Yay !

I have now 2 weeks off and beside some travel, I plan to finish some retro stuff.

:D

I made some progress on the Tandy today morning. First, the missing rubber feet are now in place:


The NEC V20 is also fitted:


I also plan to fit an RTC from Cybernetic Systems under the BIOS chip, but for the moment it is unfortunately out of stock...

Here is a view of the motherboard:


The V20 works fine:


And the 3.5" FDD replacing the 5.25" one:


I am still waiting for my VGA card bought on Tindie. I already have the "plus connector" to ISA adapters so I could fit it, together with an XT CF IDE Mini I have to build since they are not available any more...

More to come later.

Looking good. I presume that the V20 is a simple drop in upgrade that gives a slight performance boost?

Yes, you presume correctly.

And according to a test made by Adrian's Digital Basement, the average boost increase is around 24%.

I've probably watched that episode :)

A 24% gain is well worth it for a simple chip swap.

You've also reminded me that I need to finish my XT-IDE card. It's built but I need to flash the ROM.

For sure !

I have all the parts for the XT-IDE card bar the reverse CF socket, not delivered yet.

In what kind of machine do you plan to use yours ?

Well, TBH I don't have a suitable XT machine at the moment and my Book 8086 has it built in, so I will probably test it in my Amstrad Alt-386.

I was actually given the PCB so I just thought 'I'll build this' without any real thought about where I'd use it :dizzy:

You're a bad influence 🤣

I've been looking for one of these now 😁

Surprised how expensive they are.

Sorry, I don't do that on purpose...
