I did the mod for 640KB on the motherboard about 25 years ago. So I have 256k chips in banks 0 and 1. I have enough 256k chips that I pulled from another board to fill the other two banks. I realize that the added memory will only give me about 64k of Contiguous base memory, but I believe there is a good

  2. Fast String Reverse in Assembler

    I became interested in string reversal, a common interview question I remember getting, while investigating methods of converting integers to strings. In the discussion thread I started [1] I used disassembled code from MSC 5.1's itoa() routine. I always feel guilty using someone else's code verbatim in projects written from scratch, even if it was assembly code. Below is the inner loop (14 bytes) assuming a load address of 0x100 using DEBUG.

    Code:
    0100 DEC DI
    0101 LODSB
    0102

  4. 26 PERFECT AMIGA GAMES to play with the MAVERICK 1 | It's a Pixel THING - Ep. 124

    Iíve been messing around with my QuickShot Maverick 1 and ended up discovering a new and far more enjoyable way of exploring certain games that I used to play with a traditional joystick back in my Amiga years.
    So, hereís a list, with no specific order, of 26 Amiga titles that Iíve found to be more enjoyable when played with an arcadish style of controller like the Maverick 1!

  5. Random Cubic Polynomial in Assembler

    I finally reached back into some of my first assembler [1] to write a routine called cubicnom() that generates a random cubic polynomial as the title implies. This pulls together several recent bits of code to seed the random number generator using a string and sprintf the results to a location in memory.

    First, here's a random() function which accepts range parameters BX to CX. Thus if I pass in 1 and 9, respectively, then I'll get back ...
