REVIEW OF AN AUSTRALIAN 2 MEG RAM EXPANSION BOARD
It is a welcome change to be able to review a locally produced
product which holds its own against the imported variety - "import
substitution" as Mr Keating would have it, and let's hope there's a
lot more of it, if only for the improved prices.
PROTON MICROELECTRONICS is the company responsible, and they are
based in Adelaide. Their range of RAM expansion boards includes 512K,
1024K and 2048K versions. The one I have tested is the 2 MEG (or 2048K)
and it is a Non-autoconfigure board - I am assured by Proton that their
AutoConfigure versions (for 1.2 software only) will be available
anytime now, for $95 extra on the prices they are currently
charging. Proton also assures me that the boards are compatible with
Sidecar (and they are, by a recent test), and that the boards
are designed to chew up little power due to their "Low Power CMOS
Design", thus allowing 4 of their 2 MEG boards to be added to the
side expansion port of the Amiga, giving a remarkable 8 MEG and more!
Having had the extra 2 MEG available for some time now, it isn't
too hard to find a use for so much RAM... it
is remarkable how memory demands rise to meet availability, and, e.g.,
people who want to create symphonies of sampled sound will find ways
to use such quantities.
Installing the unit was a simple matter of pushing it into the
side expansion port (with power off); copying the two commands ADDMEM
and MEMINSTALL into the C directory of the boot disk; and adding the
command MEMINSTALL in the startup-sequence in the S directory. Booting
up then shows a message saying "some expansion memory found" and it's
all available for use. If you happen to have a Sidecar, your startup-
sequence will say Meminstall -Sidecar, and if you've had the "Kickstart
in ROM" upgrade done, you'll type in -kickram as well. The board
also comes with an optional clock, worth getting so that you can
forever forget entering the time and date. Note that all the above
will be unnecessary if you buy the Autoconfiguring version - the 1.2
software will handle it all for you.
The appearance of the unit is neat and pretty compact - it is
beige-coloured, practically the same as the Amiga, and when sitting
in the port rises about 3 cm above the CPU, and extends from behind
the joystick port to the back of the CPU. It's housed in a metallic
casing, and of course has a Pass-Through Bus connecting up more units.
An inspection of the innards of the board by a friend who is a
computer engineer revealed solid workmanship in the construction.
The documentation which comes with the board, both on paper and on
a disk was quite sufficient to understand what to do with the thing.
Another option provided is an Analogue to Digital Converter for those
involved in more technical pursuits, and a 6 month warranty is
also provided.
So those are the facts, but is it worth getting? And how does it
work in practice? The best use for such a board, in my opinion, is
for setting up a "Recoverable RAM Disk" (RRD). The great virtue of
such a device is, as its name implies, that if the computer hangs, or
you get a Guru, you can re-boot with the same boot disk and everything
that you had in RAM is still sitting there, blithely unaware of any
crash. This makes you feel warm and secure, since you can use the
speed of RAM without its transience. So, for example, I load my full
customised Workbench into RAM (or the virtual device VD0:, to be
precise), remove the actual disk and carry on as before with much
greater speed, and with a disk drive freed up. And since the total
RAM of the system comes to over 2.5 MEG, there is still about 1.6 MEG
available for other uses. A company called ASDG in the US has made
available such a RRD on Fish Disk 58 as shareware, and it works very
nicely with the Proton board. Such a set-up would also work with the
1 MEG board with room to spare, and if you got the half-MEG board
you would probably make a slimmed down RRD with just the basic
commands and libraries.
As noted in the documentation, there are some programs which
don't run with Expansion RAM, notably Deluxe Paint I, which uses
"Chip" memory (your original 512K of RAM) exclusively. Most programs
are fully compatible with expansion RAM however and will look for it
and use it if it's there. I noticed that a couple of little utilities
had problems, for example the "ChangeKickStart" utility, which allows
you to change your Kickstart disk over without turning off the
computer. On the other hand, I loaded the entire PageSetter program
into RAM and found that performance was much improved, especially
the speed of refreshing or changing of the display.
All in all, considering the facts that these are Australian
products of good quality and very competitive pricing, and that the
addition of more RAM makes your Amiga purr with pleasure and speed,
I would recommend these boards highly. If you want a little more
ease of installation, wait perhaps for the Auto-Configuring versions.
But if you're finding that you're beginning to reach the limits of
your 512K fairly regularly, consider such a purchase. The Amiga was
made for it, especially since it's a multi-tasking machine, and
you'll find quite a leap in performance. Of course, my problem is that
now that I tried it for review purposes, I couldn't do without it, and
had to fork out and buy it.
