Considering selling my two Tezros

Greetings.

I have a small collection of vintage UNIX workstations that initially started with a purchase of NeXT Cube around 1993 (I have been active for many years on nextcomputers.org under the same handle). My collection includes two quad 700 MHz Tezro machines that I purchased around 2011. I believe that they were used with Flame by a local visual effects outfit before they were retired. I knew nothing about IRIX at the time, but with some help from Nekochan and online documentation I succeeded in reinstalling IRIX on both machines and exploring them for nearly a year. Then my son was born and both machines were stored in my house.

Fast forward to today. I am in the process of trying to rationalize my collection as it is taking up significant amount of storage space. I very much want to keep the Tezros, but it is extremely unlikely that I will have any reasonable amount of time to devote to them. While recently looking through online forums for possible solutions to temperamental booting (drained SNAPHATs), I also realized that working Tezros are hard to find. After a long internal struggle, I think I am potentially prepared to have someone convince me that I need to let them go to a good place, where they will have more time devoted to them.

I have replaced SNAPHATs in both machines and they are no longer temperamental when booting. One does seem to have a somewhat tired Dallas chip since L1 does not come up on the first plug-in, but always comes up after I unplug and replug the power. Both machines have run without any issues over the last few days. One is equipped with 8GB of RAM and the second one with 6GB. They both have dual display V12 options and DM3 cards. One is in very good cosmetic condition with few small scuffs on the plastic. The second one has more scuffs on the plastic. No plastic panels are broken or cracked, but there is some darkening of plastic panels due to oxidation over the years. The machines are extremely clean with no dust, no rust, no dents, etc. I will supply additional information, hinv output, serials, photos, etc. over the next few days if there is interest.

I am located in Ontario, Canada. Would much prefer not to ship due to size, weight and fragility, but I understand that finding someone interested locally is unlikely.

Thank you.

Sadly Minnesota is not local. You may want to post photos with the date & your username of the machines. Along with what you might be looking for price wise. Especially as you are a new account here. Welcome to the SGUG forums! Hopefully you have other Irix machines too, and can stick around a bit.

Thank you for the welcome!

The two Tezros are unfortunately the only Irix machines that I have. I also have numerous NeXT pizza boxes (not for sale), some SUN and HP Apollo. All my machines except for the Tezros have been fully restored (all electrolytics replaced, etc.). We used Irix machines at work (not in my group) for complex systems simulation using Matrix-X, but they were mostly O2s and Octanes. I am still struggling with the concept of letting the Tezros go, maybe I will just sell one of them.

In the mean time I will start posting some information in this thread about both machines...

This machine has better condition plastics, Dallas that's still keeping correct time, and is the one I'm most likely going to keep if I only sell one.

This machine has more scuffs & scratches on the plastics and weak Dallas that slowly loses time and therefore needs replug to start L1. This is the one I'm most likely going to sell if I only sell one.
