The collection has a few MicroVAX machines, and also some unusual boards from an Intergraph/VAX system that was housed at Wisconsin DOT (photos of the Intergraph boards have not yet been taken).
Also not shown are a couple of MicroVAX II machines in the larger, wheeled BA123 free standing cabinet with wheels. Both have dead power supplies.
This pair of MicroVAX II’s were “donated” to the collection when I got a call from a good friend whose mother worked for an outfit supporting medical records software (not Epic!). They were downsizing, and had a number of computers that they were happy to have someone – like me – tote away. I obtained an IBM RT PC and a couple of AT&T 3B2 computers at the same time. The IBM Series/1 mini wouldn’t fit in my trunk – or my basement – by that time.
The top MicroVAX II has a TK50 tape drive, the bottom one has a RX50 floppy drive. Below that, with the two white switches, are a pair of Fujitsu SMD disk drives that were still functional last time I checked.
This MicroVAX 3300 was obtained through the University of Wisconsin “SWAP” surplus program for a “song”. It has a tag declaring its obsolescence which meshes nicely with the one from Hannes’ PDP-11/20. It has:
- A KA640-BA CPU with a serial console and Ethernet
- MS650-AA 8MB of memory
- A KRQ50 special DEC CD-ROM interface (not connected)
- A pair of RF30 150MB DSSI disks
- An M3107 8 line asynchronous multiplexor (the unconnected multicolored ribbon cable)
- A TK70 tape drive (partially obscured by the green tag)
- A CMD Technology SCSI interface (connected to the CD drive on top.
