My friend Ryan P and I picked up a few things for our collections over the past weekend from my friend Garrett’s BitHistory.org warehouse. The highlights being a nice Tandy 1000TX, a Commodore Amiga 2000, an IBM 5153 CGA monitor, some accessories (KB/Mice), some misc PC ISA/PCI cards, and finally a pink GTE Starlite phone for my wife’s living room end table.
Finally got my Raspberry Pi 3 all configured to replace my old outdated power-hog Pentium 4 dial-up server. It’s running Raspbian Buster, with mgetty configured to answer the modems. I have a multi-port USB>RS232 adapter that the 4x 56k USR Modems are connected to. The Pi and RS232 adapter are both mounted on the plywood shop wall. My Avaya Definity PBX provides the dial-tone and ringing, there’s a hunt-group (ext 2222) to dial into for all the modems.
Picked up four inexpensive 48-port gigabit layer-3 switches (Nortel/Avaya 5510-48T) to upgrade my network infrastructure, one is acting as the backbone switch in the house,
and the three others (office, workshop, and entertainment center) are linked to it with dual gigabit LACP links. The network has been reconfigured some to save power, turns out these Avaya switches draw about 95 watts at idle. I am down to using two of them, the main backbone one, and one in the workshop. I have pulled a bunch more cat5e, and one OM4 LC fiber cable up to the office and removed that switch entirely, and for the entertainment center I have bought a small 8-port low-power managed switch.
Also I have pretty well completed integration of the new Avaya Definity G3 system. It’s now running all the telephones in my home and workshop. I’m utilizing 2x (out of 4x) Cat6 lines to provide 8 extensions to the house, and a pre-existing two pair cable to extend my Centurylink CO trunk, and “Door Phone” call-box CO trunk to the Definity from the house. I am definitely outgrowing the cabling capacity to the house from the workshop, I need to add at least one more Cat6 cable, though I am toying with the idea of running a 25-pair cat3 telecom cable, then I could reclaim the 2x Cat6 cables I’m using, and upgrade to 4 connection LACP data link to the workshop.
Spent the past weekend “geeking” out with my friend Ryan P and our friend Garrett of Bithistory.org. Ryan P and I drove from Minneapolis MN to eastern WI to meet up and spend the weekend playing with, and sorting through, retro computers and parts with Garrett.
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 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.
- The final CAT5 cable from the house feeds into a 5-port gigabit switch mounted below the PBX, that switch then feeds
- Netgear 16-port gigabit switch on the workbench
- Cisco 24-port 10/100 switch (with gigabit uplink) for the PC display wall
- CCTV security camera
- Netgear 600N wireless AP and 4-port 10/100 switch which feeds
- The Dial-up PC
- a 2nd CCTV security camera
- 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.
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.
Here’s the photos from my trip to the Living Computer Museum.
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.
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.
