I recently picked up a 3000 in excellent condition and have designed and built a mod that allows the 3000 to run under Mach3 control. It uses a simple switch...
I found my bug. I was labouring under the delusion that a Z80 bit test reset the carry flag. It doesn't. If everyone is going for Andrew's Mach 3 pull the PIO...
Robin, I think I speak for everyone here. Keep working on your solution. We all like options. And not every option is good for everyone. I have been following...
+1 to Sean's comments. While I love the notion of using Mach, my preference is to have multiple options. Some may be easy, others (like the collet upgrades)...
I also agree that we need options. I want to look at the mach conversion but, I know there will be something I do not like. With the Z80 eprom port, there...
Just realised, I haven't shown that it cuts. I can't do metal because it would go everywhere and el wifo would terminate me, but I can send it through the...
... Hi Roger Go on, see if it all comes back to you. I wrote this for ZASM but MASM might have been the better choice. http://www.robinhewitt.net/bios.s This...
Me again I've had a big think on how to do this EPROM thing. You cannot write a program before you know what the program does, but I now have a plan so I can...
I wrote that program for the Roland end of the cable and it was horrible. Much too complicated. I never knew where I was. So I had another think and now P1,...
New EPROM and software seem to be working. I'm using a dual core 2.8 GHz PC and Windows 7 home edition. I can shrink the program down and do other stuff while...
You are not the only one Roger. Greate work Robin. By the way, I have been cutting aluminium on my 3000 for more than 10 years without any problems. Harald...
... Hi Roger That's very nice of you to say, but it is only typing. Do you have that pioneering spirit? Can you program a 32k x 8 EPROM? If not I can send you...
I probably can. It would be good to dust off the old PNC and see what it can do. I have a programmer around somewhere. I might even have a 32kx8 EPROM. ...
... Hi JW This is just a test to see if all Rolands are the same, one glaring omission that leaps to mind is that it doesn't turn the motor on :o) OTOH it...
Robin,  send me an eeprom and I will install it and test for you. I need to update my programmer. I guess I should do it. Do you have a suggestion for...
Robin,  I do embedded code for a multitude of processors. I just got away from the eeprom thing and use flash.  I ran across my eeprom emulator last week...
... Hi Roger This is pre-flash, pre-EEPROM. this is EPROM. You have to shine UV in through the little quartz window to erase it. Send me a mailing address and...
I have the interface board working and have built up four of the boards. The design is uploaded in the files section of this group. The cost of materials for...
Fantastic Andrew, Great work. Looking forward to seeing it in action with the YouTube video. You mentioned you had made 4; would you be willing to sell one to...
Dan, Yes, the three extra are for sale to the group. Roger has requested one already so I will allocate the second for you. I am selling them at my cost,...
