  1. Looks like the "8 bit guy" used your book to make a video for his channel: https://www.youtube.com/watch?v=1UzTf0Qo37A At least someone in the comments listed your book as a citation 🙂
  2. I remember releasing software for the BeOS many moons ago, an adventure game called Hopkins: FBI.
  3. The store/inventory. You said you were part of a group preserving it
  4. Got a link to the sofa?
  5. Moved and can not figure out which power adapter matches the Gamer Tek. Will anyone tell me the specs of the power adapter?
  6. I made 75K a year in 1997 as a software engineer in the south. Now I make 75K a year as a software engineer , but houses and cars are far more expensive. People are not as smart now for putting up with stagnant wages.
  7. Thanks for that information. Do you know what did the average house and car cost in 1961, compared to now?
  8. One reason I keep using a Mac is Virtual ][
  9. Just started so it may be a simple answer, but something in that book has me confused. In the book the example puts the vertical blank first , then the vertical sync. This seems backwards to me. From the example on 8bitworkshop.com , the example called 5. Painting on the CRT: NextFrame ; Enable VBLANK (disable output) lda #2 sta VBLANK ; At the beginning of the frame we set the VSYNC bit... lda #2 sta VSYNC ; And hold it on for 3 scanlines... sta WSYNC sta WSYNC sta WSYNC ; Now we turn VSYNC off. lda #0 sta VSYNC ; Now we need 37 lines of VBLANK... ldx #37 LVBlank sta WSYNC ; accessing WSYNC stops the CPU until next scanline dex ; decrement X bne LVBlank ; loop until X == 0 ; Re-enable output (disable VBLANK) lda #0 sta VBLANK ; 192 scanlines are visible ; We'll draw some rainbows ldx #192 lda BGColor ; load the background color out of RAM ScanLoop adc #1 ; add 1 to the current background color in A sta COLUBK ; set the background color sta WSYNC ; WSYNC doesn't care what value is stored dex bne ScanLoop ; Enable VBLANK again lda #2 sta VBLANK ; 30 lines of overscan to complete the frame ldx #30 LVOver sta WSYNC dex bne LVOver Would not this have been correct with VSYNC first?

  10. The growth of Mortgage debt, car loan debt as well as credit card debt have outpaced inflation, while salaries have been stagnant. Perhaps the high debt load and low interest rates explain why your friends have more stuff!
  11. The top few lines just started appearing scrambled in the last few days. Should I buy a cap kit or is this something else possibly?
