Is this what I think it is?
« on: December 25, 2016, 01:12:41 AM »
I make it an original issue  Commodore Bridgeboard, 286 PC on a card for Zorro 2 or Zorro 3 Amigas.

Probably too big a job for me to handle, but I pass is on in the hope it will go to a good home, or somebody who actually needs to test on ancient IBM PC compatible hardware. (Don't scoff, a LOT of defence contract and financial services work has to pass that hurdle).

A2000 is a great choice for that card. It likes roomy Amigas, because you nearly always end up fitting extra PC cards too (dirt cheap, the Bridgeboard is the expensive part). Get the permission off the retiring head teacher in writing, should make that A2000 yours in a very legally enforceable way, when you print out the authorization and show it to whoever has the cupboard key.

Looks in excellent condition, and still has the socket for the 286 FPU - again, dirt cheap, fairly available.

The long ribbon cable is a floppy connector for a PC floppy, I remember that much.

May it bring you much luck. :)

As the 286 is soldered in, it will be very difficult to overclock or replace, and if it is an early version of the chip (very unlikely) it might not like DR-DOS. Only snags I can see with it.

CBM did not ship that many of these cards. They produced a 386 version, and I think Vortex did a 486 based version, very briefly.

Vortex's board (http://amiga.resource.cx/exp/goldengate)  is distinctly different from the Commodore Bridgeboards. Different PCB,  different software. It's "based on" the 2386 only in that it's also a  386 (or 486). Unless you're thinking of a different Vortex board.

This is the 486 version of the 2386: http://www.bigbookofamigahardware.com/bboah/product.aspx?id=331

I always wondered about that, at the time. I could not understand why a true 486  would need an empty socket for an FPU... did not make sense to me at the  time, unless it wasn't for an FPU but a different upgrade
.
Seem to recall an embargo on international calls at the time from Future, so just phoning up Vortex and asking wasn't  really an option. Email was similarly very problematic at the time. And  my German is very simplistic, not very good for technical questions and  answers anyway.

Thank you. :)

All things considered, ~$130 isn't terribly much  for a nice piece of Amiga history. I don't expect much from it, there's  always virtualbox/dosbox for anything requiring a sane level of  performance

WRONG. There is a helluva lot of old CNC and CAM kit that demands a hardware PC to control it, and a software only emulated system just will not do the same job. Having 2 sets of hardware in the same box is definitely recommended for development and test systems.

Fancy going into business refurbishing old GERBL hardware? Or come to that, ANY old hardware that needs a 90s PC? I'm talking industrial robotic kit, mills, lathes, that kind of thing.

Specialist job, but it can pay very, very well. ;)
