RIP, sorry to hear this.

#4182859 TI-99/8

Posted by mozartpc27 on Sun Dec 23, 2018 8:49 AM

I am more of a Commodore guy but I have an interest in all old systems and the TI-99/4 is one I am currently trying to get back into (sold off a collection I had for some cash for another project, but now feeling the itch again).  


But as a Commodore guy I keep a close watch on current projects out there in the scene and by far the most exciting is this: the Mega65, a latter-day attempt to create, essentially, the infamous never-produced Commodore 65 prototype machine for production.  Details here: www.mega65.net


It honestly looks like it is coming together, slowly but surely, and amazingly.


It made me think what other unproduced machines might be take np by their corresponding communities.  The TI community is so strong, I naturally thought of the TI-99/8.


Has there been any thought anywhere for folks to work on this?

#4176822 Looking to get back into TI-99/4A

Posted by mozartpc27 on Fri Dec 14, 2018 7:17 AM

About a year and a half ago I had to sell off my TI-99/4A collection to fund another project.  At the time I had a TI-99/4A with an original box, the PEB with disk drive (and a few other cards I never got around to testing/using), and several carts. 


Well, I'd like to get back into it.  If anyone has such things to sell, PM me.


You guys are the friendliest vintage computing community by the way, by far.

#3928400 I never thought I'd ever say this about my TI-99/4A hobby, but...

I am more of a Commodore guy but I had picked up a TI-99/4A at a local convention, built up a bit of a cartridge library, and finally, about a year ago, bought a PEB at a great price from a guy on vcfed. I didnt use it much and I have a toddler at home so my time for the retro computing hobby is severely curtailed these days, and in the end I chose to sell my setup to fund another project (a retro car I acquired).

I am seriously considering hopping back in. I have to say, without a doubt, the TI-99/4A community is one of the very best and most geenrous, open, and friendly retro computing communities out there.

#3898350 Why is the importance of ColecoVision almost never brought up historically?

Posted by mozartpc27 on Sun Nov 26, 2017 8:44 AM

That's exactly how my uncle ended up with a CV system BITD. His daughter had to have the doll that Christmas and purchasing a CV was the only way he could get it at the time. They were literally bundled together - what a racket! So when we'd visit, played the system of course. Funny though... even he ended up purchasing Expansion #1 for it, so we could bring our VCS carts over. Remember playing 2600 Pole Position, Combat, Ms. Pac-Man, Venture, Mousetrap, SuperChallenge Football and Super ChallengeBaseball as much as or more than the CV stuff he had at the time. :lol:

This is how we got our CV too. Mom wanted to get my sister a cabbage patch doll and had to buy me a ColecoVision. Fortunately our birthdays are 8 days apart so we each got our gift, and I think my cousins already had a ColecoVision so I had some familiarity. My mom then went on to buy an ADAM so we doubled down on the Coleco thing, and indeed it is the ADAM that I use today.

#3797336 PEB troubles.

This may be nothing, but you referred to "DSK1." as a command and not as part of your file path. Show your full command, such as:


Is it possible since you set it aside for a while, the syntax has been forgotten?

Note: filenames and device names that make up the file path are case sensitive.

EDIT: the subtle Next button on my phone escaped me, and I thought this thread ended a page back.



:dunce:  :dunce:


I am an idiot!!!!!!!


I completely forgot that the DISK commands only work if you type them in ALL CAPS - which of course is very subtle on the TI-99/4A, because even the "lower case" character set appears to be ALL CAPS.


So this was my problem!  So stupid!  My only question is - since it was the COMMAND that was wrong, rather than it being BASIC being unable to read the damn disk, why did get error codes of the style x0 on any command I tried, instead of a BAD COMMAND NAME type of error?

#3789671 PEB troubles.

So a special thank you to arcadeshopper for agreeing to loan me an Extended Basic cartridge with which to test the system as I hAve it.

In the mean time, any other suggestions about the disk drive issue? Seems like a very strange problem to me.

#3693827 Donkey Kong conversions by Atari

Posted by mozartpc27 on Sat Feb 11, 2017 5:37 PM

One of my interests within the interest I have in old computers & gaming consoles is collecting ports of Donkey Kong and Donkey Kong Junior.  Just something I really enjoy doing.  I try to always pick up any released-at-the-time conversions of Donkey Kong available for any system I own.  I've therefore played two versions for Commodore, the ColecoVision version, the Coleco ADAM tape version, the NES version, the 2600 version, the Ti-99/4A version, and the Atari 800 version.


Of all of these, I think the Atari 800 and TI-99/4A versions stand out as best, and of course were programmed by Atari.  Personally, I think the TI-99/4A version looks the best, but the Atari 800XL version plays a little better.


All of this, however, leads me to my question.  As I'm sure you all know, depending on the version, the opening screen can be oriented to the right or left.  The arcade of course was to the left.  If the conversion you are playing is oriented to the right, it usually has only four levels of girders on the first screen, instead of five.


What I can't understand is: why did Atari program the beautiful looking TI-99/4A version with the arcade "correct" number of 5 girders, oriented to the left, but on the version for their own machine, they used only four girders, oriented to the right?  Mario himself also looks more arcade correct in the TI-99/4A version than in the Atari 800XL version.  It seems odd to me that the one they made for a competitor's computer wound up looking better than the one they made for their own in-house computer.


I can't imagine anyone has the answer to this, except if it has something to do with screen resolution, but it bugs me.

#3692461 This Ti-99/4a pic always makes me laugh

Boy am I glad I found this thread.  Ever since I read about the video controller, and the potential ability to read/write to VCR tapes, I have been intrigued, but everything I had ever read heretofore had suggested that the video controller was never actually produced.


And yet, lo and behold.


Mad Hatter, I see you are still occasionally active on the boards.  Did you ever get your video controller up and running with a VCR?  Why is it only compatible with certain VCRs?  Any VCR I have ever seen has certain standard inputs and outputs and that's it, so I'm curious.  Does your video controller have a serial number?  I wonder how many were, in fact, produced.


I would LOVE to play with that thing (not asking, just a fond wish!).

Never mind... I alighted upon a solution that will work, hopefully.

#3653662 Arcade ports?

Posted by mozartpc27 on Mon Dec 19, 2016 6:18 PM

Sort of off-topic for this thread, I guess, but I saw KAZ's post and was reminded about the forthcoming Donkey Kong Arcade cartridge and it got me to thinking a bit.  Now, I do not have the ColecoVision Super Module... I kinda want one, but that is another topic for another day.  I have never purchased any homebrew; and with respect to arcade versions, in this day and age, I am sort of nonplussed by the notion of "arcade perfect" homebrew ports.  I mean, I remember, as many of you do I am sure, feeling that arcade perfection was the pinnacle of imagination/achievement with respect to home system ports.  It was the unachievable dream.


But today, in an age of MAME, I can play the arcade games themselves, basically perfectly rendered, without worrying about a "port."  Thus, I am less intrigued by the notion of getting "arcade perfect" versions of games for the ColecoVision.  I actually remember feeling a certain amount of disappointment when I saw how close the Mario Bros. port to the ColecoVision wound up being to the arcade version... what I was hoping for was a "ColecoVision" version of Mario Bros., that would be in keeping with the style of the other Mario-based Nintendo CV releases, Donkey Kong and Donkey Kong Junior.


Does this make sense to anyone else or am I just a lone voice in the wilderness here?

Wow, where'd you find it / how'd you get it?


Even if I had one there wouldn't be room in my house, but it is undeniably awesome.  Congrats!

#3600321 Why isn't the 130XE the dominant Atari 8bit?

Posted by mozartpc27 on Fri Sep 23, 2016 3:34 PM

I am very new to the Atari 8-bit line, having "grown up" with Commodores.  I am still trying to get my 1050 disk drive working.


I therefore don't have much of an opinion about the XE vs. the rest of the Atari 8 bit field, but I will say this: the 800XL (and the 1200XL) have the most attractive stylings of any 8-bit computers.  I like the C64C/128 look, but that brown-on-beige is really sharp.

#3571130 Q*bert

Posted by mozartpc27 on Sat Aug 13, 2016 12:24 PM

Had to post this somehwere: just played my best game of Q*Bert ever.  Round 6, screen 2.  145,975 points.  Would have been second place in the most recent high score competition for that game... but still.


The whole thing about doubles in speed at the beginning of the sixth round (I always default to starting on skill level 1, don't even think about it.  Old habit from kidhood).

#3464406 New to me Atari 800

Posted by mozartpc27 on Wed Mar 9, 2016 7:59 PM

Any closeup of that EPROM ?


Don't have a closeup for you right now, but I did locate the sticker which I believe was on the chip that fell off.  it says:


A stylized logo that appears to make the letters cdy (it's the "c" at the beginning I am not 100% on - it's definitely a "d" and a "y")








David Young


And I just realized that... duh... "dy" must stand for "David Young."  Not sure if the thing around the dy is supposed to be a "c" or not.  From another thread on the board, looks like that was a replacement OS:




omnimon was a replacement OS, with ML monitor built in, very useful...


Is this the likely culprit?  How would I go about getting a replacement for this chip... not necessarily another of these custom chips, but whatever chip was originally supposed to be there?
