Is there a way to mount two .image volumes formatted for use by the ESProfile so that files, System Folders, etc. can be copied easily between them?

CiderPress does not appear to recognize the volumes.

Could a second ESProfile be used in a 2/10?

You can definitely have two (or up to seven) connected if you have enough parallel ports. I'm not aware if something like Selector on 2-7 would be possible, since that's only brought up on the boot disk. Though, I suspect someone with some programming skills can probably write a Mac program to select a drive image on the others?

You should be able to boot from each drive in turn, S(elect the desired image from the Selector, and then quit the Selector and move onto the next drive until you've selected images for all of them. I had to do that recently when I ran out of space and had to transfer all my LOS compilation stuff from a 16MB to a 32MB Workshop volume!

So I can just get an external ESProfile, attach it to a rear port and it will mount a second volume?

If so that is exactly what I need.

Who has an external ESProfile to sell?

I am not sure I follow. How does that allow me to have two volumes mounted to the desktop at the same time to copy between volumes(images) with only one ESProfile?

Oh sorry, I didn't know you wanted to do all this with just one ESProFile unit! Unfortunately that's not really possible; you've got to have one ESProFile for each drive that you want to have mounted. Sorry for misunderstanding!

All good!

Some off-topic questions: I was looking up ESProfile stuff on your GitHub, and you did an eclectic car project. Was it a full-size car?

Ahh, yes, good call on this process. Hadn't thought of that!

Oh yeah, I forgot I had that thing on there! No, it's not an actual car that I converted to be electric or anything (I don't have that level of mechanical skill), but it's a small 6ft x 3ft ish thing that I made in high school and would ride around my neighborhood. I bolted a deck chair to the top for myself, and there was room for a passenger on the back if they wanted to stand up and hold on to the back of the chair, which is definitely pretty dangerous but actually worked really well. It was powered off 10s (so 36V) lithium ion batteries and could get about 1 hour of driving on a charge with the batteries that I had, so not too bad at all!

Note that the Selector has some untested scripting capability that may be able to automate some coordinated set-up of multiple ESProFile or Cameo/Aphid hard drive emulators.

Meanwhile, what's this about a 32 MB Workshop volume? I had assumed that it could only be 5 or 10 MB if it wasn't a Priam drive...

It doesn't work in stock LOS/Workshop, but you can do it if you patch the ProFile driver properly. I'm planning on revealing all of my progress with compiling LOS during a presentation at VCF Southwest in June (hopefully I'll be done by then), so I'll probably wait and share the details then, but it sure comes in handy for fitting all that source code on a single volume!


And interestingly enough, you can actually use up to a 16MB ProFile (or really closer to 15MB if you exclude the tag bytes) without the patch! Just make an image of 30,000 blocks or smaller, and it'll work fine.

[stepleton]

Fair enough I guess, but I find this kind of proprietary "I've got a secret" posture... fairly motivating. I might try to find out how to patch the ProFile driver, and if I work it out between now and June, I might spill the beans.

Don't worry too much, it's not long till VCF SW and I'm busy.

[AlexTheCat123]

I totally understand; I find the whole "secret" thing really motivating myself! And as you can probably tell from everything that's freely available on my GitHub, I don't normally like doing things this way where I keep everything a secret. It's just that this is a pretty massive project, and I think it would be a lot more exciting to reveal it all at once at an event like this than to reveal it piece by piece along the way. And besides, I'm not even done yet! But rest assured that I'll be sharing all the details and files that I possibly can once that date comes around so that everyone else can replicate things! I hope that all makes sense.

Please tell me this secret doesn't involve writing a Monitor/Workshop executable emulator that intercepts "syscalls"/traps in order to map them to standard POSIX functions, allowing the old tooling to be ran from a modern command line with full access to the local filesystem (ala https://github.com/ksherlock/mpw, https://github.com/eschaton/MINIXCompat, etc).

No, it doesn't; even though it's painfully slow, I made a rule for myself that I have to do everything on original hardware without any modern emulators or other techniques (aside from a hard drive emulator) to help me along.
