  1. Thanks for the additions/clarifications. My list of "official" disks was on the short side. I wasn't aware of all the Plato courseware disks. I did know about the p-code card software but didn't mention every example. Neither of those packages are very mainstream among the typical TI owner, though they do deserve a mention. It's all just a fraction of the TI catalog, compared to the hundreds of third party offerings. -Ed
  2. TI released companion/support disks for several of their cart programs such as TI-Writer, Editor/Assembler, Multiplan, etc. So no, there's not much of it. Most of their published software (that I know of) was strictly in cartridge form or on cassette. Most disk-based software was third party or user-written.
  3. If you plan to discard the desoldered chips, you can snip the legs off and remove each pin individually. Probably much safer to the board traces as well, since you can observe them as you work. Much easier than trying to get all of the pins on a chip clear and free, then pull it intact. The only advantage of this method is you could possibly reuse that chip if it was still good. Or to be able to test it by substitution in a socket with a known good chip, and perhaps discover if it was actually bad or not. You could do one chip/socket at a time and retest. Starting with the socketed chips. Maybe you get lucky and find the bad chip right away. And if your work creates a new problem, you catch that in time to correct your last couple of steps. If you do all before testing any of it, you may not have a clue where things went awry. -Ed
  4. One use is to connect to BBS over Telnet.
  5. See my edit above. I was typing it wrong, just like they told me too! Once I figured out you just enter the new baud rate fully, i.e., 9600 instead of just 96, it's easy to change. My TI has done 19.2 pretty reliably. I have the ESP set for that now on my Mac. The ESP is supposedly set to 115,200 at the factory. This module was defaulted to only 300, but Ian upgraded it to 2400 when he built it and shipped it to me. BTW, that made my experiments plug 'n' play for the most part, with just a couple obscure gotchas to make it interesting. -Ed
  6. Eureka! I revisited the link I posted just above and solved my 2400 baud limit. All we needed to add were these two commands: at&p0 and at&k1 after which we can type at$sb=96 to set it for 9600, higher is also possible. Next change your term program to match and bingo! I can now test 9600 and see what my TI's limit is above that. Edit: It's even easier. The internal listing has an error. Instead of typing at$sb=96 as it says to do, I "accidentally" typed "9600" and was surprised it worked. Tried that again, typing "at$sb=19200" and was able to connect. at?

  7. You can do a lot more with one of these ESP8266 flavors. The one I have seems to be the ESP12E which breaks out the ESP8266's pins on a larger board for easy access, plus adds quite a bit of support hardware. The software can be up to the individual user and their comfort/experience level. Mine has some features "hidden" or beyond my understanding on how to access the flash memory. All I can find on my board is "modem" software. Reflashing with new or edited software uses simple tools on PC, Intel Mac, Linux or Arduino. What to reflash it with is the question. A good jumping off point to learn more about 'em is here: https://1200baud.wordpress.com/2017/03/04/build-your-own-9600-baud-c64-wifi-modem-for-20/ It seems like the one featured there for Commodore is very similar to mine. It's a whole 'nother world I've never dabbled in, but have been curious. The Internet of Things.... -Ed
  8. It's easy to use Telnet with this little board. For the TI with PEB and standard TI RS232, a 3-wire connection is all that's needed. TI DB25_____ESP DB9 RX 2 _____ 2 RX TX 3 _____ 3 TX Gnd 7 _____ 5 Gnd Yes, I have RX to RX and TX to TX. A quirk of how TI set up the serial connector on the RS232 card. I'm just using solder-pin connectors and a ribbon cable, so it's easy to make or modify. I seem to be locked at 2400 baud since I'm unable to edit the setting in the ESP. I believe Ian <TMA-1> used his Arduino to access it from the USB connector side. From a term program over the RS232, typing "AT$SB=96" it goes through the motions, but doesn't change. I simply lose contact with it till I reboot the ESP and change the term prog back to 2400. Oh well, 2400 is plenty fast to read or send messages, which is all I've done so far. And as noted in my prior post, the wifi itself must be set to WPA or WPA2 security. Myself, I use WEP, so must change the wifi before using the ESP board. All I got onscreen otherwise was "Error." Though I could call up the ESP's default list, I could not connect to Telnet. Hope this saves some grief for someone who uses WEP as I do. Here's a pic of my TI setup. Too bad I accidentally cropped out the ESP board! It's getting power from my Mac over USB. I'm using an unmodified copy of Telco set to 2400 8N1. Not real convenient at the moment. The console is sitting sideways to the old, blurry TV and PEB on the floor in "tower" mode. I'm mostly using it to port my floppy collection over to emulation as I find the time and inclination. Typing messages right now is strictly hunt and peck. If I start using Telnet more, I'll rearrange things or just use the Mac to connect. Blasphemy! Another couple pics show how I connect it to the Mac. I have Keyspan's Mac DB8 serial to USB adapter and an old Mac modem cable. Connect power to the mini-USB port the Keyspan to the Mac also via USB. The keyspan driver is a simple install, with a program to choose which of two ports to use. Set your term program to match the port, and connect at 2400 8N1. And there you have it! Cheap and pretty easy way to get on Telnet! Maybe Ian will add how he's able to edit the ESP's defaults. -Ed
  9. Sorry I derailed this thread. I was feeling little squirrely.
  10. You didn't see it because it never saw wide release. I may have been the only user. I took several small XB utilities and glued them together into one large pot of spaghetti code. I had TI-Base and wanted to use it to maintain a database of my TI disks and wanted to semi-automate the catalog creation. CatLib was in my collection but didn't use it. That program may have been some inspiration for Catman. Or not. So long ago I don't remember. My version of a Disk Librarian lets you add where a disk is stored, gives each disk an auto-incrementing number and includes space for notes and comments on a disk and each file. Multi-session, new additions are appended to a pair of associated files. I also created several TI-Base files to sort and use the data, so you'll see options for that within Catman. Sadly, it didn't play well with MacV9T9 but worked fine on the iron. I haven't tried it much in other emulators. Here's version 2.14, first as TIFILES, then in V9T9 and my last version 2.2 in V9T9 format. Also my disk library created by the program converted to normal text. Enjoy! Or delete, as you see fit. I liked using it and spent a lot of time working on it. I still refer to the master disk listing it helped me create. -Ed catman214 CATMAN21.4 CATMAN22 TI disk libprg 91.txt
  11. I hate those bright LEDs myself. I'll cover them with a bit of masking tape and maybe a dark color Magic Marker over the lens to dim them. You could install a higher resistance resistor to dim it that way. My EXB cart has gotten pretty flaky. The other day I took a small square of a green dish scrubber, sprayed some CRC contact cleaner on it and rubbed down both sides of the contacts and also shot a bit into the cart port as well. That helped as much as anything I've tried. CRC would work on the switch as well. It's cheap and found in many hardware stores. I use that stuff instead of DeOxit. Once I switched to a firehose extender cable, my sideport contact issues disappeared. -Ed
  12. Hmm. I'm rusty on Funnelweb, but somewhere there's an option for choosing which drive to use for certain things. That setting might be global and that's carrying forward to the SL. I configured the menus, but that's about as far as I got with customizing. I never tried the script. -Ed
  13. My Mom had one kinda like this one. As long as you kept the stylus in the correct slot, it worked quite well. -Ed
  14. Here's an FW doc file and another on the Script Loader SL. -Ed FWDOCØE1.28 FWDOCØSC.LL
  15. I changed the first Gosub to Goto, and of course changed the Return on line 100 to Goto 10 and it worked that way too. Take out the Else and have two If/Then/Gosub. Hmmm, that may not work either. 10 A=INT(RND*10)+1 20 IF A>5 THEN A$="GREATER THAN" :: GOSUB 100 :: If A<=5 THEN A$="LESS THAN OR EQUAL TO" :: GOSUB 110 30 PRINT A;"IS ";A$;5 40 GOTO 10 100 PRINT "> TEST" :: RETURN 110 PRINT "<= TEST" :: RETURN Or you could break line 20 into two separate lines with an If/Then/Gosub statement for each result. -Ed
