An enthusiast build – and i couldn’t even be sure that it’s complete.
Andrew, a friend from the ARC Group, has supplied me with a lot of funky gear including a box of S-100 cards, a couple of chassis, several 8″ floppy disk drives, and about 500 8″ floppy disks.
One of the challenges is that the relationships between all this kit was not obvious. This one i was only able to sort out because i found the source for some boot ROMs on one of the floppy disks. Even now i’m not sure if i have the original RAM card but the one i’m using does just fine.
It uses the following cards:
- Compupro 8085/86 CPU Card
- Jade DD Floppy Disk Controller
- A handcrafted wire-wrapped Serial & Parallel I/O and Speech Synthesiser card
- A parallel card with real-time clock
- Intersystems 256KDR
- A recently constructed EPROM Card
I have not connected an 8″ drive to it as yet, but it boots JADE CP/M 2.2 from a gotek. The disk images are from the original floppy disks.
