Stuart Posted February 4, 2017 Share Posted February 4, 2017 Been having some fun integrating a couple of programs into a single 8K cartridge: -- The MiniMem Line-by-Line Assembler (LBLA) - no more loading from tape. -- The TIBUG monitor from the TM990 CPU module. This is similar to (and a fore-runner of) the Mini Memory EASY BUG and the Editor/Assembler Debugger program, and enables you to run and tweak the program you've just entered using the LBLA. -- The TMS 9900 disassembler from the Powertran Cortex. Full details and a download link for the EPROM image here: http://www.stuartconner.me.uk/ti/ti.htm#minimem_lbla_tibug_disassembler_cartridge. I've tested it using Classic99 and JS99'er, but not on the real hardware. Stuart. 9 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted February 4, 2017 Share Posted February 4, 2017 Nice... I will try to test on real hardware this weekend if I can.. I have a few honeydoos to get done before I get to be let loose to play.... Quote Link to comment Share on other sites More sharing options...
palmheads Posted February 4, 2017 Share Posted February 4, 2017 This looks great! Nice combination of tools. Quote Link to comment Share on other sites More sharing options...

+jedimatt42 Posted February 5, 2017 Share Posted February 5, 2017 I popped it into the flashrom99... works great.Playing in TI bug, I see an issue though: the paging with the 'N' command doesn't work write. I observe some garbage line with a 'b' printed between every line, consequently the top has scrolled off the screen. I'm using my side port 32k memory cards, so there is no reliable initial memory state. .... a few minutes later... yep, in classic99 I can make the issue reproduce by using the memory-scramble-reset feature! This is very awesome though... I look forward to rolling the LBLA into my skill set. -M@ Quote Link to comment Share on other sites More sharing options...

Ooops! I've corrected that and uploaded a new version (the new binary image file has a v1_1 suffix). I'm not sure if the scrolling page buffer that the LBLA uses is going to be a pain when used with TIBUG and the disassembler. With the LBLA it is useful to be able to scroll back to see what you've done earlier, but not so sure you need to be able to do that with TIBUG and the disassembler, and it just ends up messing up the screen. Might look at changing that. 2 Quote Link to comment Share on other sites More sharing options...

Opry99er Posted February 11, 2017 Share Posted February 11, 2017 I probably missed it in my absence, but have we come up with a way to reproduce the SAVE functionality of the MiniMem cartridge without battery backed RAM? By this I mean a cartridge containing RAM that can be written to via BASIC? Quote Link to comment Share on other sites More sharing options...

By this I mean a cartridge containing RAM that can be written to via BASIC? Not that I'm aware of. That is a handy feature at times... I imagine that requires a GPL based DSR, if it is going to be in a cartridge. I imagine all the necessary hardware required is probably there in the UberGrom. -M@ Quote Link to comment Share on other sites More sharing options...
Opry99er Posted February 12, 2017 Share Posted February 12, 2017 That was my thought as well... I wasn't sure about the software to flash the RAM within the cart though... Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted February 16, 2017 Share Posted February 16, 2017 This is what I have been wanting for the TI for a very long time. I have used 6502 machine language monitors (as they call them) on the Commodore 128 (built-in) and 64 (Warp Speed cartridge) and have longed for one for the TI. This is it, and even better as you can use labels. Fan-freaking-tastic. Now when I have an idea I can quickly whip it up and try it out. No more XB mock-ups for me. 1 Quote Link to comment Share on other sites More sharing options...

Isn't that what the SuperCart gives you? http://www.mainbyte.com/ti99/supercart/supercart.html (I think Ksarul has laid at a new PCB for it?) I've got a program that will load/save to that RAM (CART_RAM on http://www.stuartconner.me.uk/ti/ti.htm#miscellaneous_programs); some other versions exist as well. Should be able to peek/poke to the RAM from BASIC using the E/A functions. Quote Link to comment Share on other sites More sharing options...

OLD MINIMEM loads it again. It's like a single file thumbdrive for BASIC programs. Or did you mean something else Owen? -M@ Quote Link to comment Share on other sites More sharing options...
