    Hi All,

     

    While waiting for me here in Manila my TI99/4A and PEB seems to be on the blink. When I run anything that appears to want 32K access - the screen goes solid green and all the lights on the PEB go out. So for example, if I have a disk in DSK1, use EA5 to run DSK1.DIAGNOSTIC it starts loading - screen goes solid green and all the lights go out. Power cycling the TI brings it back - then, for example - I might try WDS1.DM2K.DM2K and same thing - loads from hard disk, but then green screen. I can run BOOT (in both 40 and 80) - and catalog disks, however - WDS1 will lock the system up.

     

    Guessing 32K card but looking for ideas. I have pulled out the cards that seemed suspicious - so no more pGram+ or Horizon RAM card - just MYARC DDCC1, SCSI, 32K and Firehose.

     

    Ideas?!?

     

    Cheers, Arthur...

    I bought this from what's left of Radio Shack - and it works great. There is also an excellent Shift838 article that discussed how to wire a power plug into a Speech Synth. I keep my NanoPEB off the side of my Speech Unit - makes it easier to add and remove from the console. Here is the link to the Radio Shack power supply. I don't have a direct link for Shift838 but I believe it's about six months back - an enjoyable hunt nevertheless... :)

    Hey All,

     

    Wondering if anyone has contact with Jaime? I recently disassembled a Speech Synth to add a power socket for my NanoPEB. It occurred to me that the latest NanoPEB has a ton of empty board space - and the only reason it needs to be as big as it is would be the CF card. Using an SD card in place of the CF card one could easily create a new board layout that could fit right into the Speech Synth's "upper deck" so to speak.

     

    Also - anyone try to stuff a NanoPEB into a PEB via. a Rave99? Would that work??? (don't ask why, just roll with it...) LOL

     

    Cheers, Arthur...

    I think that if you find a way to transplant a Core i7 daughter card and a SSD disk drive on the 99/4A, you'll get better performances ;-)

     

    More seriously, I'm not agree. If I still use a TI-99/4A , it's to remember the happy old days with this computer, to revive the sensations it procured me and the pleasure that I had when I discovered its graphics and sound, its programmation and its peripherals that amazed me at the begining of the 80's. For these reasons, I only use 80's technologies with my TI-99 computers.

    If I want hyper speed performances, high colors and resolutions, gigantic mass storages I use my Core I5 and Core I7 Mac & PC computers.

     

    By using modern technlogies onto the TI-99/4A, its soul fades.

     

    I disagree - there is no charm in old floppys going stale - and losing bits of your personal history (literally). Even with Lotharek SD cards emulating floppy disks and the F18A - this old TI has far more personality than my Core i7 monsters will ever have. I actually care about my TI systems and have an emotional connection that goes back to my early teen years. PC's come and go - but I've had my TI in production (running TI-Base) for over 30 years. Adding some new capabilities will just enhance my desire to do more with the TI. That said, my most extreme admiration goes to you and your engineering skills. If you ever decide to put some of your designs into production you have a sold customer waiting right here to send you money! :)

    The Apple Pie is an interesting card in the Apple world that interfaces between an Apple ][ and a Raspberry PI. The pie then emulates disks, serial, network, video - the works... it's basically a slave to the Apple ][ (and capable of being it's own machine as well). A PEB or sidecar that could interface with a PI would then benefit from all the hardware advances in the embedded Linux space. One such card in a PEB could replace every other card.

    I do have a CorComp FDC actually - but have been using my TI 80 track controller here because I feel it's more reliable. I have been experimenting with fbForth from HDX and it appears to run well. Right now however I have been focused on getting TI-Base to run properly from HDX. I am going to write up a post on that as it's a pretty interesting story.

    Been setting this up on my system - awesome! :) Any chance you could read the clock from Fred's HDX?

     

    100 OPEN #1:"HDX1.TIME",INTERNAL,FIXED
    110 INPUT #1:SEC$,MIN$,HOUR$,DAY$,MONTH$,YEAR$,DAYOFWEEK$
    120 CLOSE #1
    Near as I can tell, all current HW clocks are out of production with the exception of HDX...
    Not complaining! :) Love the new menu - much better than Boot - which I used for years!!!
    Cheers, Arthur...

    In that case - what might the clock options be for the TI? I'd like to use the REMIND software, and it would be nice if BOOT displayed the time. I have scanned the binary files for evidence of device input - but still pretty new at this. Seems that if it's possible to hack 80 col support into BOOT that clock support should be easy enough. Right now the only source of time I have is HDX1.CLOCK, any pointers, suggestions or ideas?!?

    Hi Lee,

     

    Seems to work - but could be cleaned up a bit. I loaded the DIR utility - since I have very little experience with Forth (but do have the cart and plan to learn)... :)

     

    Here is what a screen of directories on HDX1. looks like...

     

    IMG 0031

    And here is what a sub-directory with some files in it looks like...

    Very cool!

    Hi All,

     

    Finally have HDX on my RS-232, wondering what apps are fairly well enough behaved to run from it?!? I already have BA-Writer 80, a partial TI-Base install, and a few other things. Any chance of running FW? Is there a hacked 80 col version of Multplan that might run from HDX1?

     

    Just fishing for suggestions and best practices!

     

    Cheers, Arthur...

    This is what a bought... they (2) arrived in a padded envelope. Fairly well padded but NOT in a anti-static pack. You can see the difference in the second picture where I put the old v. new side by side.

    For those who've been wondering what I've been up to lately, I've been working on something interesting for Richard Bell. I received a couple of test boards for the project today, so I had to start building one right away--even though I am still missing a few of the important parts. At least it is beginning to look like a piece of TI hardware. . .and just because I know there will be people asking this: there is absolutely NO timeline on when this will be finished or made available yet. I know there are some bugs on this iteration of the board before I even build one--and I may find more as I try to test it. More importantly, I still have to get a good dump of the PAL for the original Myarc board so that I can make new ones--as otherwise, that particular portion of the project will become a really fun bit of whack-a-mole. . .

     

    Is there a schematic of this card? Or a picture of the reverse side I could look at?

    Got it! :) Super happy!!! Thanks Kevan and Kasrul for your help with this... I have actually wanted an RXB cart for years... I was never able to figure out how to get it working with my PGRAM+

    Two tasks remain - what do I sacrifice for a cart shell (football, personal report generator, something else) and printing a label!

     

    :grin:

    Excellent - read the details in the PDF and the 1284 programmed just as in the procedure. I am still at a loss as to what to program into the 40 though. I have two files...

     

    128K attachicon.gifRXB2015Flash.bin

    4K attachicon.gifRXB2015EEprom.bin

    I loaded code and data memories - as per instructions but it seems like I am missing something.

    For kicks, I programmed the 40 with the EEprom file - plugged it into the board but get nothing other than TI Basic.

    Is there a ROM file I should have that I am missing? I don't see any 512K ROM anywhere?!? (or in the lists)

     

    Very much appreciate the help! :) I've only ever programmed the 40 for Cortex 80 col basic... I am also using the carrier you recommended. I went through that drama with the Cortex project and Kevan was good enough to clue me in to the whole crappy adapter deal... LOL

     

    Cheers, Arthur...

     

     

     

    No, the final versions of the files (I put them into the Cartridge ROM Images thread a while back) should work perfectly. Note that with the 1284, there are TWO files you have to load You have to load the Data section of the chip with the 128K flash file and the EEPROM file into the config area. You then need to load the 512K ROM file into the 49F040. One note on the 040 chips, they really don't like cheap programming sockets for some reason, so I use one of these--and it works every time. Here is Gazoo's procedure for loading the files using a MiniPro.

    Trying to make a RXB2015 cart!

     

    Used the minipro and programmed both chips - both went OK. Plugged them into the cart - plugged the cart into the TI and it comes up with nothing, just TI Basic. Either I didn't do something properly or ???

     

    Programmed the flash into the 1284P - that seemed to complete OK.

    Programmed the eeprom into the 49F040 - also seemed to go OK.

     

    Plugged chips into board, and board into TI...

     

    Is there something else I was supposed to do - wave around a dead chicken or something?!? :)

    For the record - I did manage to make a Coretex basic cart using the same board and a 49F040 so while I am certainly no expert - I did accidentally make it work before... LOL

     

    Cheers, Arthur...

    I have new daughterboards in stock.. a few anyway..

     

    And I'm working on my backlog :P finally got everything set up at the warehouse workbench and now it's just time

    Can I order you a pizza or something?!? :) Sadly - I finally broke down and bought a bench magnifier - eyesight at 50 is starting to drop off... :(
