Can you guess the subject of this weekend's video?

TOPS-10 v7.05 ON-Line!

We are happy to announce public access to our latest PDP-10 offering, an SC Group SC40 "MARS" running TOPS-10 v7.05. This is likely the only TOPS-10 system speaking TCP/IP in the world today.

I'm getting rid of some really old computer stuff. Here's one of the newer pieces.

An old Compudyne CMPD 3SXL/25 that looks like this one:

The case is cracked, but it runs and boots to windows 3.1 right now.

It has an 86Mb HDD.

The track ball doesn't work, but it's probably fixable.

There are two battery packs for it, although I'm sure both are dead.

I'll probably wipe it and put FreeDOS on it before handing it off.

If I don't get any takers, it's going to e-waste.

The Interim Computer Festival is this Saturday and Sunday at 3100 Airport Way S in Seattle from 10am-6pm. Come see the many PDP-8 systems and other vintage computers. https://sdf.org/icf #vintagecomputing #retrocomputing #community

How many PDP-8 systems will be at Interim Computer Festival? So far we believe 5 to celebrate 60 years of the coolest minicomputer you never heard of.

M-Net’s Altos 68000 getting cleaned up for the Interim Computer Festival this weekend. Access the current incarnation of M-Net/Arbornet at SDF Vintage Systems https://sdf.org #vintagecomputing #retrocomputing #community

Home computers that used cartridges were all the rage in the '80s. I'm surprised there was no third party company that sold a replacement lid for the #AppleII that had a hole cut over slot 7, and made self-booting cartridges the user would plug in through the hole.

<insert mockup photo of Apple II with cartridge poking out of the lid>

Working on my Micro 8088 and got the floppy controller done! But I forgot the 3.5" floppy uses a different power connector size (feels like a 1993 rookie mistake.) So waiting on an adapter. In the mean team, switched to my VGA board for some fun.

M-NET the oldest running Public Access UNIX has arrived! The original Altos ACS68000 will be on display next weekend at the Interim Computer Festival. M-NET is now under SDF.org Vintage Systems care. Thanks jfk, cross and tod! #vintagecomputing #retrocomputing #community #bbs

I still cannot understand why the #S100 bus based computers were not a great success in the early 1980s.

It was used for the first hobbyist #Altair computers as well as #Z80 CPU based systems.

The extensibility through standardized components was one of the key features. There were backplanes, cases and exchangeable 3rd party components available.

But people preferred proprietary stuff like #Apple II and #Commodore pet and later #VC20 and #C64.

Is there a cyrillic version of Gorton, @mwichary? Seen in Technical Museum Brno (CZ): https://www.tmbrno.cz/en/permanent-displays/ #vintagecomputing #tmbrno

I dug up my old #Apple #Newton #MessagePad 130, put in a fresh set of 4 AA batteries, and fired it up for the first time in ages. After setting the date and time, I went back to the start and asked it to show me today’s agenda. I guess its calendar can only handle a limited date range, because it sent me back to March 7, 1991. #VintageComputing
