Well, it's a matter of modularity. I like
compactness to a point,
especially if I'm trying to make something small. But if I want
reliability, I'll use separate USB and Ethernet PHYs.
I haev never understood this love of making thigs as small as possible.
OK, I don;t want a pocket calcualtor that actually takes up a 19" rack
cabinet, but for soemthign that I don't have to carry about, I don't care
if it's a half-rack-width thing, a 3U rack module, a 6U rack module. etc.
In fact things that are too smal lare often difficult to use because the
cotnrols are too close together. Iam not even going to mention repairing
them..
In a differnet context, I much prefer the handling of a Nikon F camera
over an Olympus OM series, for similar reasons. Things can be too small
to handle easily.
[1] Although not always. The serial port in my
HP9817 was defective when
I got the machine and I found that not only were the buffers damaged, so
was the 8250 serial chipe (yes, an 8250 in a 68K machine. Odd...). I am
not sure what had happened to the machine.
Odd indeed. Lots of 68K machines used 8350s, but that's a very
different chip.
What's an 8350? Do you mean Z8530 (the serial chip used in older Macs),
ro is this some other device I've not come across?
The HP9000 serial ports (both built-in and on plug-in cards) did use
8250s -- the chip used in the IBM PC -- for some odd reason. Well, there
was a nice microprocessor-controlled serail card that used a Z80A CPU
and a Z80A_SIO serial chip, but then the serial chip wasn't on the 68K
bus. The HP Integral used a 68000-family serial chip, the number of which
I;'ve forgotten for the moment, but can trivially look up.
