Apple II

Hello all,

I have a couple Timemaster HO cards with the original Data Sentry branded NiCad batteries sodlered on. One of the PCBs appears to have fared pretty well, with just a little corrosion on the solder pads. The other though appears to have some trace damage perhaps from the battery leaking.

I have a ROM3 IIGS and I wanted a wDrive to complement my BOOTI card for track/sector ordered disk images, which the BOOTI card doesn't support. The thing that intrigued me about the wDrive vs Floppy Emu is that the wDrive has a menu system you can use via the computer's monitor & keyboard, versus having to look at the tiny OLED display. Not a fan of the tiny OLED on my Pi1541 for my C64.

Hi!  A while ago, I ported some cc65 code from CBM to Apple2.  While I was porting the code, I forgot to clean up the control characters, and the results were random attribute changes, i.e. inverse characters and a switch back to 40-column mode.  This leads me to believe that, like the CBM models, the Apple2 also had control characters.  Where online can I find a list of Apple2 control characters?

Hi!  I'm trying to understand hash tables.  From what I understand, every time I process a string of data, look for the first four bytes in a hash table.  If a match is found, scan starting there for a better match.  If only the first two or three match, scan to there, as I do better on smaller offsets.  If the match is at least four bytes, add it to the hash table.  I thought of a derivative: keep an 8k array of bits, where each bit determines if an associated word was used.  If a word in the input was not already encountered, skip the LZ77 scan.
