Re: Cheap Xilinx LX9 Starter Board

My reply from Adam was:
New message from: eepizza (1,008Red Star)
Hi, Andy. Glad to hear from you. As I remembered, your parcel was returned to us recently. And then my colleague redelivered it with the better service. I will give you the tracking number this week.--Adam

I expect it's just really slow post (esp. at this time of year).
Yup, I'm hoping that's the case. Thanks again. I'll update the thread when the boards arrives.

Re: Cheap Xilinx LX9 Starter Board

Did you ever receive the order update that indicates it was dispatched?
Thanks Dave, Yup, it was marked as dispatched on 6th Nov with an estimated delivery Mon, 11 Nov 2019 - Thu, 5 Dec 2019

I've messaged him today so waiting for a reply.

Yup I’ve seen thar advert — building this board was tedious in places but on balance very therapeutic. I really enjoyed sour...

Re: Done scratching that itch

What a beautiful soldermask. I did a rebuild on my Norton Commando 750 in the 90's with a mate, I had the frame powder coated and all the casings polished -- we just sat there with a beer some evenings admiring the part built machine as one would a piece of art. This truly was one of those moments,...

Done scratching that itch

I was busy building my System 3 keyboard, and generally minding my own business when I spotted Rob Taylor's A500++ board on an epoisode of RMC.

#-o

Lots of pocket money and a few weeks later the itch is now scratched:

Re: Looking for System 1 software

I'll try and have a look this weekend and let you know -- I haven't tested the tape input circuit on my System 1 build yet!

Edit: I now have your as1build script running on the pi so that's step 1. Wav file sounds as I expect it would at least :)

I've been messing around with generating WAVs from assembler output using minimodem.

Please could someone try loading this (rather minimal) test program? It just p...
