Aaaah, those boards are made by @DosFox on here :)

That is a spectacular writeup, Steve - loads of detail - glad to be of at least minimal assistance on this!

There really is something about the MSX Line of computers that just makes them look peak 80's! There must be some commonality in the design languages used back then!

That fact that you have alternating stripes would indicate that it's a RAM issue. The ADB isn't needed to get to a grey screen, AFAIK - GLU, for this early in the process, will simply be inverting the clock signal - it's a schmitt trigger inverter gate. Also the clock isn't an issue as you're...

I thought the Xilinx XC9536XL were out of stock, too?

This is amazing! Excellent work, sticking the thread!

Paging @mmu_man ...!

I wonder if it's possible to find a good high resolution image of the board, read the part number off it?

Also, a reminder that not everything needs to be mac or even computer related - as evidenced by some posting older audio equipment! Only 3 weeks to go til the entry window closes, folks!

Love that board shot!

A few of us once talked of such a thing... Perhaps @Zane Kaminski might jump on board with a fresh design - I know a 1mb L2 would sell like hot cakes

Mouser also sell 4-pin mini din sockets that fit perfectly.

Thanks to @RetroTheory , the case has arrived! I've not unpacked it yet, i've had 0 time to deal with any projects lately, I'll need to recap the Motherboard before I go ahead with the build, just to make sure the board I want to put in there actually works! 😅

Have you got any super hi res images of the card we can use to spot anything visually wrong?

So...how close are these to release? ;)

You do need a minimum of 1MB (in Bank A) for anything to really happen, as the built in video needs something to use.

Y4 should be a simple 2 pin 32.768KHz crystal (not an oscillator), if you're not getting anything from that at all when power is applied, that means the RTC won't be running, and won't be generating the 1second pulse output, or sending any data to the VIA. Although that may not have too much of...

I have to say, that is insanely clever!

Ah sorry you wont have the MDU or RBV, i was thinking of the IIci there - the E clock is the fixed 783KHz clock used for peripheral timing. It's the bus clock speed divided by 10, typically. So it may be 1.56672MHz.

Yes, you qualify! Entry isn't excluding any member at all!
