How much does each card cost?

BOM is $5 or so, PCB is $1 - am author but HN is limiting how fast i can reply :(

Very nice! At that amount your biggest expense would be in time.

Have you ever considered offering this as a service to others? I'm guessing you could make some pretty big savings in parts too if you were ordering in bulk.

I am going to have a small batch made now, as I mentioned in the article. Then we'll see

Fun story: since the kernel is kept in a FAT partition that Linux can (and does) mount on /boot, and since gcc works, one of these cards is currently sitting on my desk compiling its own kernel, so that i can then "cp vmlinux /boot; reboot" and have it boot a kernel built on it.

Please do post an addendum to the page with the time it takes:)

it is slowly working on it :)

> Of course, C is not the language one uses when one wants to go fast Never expected to hear this one.

Not a child of 8 and 16 bit home computers?

Contrary to modern knowledge, C compilers were quite crappy back in those days, it was the increasing tricks used by C optmizisers, specially regarding the nowadays so beloved UB, that really improved it.

There is a reason why Michael Abrash books are all about Assembly.

"My business card emulates a long-obsolete MIPS-based DEC computer, which then runs Linux" is a more accurate, and certainly significantly more impressive, description :)

Just you wait, i am working on booting ULTRIX on it, and then hopefully emulating JAZZ system and booting windows NT (video provided over virtual vnc over virtual ethernet over usb)

What, no Xerox Alto?

Love your work.
