At boot the AT will look for and ROMs with the correct signature at the start and will then "hook" the BIOS on the adapter card to the system BIOS. I had a ver

Mr. Emmanuel Roche, Fran… says: Intrigued by the name BUTLER FLATS ASSOCIATES, I made another search. This time, I find that this company was created in 1984 (hence its mention in BYTE in 1987), but closed in 1990. However, I found the name of its President who, apparently, still lives in Rochester, MA, if someone living nearby wa

Z8K SBC and CP/M
Roger Ivie says: ...That's not quite what I said. What I said is that the CP/M BIOS doesn't *have to* depend on PC BIOS. If you're on a platform that has something like the PC BIOS, it makes sense to use it. If you don't have a PC BIOS, you don't have to write one to make CP/M run on the platform.

Disposing of some CP/M stuff
V1050 says: ...Oh well, thanks anyway. I won't ask how it was disposed. My Visual Technology V1050 used to run a daisy-wheel. At this time i'm wondering if the Wyse terminals would function as backup or replacement for the stock terminal that came with my machine. It's driven by CP/M Plus (3.0), a Z80 and a ded

Ed says: ...Reminds me of 8086 MASM/TASM which are very fussy when it comes to datatypes. e.g. one can define BDOS as constant/offset and do arithmetic on it but when CALLed, one must add the base address of its segment to it - even if that base address is 0000h.
