Well, let's not go overboard on this `old machines' bit. At least
in my part of the world, RAM prices have plunged for 72-pin SIMMs,
but not for 30-pin SIMMs. A 16MB 72-pin SIMM is $130 (Canadian
dollars) or so; four 4MB 3-pin SIMMs run about $240. So let's do
an upgrade comparison, starting with a low-end 486 motherboard,
8MB of RAM, and an Adaptec 1542, and make a nameserver for an ISP
or other medium-size site out of it:
8 MB RAM Free
24 MB RAM (6x 4MB 30-pin SIMMs) $360
(24 MB of 4MB 30-pin SIMMs)
SCSI controller Free
New PCI motherboard w/ SCSI controller $175
32 MB RAM (2x 70-pin SIMMs) $240
Resale of old components:
8 MB RAM ($60)
SCSI controller ($80)
You should be able to sell the parts above at the prices I've given
above in no time. You've now not only gotten around the bounce
buffer problem, but saved yourself $125 in the process.
