8271 Disc Interface Upgrade Kit for BBC Micro
|Each kit contains:
Genuine Ceramic new-old-stock Intel 8271 Floppy Disc Controller
2 x 7438
2 x 74LS393
2 x CD4013B
DNFS 1.20 chip
The microchips are supplied in a handy reusable box and the kit comes with full fitting instructions.
NO SOLDERING is required to an Issue 4 or Issue 7 BBC Model B. All you do is plug the chips into the sockets provided on the PCB, move seven links and cut one further link.
For issues 1, 2 and 3 a slight modification is required which involves soldering and needs a short bit of insulated wire which I will supply if needed - please specify when ordering.
This upgrade kit is not intended for the BBC Model B+ but I will adapt a kit for use on the B+ if anybody needs one.
