What was the +45V for?

I might have forgotten about MODE, but HELP and GeneveOS didn't!

Does anyone know of a program that will let the Geneve speak from the command line, something like: CALL SAY("HELLO")? Is there a file handle for the RS232 or PIO so from the command line you can send a string. copy con RS232 (not sure if this works at a particular baud rate)?

Anyone want to hazard a guess as to why TI didn't include locking lugs on their rs232? (O'Why TI!) The ones on this card are self installed.

Someone snuck that upgrade in. 😃 I've been watching that page like a hawk.

I've not seen or noticed this before, but nice feature on upload:

I can't contain myself... I was looking at the source code to exec a while back, and that's the most far out code, I've ever seen.... Worth a look by one and all.

If something can be plugged in backwards, I've probably done it. When I have something that can plug in multiple ways, I take a silver sharpie and mark the top of the board and top of the connector. For future reference @jedimatt42, can you take a picture of the board and highlight the chip that gets fry-ed?

@mizapf -- "Ninermame ... all you ever wanted to know about the TI-99 emulations in MAME" In my defense, I looked here first. InsaneMultitasker has convinced me of the power of pushing bytes to the RS232 port for debugging. I've seen very little on the topic of MAME and serial ports, can you explain in a "MAME RS232 for Dummies" way - how I setup an RS232 and where the bytes go to under MAME?

FPO, Spent about 6 hours this weekend getting a MAME Geneve and a real GENEVE updated and booting with MDOS 7.4 and all the new Utils. Was thinking it would be real nice to have an all new hardware geneve!

Running mame .256 on Windows 10, "CALL SAY("HELLO")"works for me in GenMod mode with MDOS 7.4 and Abasic 409 (The cleanest ABASIC ever 😃 ).

Thanks @Ksarul for rebuilding the manual. I took some tentative steps towards replacing battery holders on my 4000, testing and then upgrading the memory, and discovered the copy of the 4000 manual on whtech is almost unreadable. I'm sure redoing the manual was a lot of labor.

Hi, I've not really kept up with the development of MDOS support for the TIPI - just mainly using it as a mass storage device with network connectivity. But, what is this 4A limitation you speak of: >"This is due to a 4A limitation on the PAB of 64K with the opcode being used as MDOS is > 64K." Since the only mass storage I have sitting with the Geneve is the TIPI, can you ID what I would need to change, in order to build to a floppy drive?

@InsaneMultitasker received the same error. started with MAKE HDOS,F - It starts, I can see it reading TIPI and then it just stops. That's after upgrade to 3.19 on tipi. native_dirs = GIT. clone MDOS delete .git from tip1.git.mdos using the latest GDM2K to copy to TIP1.MDOS. MAKE HDOS,F {Head Scratch} I noticed, the assembler was saying #0101 John Birdwell. I modified my path to just be I: (no other directories). I restarted with MAKE HDOS,F This time, I received, don't know how to make ZZZZZZZZZZZZ. But, it didn't lock up, and I'm being told assembler is #2000 MDOS Developer. It did complete this time, but no HDOS was created?

As an aside, When cloning a repo, it's probably best as soon as you do the git clone to remove the .git directory.

Given what I have learned in the last week about TIPI and native_dirs, I decided to re-work things a bit. TIPI will now have a directory called GIT - it's will have native_dirs, I won't "work" in it, it will only be used for git cloning. The new cycle will be: cd GIT git clone https://github.com/BeeryMiller/MDOS copy contents to root of tipi and do things. GeneveOS build Question: In MDOS there used to be a command testh - it was a program that loaded a newly built HDOS. It was in the root of the build directory. Now, the only testh, is in the hdos, and it's a dv80.

Hey @GDMike --- super long time, no update?

Thanks @senior_falcon - One day, I might have to wire a hold button up, I was think Load Interrupt to a routine that would pool the keyboard and when a key was pressed return to executing a cartridge. hold/no hold is definitely the way to go!

I wasn't familiar with Texware, so I looked it up in the Cyc. Looks like they sold about a dozen programs mainly of the XB variety, written by different people. Sort of a small version of Asgard Software. Thanks @chris36 for sorting this out.

I'm reading Adventure, Atari 2600 and the author says he wished the 2600 had a pause button for when his parents called him to dinner. Could a pause button be created with a load interrupt button, and some software that just waited around for a key or a button to be pressed (32K needed)?

Has any one seen online a guide to refurbish a TI cassette player?

Do you know if the assembly language portion is embedded with the XB code - or is it hidden on the disk some where?

As a slight aside.... I am often able to look up corporate records from companies that are long out of business with much easy. Doesn't seem to be that easy to look through corporate records for those corporations, incorporated in DC.

Thank you both! @chris36 I had no doubt that the program dsk you attached ran. I was hoping someone had the assembly source. Interestingly enough the disk provided by @ti99iuc has a different directory: As all files show an extended basic listing, without drilling in further, I can only guess they have embedded assembly similar to what systex was used for. And the manual makes it clear there is both an extended basic version and an assembly language version. In any case, it might be fun at some point down the line to see if I can break it all down with TICodeED and then maybe try to assemble using something like GEM256. Thanks to both of you.

ISSUE #2 with GeneveOS Make. Next up was to test this with "real" geneve. ssh'ed in to pi. cd to tipi_disk git {mdos files} On Geneve: modified pi.config with native_text_dir = mdos. cd mdos make I started the compile - it didn't lock up, but didn't seem happy.
