While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973

Apparently no other complete copies are known to exist: gunkies.org/wiki/UNIX_Fourth_Eโ€ฆ

We have arranged to deliver it to the Computer History Museum

An old reel to reel magnetic tape. It has a label, in Jay Lepreau's handwriting, proclaiming it to be "UNIX Original from Bell Labs v4 (see manual for fmt)"

Australians, please raid your Uncle's old PC in his shed, and help me find a copy of this to archive.

Nice, seems that is the chip that had the foof bug.

Looks like it was based upon the date.

A wide ask here so please boost: my grandfather is trying to get rid of an old business computer, and I was wondering whether any vintage computer people might want it. It was purchased for $50k from The Ultimate Corporation in the early 80s. This ran the Pick operating system, and my best guess is the hardware was originally manufactured by GE or Honeywell. It's about the size of a half-rack and currently lives in Brandon, Manitoba, Canada. It has sat covered in plastic in a chemical warehouse for the past 35 years. Where do people usually post stuff like this other than here? Thanks!

Photograph of one of the compute module trays pulled out of the lower part of the computer. It is a large circuit board with a ribbon cable trailing off the back into the computer.

Here's another new artwork: "An Hour with ELIZA," a dot-matrix print of a conversation between the 1960's "psychotherapist algorithm" ELIZA and ChatGPT 4.

A screenshot of a really boring text conversation between ChatGPT 4 and ELIZA. It starts, "Please tell Eliza about your problems. As an AI language model, I don't have personal experiences or emotions..." It's on dot-matrix paper.

I would apologize for posting what at first appears to be another "tech toot"...but since I churned out almost 40 drawings for this talk on the Forth programming language, I don't feel bad about it at all. Here's the slides:

I happen to know some of you enjoy space ships, calculators, and old computers as much as I do.

#MastoArt #RetroComputing #Forth #ConfusedCat

Four slides from my talk, each featuring drawings: Chuck Moore sitting in a chair. Chuck Moore as a wizard turning the integer 4 into 12. An HP-35 calculator. A confused cat using a 1990s era computer with CRT. The mouse looks like a mouse.
Four more slides from my talk with four more drawings: A minicomputer (the size of a fridge) saying "I have 16k of core!" A teletype with punched paper tape reader and writer. Chuck Moore sitting at a Univac 1106. Chuck Moore as conspiracy Charlie from It's Always Sunny in Philadelphia (a screenshot which is often used in memes in which someone is trying to explain something complicated).
Four more slides from my talk, each with a drawing: Forth in Space with Chuck Moore on an EVA from a rocket saying, "May the Forth be with you" (my daughter's idea and I am so proud). The Rosetta spacecraft approaching a comet. The Jupiter Ace home computer. The Canon Cat home computer.

Super neat way to get hardware protected mode on a Z80!

There's something else this thing came with though I am particularly fond of - a Banksia 28.8Kbps modem.

Banksia is, near as I can tell, an Australian company that produced modems - and nothing else I ever saw.

This was the brand of modem I had as a kid, dialling BBSs. I had this exact type of 28.8Kbps modem even into the internet dial-up era, never getting a 56k modem at all - i went straight to cable internet from 28.8.

So I'm delighted at getting one of these again! #retrocomputing

And now, the final part of The Haul - the machine that all these games came with.

It's an LC 575. It doesn't power on, unfortunately, or so I'm told. I plan to open it up and do an inspection for blown caps and the like at some point soon, probably when my better-than-me-at-electronics friend is free to give it a look.

I'm hoping I can get this thing working again - I used a Mac Plus during my school days, along with Apple ][ early on.

But this era of Mac is foreign to me.
