As a follow up to this, I also have an apparently original Toshiba AC adapter for a Toshiba T1000. It is labeled as: AC 120V 60Hz 15W DC 9V 1.1A...

That thing has a completely different motherboard compared to a standard Model I; it looks like it has a printer port built in, an onboard power...

A quick-and-dirty fix would be to tie the +5 to PG via a simple RC network. Probably good enough.

Pink with "Hello kitty" decals might be nice... :)

The 80286 existed in CLCC, PLCC, PGA and QFP . Initial shipments were made as CLCC--to my knowledge the 386 never used that packaging.

Would it make sense to ask questions about this problem at http://www.nextcomputers.org/forums/ ? Maybe someone there knows how to help...

I ended up finding a severely blown fuse on the main power board so replacing that is certainly a good start when it comes to diagnosing this...

I see. Thanks. This site about the Kingston SX Now! CPU upgrade modules also provides some information relating to this topic. Apparently, the 286...

Tested the power supply and power harness. I made one mistake, I swapped the -15 and -25 on the H720 connector. So I corrected that and the band new...

I found it...the flash is banked by 32k chunks, with a 1:1 mapping from $8000-$FFFF (FLASH $0000 = PET $8000)

Last year I started taking notes during meetings on a Z88 - newly acquired by me having wanted one since my original died in 1990. It typically...

Georgia, US. and yourself? The yellowing doesn't bother me. Thanks!

I just really want to clean it. It Irks me how people take photos of these things without even wiping them down.

Quite simple: the 386sx needs at least 20 more additional pins than the 286, so no way to use the same socket. And that's also the reason why drop-in...

I guess the ability to support an external CPU cache was the main reason for going with a different socket?

We did a little more work on the SOL yesterday. All of the old pads in the keyboard have been removed. We pulled a Wang keyboard from the warehouse...

I had a 1512 when I was a student with a 30MB HD and 5.25" floppy drive. I added a 3.5" floppy drive, and it was a great PC that ran everything that...

Isn't that what most games do anyway? I mean, games don't run in slow-motion on slower systems, they just draw fewer frames per second - keeping the...

I have a 1512 with the same problem- dead Miniscribe HD- this one the 8438 model. The PC boots fine with the system floppy, and works fine otherwise....

Why would you need to know the speed of the system at all? In a racing game the movement of things on the screen would depend on elapsed time and...

All working now. I installed the Lynemouth Software Commodore PET ROM/RAM, set to 40 column, 50Hz, BASIC4. The built-in Wedge opened subdirectories...

I sent reply, but not published yet. Hi Patrick As you mentioned, the problem was with connector pins in PSU. Attached a picture before...

Update, after some further testing and loading a set of specific NeXTDimension tests onto my NeXT Turbo Cube....
