CD32 Laptop

[Stedy]

Let's see,

I towered a CD32/SX32 once, had a few technical issues.

CD32 motherboard dimensions, approximately 285 x 150 mm by 20 mm high.

SX32 pro, 140 x 180 mm by 65 mm high at back panel. PCB + HDD, 30 mm.

My CD32/SX32 runs WB 3.5 fine, do not have WB 3.9 so can not try that.

It should wok with an IDE CD-ROM, you will need an IDE buffer though as the SX32 IDE port is not buffered properly.

My SX32 Pro, 030/50 MHz + FPU + HDD uses 2.19 Amperes @ 5V and 0.077Amperes @ 12V. Probably a bit too much for a battery.

The trickiest thing will be interfacing to an LCD display, as mentioned previously.

Oh the great website with CD32 tech into is:

See ya!

A possible but not necessarily cheap solution is to use this eval kit from Averlogic:

The Eval board comes with an interface card and a Samsung 15" XGA TFT screen.

The UK distributors sight is down so I can not get a price at the moment.

Me again!  :-)

@patrik:

I wrote a document on Aminet detailing Amiga PSU specs and power consuption,
http://www.aminet.net/hard/misc/psu-problems.txt

The bare CD32 uses less than an A1200 or A600.

My HP laptop battery supplies 14.8V @ 4.4A and last for upto 4 hours.

I can find 5" or 6" LCD screens with VGA or video inputs quite easily but expensive, around the 200UKP mark.

Another option is the LCD screen for the PSOne, again a 5" display. The connector to the PSOne is defined on the Hardware book and as a PSOne outputs PAL/NTSC, it should easily hook upto an Amiga.

Seek and ye shall find:

Pinouts and interface diagrams for a number of laptop LCD panels.

Most use a Low Voltage Differential Signalling (LVDS) interface. There are ways of converting from PAL/NTSC/VGA to LVDS, I have the details at work.

I did find LCD panels that took either VGA or PAL/NTSC inputs but the cheapest was $199.

I will gather some information from work and post again tomorrow.

To ACE:

I doubt you will need all the circuitry on the PSOne LCD page. For that application he had to take a composite video signal and create 2 sync signals and RGB colour information. The Amiga has 3 video sync signals (CSync, HSynv and VSync) + Anaglog RGB and Digital RGB data all on the 23 pin video port.

Maybe I missed the pinout but you should be able to hook a PSOne LCD stright upto the Amiga with no interface PCB.
I just checked the PSX video connector it has SVHS (not relevant here) and Component video, (Csync + RGB) all of this is on the RGB port.

If the display handles DVD fine, that is 728x576 pixels then most Amiga displays wil work fine.

Currently my A1200 is driving a Samsung SyncMaster 171S 17" LCD monitor quite nicely. It is capable of displaing 1280x1024 but as I have AGA, the highest mode I use is something like 728x536, in this mode the monitor stretches the pixels to fill the screen, there are no borders.

Good luck with the project.
