Matchbox sized 6502 / Z80 / 6809 Co Pro

[BigEd]

Indeed they are, as built. But every expansion added is another element which might push something out of spec. Even then, a lot of things just work. But in both Matchbox and Pi we have seen that we have to be careful, and that individual machines differ, even before you add the various popular expansions.

is a R6502AP CPU http://www.cpu-world.com/CPUs/650x/Rock ... 502AP.html compatible
with a SY6502A http://www.cpu-world.com/CPUs/650x/Syne ... 6502A.html they are both 2 Mhz ?
They look the same to me

Yup! Should be!

Just for interest to others that may have the same problem viewtopic.php?f=44&t=8852&start=1140#p183626 with the LX9CoPro, today I got another UM6502A processor chip put it in and no problems with the CoPro works perfect (Elite ran flawlessly) with a new chip in so I guess my old CPU is a bit dodge, as the CoPro did work with a 65C02 in in BBC but wanted the correct CPU in there as a lot of software that use no-standard op codes will not run on a 65C02.

I am updating a CoPro! I am preparing one of my Copro's to pass on to another forum user so it was time to update my unit. Well I have not done that in a while. Oh boy it took a while to assemble all the physical bits but then I had to do the update.

Well it was hard to find the information so for my benefit next time I made this:
https://github.com/hoglet67/CoPro6502/w ... -the-CoPro

I hope hoglet does not mind me messing with his words of wisdom.

From this you can see I am no technical author, feel free to suggest updates or even have a go at updating the page. I have a couple of photos I will add later.

On a plus point I have a working Acorn machine turned on for the first time in ages

I've no problem at all with people improving the documentation. Thanks.

Looking at github, there have been a few commits since the last release in September 2017:
https://github.com/hoglet67/CoPro6502/c ... 9...master

The first four (Aug/Sept 2018) are just me messing around testing a cycle-accurate 65C02 core. None of this is active code.

The other four (Jan/Feb 2019) fix a bug in two-byte mode. This is needed if you are using a Co Pro to run an Acorn Level 3 File Server. Most people aren't, so I wouldn't worry.

Is this board destined for Andy (anightin)? He has a Xilinx Programmer so will be able to update himself in the future.

Yes it is. I can hold of sending it and update it again if he needs the very latest.

I am hoping to become a bit more active in the Acorn scene again in the next few months. I only have one machine working at the moment so need to find some time to repair all that I have.

No need to do that, as I'm not planning a new release (I'm busy with other things for the next two weeks).

Will there be anybody coming to ABUG South with the equipment to update the Matchbox so I can get mine updated? I think my last update was last year with the PDP11 IRQ fix.

I'll have the Xilinx programmer with me.

If I remember correctly, those PDP11 changes were to PiTubeDirect, not Matchbox.

Ah yes, here they are:
- PDP-11 Co Pro - reset clears PSW
- PDP-11 Co Pro - updated client rom to 0.28
(this is why I love git...)

So we have:

PDP11:
- PiTubeDirect - v0.28 (updated 19/1/2019)
- Matchbox - v0.27a (updated 5/10/2017)

6809:
- PiTubeDirect - v1.05 (updated 5/10/2017)
- Matchbox - v1.05 (updated 2/10/2017)

But looking at the version log in the 6809 client code, both will be missing the 12-Jul-2019 update

Code: Select all

; v1.05 25-Aug-2017 JGH: OSFILE/OSGBPB/OSARGS use big-endian control blocks
;	02-Sep-2017 JGH: PRTEXT preserves X as with Z80 Client.
;	12-Jul-2019 JGH: KBDTST/KBDIN routines use pending input from OSRDCH

This must be one of the best forums around! I Don't even have to write my own questions or answers for some topics

Much appreciated both

The ATOM is eagerly awaiting the Co-Pro

Update: Received today with thanks

[anightin]

Now working nicely:

[trixster]

Superb!

[KenLowe]

Nice setup! That's exactly where I want to get to. It's probably going to bankrupt me, though

It's come a long way thanks to Hoglet, Roland and others in this great community. This photo was the Atom in June which came in a non-working state with most of it's IC's removed. This photo was after it had a bath, and after I fitted a new power connector and removed the regulators. I think the first thing I added was a AtomMMC thanks to Sir Morris then a Noisekiller from Hoglet, then a RAM/ROM board from Roland -- saved me having to source the ROMs and memory chips.
