PRODUCT NAME
Retina BLT Z3, Hardware v1.0, Software 2.1.
BRIEF DESCRIPTION
24-bit, Zorro III graphics card.
AUTHOR/COMPANY INFORMATION
Name: MacroSystem Computer GmbhH.
Address: Fruedruch-Ebert-Str 85
58454 Witten
[Germany, I assume]
LIST PRICE
I have no idea. I paid 4800SEK (Swedish krones, check current value
rates as US$ changes quite often) + Postage & Packing.
Bought from DELIKATESS-DATA AB, tlf +46-31-300 580, FAX: +46-31-302
983. They provided me (and others) with truly excellent and fast service
and are highly recommended.
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
An Amiga with a Zorro III slot (i.e., A3000 or A4000).
At least 1 MB Chip RAM and 2 MB Fast RAM.recommended.
4 MB Fast RAM would be better.
Hard drive recommended (for large images).
The manual states, "A cheap VGA monitor is recommended, while
Retina can only be brought to its limits by using an
enhanced monitor, such as the NEC 5 FG or similar."
SOFTWARE
AmigaDOS 2.0 (from Kickstart V37.175, WB 37.67, onward).
The manual states "please do not use unofficial beta
versions".
COPY PROTECTION
None.
MACHINE USED FOR TESTING
Amiga 3000/25, 4MB Fast RAM, 2MB Chip RAM
Softkicked Kickstart 40.62, Workbench 40.29.
INSTALLATION
The software uses the Commodore Installer program. Everything went
smoothly.
The card is approximately 3/4 length and installs in a Zorro slot
with a little trouble (but no more than other cards). Why do they always say
"use light pressure"? So they won't have to replace the card if it breaks
after I almost had to hammer it into the slot? "You didn't use light
pressure now, did you?"
I had of course read the manual before doing anything. The card
arrived the day before an exam, so I just browsed through the manual during a
study break and felt well prepared. I had configured the "RetinaEmu"
program (which is SUPPOSED to take care of stuff) so it would output to the
Retina card instead of the Amiga, as it said in the manual.
So, happily I switched on my Amiga. It took some seconds before
Kickstart was loaded, etc. I didn't see anything on the screen (my monitor
told me Retina wasn't sending any understandable signal), but I was not
worried. Anyway, Kickstart had loaded and I was eagerly waiting for my
8-bit Workbench to turn up. At this point my monitor told me Retina was
sending 31.5 KHz and 59.5Hz, the mode I had used until I got the Retina. I
waited and waited, but nothing happened, so I rebooted. and thought I'd try
again. Same thing. So, I switched of the machine and let Kickstart load
again. Same thing.
I was now getting a little worried. (Defective card? No.) So I
actually started to read the manual (like I'm some kind a lamer :-)), but
I couldn't find anything useful.
So I switched the monitor cable back to the Amiga output and
rebooted. There! Now I knew what was wrong: my Kickstart was not yet
supported. It was released by Commodore to developers almost a year ago,
and it says "08/16/93" while the Retina software is at most a month old
judging from the date on some files. So, I pressed the gadget which says
"OK" below the "Kickstart not supported" crap, with the effect that after
some seconds the screen went black.
Hmm..., I said to myself. I found out that the genius people at
macroSystem (not) had found it smart to let that message pop up BEFORE
switching the display to Retina (clever, very clever). Thus, the requestor
was logically being displayed but the screen was blank. Now, since it is a
little difficult to see this button and click on it without a display
(remember, we only switch the display after clicking "ok") to look at, and me
now having 1 monitor, and not wanting to fry it by changing the plug from
Amiga to Retina with the power on, there was a problem.
Luckily, just some days ago I had read in some old documentation
that I can press Right-Amiga V to cancel (or was it retry? :-)) a
requester. That actually worked, so after some more fiddling with monitor
cables and a shower later, I could actually watch my first output from the
Retina. Stunning (not).
I am not exactly sure what it means that "RetinaEmu" doesn't support
my Kickstart "yet" (its been a year since it was sent out, about time or ?).
Perhaps it means that I can only use a certain number of colors (since WB
does turn up)? No, not exactly. It seems it means that the Workbench
windows will only be displayed in ECS number of colors. I tried it out and
switched to 2 colors (in Amiga prefs) which made the windows use only 2
colors, but the icon were still using more colors (i.e., an 8-color icon
looked just fine on the 2 color Workbench), so I am not sure what it
means....
Well, now I started to configure for my monitor. The documentation
says it defaults to VGA output. There were many monitors, but no MAG17, so I
deleted all of those useless monitors and created my own entry for my MAG.
After this was done I started up "define monitor", which lets you define
various resolutions for the monitor (when creating the MAG entry you can
only type the supported Horizontal KHz frequency and the Vertical Hz screen
update rate).
This program was actually OK (not like the crappy others) and lets
you optimize for your monitor pretty well (has a test picture even,
stunning!). After having created some suitable X x Y resolutions for 8, 16
and 24 bit (which you have to append to a temporary file) I had to use
another program to "append" my new resolutions to Retina's own private
gfx.base thing. This does not always (often) work, having created a nice
1024 x 768 in 83Hz entry, this did not show up anywhere, so I am as of now
limited to 76Hz (Which I defined previously). The program tries to
calculate for instance what the KHz frequency will be if you update Hz from
70 to 80. In my opinion, the only decent program here.
REVIEW
Having played a little with the tools which came with the Retina,
which all have "liesmiech" files, (since I don't know German, it doesn't
enlighten me), I thought I'd get down to business. So, I loaded
"RetinaDisplay" which brought up an appicon (drop image files onto it, and
they will be displayed) and a requester where I couldn't select more than one
file at a time. I opted for using it from CLI (which I do anyway). It shows
some options when you type "?" for the filename. Apparently, these options
are explained somewhere else (where?).
Now I was ready for business. I changed directory (using Eivind
Nordseth's excellent "qcd" program -- get it from Aminet now! Yes, Eivind
paid me to say this... not!) and tried to display some image files. I
aliased "rd" to "RetinaDisplay", typed "rd erika#?", and got a stupid error
message. Apparently the program does not even support wildcards. So, I
typed "rd `dir erika#?`", using the backquotes and "dir" to expand
wildcards. This of course worked, kind of. RD decided to switch from the
1024 x 768 I was using to 800 x 600 which made my monitor produce a rather
loud "ZonKKkk". Anyway, I didn't care for that, Erika was on my screen, then
some seconds passed and another erika picture was on my screen, and so on....
This program is so cool, it does NOT allow scrolling, does NOT wait
for me to say "next picture" or anything. It just displays the pictures as
fast as it can (some pics take 10 seconds, and others 1 second, so I never
see the 10 second picture if there is a 1 second picture following directly
afterwards). Also I cannot make rd display the pictures in any particula
