The recap itself is easy, but the board repair if traces have been eaten away is often extremely challenging on these.
You do not *need* to recap the PSU but it’s advisable.
Yes, those are the correct part numbers for the K63H and L88M masks.
E42K is MC68040FExx (no suffix)
E31F is XC68040FExxM
Genuine chips also have their speed rating printed under the part number eg ‘66/33 MHz’.
Here are some examples:
Yes, this is correct - no FPU.
A valiant effort OP -...
No, it's not like that at all.
Part I used is TDK PS1240P02BT.
Here's a video I created of my ZuluSCSI, it sounds the same on my BlueSCSI V2 PowerBook editions:
Hey, the piezo buzzer works fine. There's not much I can say about it – it's a cheap solution that does the job if you want audible feedback for disk access.
The schematics indicate the Beige’s MFM floppy footprint is connected directly to the Heathrow chip. There is no empty controller chip footprint like on the Tanzania board.
Here is a comprehensive PDF guide I put together that will be useful for anyone wishing to take apart their Quicktake 100 or 150 for recapping.
I am maintaining a BOM on Mouser.
I wasn't sure if this should be an Article or Document, hopefully I made the right choice.
Please don’t hot plug SCSI devices - it’s not designed for that and you could do serious damage.
BlueSCSI won’t run off the back of a PowerBook as it doesn’t provide the termination power needed. You might be able to plug in a USB cable to provide power that way?
Just to say, as an IWII owner I’m very excited to see this project in development. Is the plan to combine the features of both the AppleTalk card and the memory expansion card that were originally available?
