go do some studying.

Thanks for that link I have read a good deal of it. Here's the solder point we were concerned with.I think you should check this again. The solder is almost touching another lane.

We have a TI professional here who has some good advice on soldering:

Nope nmBoss is a cool guy .. did this for me.
And I think he put the CPU 180 deg wrong

Well not gonna say no. May try it out tonight if I have time. Have to give wife backrub ... I use this as a trading mark.. "Let me do *thing* and I'll give you a backrub."Well...
If you dont mind running an emulator .. In another emulator... (Because derpier things have been done..)
You can go for Eltech's windows emulator. (which is WINE + their proprietary x86 emulation core.) You could theoretically put classic99 inside that.
I happen to have a copy installed on my phone (the windows emulator that is.) I could give it a shot and see how well it works?
Seems to work well.

Thanks I was worried about that one too when I reexamined the pic. I think it is some flux but will look

My header was too big for the printed case. Going to cut a section out of the top to make it more accessible.

Looks to be fun!!Not for the 32k, but for the FinalGrom99, yes.

Feeling rusty behind the iron again. Well it's a start.

Thank you very kindly. Putting them in now!Yes, these are 0.1uF, exactly what you should have in those 4 spots next to each chip's top right corner. Ceramic disc caps go in either way (unlike marked types which a definite + and -.)

I probably should have checked to see if there was another "Help the noob build his stuff" topic on the forum but..
So I have almost all my parts together for the aforementioned addons. I have been practicing my surface mount soldering and a guy (also named Matt HAH!) Is going to be overseeing the process. The through hole is not my worry at the moment.
Quick Question: These ceramic 104's should be sufficient for the few called for on the 32k sidecar yes?
My hope is others that have not spoken or have yet to speak can use this resource in the future.

2 years ago I built my pc with a small 32g optane m.2. Boots so fast... mmm. That's what got me on the Solid State kick. Been looking for more and more solid state since.I would take my SSD equipped MyCloud NAS and a hacked wifi router with me, personally.
I can bring a lot of loot with me for very little space. The MyCloud is about the size of a fat book, and with a sata ssd inside it, you can bang it up what good in transit and be fine. I have mine hacked 7 ways to sunday, so it does all kinds of fun things (Including running a plex server).
I could bring several whole game libraries for several systems, not just the TI, with me that way. Pack a bluetooth gamepad, and maybe an HDMI cable.

I really need to get my FG built. Lol

Assuming you have already written an interface protocol for PCI ? Or am I missing something in translation?

Ok, so look at a grouping of batch files and have it run through FG99 on startup? Then write drivers for say.. an nvidia 680... and have a batch file to incorporate the various functions from the Gpu?Greg mentions the latest and greatest DOS for the TI. When in a FinalGROM it can it can effectively take over the TI reset process bypasses the startup screen and selection menu. So whenever you quit a program (reset the computer), you are instantly back in DOS. If you set up some batch files, you can even build a custom menu system.

Has there been discussion about using SPI IC ? In theory we could load all basic functions on a relatively inexpensive SPI.I suggested this in 2001 at Chicago Fair.
The idea that Gary Bowser and I discussed was swapping ROM 0 in lower and upper 4K pages of multiple upper pages similar to the SAMS memory.

Thank you kindly. Getting that now.What about JS99'er? It runs fine on a phone.
With a more mobile "skin", it's even better: http://lb3.one/js99er/

So I am not normally included in development. Most of my work is based on testing. It may be that my thought on this is uninformed and uneducated. For which I would look for any kind of creative criticism, suggestion, or possibly good humored argument.
I seems to me that there is no way to bring a total connection between the TI -99 and current world, without some kind of radical change. I love Solid State devices. they are cleaner, quieter, more dependable. If there was a way to bring about a newer OS for the TI that would allow for the induction of modern drivers, it would solve a lot of problems. However there are RAM, ROM, and GROM considerations to take into account.
Is there a way to bring the TI-99 forward and keep the retro. Is there a way to make an OS that will function just like the TI-99 and allow for drivers? Is there a way to produce a processor capable of more? I know it would involve flashing ROMS. I think that there are enough Homebrewers that would enjoy a system that could do a bit more with itself. Making games that would keep the retro feel but be bigger in size ... like "Bards Tale (1985)" where the landscape is created at the time of player creation is procedurally generated, and bigger than just Skara Brae.
Atari is coming out with the VCS system. It will have dual boot ability. Onboard OS is Based on linux it is allowing for retro games to be played and allow for it to be used as a Media center for the home streaming. I have to admit that I am truly impressed with the technology. Check out the system specs here :Atari VCS Pretty robust features for the coming age.
TL:DR
Can we make an OS based on TI-99/4a? Can we do what Atari VCS did?
Thoughts and Comments please. and thank you for your time reading.

On 12/1/2019 at 9:57 AM, wierd_w said:In the late 90s, before the rise of USB, many PCI chipset motherboards had integrated serial and LPT IO on the back.
In this case, keeping that thing around is useful if you want to set up/load up some old vintage x86 machines, since you can use a copy of fastlynx to parallel transfer files over. (It's basically like midnight commander, except it can transfer over an LPT cable, or a serial null-modem. LPT was faster.)
Given how the prices on those things has exploded on Ebay, if you have any such old clunkers and you dont love them, load them up with FreeDos and some abandonware, and sell them for around 200$ a pop.
I have a few such boards. The nice thing about this board is that I believe I can put a SATA SSD in the PCI port and have much faster response times for loading Win98 or XP. My choice is to make the one pictured a sort of NAS for Home. I have a few (closer to a Dozen) hard drives that have been wiped. probably use it for some Dos Games I still have lying about. Somehow I want to play Dune again. I think it was x286 or x386 era. More to Follow.

Thanks kindly. It is too bad. I have dosbox on phone but think that an emulator would work better on tablet ... size, it seems, matters. I will see what I can do to create another more singular TI emulator on android. An emulator to run an emulator seems ... cumbersome.

So I dl'd the apk tonight and the characters are scrambled. It isn't on the app store anymore. I did a cursory look but couldn't find out what happened. Needed to sleep for work. Is the author still on the forums? Is it freeware or abandonware? TIA!

Did anyone build their own FG99? From what I am reading it looks like I am gonna need to get one of these.

In order to program the Atmega.
Are their other programmers I should be getting?
Kinda bummed, in that I was looking forward to playing some games this weekend. Lol
I have several Raspberry pi's and could utilize them for the programming. I am no stranger to GPIO's.
