This was what I had to contend with whilst closing up the case - it's tight, as I've not left much give in any of the thicker cables (by design) but it all goes in there lovely.

I thought I'd created issues with the HDD and FDD LED's at one point, but for the HDD I'd managed to disconnect the cable at the SCSI2SD end, and the floppy issue was technically non-existent; it only lights for DF0 not for DF1 and upwards - makes sense I guess, as there should only be one internal floppy drive lol :D

Thank you sir :)
Really nice Custom Project. Great! (y)

Some real progress today - I've started installing OS 3.9 from the original media in the internal DVD/RW; I've been trying to keep things as authentic as possible given that I installed Workbench 3.1 from original floppy media too lol

Ran into an issue trying to install Boing Bag 1 though... Installer related issue it seems - will post more once I've had a chance to look at it on Monday :)

My underlying OS was the issue with BB1 - I had a copy of installer 43.3 in C: so it was using that instead of SYS:Utilities - deleted it and all was well. This is where I am now:

OS3.9 with BB1 through 4, CyberGraphix 4 and all the associated goodness that I got through following Chucky's guide :D

But she does get rather toasty... I'll be doing some airflow and heat analysis soon.

So... I made some changes to the direction of the fans in my Miggy...

So the fan from the BPPC sucks air in from under the machine, and blows it towards the top of the case, and the two smaller fans at the top suck air up and out of the case.

On_20_mins_-_Front.jpgOn_20_mins_-_desk_gap.jpg
After 20 mins, the machine rapidly heated up to 36.2C - heat from the BVision mainly, and the desk gap having risen to 29.0C; at boot I started the PPC version of the Warp3D demo to keep everything I could busy.

After_2_hours_-_Front.jpgAfter_2_hours_-_desk_gap.jpg
After an hour it reached 38.0C at the front and 32.5C at the desk gap - and another hour later there was no change :) So temps stable!

I did find that inserting an optical disk could cause the machine to reset if it is heavily burdened - I suspect that's because I have it being powered directly from the board. In the future I might look to power it from the same loom powering the floppy drives, as that's effectively from the outside direct.

Found a little time to alter the DVD-RW power - hopefully will get some time to test over the next few days to see if it has improved stability :)

I'll be fitting a fan here too, blowing inwards sideways attached to the top of the case to cool the Indivision

Thank you kind sir :)
Superb :) nice project

Tested the drive, and it's stable now - doesn't cause the machine to go into a coma when loading a disc whilst under heavy BPPC/BVision load :D

Here's how I tidied up the power mod:

And here's another little alteration to prevent the use of the external floppy port (it's removable) - as with DF0 and DF1 internally, it does strange things if you try to plug in an external drive!

Got all the fan fittings done, now need to order machine screws the right length, and make a power connector for it :)

And the fan is now fitted properly - just need to run power for it now! :)

And done! The top is actually finished now... Just a RapidRoad to obtain and fit into the bottom :)

Hi all,

I'm still having issues with running Wipeout, but I've a few things to try still with that. In the meantime waiting for new hardware to arrive, I decided to see if I could get it to boot a bit more quickly. I changed my Startup-Sequence to use BlizKick instead of SetPatch to load the ROM changes to 3.9 - for prosterity, I changed the first section to:

Blizkick * EXTRESBUF=165000 HOGWAITBLIT SpeedROM MODULE BPPCFix BPPCFix040 BBlank NewAlert ROMFIXES SpeedyIDE NoClick MoveVBR FixMath404 MuMove4k FixGetMsg scsi.device FastFileSystem Filesystem.Resource console.device Ram-Handler romupdate.idtag shell Bootmenu exec.library NOPUPREBOOT KEEPEXEC QUIET
SetPatch NOROMUPDATE QUIET


Anyways, new hardware has arrived:

53713_F24-83_D1-4387-_BD98-3_CC21_EEAAD96.jpg


Which will fit here quite nicely:

073_BFABD-875_C-4594-_B004-7_A45_F01_DB086.jpg


And I've now modified the USB cable to fit under my SCSI cable off of the rear of the BPPC - just need to make holes and fit :)

And I discovered why the CD Audio wasn't working...

lol - will get to work on fitting the RapidRoad properly soon

More installation stuff today, put some blobs on the RapidRoad to make it stay put when the machine is assembled - the long blob on top squished down when I reinserted the keyboard:

0_E4_C7_A20-9993-4_DAC-9_A29-4_C4_C8_C8_E57_DB.jpg


I altered the clock-port cable to make it more amenable, I also re-routed the CD-Audio cable:

22_DDCA4_D-_DDEA-45_F7-957_D-4_D7_F1_E043_CF1.jpg


Sugru'd in the USB ports once I'd opened up appropriate spaces; I used the same horizontal positions as marked on the case, but closer to the bottom:

22_DDCA4_D-_DDEA-45_F7-957_D-4_D7_F1_E043_CF1.jpg


The RapidRoad sits nicely where I want it to stay, and doesn't move when the keyboard is in - still removable though!

72_B1_D7_C3-_F618-4701-_ADF3-3_BEEE29_CABE8.jpg


The USB ports look good from the outside too:

FCE1_FBCA-4_EDF-4147-_A30_D-15779891316_C.jpg


Just need to hot-glue the USB cable into place tomorrow so that I can reassemble for a while again - unless the SD card extension turns up, in which case I'll fit that too :)

Aaaaaaaaaaannnd it's all in :)

Works lovely too - unfortunately I've discovered that some of the memory on my BVision isn't as it should be. Looking to find someone that can replace it (the memory) - might pick somewhere it hasn't travelled to yet; it's certainly more travelled than myself! Edit: After a trip to Hese, it's now working exactly as it should :)

Another little mod today - fitted a MicroSD to SD extension to breakout the SCSI2SD card to the rear:

CC106_AE4-6_C46-4_FEA-9088-2_A02751878_C9.jpg


Which looks pretty good at the rear too:

Should save me a lot of hassle when I want to back it up! :LOL:

In the quest to improve boot times on my Amiga, I'm now looking to have a custom set of ROM's made. Currently every reboot (I think there's still 2 or 3 during boot at the moment) there's a 20 second delay whilst it decides that there's no bootable device on the IDE. Dropping scsi.device from the ROM's altogether should sort that, maybe including atapi.device instead and maybe the Poseidon bits too.

You can also use an IDE terminator to minimise IDE (lack of) detection delay.
