WOW!! I Have one of those ETI boards, and I based my final Electronics Engineering project on its big brother, the 65F12.
>From memory, I spent days trying to understand why you had to issue a HEX 1800 MEMTOP command before using the disk. ETI Suggested that it was because the system had to know where the top of memory was, but it was because of a bug in that version of the kernel. The 65F11 had all of the headless primitive in kernel rom, and used a development ROM that contained the higher level words. I Loved the concept, but the silicon was expensive and as it turned out, rara. Nobody knows anything about these chips. At Uni, we hav Novix NC4016 dev boards with FDD support - they were FAST... One cycle could see the CPU read the next instruction, write a byte to the stack, and write a byte to I/O - all because it used three (or 4) separate busses. I'm here in Australia, and would merrily give it a home. :-) Kindest regards, Doug Jackson em: [email protected] ph: 0414 986878 Check out my awesome clocks at www.dougswordclocks.com Follow my amateur radio adventures at vk1zdj.net ----------------------------------------------------------- Just like an old fashioned letter, this email and any files transmitted with it should probably be treated as confidential and intended solely for your own use.
