My 500+ Project

[djos]

I really liked the style of the power board i'd bought but have decided to give one of the below style pico-psu's a shot - on the plus side, they are tiny and cheap!

Good to hear, the nice big solder pads on the PCB should make life easier too. :cool:

I got Lazy today and ordered an Amgia/pico-PSU adaptor.

$20aud shipped and less hassles = a good deal imo :cool:

I also have Kipper2k's rev5 autoconfig 8mb a500 ram board arriving soon - It has a second socket which will allow me to move the IDE68k away from the keyboard and especially the CPU as i've found having an IDE cable draped across a CPU = overheating after about an hour. :p

[djos]

Kipper is selling them via AmiBay and his own site:

This is the PCB for the Rev5 Board:



I intend to install my IDE68k into the horizontal socket above the Ram.

I know, I just can't start another project now when im not even finished with my A1200 So by the time im done maybe ill see the ACA500 and ACA1220 for the A500

yeah I know what you mean, I intend to get an a1200 for my next project but funds and SWMBO wont allow me atm and my a500 isnt finished yet either! :S

[djos]

Lol, I completely agree!

[djos]

That is nuts!

PS, I take donations.

[djos]

I must say a 1084s would sure be nice. :cool:

[djos]

What would shipping to lil old Adelaide for a 1084s cost?

[djos]

Lol, RoadTrip!

[djos]

I have Lurch to thank for me finally getting hold of a rev8a replacement board making my 500+ a real 500+ again (when it arrives)! :cool:

In a couple of weeks I'll have a full ECS Rev6a PAL a500 board for sale if anyone is interested - I can also change it to NTSC with a solder blob if desired and it has the chip-ram mod to convert trapdoor to chip-ram. If you are interested PM me.

[djos]

Who am kidding, spare it is!

EDIT: my pico-psu and adapter showed up today and they are tiny and will work great - I hope to install them into and fire up my external PSU/DVD combo tonight and maybe test out my sata ideas too.

[djos]

Arggh!! My luck with tiny power supplies seems to suck, I think my 12v 10a power brick is either faulty or not delivering enuf juice for the pico PSU and as a result it doesnt work!

I hooked up a trusty old full ATX PSU to my PSU-Miggy adapter and everything works fine so im confident my wiring is good.

[djos]

Well ignoring my PSU project issues, i have had some success finally getting my CF-IDE to play nice and operate at decent speeds etc (PFS3 was the answer).

I've also changed Kickstart switchers to an all-in-one unit which will fit under Kippers 8MB automount Ram board I have on order (other one I have is too tall as it sits in the socket with both roms mounted on top).

New KS Switcher/ROM and CF-IDE Installed: http://dl.dropbox.com/u/71121999/Amiga/2012-09-15%2010.21.58.jpg

Installing ClassicWB (actually works now): http://dl.dropbox.com/u/71121999/Amiga/2012-09-15%2010.24.54.jpg

One issue i've come across, that I can replicate in WinUAE too, and is a PITA on my real miggy is with the non-automount ram board from tomthul; ClassicWB boots up perfectly without the autoaddram command in the S:startup-sequence file, but If i put the C:autoaddram command into the S:startup-sequence file I get an "intuition is trying to reset WB" error and when WB appears my icons are the wrong colour.

It doesnt seem to matter where I put the C:autoaddram command either, I still get the error, the only time I dont is if I run autoaddram after WB has finished booting with results in bugger all chip-ram left and WB is a lot slower because it's not in fast ram.

Any Ideas folks?

[djos]

Can you please copy n paste your startup-sequence here so we can see what you do/don't have??

Az

Here you go:

I tried putting it right at the end just before the "C:LoadWB" command and that so far is the only place that doesnt seem to cause the issue - It does result in only 300-400k of chip-ram left.

[djos]

Thanks Az I'll have a play and see what happens.
