Interesting things that arrive by post

The other week you may remember @Steve managed to acquire some Transputer items from eBay. In amongst that lot were a number of other ISA boards.

There's a number of the top ones and one of the bottom ones.

Doing a bit of googling it looks like these are boards used for carrying out ultrasonic rail inspections or weld and material inspections.

There's lots of interesting stuff on these boards, xilinx chips, DSPs etc.

So the question is, what would you do with these boards?

This is a close-up of the DSP. I wonder if @dml or @agranlund think this DSP could be used for anything interesting on the Raven?

I think thats the DSP used in the Apple Quadra 660/840AV machines (or a variant of) and various DSP cards for the Apple machines too.

EDIT: There was also an Amiga A3000+ (prototype?) that had a similar AT&T 3210 DSP.

Theres even some code knocking around, if anyone fancies knocking up an Atari board and porting over:

Interesting.

BTW I also have a bunch of Transputer related stuff, some from wheeebay and some I just had stuffed away in boxes for years. Nothing as weird as those cards though.

Not familiar with that DSP but I do have a box of PGA XSP56001s here, was wondering if it would make a good Falcon'ish card for the Raven...

I think I'll harvest those boards for parts and as suggested, maybe see about making an Atari related board for the DSP and see what we can do with it.

This Motorola document even has schematic and PAL 22V10 equation for making a simple DSP56001 ISA card :)

That's cool, will have a look at that when I get a mo

Ok I thought I had more of these, but apparently two:

These would be a bit more code-compatible with Falcon/Atari stuff, assuming such code is reworked to use different port registers etc - although probably that at a bare minimum.
