Re: [M100] Programming languages for the Model 100?
MFORTH opt rom source is public so you could look at that. http://www.strangegizmo.com/products/mforth/ Steve Adolph with REX/REXMGR is the one to most recently create an Option ROM. You could ask him what he has as far as a Option ROM template. -- John.

Re: [M100] Programming languages for the Model 100?
John My plan is to create an OptionROM so any boiler plate code, guidelines, etc. would be most welcome. I am still planning on exploring the SmallC route, but I've already started coding in assembler and am quite liking it :) Certainly 8085 is a lot easier to get in your head than VAX Macro-32!

So I'd say it's a few things: a) Bugfixes/improvements over time b) Different ROMs, different names. c) Application specific hardware interrupt handling (software interrupts / effectively custom instructions) b) ISTR there being some nooks and crannies where you could insert code. So some variability may just be that they have application specific code packed in between system critical stuff. -- John.

The Secrets of the Option ROM Revealed by Mo Budlong It exists at my house. Mo also wrote RBASIC. The main takeaway though is the boilerplate assembly code which you base an OptROM on, switching, and calls in/out of optrom to the main ROM. The boilerplate code inlcudes the ROM portion of interrupt handlers that need to be present since when the OptROM is switched in since interrupts can happen any time. It also includes the installation code. Steve and I worked a bit on the shell and maybe the call code. If anyone wants to write their own OptROM I think we can get you some code. -- John.

The developer's wife stayed in touch with the list for a time after he died. If you can reach her, I don't know her email, she might be willing to sell copies. At the time we last obtained copies we were able to get them for $50 a pop, which was an excellent price. RBASIC is still an excellent tool. Unless someone would like to develop a dedicated 8085 output C compiler. There are 8085 C compilers, but they have to be run under a Z80 emulator. Don't forget the excellent assembly compiler in VirtualT. Frederick Whitaker On 6/11/2015 10:52 AM, John R. Hogerhuis wrote: I don't know. I bought a legit copy a few years back.

Re: [M100] Programming languages for the Model 100?
I can get SmallC running under Linux. This generates a SmallMAC (an 8085 macro assembler) input source file. I have the source code for SmallMAC which is also written in C - I should be able to get that running under Linux also. The remaining steps, as I see them, are as follows: 1. Post-process the object files that SmallMAC genarates into a format readable on a Tandy 102 (or at least burnable). 2. Provide enough c-library functions to interface with the hardware - screen, keyboard etc. 3. Provide a suitable C startup file. 4. Ideally programs would use suitable sections so that they can be split between ROM and RAM. I have done all this in the past with a different compiler targeting a single board 68k computer. Hopefully the memory overhead would be acceptable to leave enough space for reasonable sized programs. I was wondering if you can call the ROM routines from an option ROM? Regards, Mark.
