It's been a while since I worked on this one, I could never got it working reliably before but one small bodge later and it's looking more positive!

It's from a very uncompleted schematic I was drawing form my repro PCB, I got about half way through then got distracted and never got back to it, one day I'll get around to completing it.....

That connector is actually +12V, A22 and /WR on the SCSI/SCC I had always wondered with that connector was for, I guess a ISP rom makes sense! On annother side note, U25 appears to be a footprint for a 27C512 type eprom, I have always wondered what that was there for but I haven't ever seen a...

Pins are 12.7mm in length (Which is the lengh of the pin above the plastic part) specifically they are these ones https://uk.rs-online.com/web/p/pcb-headers/2518351 Could have been form my bench too there's far more random SMD components floating around n there than there really should be so it...

Next batch of Rocket SCSI Booster PCB's are here! The should be assembled and ready in a few weeks, if your interested please keep a eye on the FS thread :)

You have far more dedication than me, I would have said "screw it" and asked Bolle for a new PCB about half a hour in! That gives me PTSD from my ThunderCache experiments. I still can't get my original card working with all the original parts let alone my clones..... Both are now one the...

Good spot! Positive on C10 should be connected to pin 6 on UB10 (along with R83 and C103) but not R82. I had it connected to the wrong side of R83/C103 (which connects to pin 5 and R82). Have corrected this :) I will also say that the apple schematics are now floating around which should...

I have the parts to assemble 3 or 4 more, just haven't had the time recently to actually assemble them Will update here and on the for sale thread when they are ready. (A couple of people have already PM'd me over the last few months so they'll have first dibs when they are ready)

The PCB's are £45 and shipping to the US for a single boar is £16.75 The boards come with all the birdseed on the bottom side populated (bar the two transient suppression diodes under the ADB ports) so you just need to move the topside components over

Indeed it is, just two signal layers on the outside and then power / ground on the inner two
