Yes definitely. Well spotted. Hope I remember when I get to plug one in ! Kind of weird having B1 on the right hand side of the bus and boards is confusing enuff.

For some time I've wanted a 505 board but lately I think the 502 has such great potential for upgrading and in conjunction with a 470K and 582 etc would make a better system by providing both BASIC in ROM and OS65D capability. There have been many great mods by users in the past detailed in Aardvark...

Dave do you think you could make something similar to the 582 4 slot from your 580 gerbers ??

Welcome Barry, I believe there are a few members with working C3's and others a bit wary to turn them on after all these years. The winOSI emulator on Marks site now supports 65U and there are images in his software section. http://osi.marks-lab.com/ Great info at OSIWeb.org

Welcome Gary. Do you still have the 400 system? Must have been fascinating to be involved with those companies back then. By the way, did Chromemco ever do any software for OSI systems ??. Dave sent me a CDOS Users Manual 1977. I have a CDOS/CP-M type patch for OSI 65D that Ive always attributed to ...

Can we have an update on the pre order situation please ??

I am going to finish off my quick loader for this and post that soon. Last night I added some features to QuickLoader. Now, in the .QLD (quickloader files) header, you can specify, the start page, number of pages, and start address to run the loaded file. Also, quickloader now gracefully terminates...

Not here unfortunately. It would be nice to know the release dates of the different versions also. I note version 3.0 and presumably earlier versions had the "OSI-65Dv3.0" string around the adaptive seek rate patch area $2297-. I looked at the early version of WP6502 but the code is entirely differe...

I was certainly hoping Bill's board will be the 2716 type. Thanks glitch useful indeed. "The fact that this CPU board has this extra RAM (128 bytes, normally located at F2xx) indicates it was the "deluxe" version of the 510 board with software-selectable processor (allowing a program to change proce...

I have some files I will post soon. Meantime any chance you could up that C4 to 32K to cope with bigger splits ??
