Well, usually nobody wants that, too common and no demand.

If they are original IBM systems, then I agree. If they are clones, I
usually salvage the drives, perhaps the I/O cards if they are exotic.
Otherwise I'd junk them, you'll drown in those systems otherwise.

Eh, I even have some Ultra60, Ultra80 and Ultra10 that nobody wants. And I
definitely don't want an Ultra1 for playing (we still have some in service
here, but they're not really fun). I'd prefer the older sun[1-3] and
sun4/sun4m. Small UltraSparc systems are really dirt common. You can be
happy if someone takes one for free. Don't expect any money.

This is from the 1987 edition of Computer Review:
"Introduced in 1980, the Philips P4500 is an interactive business computer
system designed for small business distributed-processing networks. The
P4500 employs 'team processor' architecture, which delegates functions
usually performed by the CPU to dedicated special-purpose processors. ANSI
COBOL is the major programming language under the DINOS 4000 operating
Then further on:
"Word size: 16 bits, Memory: 256 to 1024kB MOS, Memory Cycle Time: 563ns
Magnetic Tape: P3540: 1600bpi, 37ips
Line Printer: P2910/62/65:100-600lpm
Serial Printer: P2931:100cps;P2934:300cps
System Software: Real Time Monitor, Batch Monitor, Data Base Sys,
Operating System: DINOS 4000
Sold primarily in Western Europe"
I'd be curious what the CPU is.
