I have a 5110 cpu unit but had to leave the drive unit and printer behind :(
If you can get the 5120 it would be a great find for your collection. The
data storage could be either 1.2 M or 2.4 M on the 8" floppies. The machine
was announced in March of 1980 and was the successor to the 5100 and was
based on the 5110 Model 3. Also Basic and APL are in ROM. Good luck with it.
