The Sanyo MBC-55x-x series are all the same for the most part. The 550
is a single sided, single drive unit, the 550-2 has a single double
sided drive. The 555 was 2 single sided drives and the 555-2 was dual
double sided drives. These numbers applied only to the item as shipped
from the factory, the model didn't necessarily change when the owner
added or changed drives. NRI included these machines with their master
course in microcomputers & microprocessors, right after the Tandy TRS-80
model 4D wa phased out. They were great people to offer students a cost
reduced second drive, even though the box it came in from the factory
showed the unit as a dual drive to begin with. I believe all they did
was order a ton of second drive bay fillers and take out the second to
resell to the dumb students at $100 more. Imagine a $100 tag onn a Teac
FD-55B! What a rip when I dump dozens in scrap or donate many of them.
Whe I do sell them I get roughly $2 to $5 each dependant upon condition.

Answer, yes the silver keyboard with black keys and no ALT will fit any
of the MBC-55x-x units, also known as the "Silver Box" (not by me
though).

The serial port add-on was an 8251 UART, not the standard 8250 for
IBM/compats so patches are needed for communications programs. There is
still a BBS with *some* of the patches and anyp MBC-55x programs, called
the First Sanyo Opus. The number is (412) 856-1428. Should still be up,
called it just last month and it was. You have to look for the Sanyo
specific files area.
