I've tried to write some bytes at 0xA0000 and 0xB0000 manually and reading them back, which always resulted in 0xFF. that means the memory isnt there, in the sense that ram lines are pulled high when non-existant. I presume the card is doing its own ram refresh... I also assume you meant 0xB8000 …
Re: Identification help needed: I/O card with memory?
Posted on 2020-09-05, 14:53
the chips are 82c450's, which are serial port chips (56k). and two 40 pin ide connectors maybe but I dont see any chips to control them.

Imho it seems like you're taking the difficult route of using libx86emu library, as you'll then need to deal with any incompatibility issues. Instead of relying on the card's bios, the simpler way would be to perform the initialization directly via registers programming and ignore the bios …

Hi! I'm building this slightly weird contraption to learn more about the ISA bus. I have connected an ISA slot to an Arduino Mega (basically just an AVR microprocessor with a lot of 5V capable I/O pins) and I'm directly writing and reading from an attached ISA card. nice. I've seen MDA cards on avr …

(That aside, I do also want it to be suitable for anyone who wants to write New Old Stock floppies and sell physical copies of their modern retro games. That's why I'm trying to keep the size down.) makes sense. I have an option in mine to reserve Xkb on disk one, if you choose to use disk sizes to …

Would you mind either saying that in a permalinkable download page I can link to from my blog post or building a new install bundle containing a license file to that effect? i put in a 'its freeware' in the install.txt and reuploaded it. i dont know how long that link will last, i have not bothered …

well yeah i wrote it in 97, its just a utility, freeware. nobody cared about that stuff back then. i dont care about distribution, like the masses of anything that got uploaded to bbs's back in the day. also, i think your going down the wrong road trying to rewrite everything to your own functions. …

i have a neat dos installer that has some of those requirements http://mega-tokyo.com/si103.zip its an installer rather than setup, as doing tricks like modifying config.sys/autoexec.bat can get tricky when it comes to multimenu stuff... and this was originally written in 97...

my k62+ has never not booted up with its caches enabled and in 450. i use setmul in my autoexec.bat to go to 500. it has no impact on any memory managers I know off. even if i disable l1+l2 an set speed to as low as possible (like 66 or 100) and reboot, it always comes back up with caches on at 450 …

Re: MIDI direct connection (gameport to gameport): is it possible?

only midi input needs an opto isolator so if your just doing output, should be ok. I dont know if soundcard gameports had opto isolators or not.

maybe difference in cpu emulation. maybe dynamic vs normal or something. maybe your app has self modifying code or something.

Powered up the SCSI hard drive (120MB - Maxtor 7120SR) on the GVP HC+8 in my Amiga 2000 -- it works and boots to workbench! I found some more SIMM memory in a box in the basement, installed it, and I now have 8MB of RAM. I also did the motherboard mod to enable 1MB of chip memory. This is going to …
Re: How likely am I to miss the SC-55?
Posted on 2020-07-31, 14:54
the roms size on 55+88 are small. so samples are small. your not missing out on much if anything. I dont think we need to worry about that 1 game that needs capital tone feedback that only a sc55 with a very specific firmware does. the 88 has more polyphony which is nice... for dos games that use …
