Yet I managed to buy on=20 e-bay an Amstrad PC2086 here, so in theory, I should be able to continue=20 from here too. The machine itself came in a very bad shape, the keyboard=20 is broken, FDD and original MFM HDD are also dead. Fortunately, I've got=20 one more XT-IDE 8-bit ISA card and an CF-IDE adapter. It's the only=20 workable boot device this machine currently has. I've compiled ELKS's recent git master and copied boot image to the 32MB=20 CF card. While configuring the build, some progess I've noticed in the way = HD image is configured (CHS geometry can now be given through menuconfig). I tried to boot the image, but all I could see was: MINIX boot 3! Press key. Some specs of this machine: - CPU: AMD 8086 - RAM: 640kB - Video: Onboard VGA Paradise - Serial port: Onboard Amstrad 40049 inherited from Amstrad Portable PC=20 line (I hope it's compatible with 8250, not sure where to find more info=20 about it) - Amstrad-specific keyboard and mouse (not compatible with anything else=20 and not repairable when broken) - Onboard Zilog 765 floppy disk controller I've removed MFM HDD controller (8-bit ISA card), as there's no use for=20 it.
