404 Monday not found

I have IBM DOS 2.1 for the PC-XT & IBM DOS 3.3 on disks the XT likes, but they don't have a setup program. The disks were installed before being shrink-wrapped.

The only other utilities I have are DEBUG & FDISK. None of the Debug commands worked, & FDisk simply says no HDD.

The Diagnostics disk from the XT's Guide to Operations recognizes that a controller is present & jumpered for a single HDD, but it doesn't say what the controller is or what kind it is.

But the only Mountain Computer manuals I can find are for their Apple II products. None for their IBM PC controller cards.

And I know it's a hard drive controller of some sort, because Mountain Computer sold it for the PC & XT (5150 & 5160) at the same time they sold hard drive kits for Apple IIs.

It's similar to to this tape controller sandwich:

but not.

Anyone who knows rare add-ons for #vintagecomputers, can you point me to the manual for this? It's a Mountain Computer part number 05-04031-02 that came in a HDD-less IBM 5160 (PC-XT) I rescued. I can't tell if it's an MFM, RLL, or ESDI controller or what the jumpers do.

BOOT ERROR PB

Meaning: Remove peanut butter & jelly sandwich or other foreign object from disk drive.

The computer arrived with this drive's door shut. How did they even get that far in there?

When you ship #vintagecomputers, folks, *PLEASE* cover and protect the openings before pouring packing peanuts into the box!

I now own a TRS-80 Model III that *must* be disassembled because styrofoam peanuts are clogging the disk drive cavities and edge connector openings.

I shouldn't be shopping for vintage computers, especially at this hour, but someone is definitely as much of a geek as I am. They're selling a TI-99/4A for $99.4A:

Good morning, and merry Ostara.
