On April 3, 1973 the first wireless phone call was made and Moore’s Law has
now led to the smart-phone being ubiquitous to our lives: Computer
technology and cell phone technology marching hand-in-hand.
Happy computing and talking about it!

My son goes to NC State for CompSci, he might go if he can.

Does anyone here know if the Beaglebone Black Industrial is he same as the
regular Beaglebone Black? I have a couple of the MFM Emulator boards to
build
and will need a couple Beaglebones for them.

Does anyone have a surplus DEC M8340 board with PCB etch level E and
revision F (as imprinted on the handle)?
If yes, please reply to thunter6600(a)gmail.com.
Thanks and best regards

Does anyone have a list of replacement capacitors to use for NCD X terminals, specifically the 17c and 19? A couple searches online don't turn up anything.
I just got my NCD 17c up and running—I showed a pic or two on discord://classiccmp/#terminals a couple days ago—and now while I hear the HV power up the low voltage power seems kaput and the system never comes on. And my NCD 19 won't power up either.
I can certainly take them apart and make lists, and I will if need be, but I was hoping maybe someone had already done so so I could get an order in ASAP. The power supply for these things is in the display portion, which makes me a bit nervous just generally… :)

Some models (e.g., the 150) supported Multibus. In the early 1980s at Tandem Austin we used one with a SUN graphics board in a Multibus slot to prototype a 68000 workstation we were building (but that never became a product). Al Kossow has lots of information about Wicat in bitsavers. Here’s a brochure for the 150: http://www.bitsavers.org/pdf/wicat/brochures/System_150_Brochure.pdf
Is anyone familiar with WICAT Systems?
I came across their ad in BYTE Nov 1981 (page 84), with a claim of
"first family of microcomputers with mainframe capability"
It is a 68000 based system (like the Lisa?), one configuration offers
400x300 monochrome graphics. Ad also claims 1.5MB main memory and a
multi-user operating system ("UNIX/V7 and a CP/M Emulation also available")
called MCS.
Address mentions Orem, Utah.
Haven't come across a price sheet, but I imagine they were quite expensive
($6000+ would be my guess).
From the images, looks to me the main problem is a lack of an expansion bus
(and overall not a very appealing-looking system).
Was just curious if anyone had witnessed one ever running.

This is what I have found after searching, which implies around or before Nov  2017,
