Not really 'classic computing' or'retroware' purely in or
by itself, but it can certainly be a great addition!
I have anice, compact, Cisco ASA 5505"security appliance"
(read: an IOS hardware firewall)here, maximized memory
(1-Gbyte, so enough for the latest firmware), 4-Gbyte fast
CF storage, with a Cisco RJ-45/UTP<=>serial cable included,
also the original paperback documentation and the device
is fully licensed. (For any specifics, pictures and such,
contact me.)
It's a great device to secure and filter traffic going in
and out of your collection of older systems, so you won't
have to worry as much about vulnerabilities and so forth.
It's located in the Netherlands.
