Yathzee in TML (the missing link) for TI-99/4a

Yathzee in TML (the missing link) for TI-99/4a

Here is another conversion from my Atari BASIC programs to the TI-99. It's a Yahtzee game. I never liked any of the Yahtzee for the Atari 8-bit so I wrote my own. This is mostly a direct port of that game except for the graphics. On the Atari I used DLI to change the font sizes on the fly which can't be done on the TI-99. But, I used Harry Wilhelm's amazing TML program for some other graphics. TML gives the XB programmer access to the bitmap graphics of the TI video chip. You can create Cartesia

Some of my TI 99 from TI-99 IUG

Some of my TI 99 from TI-99 IUG

Way back in the 80s, when I was a kid, there was this thing called the TI International Users Group. The group had a TI magazine and a cassette program exchange. You could create programs and summit them to the IUG who would make them public for others to buy on cassette. If you submitted a program you would be able to get the cassette programs free. So being the cheap-ass I am I submitted a lot of programs to the IUG. Here are some that I recently downloaded from WHTECH site. I know I have a

OeeyGUI & fusion BBS

NOTE: an update of OeeyGUI is forthcoming. I'll post v2 when I receive it from Shift838. the BBS software still works, though, if you just want that.   Here is the OeeyGUI & Fusion BBS that Shift838 demonstrated at the TI99 fest in Austin. The fusion BBS wasn't on the CDs I handed out.   Oeeygui-bbs.zip

creating a USB2SIO cable and installing Respeqt

creating a USB2SIO cable and installing Respeqt

Creating a SIO2PC cable for the Atari 8-bits with RespeQt is one of the cheapest and easiest ways to get virtual drives for the Atari and also one of the best. He's a little how to on creating the cable and getting RespeQt up and running. Not to long ago I built an S-Drive for the Atari (see this blog). Also a fairly cheap and good virtual drive solution. It's portable and easy to use. But it does have one drawback, for me anyway. I do a lot of my development on my PC using Altirra and cros

XB-70 - what if

XB-70 - what if

This doesn't have anything to do with retro computers but with retro airplanes. The XB-70 was a hyper-sonic proposed in the 60s. It had a projected cruising speed of MACH 3, which is impressive even by today's standards. I remember as a kid I of having a model of this X plane. It was 60s cool if there ever was one. I got the below document from I'm not sure where. It's a 'what if' and some of the plans they had for the plane. Here's the NASA fact sheet on the plane. https://www.nasa.gov/centers/

How I installed a UAV board in my NTSC 600XL

How I installed a UAV board in my NTSC 600XL

On the NTSC Atari 600XL the only video output is RF and the picture quality is really not very good, at all, not in the least, bad. So I thought maybe, if I want to use this 600XL for anything more than a prop, I might want to replace the video with something better. After looking around I chose the UAV by https://thebrewingacademy.com/ due to it’s simplistically and it’s cheap at only $30. Plus it has one of the best pictures I have ever seen for a composite output.   Installation:

Adding 64k to my 600XL

Adding 64k to my 600XL

As anyone who has an Atari 600XL knows it only came with 16k. Good enough to run game cartridges but nothing else. Atari's solution was this little device that attached to the BUS adapter on the back. the Atari 1064. These are rather impossible to get a hold of these days (in fact I had a hard time just finding a picture) so the current procedure to up the memory is adding the memory internally. There are several ways of doing this, lotharek.pl/ has a nifty little chip that just

TI-99 40 column text game using T40XB

TI-99 40 column text game using T40XB

I have been going through my Atari 8-bit games and looking to translate them into TI-99 games, mostly BASIC. The games I wrote in Atari MSBASIC are fairly straight forward translations. Atari BASIC has the issue of strings being completely different but can be got around. One thing that both Atari BASICs have in common is the Atari uses 40 column text. This can be a tedious issue to fix when translating to TI99 32 column text. You have to go through each line check, recheck, reformat recheck a

TI99 Resources, sister website with lots of TI-99 resources

https://ti99resources.wordpress.com/ is a resource for TI-99 line of computers that I created a little while back. There is over 8gb of software and documentation for the TI-99 computers.   It took me several months to get it to this point and I'm always adding more to the website.

Mod to MEDIT for APX Pascal to make it work

Mod to MEDIT for APX Pascal to make it work

I have been testing the waters of Atari APX Pascal recent and have been having an issue with MEDIT blowing up when run from the Pascal menu. I twittered the great Bill Lange who gave me the fix. (1) As you probably know, you have to copy the MEDIT executable over to your work disk image in disk drive D2. In addition, MEDIT needs a minor modification for it to work with the Atari Pascal Language System. (2) With DOS loaded, put the work disk into D1. Use the DOS menu option N to create a M

Mille Bornes for Atari Microsoft BASIC

Mille Bornes for Atari Microsoft BASIC

Mille Bornes for Atari Microsoft BASIC 9/5/20 In my quest to put Mille Bornes everywhere here is an Atari Microsoft BASIC version. This game has a rather odd history; it started out as an Atari BASIC game that I got a long time ago from, I have no idea? The 1st translation I made was to the TI-99/4a in TI Extended BASIC several years back. That was a rather difficult translation and almost took a full rewrite. Recently I translated to the CoCo2 BASIC from the TI-99/4a. That was a rathe

the TV Game

the TV Game

the TV game 9/4/20 This is another one that is only loosely connected to the TI99. A couple weeks ago I had a backup drive crash with a lot of my retro-computer stuff on it. Fortunately I have found most of the stuff elsewhere but while looking through my old Atari software I found one of the oddest role playing games ever, 'the TV game'. Way back in the 80s me and some friends of mine came up with a role playing game where you took on the mantle of a network TV primetime pro

Uno for the Atari 8-bit in Atari Microsoft BASIC

Uno for the Atari 8-bit in Atari Microsoft BASIC

Uno for the Atari 8-bit in Atari Microsoft BASIC  I wrote for the Atari 8-bit in Atari Microsoft BASIC. But I did later translate the program to the TI-99 (see Games/Mygame section). Not a lot of people knew Microsoft wrote a BASIC for the Atari 8-bit line. Fact is Atari Microsoft BASIC was going to be 'the' BASIC for the Atait 8-bit line. The only thing that stopped from being the de-facto BASIC for the Atari was that Atari had a requirement that the BASIC had to fit in a 8k cartridge

Super Hiway Chicken Plus

Super Hiway Chicken Plus

here is another game I re-created that I had submitted to the TI99IUG many years ago - super hiway chicken plus. I wasn't able to find the game specifically in the old IUG on WHTECH but that's not surprising. the IUG usually changed the name and removed the original author from the listing. plus, there does seem to be some files missing from the IUG composite. It's a Chicken or Freeway variant that was a much improved modification of another IUG chicken game and yes the name is a bit over the to

Atari 2600 Megamania label

the activision labels for the Atari 2600 really deteriorate over time. So for those games I usually make a new label. Here is a Megamania label I created. It's a cleaned up scanned label so it would keep the original look.

Some software from CD1 ATX

Some software from CD1 ATX

UPDATE: found the bug in the 99/2. erase the ti99_232.ini in the INI directory fixes the issue with it starting in partial emulation mode.   Here is some of the software from the CD1 of the 2 CDs I gave out at the TI99 fest in Austin. I removed the documentation so the file would go over the max file size. also Oeegui will be posted in another post. for those who weren't able to attend the Austin TI99 fest I handed out a 2 CD pack to as many as I had. It contained a disk of lots a

MESS/MAME Geneve 9640 files update

MESS/MAME Geneve 9640 files update

Little time ago I posted some files here that were roll-ups of files for MAME/MESS from the, what I call, the 'other' 99s; that is the TI99-8, TI99-2, TI-99 PSystem, MyArcII XB and the Geneve 9640. Looking over them I realized I hadn't vetted these very closely, especially the Geneve. (FYI: if you don't know anything about the Geneve, here is the Wiki article with some excellent links for a deeper dive on the subject: https://en.wikipedia.org/wiki/Geneve_9640 ) So I went back and pulle

Geneve 9640 part deux, 'Say what???'

In the last post I threw around some terms that might not be familiar to those who may have never used the Geneve 9640. So, here is a brief description.    MYGPL - Programs from the TI99/4(a) can't be run directly on the 9640. A lot of TI99 software has a underlying layer known as GPL in the code. MYGPL has a GPL emulator built in that enables those TI99 programs with GPL to run on the 9640. To run TI99 software with MYGPL you type in 'MYGPL nameofTI99program' at the MDOS prompt.

UPDATE: TI99 MilleBorne, Yahtzee, Uno FASTER VERSIONS

UPDATE: TI99 MilleBorne, Yahtzee, Uno FASTER VERSIONS

I have updated three of my programs for the TI99: MilleBorne, Yahtzee and Uno. for MilleBornes I cleaned up the code for the AI opponent & made it faster.  for Yahtzee I remade it without TML to speed the program up by factor of 2. Drawing the fancy color fonts in TML slows down the program because TML has to essentially draw each font on the screen in high rez. Redoing the program for just using DISPLAY AT speeds things up a lot.  for Uno I also remade the program without the

UPDATE! TI-99 Extended BASIC Mille Borne V3.40

UPDATE! TI-99 Extended BASIC Mille Borne V3.40

After a long time of procrastination I have finally got around to updating the Mille Borne for the TI-99 in Extended BASIC. I have added some sound effects, some voice CALL SAY("UHOH"), sped up parts of the program and cleaned up some minor bugs that had been long standing. This is 'probably' the last version but I have learned never to say never. The game is XB autoboot and is in .DSK v9t9 format. Enjoy. MILLEBORNE-V340.dsk

Uno game in Kull XBII for TI-99

Uno game in Kull XBII for TI-99

I wrote a version of Uno for the Atari in Atari Microsoft BASIC and posted a few blogs ago. Well, here is Uno in the Kull XBII. Kull XBII is a little known package to TI-99 Extended BASIC. Check an earlier post for more on the KXBII package. One nice thing about KXBII is that it enables multi-color text which I use a lot in the program and it looks really good. Multi-color text is the best feature in KXBII. As I detailed in the earlier post about KXBII is there are a few limitations such as
