1200 Laptop Project
I started this some while ago but had to put it away for a while but now it's back and is almost finished.
A few years ago I built an A600 as a sort of laptop albeit very heavy in a homemade sheet steel case. It worked but was a bit flaky and rattly. This time I decide to go for a 1200 but use a brief case as a case to make it a little more portable. The specs of the machine are: 1D4 motherboard Apollo 040/40 accelerator with 32Mb RAM Eyetech SD/FF Eyetech 4way bufferred IDE Eyetch EZKEY keyboard adapter Slimline CDROM with ATAPI/IDE adapter Slimline PC(laptop) floppy with adapter with just pins 2 and 34 crossed on the cable 4Gb CF card with CF/IDE adapter for the hard drive PCMCIA CF adapter for file transfers PCMCIA wireless card PCMCIA ethernet card Shuttle PSU Slimline PS2 keyboard Synaptics PS2 trackpad from a dead laptop Cocolino PS2 mouse adapter Switchable external amiga mouse port 12" desktop LCD screen stripped out for the display with inbuilt speakers and amp CU Amiga CDDA mixer to mix CD audio with the native audio The mother board has been modified with the PCMCIA reset fix from aminet and the PCMCIA LED fix found here on EAB courtesy of doobreynet and the modulator has been removed. Here are a few pics, as requested. http://i186.photobucket.com/albums/x...a/DSCF8184.jpg This is the PSU cabling. All it has now is a standard MOLEX connector to feed to the motherboard, a floppy connector which feeds a power distribution board, a connection to the ON?OFF switch and an earth connection. http://i186.photobucket.com/albums/x...a/DSCF8182.jpg This is the mouse connection. The external and internal connections on the cable have the power and gnd lines switched to select either the internal track pad or the external mouse/joystick. http://i186.photobucket.com/albums/x...a/DSCF8175.jpg PCMCIA LED mod http://i186.photobucket.com/albums/x...a/DSCF8185.jpg CF card harddrive http://i186.photobucket.com/albums/x...a/DSCF8187.jpg Fully fitted lower case. Watch this space! More photos to come! |
Hi!
Thats a really intersting project, thanks for sharing :great Hope you got a big Lap though :D Only kidding, I look foward to the finished project and the updates :cool One question, I guess you'll mount a keyboard on top? Have you thought about cooling/venting? Steve. |
I can recommend you using an A500 keyboard with the LED sacked out. Wiring +5, GND, kb_clock, kb_data & reset lines will be a breeze for one with your soldering skills.
Just swapping the key tops with the one from A1200 and all will be perfect. Or go nuts and paint the keycaps black and add black Amiga stickers over. Oh, I concur with Steve on the cooling matter: better grab a proper cooler as the 040 is a hot monster. |

I've had it fully closed up and running for over 4 hours without any over heating problems. The fan on the 040 is bigger than the original and there is draw through ventilation from the front of the case near the carry handle and out through the PSU at the rear.
The keyboard is a slim line desktop PC thing, PS2 converted to amiga with the EZKey. |
Awesome!
Moar pr0n! Moar! |
It's finished!! More pics tomorrow!

cant wait to see the finished project mate

<Sits tapping fingers> :D

Finished the laptop yesterday, well, finished for now, there are still some improvements I want to make, USB support for one and change the PSU for a battery and Pico PSU and charger cct, but that will come in due course.
Here you are then, a few piccies of the "finished" thing. http://i186.photobucket.com/albums/x...a/DSCF8337.jpg Overall shot http://i186.photobucket.com/albums/x...a/DSCF8338.jpg View of the keyboard and track pad. The 4 screws allow easy access to the guts of the machine. http://i186.photobucket.com/albums/x...a/DSCF8340.jpg Screen view. I used Bloodwych's ClassicWB OS3.9 as a starting point and then tweaked it the way I wanted it. The backdrop is a MAC backdrop which I used to create a pattern for the dock. Only problem I have is I have not found a way or removing the border from the dock. Anybody got any thoughts on whether it is possible? http://i186.photobucket.com/albums/x...a/DSCF8342.jpg CD and PCMCIA slot http://i186.photobucket.com/albums/x...a/DSCF8343.jpg Floppy and power http://i186.photobucket.com/albums/x...a/DSCF8345.jpg Rear connections with the external mouse / internal trackpad switch next to the mouse port http://i186.photobucket.com/albums/x...a/DSCF8348.jpg http://i186.photobucket.com/albums/x...a/DSCF8349.jpg http://i186.photobucket.com/albums/x...a/DSCF8350.jpg Some benchmarking screen shots. Hope you like it! I do!! |
Thats a nice mod! I wonder how slim you can go. Nice way of making the A1200 portable, gives me many ideas.. .hmmm :-)
