holy crap well done.

I haven't forgotten I need to send you the scsi daughterboard, just been a manic few weeks. Sorry!

Well done! I'll be needing one of these

@cheesestraws No problem, I wasn't in a rush as I hostly wasn't expecting them to just work!

A small number should be available in a month or so once the last of the parts have made their way to me, I'll do a larger batch once I have had a chance to make some revisions tot he board design to make them a bit easier to assemble

Damn! Really nice job. Does it need old PALs or can it work with modern ATFs ?

Needs older GALs as it is mostly 20V8's with a few 26CV12's and a few 22V10's, the 22V10's being the only ones currently in production (In some cases 20V8's can be converted to 22V10's but not always)

That was quick! Well done

Is this a 25MHz Rocket only or can you upgrade to 33MHz? In any case, this is fascinating news and I can't wait to buy one from you! I'm especially also looking forward to the SCSI daughterboard.

It's the 25mhz version, I will be experimenting with overclocking it to 33mhz (or faster!) once my replacement oscillators arrive

The important question is... What are you going to call it?

That's a good question! I have no idea, if anyone has a good suggestion let me know

Rocket Max ?

How well is chip supply for these btw? Are there any ICs which you can only get NOS or reclaimed? (apart from the 040 of course). I‘m having trouble with the QuadraLink and its 74ALS651 and 26LS30…

Mainly the SIMM slots..... I can't get them locally for a sensible price. Converting to 72pin simms seemed like the way to go initially but actually proved not to be workable. I ended up making a design that uses custom RAM boards which I'm sure will annoy some people but I couldn't think of a better solution

Is the photo above already with your custom RAM board design or are these still standard 30 pin SIMMs?

Honestly optimising for 'what connectors one can get' sounds highly sensible to me. It doesn't take many projects involving multiple boards and connectors between them to get a sympathy for modern Apple's desire to have as few connectors as possible.
