[Info-vax] terminal servers etc

[F H]

For those who want to find a DECserver 90M on eBay or somewhere else:
please note that not all DECserver 90M terminal servers have a flash
memory card present!

There are two or even three types of 90M devices:

- Those without a flash card. They can be recognized by the absence of
an inscription on the front panel. They rely on MOP to download their
OS.
- Those with a 1 MB flash card. They have the inscription "1M Flash"
on the front panel. The OS is on that flash card but it takes several
minutes to decompress the OS on the flash card into memory. They will
download the OS over the network only when a special procedure is
followed at power-on time.
- It seems that a version exists with a 2 MB (or more) flash card.
This system boots stand-alone too and very fast because there is no
decompression to be done. I have however never seen this version.
