    Texas Instruments made much better computers than Commodore.

    The Ti 99/4A is faster, has better sound and much better graphics.

    Forget the C64 and get a TI 99/4A, fast !

    Pablo - don't start a flame WAR. I do have 4 TI-99/4A and I may agree with technical factors but I don't think there is a need to incite flame. Thank
    You.

    I support TMS9900 based systems and 65xx systems. (If you know what I mean -
    I support TI and Commodore comps.)

    I like them both.

    Yeah - I even have a PEB and a PCB board for a USB/SM card for the TI. Just need to pick up some components.

    Yep, too bad that there were only 15 or so programs for it. But these all surpassed any C64 programs. For instance, TI Invaders was MUCH MORE like the original arcade game of 1978 than any Space Invaders clone on the C64.

    Most of the time, when ever there are different selections that can
    be made in the computer world, each selection has features that are
    not shared by the others. This is the case when you can choose
    between either a TI 99/4A or a C64. When they were in the department
    stores, TI BASIC was said to be even more sluggish than C= BASIC.
    I tested their computational precision by evaluating 4*atn(1) (pi)
    on each. IIRC, the TI's result was correct to more decimal digits.

    Back in the 80's a multi-platform magazine, Home Computing I think, published
    a type in Basic program that would create an amortization chart for a loan. They noted that some Basics were more accurate than others. IIRC, the TI99
    was at the top, with the C64 and TRC-80 (or maybe it was Atari) tied for
    second place. At the bottom was the IBM PC.

    I'm not here to argue which is better, history has shown the C64 has
    more fans...
    But the 99/4 came out 5 years before the C64... the 99/4A a good 2-3
    years before, so they really aren't comparable... It'd be like
    comparing an Amiga to a C64... Oh wait, you all do that...

    I had two friends. One had a TI and an Apple II clone (Franklin). The
    other had an Apple II clone (Syscom). I had a TI. Once I got "Tunnels
    of Doom", can you guess which one of our houses we spent most of our

    You should not take words so seriously, I was around when the TI was in the shops.

    But the TI99/4a did have a lot of flaws. Here's a nice page:

    http://perso.club-internet.fr/pytheas/english/TI99_history.html

    I'm Dutch. Maybe some 250 TI99/4a's have reached us overhere, while there
    were thousands and thousands of C64's.

    Look, the C64 made it because it had loads of memory and was easy to proram.

    The TI99/4a had 256 bytes! Ok, it also had 16Kb of video memory, which you could partly use for your own program. But that was SLOW because it had to
    be shared between the VDP and the CPU. And then... The VDP is 8-bits wide,
    so the nice and fast 16-bit processor had to share the video memory AND have
    to access it 8-bits at a time! Come on, what were the TI people thinking?
    'The computer L@@KS nice, so people will buy it anyway'???

    The thing was unprogrammable, you allmost needed a computer-degree to
    program the TI99/4a. You needed to plan your program, which is Ok for
    computer buffs, but not for hobbyists who want to go just that little
    further than BASIC.

    Every half-wit could program the C64. And that's why the C64 made it and the TI99/4a didn't, even while the C64's BASIC was trash.

    The TI99/4a people forgot the KISS principle (or maybe it wasn't documented
    yet and they were the first to encounter it): Keep It Simple, Stupid.

    No need to call each other names over it, the facts are there, it's history.
    I do agree that it is not necessary to rub it in.

    I tested their computational precision by evaluating 4*atn(1) (pi)
    on each. IIRC, the TI's result was correct to more decimal digits.

    That's all very nice for when the computer is used by scientists. But TI
    sold the TI99/4a as a homecomputer. They never should have done that. They
    went head-on with Commodore, while their computer was simply not what a hobbyist needs/wants.

    The TI99/4a was a beatiful machine, and it had an even more beautiful
    expansion rack. But people who would have bought the TI99/4a didn't have the money for the expansion rack.

    Had TI made a much cheaper expansion pack for the TI99/4a, or simply a
    plug-in memory pack upping the memory to 48Kb, then it could well have blown the C64 away.

    Anyway, TI reclaimed much of their losses through the MSX computer. It used
    the same VDP as the TI99/4a :).

    The TI99/4a computer was meant to be an entertainment machine by their marketing. Look at the ads, they allmost all show the TI99/4a running a game
    or educational software, and some business graphs. Scientists and mathematicians still used CP/M machines, Apple II's or were buying the new
    IBM PC (1978) because that came with Microsoft's excellent BASIC (which was
    at least as precise as TI's). The first TI99/4a I ever saw was running TI Invaders in the shop. I remember ads with pictures of the whole family
    sitting around the TI99/4a.

    Just as we don't agree on what the computer was meant to be, the designers
    of the machine and the marketing people had totally different ideas on what
    the computer should have been. It is a sign of how bad TI's marketing people communicated with the design people and vice-versa.

    All games, most educational software and certainly most business software
    just don't need such precision. What they DO need is lots of memory. The
    money spent on making such a good BASIC could have better been spent on
    adding extra memory.

    Now, Runge-Kutta integration does indeed need speed and precision, but the TI99/4a was certainly not the only computer delivering it (I already
    mentioned the Apple II and the IBM PC 5150).

    TI would have done better if they had made two different designs for
    different markets. They could easily have done that. Tandy had already shown the way with their Model 1 and 3 for home users and their other models for business users. Apple already went a little further than that. They invented the Language Card in which you could load a language of choice, with your precision and speed of choice. Of course the Apple II was much too expensive for most home users.

    Now, one last word. I am not flaming, it's YOUR perception of my post. What
    I do know is that you apparently don't have an open enough mind to discuss
    the strengths and weaknesses of each computer. Why can't we discuss the differences, what's the problem with that? If I were really flaming, would I have written so many arguments? So please, open your mind, get out of the
    past. The TI99/4a is dead, the C64 is dead, the VIC20 is dead. Are you
    really so lame as to fight over some corpse?

    Maybe I should add that I am Dutch and don't allways use the right choice of words. It's because English is my second language (Dutch being my first and German my third (ahem, coincidence)), not because I lack intelligence.

    Once again, proving your knowledge...
    The original TI memory expansion WAS a separate module that plugged into the side.

    The computer was designed prior to 1979, when it appeared. The 16k was
    large back in this era of 1-4k computers. The Apple had 16k or 48k at
    the time, and the TI was designed with 32k mapped as expansion RAM.
    The 256 bytes was enough for the GPL Interpreter, which was in a 6k
    GROM.

    No, it was easy. You didn't need to poke/peek addresses to write a
    program. It had nice editing facilities, TRACE, BREAK, line
    number/renumbering

    Every half-wit could program the C64. And that's why the C64 made it and the TI99/4a didn't, even while the C64's BASIC was trash.

    I don't follow this argument. I think it was because the uP was more
    familiar. And hobbyists love familiarity (the 990 is a strange CPU).
    And the home market, the 99/4 was targeted for, wasn't quite ready.

    The heart of TI-99/4A technology is a minimalized version of the TM990 Minicomputer and the TMS9900 was designed well before they decided it for
    use in a microcomputer. They designed the core technology for a
    minicomputer. Hence its VERY radical CPU design compared to typical CPUs for microcomputer. The TM990 had a far more powerful OS than MS-DOS at the time. Remember DX-10 and DNOS ???? Given they put enough RAM in the system and
    all - they could have put the DX-10 or DNOS OS onto the TI-99/X line of computers. Not to mention the TI-99/4A traditional boot environment which
    could have switched between modes. For example - they could have switch
    between the BASIC and the DX-10 or DNOS or the cartridge. Whatever, it is
    just modding the main menu.

    TI's main mistake was going into the ultra-low market with the C= because
    the main cost was mainly this - the TI has more chip components than the VIC-20. MORE Chip components = MORE cost.

    BTW: the 990 was the minicomputer and the TMS9900 was the CPU which replaced the older TM990 CPU boards with a single-chip version of that board in the TM990/10 mini-computer.
    The TI-99/4A used the very same CPU as their minicomputer counterpart. The slowness was not the CPU but the double-interpreting BASIC to GPL to ML
    process instead of BASIC to ML direct which would have been faster than the
    C64 despite the multiplexing to 16KB 8-Bit memory via the VDP. Of course by 1986 - they could have up the VDP into a 16 Bit VDP connected to 16-Bit RAM. They could have even expanded the address bus/registers in the VDP to a
    24-BIT address. This was something TI had the capabilities of doing but TI decided to stick with their strong market "calculators".

    TI's marketing department and problems with video/power have something
    to do with this. Their distribution outside the country was always
    poor.

    The computer was designed prior to 1979, when it appeared. The 16k was
    large back in this era of 1-4k computers. The Apple had 16k or 48k at
    the time, and the TI was designed with 32k mapped as expansion RAM.
    The 256 bytes was enough for the GPL Interpreter, which was in a 6k
    GROM.

    I think their main mistake was the "upgrade" that only allowed TI-licensed cartridges to run.
    That GRU mod (if I remember what it was called correctly) was in the beige models rather
    than the black/silver ones. We developers decided to write for other
    systems because we
    either couldn't afford TI's royalties or were just unwilling to pay to run
    our software on
    arrogant TI's machines.

    Another factor was that, to develop assembly language programs, you could
    use a stock
    C64 with tape drive. To do so on the TI, you had to have memory expansion,
    a disk drive
    and the PEB to hold the cards. Sure there was the Mini-Memory cart but it
    was so limited
    as to be useless for developers.

    Well nowadays, we can get by that. We can make a tape drive that sports its
    own memory and I/O. Actually, - do something similar to C= "intellegent disk drives". Then you can bank the tape drive to it. In fact the ROM to drive
    the drive would have been on the drive itself. In fact - there is ABSOLUTELY
    no reason why tape drives can't be intellegent like the disk drives and be
    on a TI.

    Of course, this was an issue then. Though - this is not the limit of the TI.
    It could do a whole lot more than people generally expect and I know that it could do alot more. In cases, we could have used 65c02 from WDC for the
    Drive Controller main CPU if we wanted to.

    All of these options are something that was known then but I think issues of patent would have made it trouble to use the 65xx. Use a TMS9900 instead.
    Then again our drives would have been 16-Bit drives. Hmmm.....
