  1. 1. Using FORTH GPL Disassembler as that was always my best one.
    2. Fix the resulting code as it comes out backwards on many commands.
    3. Compile and test the code.
    4. Fix errors and fix so it works in Classic99 instead of some strange set up on hardware.
    I've posted it on eBay

    I know, I found it hard to believe TI would consider it, but I read it somewhere within a series of letters penned to another TI guy, these are available on the net somewhere but I can't remember the path I took to find it. Maybe ftp site documentations deep within I think. I'm sure TI did have a policy of using it's own chips, so that's what made it hard to believe.

     

    EDIT:

     

    They may have been attempting the Z-80 for future CP/M compatability, as they knew at the time the Z80 was used quite widely for business, it can clock over 6MHz in some cases.

    I do remember talk of the Z80 chip being used or contemplated at one time when I was there - but I was in Defense group so didn't know where I heard about it. John Phillips was working on the machine software, he might have been where I heard of it but I don't see him around at this time.

  3. So this adds to my 15 minutes of fame. In case you are interested,  I played bass guitar for The Nervebreakers,  a Dallas "punk" group that opened for the Clash, the Ramones , the Police,  the Boomtown Rats, and the Sex Pistols as well as serving as backing band for Roky Erickson of 13 Floor Elevators fame.

  4. Just fyi, I've been corresponding with the museum that has the better prototype at their location that I donated.  They did add a credit to me for donation as I requested and I enquired if they were willing to turn it on to capture the boot screen but they said they don't do that with the artifacts as they don't want to risk them being damaged. So I hope whomever buys the one on ebay will get good information from roms at least and hopefully gets video working again.

    Who own this early version of the 99/4 computer?

    I would be happy to see its innards, and especially under the top cover hole (optional Infrared feature) :-)

    Hope it has the TMS9900 CPU modification instead of TMS9985 too!

    The other one I had is on eBay currently rchildress is username 

  6. 8I'm about ready to dig them out but wife is having party tomorrow so it will probably be Thursday.  I donated the better Dimension  4 to the computer museum when it was in Boston, trying to win their prize but lost to an altair 8088.

    This one also fired up back then but had a glitchy display if I remember correctly.  Prefer to sell it local to dfw area so I dont have to pack and ship. I'll work on pictures. 

    Also unloading my upgraded atari 400, happy drive, and Atari st 3d glasses stereotek and software but that would be for another board

  7. I need to sell off my Atari systems I’ve got a 800 , upgraded 400, couple of drives, pretty sure one is happy. Just lugging then around from storage to storage for years but shipping is a pain. In DFW area if there is any local interest
