Cloning the Interware Booster 30

[max1zzz]

Will JLPC(?) boards with more than just the teensies pre-installed be possible?

Unfortunately not, all parts for JLC assembly have to come form LCSC who aren't going to have stock of the 68030 of GAL

Are you switching to socketed CPU, sounds like it.

There will be a revision with a PGA CPU, currently my design is using the QFP part the same as the original board

When you do your layout, maybe run all the 030 signals to a PDS passthru? Got notions about implementing that one.

Already been thinking about this It's on this list of things that may be done in future revisions

The board has been sent to JLC

@max1zzz any progress to report, ETA for ProtoBoards?

You have so many projects going it would be great if you could do a Max's Bench thread listing links to any that are publicly posted. I'll bet I'm not the only one who can't keep track of your work. You never know where someone might come up with an idea or suggestion for one of them or add more ideas for projects to overflow of your workspace.

@Trash80toHP_Mini Boards are on their way, ETA is currently Monday

My publicly posted projects are currently posted on GitHub: https://github.com/max234252/ The main issue I have with posting them there (or anywhere) is getting the "paperwork" (BOM etc) for the release done.... I still need ot do the BOM for the LC II board so I can get that uploaded too

I meant a thread here in hacks to point to such repositories for such projects and the threads that bred them. Kinda like may ancient jt's hacks thread.

They are here at last!

And a assembled and slightly fluxy example:

And the good news is it works! Well it mostly works... If you don't install the FPU it works out of the box but installing the FPU was causing a System Error on boot. turns out I made a couple of mistakes with the FPU connections, firstly I connected A0 to GND not VCC and secondly pin 43 was left floating rather than being connected to VCC, correcting both these got the board working with the FPU

These are a bit annoying but should all be able to be patched under the FPU socket so it's not the end of the world

So now... it's time for FASTER, FASTER!!...

Well done so far!!
