The 8 sector thing on early DOS came from the datasheet for the µPD765 FDC. It was overly generous with the gaps, probably on the assumption that...

Cheap, yes - but don't do media mail for anything important - it takes FOREVER and often stuff goes missing. And unlike even first class, there's no...

Thank you for putting up the video.

I tried with this disk set a few months ago. Got pretty far in the process, then it started wanting to put stuff on my C:, but I only have two floppy...

There are pics of the actual board at oldskool.org

Also found these really good programs: PictView. Freeware for DOS. Recognizes over 40 file formats. Can resize and convert between formats. ...

The Tandon single sided drives are TM100-1. There should be an IBM label with a part number on each drive. If you can't find the drive model number,...

The one shown at here] ?

hi! So right now I'm just trying to whack DOS 6.22 on it, as I don't have a DOS 3.x image running on anything. That may change soon; I have...

this card is the same as the STB Super Res 400, no? Show photos. I know there are some posted already somewhere.

I will take a look at any pictures you post and if I recognize anything, I will mention it. I am sure others will also take a look so there is a fair...

Appreciate the use of the picture; snagged (and will attribute you as the source). If you can make a higher-res version of the box, both sides, that...

DOS 2.x upgraded to 9 sector tracks from the 8 sector tracks of DOS 1.x. The 5150 controller and drive should work fine with DOS 2 or later disks....

Yes. The difference is the version of DOS, not the drive (other than being double sided vs single sided). 1.0 was single sided, 8 sectors per track,...

Thanks, bud! Mine's been in a box for ~18 years, and I never have tried it. Actively working on resuscitating my PC6300 system, and then plan to...

This is what I am talking about. Notice how on this hardcard that connector is plugged in to a cable that runs to the power on the hard drive.

Generally the lubricants that work better for sliding surfaces are in the Lithium grease family. They are suited to metal surfaces that slide over...

Looks like you are laying your finger directly across the pads of a capacitive keyboard (not pushing a key). I would not bet on that working...

That would be a question for Ray Carlsen. Truly, Robert Bernardo Fresno Commodore User Group - http://www.dickestel.com/fcug.htm Southern...

Just to add to this thread because it is about trimmer capacitors, the color of it indicates its value. These little trimmers were made in Blue, ...

Yes, I moved it a bit, it's available here: ftp://ftp.oldskool.org/pub/drivers/ATT/6300/Hardware%20Expansions/Display%20Enhancement%20Board%20(DEB)/...

I would certainly be in support of that, for obvious reasons. I cannot advise on such a project due to limited understanding of...

Looks like Cherry keyswitches - I'll bet the switches still work as the shafts are complete. Even the one on the top row likely has enough shaft to...

Trixter, Do you still have the DEB software accessible somewhere? I couldn't get to this link. I've got a DEB card, but need at minimum the...

Two hard disk controllers in a system at the same time like that is just asking for trouble. Even if it says it can change the address, or disable...

Nice find. Too much of the these types of vintage stuff is ending up in recycling.
