Excellent! What's your next move... SRAM access, clockspeed, ...?

Probably the FPU.

Great work, you've earned that glass of wine.

What's that memory tester you're running there?

DiagROM by Chucky

http://www.diagrom.com/

Its a ROM replacement with some personal hacks/mods.

Oh yes, I have that burned but have only used it on Amigas too broken to render a screen.

Speaking of DiagROM... I have an A1200 motherboard that I got with buggered traces around the CIAs. I have them removed so that I can bodge wire the missing pads to where they need to go. Will the DiagROM work without the CIAs installed at all? Seems I read at least one needed to be present.

Little (further) off the thread topic... but yes. If the CPU runs you will see something on the rs232. I have been working with Chucky on his ROM but we use different tool chains so there are challenges in working together.

Lets finish 2016 with some Homebrew p0rn

Quick benchmark numbers @16Mhz (off the siggen) and being dumb and letting the Amiga generate DTACK. (No Burst or STERM yet)

I cant get the FPU to work yet though. Yellow screen on kickstart 2.04 (tried several FPUs and resoldered the socket).

I've just respun a revision 2 of this with an Option for 4Mb of static ram.

Hi...i am a new user here.In my case i am not putting a SMPSU on there this time. Just like the 020 board this will not have any RAM so the performance gains will not be worth anyone getting one. It is intended as a stepping stone to a full 060 board.Probably for the cd32 though as i've ordered up some 182 pin edge boards.

circuit assembly

Hi the open source TF520 does what you are attempting already and I opened it up to stop people reinventing the wheel...

https://github.com/terriblefire/tf520

As you say there is no need for SMPSU until you hit the 060. I'm working towards that but the CD32 guys don't want beyond 030 because it's not compatible. The community is also talking about standardisation on a pci style connector for CD32 and A1200

plasmab · 21 May 2017, 09:50

For anyone not following my YouTube channel/thread here the TF530 is now up to 50mhz and getting 10 mips as reported by sysinfo.

And it's open source.

Sata in the next revision
