Meeting today?

I used a simpler version of it BITD to sort out some three-keypress sequences that were misbehaving. It's also interesting to see some of the differences between the old console and the QI; especially when it comes to the joysticks.

Let me see if I can get this link to work. This might be useful to you, KeyBits lets you see the keyboard/joystick interactions directly: Sometimes you may want to scan a key or two directly from the keyboard in your software rather than going through the TI KSCAN routine. This routine, that loads into cartridge ROM, is a quick and easy way to identify the key column and row that you can use for directly addressing the TMS9901. Also see Thierry's page on the TI keyboard implementation for a good rundown on how it works. Just another tool in the tool set. And, yes, the columns are listed vertically and the rows are listed horizontally ? KBCART.bin1.49 kB · 65 downloads KEYBITs.pdf555.88 kB · 73 downloads

Thanks for doing this, @visrealm. A solution like this has been needed for long time for all of the broken Mitsumi keyboards out there. You've done us all a great service.

Yeah, I'm not seeing it there either and I've also been looking for it. I'm definitely missing something, too.

Does anyone here actually program x86-32/64 in assembly? Reading the Hackaday article regarding real mode and the Wiki on the instruction set, its mind boggling that the human mind can work with 3600 some odd instructions and juggle memory management! There must be some pretty good toolsets out there or something.

I haven't unpacked all of my stuff since the move so I'm not able to get to it. I do have this PDF in my archives; it needs to be verified that it is the actual switch. GF-126-0018 TI PSBoard switch.PDF

Lee's explanation on how SAMS cards greater than 1 Meg need to be addressed is spot on. It is probably smart to just assume that any software that is written for SAMS is for cards that are over 1 Meg and that would make it universal for any SAMS card. SAMS registers explained_Srt_AP edits.rtf

Yes, thank you Fred! Outstanding!

I've been using the Wathai 110V 115V 120V 220V 240V Brushless Fans <80mm x 25mm> from Amazon. They're an easy replacement and are about (subjective here, mind you) half the noise of the OEM fan.

That's a good one!

It's my original 80k GramKracker. I just have it sitting on the fire hose connector.

Like finding lost treasure. I combined this cartridge back in the 80's because at the time I was using these cartridges the most during programming. I located it again years ago, but it was subsequently misplaced in a move. Rummaging through boxes I found it again! It's not so significant anymore with all the new cartridge choices we have but it was handy BITD. Just sharing for the fun of it. 20240217_111330.mp4

You must be talking about someone I used to work with <lol>, did pretty much the same thing. To add insult to injury, he would routinely throw his empty can of sardines into other people's trash cans.

There's a lot of truth in that. When I started, we had an incredible engineering guide book that was an absolute treasure. It covered wiring, connectors, schematic generation, component selection, environmental considerations, etc. Sometime afterwards, it disappeared when the organization "re-organized." If you weren't one of the lucky ones who kept a copy, it was lost to eternity. Unfortunately, those were the days of the typewriter so there is no online copy, at least not that I've found that has been uploaded. Over the years that followed I could see the new engineers coming in repeating mistakes and relearning the hard way because they didn't have the benefit of a mentor or proper guidance. I called it the "divide by zero" problem, when will we ever learn? 🙂
