Success !

Awesome work Bill.

Does the ROM socket allow Ram to be fitted there for 48K or can you use say 8K on board plus the 40K ?
Please, one if each for starters.

Rich I have 5" images of your DOS/65. I have tried booting in winOSI emulator and get the A> prompt but with a PEM -Bad Sector error after responding to the number of drives prompt. Warm boot with CTRL-C - hangs accessing tk 0/1 Go $xxxx -hangs accessing tk 4/5 ? ( Was hoping to call some code loade...

Welcome Rich.

I have created a DOS/65 topic under the Files (software, ...) section for further discussions

RAWDUMP program simply dumps the raw contents of each disk track (including formatting bytes) to a file. The format is: images of 5.25" disks are 92,160 bytes long (40*9*256), with the raw image of each track beginning on a 2304-byte (9*256) boundary. Images of 8" disks are 295,680 bytes long (77*1...

I have had it confirmed this is still a problem at 2Mhz with 8" disks.
Anyone tried Jeff's fix?

I am working on a two part project. The first part is a small program that runs on a Challenger that takes commands and data from a host (Mac, PC, Etc) that will send it disk track and sector data for the purposes of re-constructing floppy disks. I haven't tested it yet. I am working on the host pr...

I think "stock" OSI 8" systems ran at 2MHz ??

Whats your CLK speed Grant, does it work at 2MHz without dropping bytes ?
