Interesting to see the original employee sales receipt for this. $250 in 1982 is about $815 today.
This is for the expansion system chassis and the disk drive.
This is employee pricing, for the plebs it was probably at least 3 times as much? The only price I could find is for just the disk drive alone (~$400 street, or about $1,300 today). [You'd also need the interface card, which costs extra.]

I guess #retrocomputing but current was August, so.
Also have a note about Kent demoing his implementation of his-ansi-cl style error handling introduced to python.

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: https://gunkies.org/wiki/UNIX_Fourth_Edition
We have arranged to deliver it to the Computer History Museum

Utah computer history: This IBM 7030 at the Computer History Museum is from the BYU physics department, used from 1972 to 1982. It features a 64-bit processor, well ahead of its time at its 1961 release, and was IBM's first transistorized computer. Only 9 were made. Before this machine's use at BYU, it was used at MITRE Corporation from 1962.

alright made a new picview release.

Hey so I got a new thing! It’s a Performer PL-CL-SE accelerator for the Mac SE from MacEffects. Supposed to make the lowly SE run like a SE/30 at 16Mhz.
Let’s pop it into one of my SEs and see how it “performs” 😄

I am delighted to announce the release of my latest project:
Fully documented source code for The Sentinel, Geoff Crammond’s 1986 masterpiece.
Here’s the repository; deep dives coming soon.
See thread for details.

Getting a fake AppleTalk ImageWriter to show up in the Chooser took longer than it should have.
The Software Preservation Group at the Computer History Museum compiled a list and bibliography of Interlisp implementations. Did you know that Interlisp also ran on IBM 360/370 mainframes?

So I've attached a USB to serial adapter to my laptop and hooked it up to the user port of my C64. After four lines of BASIC it actually displays a login prompt! How cool is that? Apart from the fact that the encoding is totally broken and the whole thing runs at only 600 baud.
