Can anyone help?
My system is a SD SBC200 with Versafloppy2 floppy disk controller. It also has a Vector Graphic flashwriterII board for video output, and a Expandoram 2 card. With a Vector Graphic monitor ROM installed I can run this machine via the flashwriterII card with output to a composite monitor, or with the SD monitor ROM installed I can run the machine via serial to a terminal. Both setups access a single Gotek flashfloppy drive. The same Gotek disk images run CP/M 22 on both setups.
What I have been trying to to do is set up a 3.5" drive as Drive B. I have a Teac 235HF that has been modified to spin at 360rpm.
CP/M can see the drive as Drive B, and I am able to run a format utility and the drive seems to format and steps through it's tracks...unfortunately I can not access the drive after the format and I get a BDOS error.
I should mention that this setup is very similar to my IMSAI 8080. A Gotek + modified Teac 235HF 3.5” drive, although the Teac drive is setup as drive A. The IMSAI uses a Versafloppy1 as opposed to the Versafloppy II in the SBC200. The IMSAI setup works fine.
As a side note, the IMSAI can also boot the exact same Gotek disk Images as the SBC200. In fact I just maintain one library if disk images for both systems.
Anyway, was wondering if anyone had any insights into my issue?
