This documents the infrastructure on and in which I am working for this Retrochallenge. Readership is Public.


Figure 1 shows the major units in the infrastructure and how they are networked together physically.

The main items of Retrochallenge interest are highlighted in purple. They are various kinds of MicroVAX, though the ones in the green boxes are SIMH systems. The key elements are

NAS devices. They are my most active backup devices.
PC architecture systems running NT6.1. WINTER is a new, passively cooled machine that I intend to run continuously and host at least one SIMH system so I have VMS always available.
An old PC running NT5.0.
An Alpha PC 164SX machine running NT4.0 obtained in 1998. I really wish I'd gotten an LX, then I could run VMS on it, but I'll think of something interesting to do with it one day. I say more about ECHOES in this document I wrote during the 2016/01 Retrochallenge.
AH120, AH6, AH132
AH120 is a Netgear Router/Firewall/DHCP server/NAT decvice, AH6 is a Gb switch and AH132 a 10/100 Mb switch.
AGARIC is an HP laptop PC and BLEW02 is a 2007 vintage Macbook that runs NT6.1.
A MicroVAX 3100-40.
A MicroVAX 3100-30 and VAXstation 3100, not yet in service.
An AXP-150 PC which used to run NT4.0. It was my main system from 1995 until 1998 when its video card failed and I had to migrate to ECHOES. I plan to see if I can run VMS on it now.
An Infoserver 1000. I have a SCSI expansion cabinet with various devices installed, plus a few SCSI disks. I intend to make them useful via the Infoserver.

Currently, my main VMS systems are MEDDLE and AGAR30. But I don't keep them running all the time. My aim is to use WINTER to host an always-available VMS system.
