TI-99/4a MiSTer Core

Just to be clear, that was not the issue and was actually why this is so confusing. Getting the proper boot.rom is what allowed me to get a directory (catalog) of files in Disk Manager and load/save BASIC programs in TI BASIC in the first place. That made it seem like I had what was needed to support loading everything from disk so I figured I could load the EA ROM and then load EA 3/5 programs... apparently not. Apparently I needed an EA ROM with disk controller support in it. I'm still trying to learn about the TI's funky architecture and hopefully one day I'll pull my TI and PEB out and experiment with them (and hopefully they'll still work 🙂).

 

Thanks against to those that guided me through resolving this issue. I doubt I'd have figured it out solo any time soon.

Just to be CLEAR, I think you mean EA GROM as it is not a ROM as those are Assembly based and EA GROM is GPL based.

If you want the source code for it I can post it.

You know probably a good idea would be to read the ti FAQ since that has good explanations of all the pieces of the puzzle

That's one of the reasons I said the mister designer obviously never used a real TI

He should make it so it clearly loads the hardware as options and pulls the ROMs in as selected instead of making us load them into all of the cartridge zip files separately for us to have disk access.

There's one "mister designer" - Alexey Melnikov, aka Sorgelig. He's the guy responsible for the software framework and design of the many add on boards. MiSTer covers all the platforms from the beginning to PSX-era, so as you might imagine there's quite a few of them. There's no way one person can snap their fingers and instantly fix every problem and grant every wish in regard to all these cores, many of which are developed by other people and/or were ported from other platforms.

MiSTer is a WIP, and every update brings a slew of new fixes and tweaks.

Ok what is EA ROM? As this is why I said EA GROM is not a ROM?

Is there some new version of EA GROM written in ROM for EA?

Does GPL now run from ROM now?

I did not see any such demand or claim. The criticism was concise and precise, including an observation that has since been confirmed, followed by factual information which could be taken under advisement.  None of it appeared disparaging.  Engineers and technically precise people often say exactly what they have to say without bracketing it with personal fluff.  No need to take or assume offense.

Only Singe Density Disks? I have a Corcomp Controller not a single disk is Single Density they have all been converted to DSDD.

Been using TIPI so even Corcomp has been pretty much useless.

At least I can access TIPI from XB or RXB.

Hope they can updated MiSTer to DSDD and access from XB or RXB.

New post on the MiSTer TI99 thread that could be interesting from Flandango (the guy that is supporting this core):

 

"I managed to get the TIPI firmware modified to work with Mister and the TI core and also connect the Raspberry Pi via the User Port.
If there is any interest, especially if you have some soldering skills and willing to make your own cable, I can post the core here for folks to try out.
"

 

So, if there is some guy here that have both and is wanting to try, just ask on the TI99 thread (TIPI and MiSTer TI99 core). ;-)

I have this working here, much nicer than copying single disks over..

Greg, could you pls. prepare a tutorial/video on how it's working on MiSTer?

 

In the meanwhile, the TI99 core was also updated with P-System support. 🙂

I'll put that on my list

I haven't seen a working grom file for pgram yet

I didn't see the point of buying the MiSTer 'analog board' given most cores were migrating away from the second sd-card and I (personal preference) connect all my RGB things to a single HDMI display... So my MiSTer setup has bespoke LED and button setup, and some USB hub, basically... I think the user-port boils down to some DE-10 pins with 10k pullups and some inline resisters ? 100ohm ? as well... Has anyone seen documentation anywhere on just the user port without the 'usb-ish' connector?  I wouldn't think those resisters necessary for PI to FPGA connections.

So basically it's pretty simple you have to buy a small USB breakout board which he includes in the instructions I ordered one and they sent me the wrong board so I had to order a second one. I use Dupont connectors to connect that board to the pi. Make the SD card as instructed in the TIPI wiki https://github.com/jedimatt42/tipi/wiki and boot the pi with that installed.

After that it's just select the TIPI on mister and CALL TIPI in ti basic.
