What is a perq and why is it good?

>More practically, there are still a number of Whitechapel MG1's about.

Speaking of novas, I finished Soul of a New Machine. Great book!
>> a linn rekursiv (wouldn't you? ;> )

Is the machine as weird as the name?

>QX10's (IMHO one of the nicest CP/M machines ever built), etc.
Was CP/M made for any specific machine originally, kind of like
DOS was made for a PC (leaving Seattle Computers aside for a moment)
>MDS800, then good luck in finding one.

I believe the system/34 was a Mini. I think that's what those UPS
tractor-trailers are for :)

Isn't microcode hard-wired anyway?
>Philips P800 series machines are not at all common, alas...

What does PDP mean, exactly? Is it something like the PC standard?

Which is?

Which is?

I can just imagine "Sabrina's jungle dungeon - hosted on a Torch XXX"

>96K RAM, etc, etc, etc. It was going to be sold as a home computer...
So, how much RAM total?
