Yep it's a homebrew
2Mb 32bit RAM,
1Mb 16bit FLASH
3 x Serial ports
SD card interface
UART2 dedicated to propellor vga terminal board, although I'm still using UART0
as a dumb terminal connection.
Not played with it for a couple of months as life/work/broken chainsaws etc.
gets in the way this time of year.
pics follow hopefully?

P.S. Have found an 68060 monitor listing, but .LST only
I know I have the .ASM files on a sytem in the shed, but the shed roof is leaking,
Had to move a few systems, and I can't fix the roof until it stops raining, It's like
the monsoon at the moment.

Looks good to me!

Sorry about the front panel pic,
I must have been shaking.
Not enough beer, and its my birthday, going to sort that out
RIGHT NOW!

That runs at 200 MHz?? And I can't even get a breadboard to behave reliably at 20 MHz.




Hey, no rush. I'm nowhere near ready to do software yet lol

And happy birthday!

RE getting your 68000 going,
what are you using as breadboard? Not Veroboard I hope
you'll be lucky to get it to run @ 4Mhz.
Use a 3U square pad or round pad board, socket the chips ( round pin )
get some .030 kynar wire wrapping wire, and a hand wire wrap tool
just for the stripper. ( They were not cheap, the last one I bought approx 25 years ago was £27 )
Only solder a few pins on the sockets just to hold them in place, then feed your stripped wire
through the hole next to the pin you want to connect, wind the stripped end round the socket pin
and solder. You can get up to 3 wires down one hole, but it pays to think how many connections
go to that pin.Use miniture snipe nose pliers to wrap it round the pin not more than 1 turn
and cut the excess off with mini snips.
I've found it helps to hold the wire down with a flat blade miniture screwdriver so it stays in place
while you wrap the wire.
Note that all the wire wrap ( insulated ) is on the component side, I've seen single sided boards done
with wrap on the solder side, and it's a nightmare.
As per 68060 certain pins need to be tied high on the 68000
offhand these are -BG -BR -BGACK
and the interrupt lines -ILP0 -ILP1 -ILP2
plus -DTACK which is open collector
Will look up free run connections for 68000
As I remember did it about 30 years ago with +5v,GND, a clock 8Mhz, various pull ups
D0 through D15 pulled low, this makes instruction = $0000 = ORI.B D0,D0 which is
effectively a NOP.
-HALT and -RESET pulled up by your reset cct. until you press reset
then get your logic probe or hard wired LED on the address lines and watch them toggle.

I will post the free run 68000 connections A.S.A.P.
we've got to get you running some hardware.

Nope, I'm just using a cheap old breadboard like this one.




Thanks for that... but I already got a freerun operational! The breadboard prototype runs reliably up to around 6 or 8 MHz, but the tester I pictured above should allow up to 16 MHz.

Today I got the Freerun Tester back from the assembler and fired it up. I'm happy to say it successfully tested out all the 68Ks I have lying around in both DIP and (with the adapter accessory) SDIP format.

I see what you meant, Ian - I got even my old 68000P6 to freerun at 16 MHz flawlessly! Granted, this won't give the data bus the "variety" that running actual code would, but... it's still nice to see!
I also noticed no difference in heat output between under- and over-clocking the chips.

On a somewhat unrelated note, I got this ATX Adapter made as well. Now I can power my breadboard projects more effectively than wiring them up directly each time as I used to.

I have to give a big shout-out not only to Dave, my board layout/schematic tweaking/soldering guy, but to all of you here as well. You all taught me a lot; enough to make my first venture into making a piece of real hardware a success, and I sincerely thank you.

A good result!

That's great,
It depends on your memory access time as to how fast you can run them.
As I said before you usually overclock 68K by 25% without any probs. both
with heat and memory access.
060 different ball game, power hungry HOT HOT HOT
big heatsink with a fan if you're going to overclock it.
Shed roof fixed so various systems back in place, it was the ultimate
in water cooling.
Car gone tits up, so have to go down to Glasgow for another one,
so will post .ASM files later this week

Yeah, that's pretty great. One more reason to love the 68K over Intel!



LOL!



Good luck! Looking forward to that monitor

HI all,
Looking at Ebay, there seems to be a few fake 060's from china
not as many as a couple of years ago.
There's ones marked as MC68060RC50 with the I think the Freescale era > in dots
if you know what I mean, and the top right of of the chip where you have the
mask # and date code are obviously painted out. BUYER BEWARE!!
almost certainly not working at all.
Got a new ( different ) car in Glasgow on Thusday, what a nightmare
1 train, 2 coaches, left home 0630 picked up car at 8pm with the prospect of
a 4 hour drive home. So after 18 hours travelling finally get home.
Found 060.ASM files, managed to put them on a duff memory stick, arrgh!!
will put them on a good one and transfer them to my linux laptop to put
them online.

Best Regards to all
Ian Hughes ( carronjack )

I know, I've seen several that make me wonder!


Yeah. AFAIK, the '060 was way out of production by the time the Freescale name was in use.


Nice. At least you got a new ride!


Good deal. Will it run unmodified on the '000 as well?

Hi all,
Fired up one of shed systems Sunday to get the files
power supply dead, these days nothing built to last.
but here's 060 bug listing to be going on with.
Yes it will run unmodified! on the 68000 with a comment out of the
PROC 68040 and
DC.W for the CACR regs
Any 68000 code will run on the 060 assuming it runs on the 68K.
Have a power supply in a spare scrap machine so will lobotmise that
or swap out the HDD.

Best Regards
Ian Hughes ( carronjack )

Cool, thank you!


Sweet! What assembler did it use?


Good luck!

Hi,
assembler used was The Macroassembler AS
either google that
or go to
john.ccac.rwth-aachen.de:8000/as/
