LisaList2

So once the LISA 2/5 and LISA 2/10 designation became apple lexicon, wouldn't that make the original LISA with five (5) megabyte drive a LISA 1/5 and ten (10) megabyte a LISA 1/10 - curious if others have heard this term used to define period hardware configurations.

Never heard it myself.

I tend to think of 1, 2, 2/5, 2/10, XL as being fairly informal terms. With the exception of "XL" it's mostly clear what they refer to, but they aren't part of a systematic naming system like IUPAC names for organic chemicals, say.

FWIW, my Lisa 1 machines do not recognize any 10MB ProFiles when attached. I do not know if this is a limitation of the Rev. C / D CPU board ROMS, the I/O board ROMs, or a combination of the two. Therefore a Lisa 1/10 does not seem to be a thing.

That's funny --- I'm pretty sure my Lisa 1 with ROM D is happy to work with just about any weird size of "ProFile" that I set up with a ProFile emulator.

IIRC all the boot ROM does is check to see whether a drive answers the basic handshake in order to try and boot from the built-in parallel port (or put the icon in the STARTUP FROM...) menu. Then when it's time to boot, it reads block $000000 into a spot in RAM and jumps there, and after that there's nothing more that the ROM does.

Checking now... The ROM (at least rev. H) only calls PROREAD once with a block address of 0. So it should work with any "ProFile" from sizes 532 bytes to 8.9 gigabytes...

It wouldn't surprise me though if earlier versions of the Office System and Workshop didn't recognise any size of ProFile besides 5 MB.

(Have you tried Office System 2.0? It's the latest that runs on a Lisa 1 as far as I know.)

Ooh, that's a good question. I am definitely speaking of LOS 1.2 only. Will try LOS 2.0 and see if anything is different.
