  1. I'm looking for the source code for the PEARLE.PRG ray tracing program by Allen King. The MSA can be found many places including on Atarimania but so far I've found no source code: http://www.atarimania.com/demo-atari-st-pearle_27106.html To my recent enjoyment I found that it runs on my Falcon030 when in Compatability-> ST Low Res Video mode. The Falcon renders each image in about 1hour and 15 minutes which (if memory serves) is much faster than on my original 1040ST. I'd like to see if the program could be improved on the Falcon and TT by using the FPU instruction set and/or more modern algorithms. Bonus Question: Are there other Ray Tracing programs for the ST/Falcon/TT that you might recommend? Especially if the source code is also available. I am familiar with the one that TOM HUDSON wrote for START magazine (referenced below). FYI - For context I am including the first few lines of info found in PEARLE.DOK the text/documentation file that is found with the .PRG ============== FYI - Another ST Ray Tracing program START VOL. 1 NO. 4 / SPRING 1987 The START Ray-Trace Construction Set Awesome do-it-yourself graphics!

  5. Hi - I’d like to sell the whole lot to one buyer maybe $3 per cart. Local to NC or SC would be great but I’m fine shipping in the U.S. lower 48. Please PM me if any reasonable offers. All carts were tested (on a 7800) and working as of a year ago. Thanks!!
  6. eddhell purchased a dozen+ Atari 8bit carts from me. Smooth transaction. He is a good communicator. Thanks!
  7. coleconut purchased an Atari Mega box from me. Great transaction and buyer.
  8. SOLD Hi - box only for sale. Please make an offer + shipping cost. Box is in fair condition, see pictures. Has some handwriting on top. Can collapse it and ship flat (sandwiched with other cardboard) or box it inside another box.
  9. I have had several sell transactions with craigmaloney. He is quick to make up his mind and pays promptly. I agree with the prior post.
