The SB180
Single Board Computer
Featured on the cover of Byte, Sept. 1985,
the SB 180 lets CP/M users upgrade to a
fast, 4" x 7 /2" single board system.
'
• 6MHz 64180 CPU
(Z80 instruction superset), 256K RAM,
8K Monitor ROM with device test, disk
format, read/write.
• MinI/Micro Floppy Controller
(1-4 drives, Single/Double Density,
1-2 sided, 40/77/80 track 3'12;' 5114"
and 6" drives).
• Measures 4" x 71f2~ with mounting holes
• One Centronics Printer Port
