  1. hahaha! CLAUS you have influence on this!!! i know i read your article and ran with it!!! If i remember correctly...yes!..16k banks and I split the PIA address space and used it for bank select...you can see the 373 select line hanging off the board, it went to other decoding inside the 800 ('138???) i didnt open it yet..... again..just for shits and giggles. I would love to replicate this setup with static ram...may I reach out to you for technical advise sir??
  2. Yup it worked. when i do these things its just for fun. i dont have any diagrams. there was also modifications to the mother board , thats not shown. but i will re build it and post the schematics.
  3. I totally forgot I did this a long time ago...1 meg dynamic ram (dont ask me what scheme) and a IDE interface for my 800... you can just see the decoded address being intercepted from the other 2 slots
  4. Hi All, what access speed should I be looking at?? I've always wanted to build a eprom programmer for the 800...for shits and giggles!
  5. You don't need skill cause you have balls!! and with the help of all these good & smart guys & gals here, You'll have it working in no time flat!! Cheers!!
  6. I turned 50 this year and all of us here are just to young to know!
  7. Going back to hardware....Ever considered 8 bit parallel to serial converter...can do joystick and 4 buttons at the cost machine cycles to reset and clock in....and only 3 PIA lines
  8. Hahaha! I do stuff and I mean to document it but I get so into it.. I forget!!!! Looks great!
