I sent a PM to Rich Leary a few days ago, asking if he might post binary images of bootable disks. He replied that he could, and expected to post disk images (for the C1P) this Sunday.

The link I posted is to a Canada-specific site, for some reason. For the U.S., change the .ca to .com. For other countries, click on the flag icon at the upper right and select your country.

I saw this link posted somewhere as being the connectors to use to connect boards to the OSI bus. I thought it was somewhere on this forum, but apparently it wasn't.

Since Dave seems to recommend doing so, I am posting the needed ROM files after all. I had forgotten that only ZIP files can be posted as attachments here.

It seems that paste from the clipboard is in fact included, and actually is too easily triggered. It happens when I am not trying to paste anything, just clicking in the emulator window to reselect it. I'd suggest putting this function in a menu, not triggering it by clicking in the window. (And if ...

No, the attachments didn't seem to take. Anyway, files of the needed code can be generated from the latest version of WinOSI by selecting C3-OEM mode and using the "Save Code" option in the File menu to save $FE00-$FEFF and $FF00-$FFFF.

Can EPROMS really lose their programming over the years, even with the window covered? Anyway, only two are needed for serial use, the 65A monitor program ($FExx), and the 65F3 reset code/floppy bootstrap ($FFxx), which is the same for serial and video systems (it reads the $FExx ROM to determine wh...

If you have a 440 (and a backplane), and the board is running, you should see the H/D/M? appear on the 440's video output. You wouldn't be able to respond, though, since the board would (almost certainly) be looking for a polled keyboard, which only works with the 540. Maybe Klyball could burn a 65A...

After being away from this board (and not in good health) for several months, I finally logged back in and saw this new version of WinOSI. Quite an impressive set of changes. The most welcome is the ability to run 65U. The cut-and-paste from screen to clipboard is also much appreciated. The opposite...

Hi people. From the photo that was posted of this board, it seems to be configured for use with 540 video and polled keyboard. To use it with a serial terminal, the 65V PROM (the middle one, which is mapped to $FExx) would have to be replaced with a 65A PROM. The 65A code is available in one of the ...
