  1. Is there a way to see the CRU bases of all devices ? To get the TIPI to work in the end I had to change DipSwitch 3 last pin (to CRU >????), but then it started to work with TIPI luckily. (I can see CRU for TIPI with CALL TIPI), but forgot to check each time changing the jumper (left pins, I moved it up 2x times, but could not get it to work) See video for settings here:
  2. The left button is used (pressed) to fixed the screen-mode in case it is locked-up in the graphical mode. Sometimes just enter something like 1 REM (ENTER) and it also switches back to text mode. Sometimes it is locked up, then remove all power of all devices (remove power from the TI-99/4A, Mechatronic 80 Col. card, remove power from the 32K + TIPI, etc.), wait for a few seconds and start-up again.
  3. Mechatronic 80 Column Card: Loading an 80 Column Text editor program stored at (URI3=) ftp.whtech.com/TIPI called EDIT80 https://www.youtube.com/watch?v=ykjePolTM7k
  4. TIPI and CRU? ---------------- To connect the TIPI to the Mechatronic 80 Column Card, the CRU (Communication Register Unit) address had to be changed (it did not work on the TIPI somehow, but I changed DIP Switch 3 last pin (and no clue which CRU address it is now. Default is >1000, and advised not to change it according the Mechatronic manual. (Is TIPI also is using CRU >1000 ? when the jumper is on the bottom two pins, see the video) I tried to move the jumper between pins on the left side pins, without a working result https://github.com/jedimatt42/tipi/wiki/crubase According this the TIPI CRU base is at address >1100 https://github.com/jedimatt42/tipi/wiki/tipi-installation Does someone know a program to see all the CRU occupations ? (in an easy to understand format ?) With the TIPI connected, I can save programs to the TIPI (DSK2.80XBTEST) Mechatronic 80 Col. Card - demo of 26 rows (= Max.) and 27 rows (note that row 26 gets refreshed when reaching row 27 and if you do more rows you see it blinking) https://www.youtube.com/watch?v=hqIzsAoGQLA

  6. Mechatronic 80 Column Card (9-pin) RGB interface to SCART/RGB plug Pin 1 = Ground to Pin 18 is Composite Input "Ground" / Sync input "Ground" Pin 2 - not used Pin 3 = Red to Pin 15 Pin 4 = Green to Pin 11 Pin 5 = Blue to Pin 7 Pin 6 - not used Pin 7 = +5V ("RGB trigger") to Pin 16 Fast Switching (if you get Black and White / Grey pictures, probably you still use Composite and it is not triggered to use RGB) See: https://www.retrogamingcables.co.uk/trouble-shooting-guide-for-rgb-scart-cables https://en.wikipedia.org/wiki/SCART#Blanking_and_switching Pin 8 = Synchronization TTL (Transitor Transitor Logic) to Pin 20 Composite video input / Sync. input Pin 9 - not used Audio - Need to come from the 6-DIN plug (European consoles) or 5-DIN plug (USA consoles) and need to go to 5-DIN Pin 3 Audio to Pin 2 - Audio input Right 5-DIN Pin 3 Audio to Pin 6 - Audio input Left (Combine Pin 3, as the TI-99/4A is mono audio output) https://justinpaulin.com/2014/04/21/testing-a-texas-instruments-ti-994a-without-power-or-video-cables/ Use Pin 2 = Ground to Pin 4 Audio Ground For Audio on a Europen console (DIN-6) 6-DIN Pin 5 Audio to Pin 2 - Audio input Right 6-DIN Pin 5 Audio to Pin 6 - Audio input Left (Combine Pin 3, as the TI-99/4A is mono audio output) Use Pin 6 = Ground to Pin 4 Audio Ground
  7. Today I got the Mechatronic 80 Column Card to work with a self-made RGB to SCART cable. (note: not all TV's, etc. do support RGB on their SCART interface). This was tested on a Philips 42PFL5604H/12 TV with 2x SCART/RGB interfaces: https://www.philips.ae/c-p/42PFL5604H_12/-/specifications
