Sure, i'll attach them here :)

That lookup table is just what i was searching for! :)

Usually Apple HD SC Setup would do the initialise of your drive, loaded from the utility disk. However, if your drive is dead - 2.5" SCSI drives in working order are hard to find might it be time for one of these: https://androda.work/product/powerbook-bluescsi-version-4-f1-tba-pb-v4/ perhaps? :)

Hi Jeff - it might be that this can fix your issues: https://tinkerdifferent.com/resources/zero-track-alignment.37/

The good thing about the SE/30 Reloaded from @Bolle is that the Pick & Place and BOM are available on GitHub for you to be able to have JLCPCB pre-populate the rear of the board with the fiddly parts, leaving you to do the rest on the top, which are considerably larger.

Yikes - the RTC chip looks like it's been eaten away :( It may be a good candidate for an SE/30 Reloaded build - i have a spare RTC chip i could send you, if you wanted to go down that route, but i definitely think it's the best course of action.

Not at all! Don't worry, it will be released on github as the gerbers and the sprint layout this year - just gonna recoup some costs first :)

Unfortunately, i don't have a board view, as such, it was created with Sprint Layout and currently it's not been released as Open Source (yet - it is planned this year, though).

Both boards are back in stock at MacEffects :)

ASG = Analogue Sound Generator TSM = Timing State Machine TSG = Timing Signal Generator BMU = Bus Management Unit LAG = Linear Address Generator

Hmm, interesting - none of the yahoo japan pages load, i get an error message saying that it's unavailable in the EEA & UK :/

Never had a bad experience with my Yihua 959D - but the Atten would be my choice now, if i had to start from scratch.

Gotta say, i really love the RT-65B - i made a bench supply for testing SE & SE30 logic boards, using one of those. Still keep meaning to get another one to shove into the original Amiga power brick.

@techknight dug this up in the discord:

BTW just to clarify - this is the one i purchased: https://www.donberg.co.uk/descript/h/hr_42086.htm

Did a bit more measuring: between pins: 1 + 4 = 1.5 ohm 1 + 5 = 1.5 ohm 2 + 3 = short 2 + 7 = short 2 + 8 = short 3 + 7 = short 3 + 8 = short 4 + 5 = short

Out of circuit....nothing at all!

1 to 3 = 1.5Meg 2 to 4 = 1.5Meg 5 to 7 = 1.5Meg 5 to 8 = 1.5Meg All measured in circuit :/

That $99 one is the one i bought, as it's the replacement that is put in, in place of the earlier type 26C model.
