Bidded on a Commodore 64 on eBay and I won. The C64 has the reset button mod on It, which is like icing on a cake: top quality and faster than the power switch. I'm planning on buying the 1541 drive, Fast Loader cartridge, and video cable. Also plan on getting a mouse, joystick, and some games on …

So even on the 80286, a limit of 0xFFFF with a BX(0x8000)+SI(0x8000) won't cause a general protection fault? It will if you try to read a word from offset 0xFFFF. not in realmode, no exception will be thrown. also with debug.exe in dosbox, if you read a word like MOV AX,[BX+SI] where BX=8000, SI= …

hidden? its all in his github. https://github.com/skiselev/micro_8088 the note at the bottom is interesting; AS6C1008 (U6) does not have TTL compatible inputs causing instability with 640 KiB memory configruation Workaround use CMOS transceiver U11, e.g. 74AHCT245

Youd have to look at the data sheet. A lot of early ramdacs that were just clones of the original INMos dac are all 6bit (18bit), later ramdac evolved to be full 8 bit (24bit). I have whole bunches of ramdac chips for a project I was trying to do. When truecolour/hicolour was all the rage, ramdacs …

In DOS I use for basic text editing QEdit (TSE Jr) or programming I use TSE Pro (Qedit big brother). for graphic word processing in dos.. you can use Word Perfect 6.2 in graphic mode. obviously if you go windows you have a plethora of word processing stuff.

It just means if you had an 'sb pro' compatible card, you'd try option 1, if your compatability was shit and option 1 didnt work, youd drop to 'sb pro ii', then if that didnt work youd try 'sb pro iii'. there were varying degree's of compatability from the clone makers.

I only ever use smarydrive with disabling write back. i use for read cache only. mostly, ncache2 is much better than smartdrive too! If you have enough ram, a 16mb cache is fine for hd's. ncache2 lets you see the stats, which is interesting data.

BTW, I love this. Did you ever make a C64 or Atari 800 "flippy" disk by notching out a write-protect hole in the other side, doubling its capacity for free? I did, loads, I even had (have!) a special punch tool for it. it worked on c64 because disk drives had 1 head (one sided). in the case where …
