:>Why don't you add a, possibly used, A500 of A1000?
:And more memory and another hard drive, and possibly second copies of a lot
:of software, to satisfy the license agreements? No, for a 10-15% duty cycle
:(if that much) I'd much rather use one machine, multiuser. Anyway, two users
:on a LUCAS/FRANCES Amiga ought to get better individual performance than two
:on plain Amigas. (Assuming I do the LUCAS/FRANCES hack, which I'm strongly
:considering...)

Now that I have NET: working w/ my parallel port network (raw
throughput of 28KBytes/sec), having a second Amiga has suddenly become
useful, much more useful than spending the $$ for an accelerator.
A year or two ago I bought an A500 to complement my A1000. The
purpose was to have a second computer to play around with networking
and to have a second computer to debug things on. Apart from that
it was pretty much useless with only a floppy drive. Monitor? oh yah,
I use an old 1701 monitor on it from my C64 days.
Now here comes along NET: (Doug Walker), and just when I've gotten
my parallel port networking code to work!. Doug got a taste of the
match made in heaven after getting NET: to work with my ppn stuff,
but he was using an Alpha version which had bugs so it died after
a while.
But, fortuitously, Doug posts the NET: source and I am able to get
it up and running w/ the latest ppn code. No bugs, diskperfa comes up
with impressive numbers, and now the A500 has access to all my A1000
volumes, and at a decent speed. Not only can I do all the things I
normally do on my A1000 on my A500, but the enviroment setups are, well,
you can't really tell the difference between the two. To get things
compiled in a hurry I can compile on both machines at once!
The moment I get permission from Doug to post the parallel port
NET: binaries I will do so. (This'l probably take Doug by surprise
as the whole business has occured only in the last 3 days!) Note:
cabling is not the same as was for the Alpha I sent out.
diskperf results (NET: to my HD. Btw, I have a *slow* hd. numbers
probably better with better hd's though the network limit is 28KBytes/sec)
create 10 files/sec, delete 21 files/sec
dir scan 18 entries/sec
seek-read: 30 seek-reads/sec
r/w (512) 12483 bytes/sec (rd), 9745 bytes/sec (wr)
r/w (4096) 15887 bytes/sec (rd), 15065 bytes/sec (wr)
r/w (8192) 16384 bytes/sec (rd), 15511 bytes/sec (wr)
diskperf NET: to my A1000's RAM: drive yields 25 KBytes/sec
(4096 byte buffers). Raw network throughput is 28 KBytes/sec.
