My Vintage Computer Virtual Museum and blog page.

Picked up a Teletype model 43 for the museum. —

I found this Teletype for sale in an antique store in Duluth, Minnesota.

Seems to function in local mode, I need to get the cabling figured out and try to get it working in online mode.

UPDATE: 9/2018: I was able to get this talking to a PC with the right combination of cables and null modem adapter, it was sending/receiving at 300baud.  However I need to source a ribbon for this, the old one is dried up, and fell apart when I tried to open it up to re-ink it.

I’ve tidied up some of the telecom/network cabling. —

I spent some time last weekend cleaning up the cabling mess for our telephones and dialup server, now it’s not such a disaster.  I ran all the telephone/modem connections to a 66 block rather than just hanging it all off the front of the phone switch.

  • 12 of the analog phone lines off the PBX switch run into my house (via 3 of the 4 CAT5 cables in my conduit) for my various vintage telephones throughout the house.
  • 4 lines are dedicated to the dialup modem server (via a call group).
  • 4 more to my workbench for telephone/modem testing.
  • 4 more to my PC display wall for the various PCs and terminals to dial into my modem server.

Network wise

  • The final CAT5 cable from the house feeds into a 5-port gigabit switch mounted below the PBX, that switch then feeds
    1. Netgear 16-port gigabit switch on the workbench
    2. Cisco 24-port 10/100 switch (with gigabit uplink) for the PC display wall
    3. CCTV security camera
    4. Netgear 600N wireless AP and 4-port 10/100 switch which feeds
      1. The Dial-up PC
      2. a 2nd CCTV security camera
      3. Linksys PAP2 SIP Analog Telephone Adapter that feeds dial-tone from my Asterisk PBX in the house to the AT&T Merlin Legend PBX here.

Recently won an auction for a 1969 Carterfone modem —

This is now the single oldest piece of computer gear that I own, you can check out the page dedicated to it, which will be updated as I get it working, and learn more about it, but for now here’s a preview of the photos.

My trip to the Living Computer Museum in Seattle, WA —

Here’s the photos from my trip to the Living Computer Museum.

Current Museum display —

Current machines on display in my museum, this is not my complete collection, there are some machines that are in various states of disrepair, or I just do not have room to currently display.  Not all these displays are currently hooked up, there is no power on the laptop/iMac wall, so they must be moved to the workbench to be hooked up and used.

Added 2 more feet to museum shelving. —

I had a bit more room for shelving in my workshop/museum and decided to make the most of every inch I could and added an additional 2 feet to my display shelving.

Modem mania —

I spent most of last weekend fighting with my Linux box trying to get dial in access working, after days of fighting I finally figure out the onboard serial port wasn’t working, works fine with a FTDI USB adapter, anyways YAY it works!!!

I now have 3 external USR 56k modems running on here for 3 simultaneous logins, with a 4th modem waiting on a power supply which will soon go into service.

Conduit and Cat5 cable from house to workshop. —

My vintage computer workshop is in a detached building, so I have run conduit and cat5 cabling from my house.  I ran 4x Cat5e cables to start but also left a pulling line in place if I ever need to pull more through the conduit.  The cables terminate at patch panels on both ends.

Started moving my collection to its new home. —

I finished my workshop/museum space, here are some of the first systems to go on display.
