Ward Christensen dies

There was initially some issue verifying this, but there appears to be direct confirmation now that Ward Christensen passed away October 11 at the age of 78, co-founder of the pioneering Computerized Bulletin Board System in February 1978 with Randy Suess — now believed to be the first BBS — and developer of the XMODEM transfer protocol. Although his notional job was at IBM, where he worked for 54 years, he became better known for his prolific public domain software output which was widely used in the early 1980s and his innovations with computer-based telecommunication. He was reportedly found dead at his Illinois home after a welfare check on October 13. Ars Technica has a nice summation. Rest in peace.

Refurb weekend: the Symbolics MacIvory Lisp machine I have hated

Every collector has that machine, the machine they sunk so much time and, often, money into that they would have defenestrated it years ago except for all the aforementioned time and money. Yours truly is no exception.

That machine is my first Lisp Machine and my only one actually using real Lisp Machine hardware, this Symbolics MacIvory III in a Macintosh IIci host. To date it's cost me over $6000 total, primarily its initial purchase price, but also to rehabilitate it and just keep it alive. That's nearly as much as what I paid out of pocket for my $7300 (in 2018) POWER9 Raptor Talos II Linux workstation and my $10,000+ IBM POWER6 server, which I acquired in 2010 and in 2024 dollars would be over $14,000 — and both of those machines have been substantially less troublesome.

For those of you unfamiliar with the general world of Lisp machines, they are, as their name implies, workstations entirely designed around the Lisp programming language. That doesn't just mean using conventional processors with a Lisp runtime either: these devices are built to run Lisp from the silicon up with specific hardware support. (Some of these systems could also run Prolog, my personal favourite AI-adjacent language. We'll play with a surprising small Prolog implementation in a future article.) They existed in highly technical environments as workhorses of the first wave of AI hysteria (you crazy kids today with your LLMs) for applications like natural language processing and expert systems. The genre more-or-less flourished from the end of the 1970s to the early 1990s and included some of the first systems to implement advances like bitmapped displays, networking and pointer devices. In turn, those unusual capabilities caused them to also develop distinctive user interfaces for their unique feature set, years before today's GUI and keyboard conventions we almost unconsciously take for granted were even conceived of. Working with a Lisp machine can be a remarkably different user experience from modern computing and the occasionally jarring nature of those differences isn't something present-day emulators fully capture.

Unfortunately, their rarity also makes them the whitest of white elephants sometimes. Besides what I had to do to get it working properly to start with, the hard drive started timing out and it randomly froze during boot or shortly afterwards. (There was also the matter of me never finishing its setup, let alone getting it networked.) I'm not letting this benighted thing die on me after all I've put into it — it's time for a Refurb Weekend.

So thieves broke into your storage unit - again

If you've been wondering why entries have been a little slow lately, let me tell you a story.

All collectors tend to be a bit obsessive by nature, and us classic computer nerds probably pick up more hardware than we can (or should) store in our residence — especially if the loves of our lives aren't as enthusiastic about the hobby than we are — and thus have storage units for the overflow. I have two small "cold" climate control units, kept small so that I can be out of one or both relatively quickly, as well as a larger "hot" conventional unit at ambient temperature. The hot unit is indoors and not exposed directly to the sun, so it's not particularly hot for sunny southern California, but I keep working spare electronics, hard disks, tapes, etc. in the cold units as a precaution and use the hot unit for non-working parts units, books, magazines and other household items.

Of course, climate control units cost more, sometimes substantially, and thieves use this as a signal that more valuable stuff is likely to be kept there:

Both times I've been burglarized, they were the cold units. August was the second time. So, with crime being a nationwide topic, let's talk about what happens when your storage unit gets broken into and how to recover from it.
