This is frankly amazing. Among other things, I never thought it was possible to do a parallax scrolling on a 8 Mhz PC using VGA hardware scroll. ...

Question. There are 4 banks of memory. Where is the physical location on the motherboard for the memory between 640kb and 1024kb? I am checking...

No substantive input to offer you, Dave - just cheers from the sideline. Your FP looks great to me! smp

See if FASM meets your license requirements. The assembler itself is a 32-bit executable, so as mentioned above it needs a 386 (and CWSDPMI), but it...

well, Chuck got you sorted out, and is helping you out.. I'll stop blundering, trying to help then... You are in good hands, he has the knowledge...

More updating today (see last post for the link). I have uploaded today's images (although they accidentally have yesterday's date on them)... ...

yep its A RIFA inline capacitor. it filters the 115v/220v line, not required to run the computer but suggested to always replace it look for...

Found 12 more cable plugs/connectors, these are added to the lot.

The reason for changing R5 is to protect the 33v Zener diode at CR7. R5 shouldn't have any effect on the spot, but CR7 can cause the spot if it's...

When Mike's VSG was used outside a housing and battery operated it provided a very convenient and safe way to separate the ribbon cable and the drive...

YESSSSSSSSSS I have been anxiously awaiting! :D that rocks dude!

Or, I am a slower typist than you, but had less to type. More patch wire examples at here].

I know that NASM was able to run in DOS, but it may have required a 386 to run itself. This is definitely true for FASM. Both can create 16-bit...

Those wires likely were put there during manufacture or testing of the boards. I have an IBM 5155 which uses the same motherboard as the 5160. I am...

Text, data, bss segments, with the ability to switch segments at will, and that's it, really. 8086 code compatibility. Nothing exotic. Input is a...

At here] is an earlier thread on the subject.

At here] is pictured one that failed (open circuit) on me some years ago.

It delivers on its promise of being a cute little demo. Very nice work. Harkens back to the days where early demos were nothing but palette cycling...

Casey good for you. I have a 486DX2-66 up and running with W95. However, with 3 other projects going at the same time I haven't had time to 'get in...

I included the rotozoom code in this demo, source and release binaries can be downloaded at github.

What features would you need in this assembler? My compiler is GPL and can handle a source file that was nothing but assembly, but it doesn't do...

Sierra also released a better known word processor: Homeword. See...

See post 35. Falter knows this already. Please review the thread and note the exact nature of the problem.

It looks like a good candidate, but unfortunately I can't use it --- I've got some GPL stuff and the Open Watcom license is incompatible; I can't...

you should not be using a 1.2MB floppy unless you demagnetized it first (you know with those hand-held magnets R/S used to sell), If the floppy was...
