  1. Yes i know i could make something but ultimately i'd like the original part :0)
  2. I'm after one of the small blocks used to mount the Serial port on the rear of the Mega STE / TT (see pic) If anyone can help let me know thanks
  3. Can i use HN27C4096CC-10 or does the rom need to be a -12 or -15 ? Thanks
  4. Thanks So do i need to do anything to this image or can i simply burn that file onto a rom?
  5. Can anyone point me in the right direction of a working Falcon TOS 4.04 rom image please so i can burn my own TOS rom Thanks
  6. OK so i used a phone camera to check the LEDs on an STM1 i have that doesn't move left/right And sure enough i can see all 4 LEDS emitting a purple coloured light So does this mean the LEDS are ok? and there is something else causing the lack of left/right movement? On this particular mouse i have changed the cable and caps and still the issue, no broken solders or tracks What else to look at apart from changing the chip and testing resistors?!
  7. Thanks for this Is it also possible to save the data on a working Gal/Pal into the rom burner and then burn back the data to a new chip?
  8. These chips - U62, U63, U67, U68 Chips C30283(0/1/2/3)-001 PAl/GAL/IC And the longer U44 chip
  9. Does anyone know where i could find the gal / pal images for the 5 small chips on the Falcon?
  10. How do you use a cell phone to test the wheel emitter?
  11. I have a logic probe. Ok so i will check as you say around A3 area... Thanks for your help
  12. I'm just going on what is stated in the Falcon service manual for testing CPU, "check data and address lines to see if they are toggling" it says when test cartridge fitted on initial power up The manual doesn't specify which data and address lines to check so do i assume any of them??!!
  13. OK so there isn't 1 x data line or address line but many data and address lines!
  14. I have the PDF of the Falcon CPU with pinout of the pins but none are marked as Data or Address How do i find out these 2 lines? Thanks 68030 QFP.pdf
  15. Can a logic probe be used for checking CPU clocks and Halt lines? I'm ultimately new to this so want something simple to understand and use
