A lack of smoke is always a good result

Indeed it is !

Long time no updates on my Tandy, so here we go.

First, I have upgraded the serial port to a fully fledged one.

Sorry, I didn't take any pictures during the process, but for those who are interested, here's a link to a forum explaining how to do it:

https://forum.vcfed.org/index.php?threa ... 240/page-2

(Just scroll down a bit).

Using an OPL3LPT in stereo and ZIP drives will be a piece of cake now.

And second, I'm planning to add an 8088 FPU to this machine, so I'm just experimenting for now.

Here are some pictures:

Since I can't fit the add-on board directly on the motherboard, I had to build a flat cable relocator.

So far so good, but I'm still waiting for the FPU to be delivered.

I found this project (originally for a EURO-PC) here:

Still have some PCBs left...

That's all for today.

The Tandy is looking great, nice to hear some updates from you, it's been a while

Yeah, I've been quite busy these last few months and I don't have much time for my hobbies.

Ok, some fresh news after a busy day.

Since I wasn't able to read my disks, I had to RF shield my flat cable.

Everything is back to normal now.

And just some minutes ago, the FPU arrived !

There was no smoke when the Tandy was powered with the FPU in the expansion board, so I can sleep peacefully tonight.

I have now to test whether the FPU is recognised with Microsoft Diagnostics.

More to come later.

Exactly the same here.

Its always great news when things start moving again.

Well done!

Thanks, but the journey is not over.

I still have to cram all this stuff in (not to mention the RAM board already installed):
