Though this PDP-10 was the original 1968 model with discrete transistor Flip Chip modules and wire-wrapping, it had been heavily modified, adding virtual memory and paging support to expand the original 1,152 kB of core memory. The result: students at the MIT Dynamic Modeling Group (part of LCS) having access to a PDP-10 KA10 mainframe - heavy iron at the time. MIT’s Laboratory for Computer Science (LCS) was fortunate to have ties to ARPA, which gave MIT’s LCS and AI labs (formerly part of Project MAC) access to considerable computing resources, mostly in the form of DEC PDP systems. More affordable computer systems were becoming available for purchase by businesses as well as universities. The computer revolution had just taken a fierce hold during the second World War, and showed no sign of subsiding during the 1950s and 1960s.
But more even more than a technological tour de force, Zork is an unmissable milestone in the history of computer gaming. They used every trick in the book to pack as much of the Underground Empire into computers that had only 32 kB of RAM. For portability and size reasons, Zork itself is written in Zork Implementation Language (ZIL), makes heavy use of the brand-new concept of object-oriented programming, and runs on a virtual machine. And though it may be hard to believe, Zork, a text-based adventure game, was the Fortnite of its time. A common use case is APRS, which is often used on VHF bands to send weather and position information out, but there are plenty of other uses for it as well.Ĭontinue reading “Long-Distance Gaming Over Packet Radio” → Posted in Radio Hacks Tagged amater radio, colossal cave adventure, data, gaming, ham, packet, pdp-11, radioĬomputer games have been around about as long as computers have. The unique features of packet radio make it both an interesting and useful niche within the ham radio community, allowing for all kinds of uses where data transmission might otherwise be infeasible or impossible.

Information is then sent back to the Kenwood and attached Mac in much the same way as a standard Internet connection. It broadcasts these packets to his node, which receives these packets and sends them to a PDP-11 running the game. For this build, aka is using a Kenwood TH-D72 which receives the packets from a Mac computer. Typically this involves something like email or SMS messaging, so playing a text-based game over the air is not too much different than its intended use. Packet radio is a method by which digital information can be sent out over the air to nodes, which are programmed to receive these transmissions and act on them. One of the best examples of this we’ve seen recently of esoteric radio use is this method of using packet radio to play a game of Colossal Cave Adventure. While there is a small amount of truth to this on some local repeaters or specific frequencies, the spectrum is big enough to easily ignore those types and explore the hobby without worry (provided you are properly licensed). The amateur radio community often gets stereotyped as a hobby with a minimum age requirement around 70, gatekeeping airwaves from those with less experience or simply ignoring unfamiliar beginners.
