I'm so used to only having 64KB of RAM I didn't notice

Yay !

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



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...

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

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...
