No Slot Clock for TI-99

[aftyde]

Is there a 28 pin ROM that this device could be crammed into? https://www.ultimateapple2.com/catalogzen154/index.php?main_page=product_info&cPath=1_15&products_id=70

 

"The No-Slot Clock is a 'chip like' device that is installed in the IIe, IIc, IIc+ or Laser 128 under a ROM and keeps the time and date. It can also be used in the Apple II+, Franklin ACE 1000 or other Apple II clone with expansion slots (as long as there is a peripheral card with a 28 pin ROM on board), and some IBM PC's.

Please note that unlike other No-Slot Clocks, THIS version WILL FIT in a IIc or IIc+ with a Memory Expansion Card installed! It also allows for battery replacement with new, standard 1025 button cells, and even has connections for the ability to use other backup battery supplies.

The No-Slot Clock is ProDOS compatible (patch ProDOS or load driver on boot). The patch/driver work by alerting ProDOS there is a ThunderClock-like device installed. Some applications like AppleWorks will utilize the clock without any modifications. When the patch/driver is loaded Copy II+ will automatically recognize that a clock is installed and bypass the "Please Enter Date" screens.

Note: Please see the Forums for related support, discussions, documents, and software."

Even if there were ... presumably the device responds at certain locations in the processor memory map. Depending on where those locations are, it may not work because those locations are already used for (for example) VDP, GROM or DSR access, or it messes up software that expects and uses RAM in those locations. With the Apple, the device appears to be patched into the operating system - there is no such concept of the 99/4A.

In that case - what might the clock options be for the TI? I'd like to use the REMIND software, and it would be nice if BOOT displayed the time. I have scanned the binary files for evidence of device input - but still pretty new at this. Seems that if it's possible to hack 80 col support into BOOT that clock support should be easy enough. Right now the only source of time I have is HDX1.CLOCK, any pointers, suggestions or ideas?!?

There are several that come to mind: the MBP clock card, the TripleTech, the BWG Disk Controller. Tim Tesch's 80-col MENU program and even BOOT will display the time on the title screen. You can even time stamp disk catalogs(labels) as well.

Reading your posts here takes me down memory lane! In the end, it came down to buying a legacy card. While it's not much help, my suggestion is to keep your eyes open on Ebay.... sorry.

 

Yes, the HDX1.CLOCK is currently usable for BASIC applications, but then, as now, there is nothing that will convert the input into a usable format that can be used by existing E/A 5 programs.

 

I even did a blog on it << HERE >>. Good luck in your quest, mine lasted a long, long time.

I have a Speech Synthesizer with one installed in it. Have not used it in years since I use Classic99

Is that an offer to sell?

LOL - I was just wondering about that...

Well, he did say he uses Classic 99 and has not used it for years, so the fact that he mentioned it... you better send him a PM fast before someone else does!

Only ebay makes it fair.

I have a DALLAS DS1216 installed in a ROMOX cartridge but don't remember ever being able (or trying) to access it...

I do not think it works as when I last plugged it into the TI I could no longer access the P-Box and the Console would randomly reset or lock up.

I got it from Goodwill off a shelf of TI stuff with Joysticks, cleaned it up and inside it had Clock written in Magic Marker on the back side of Perf Board.

So have no idea how it worked, but it may have been using a DSR.

sounds like there have been some lost homebrew projects...

I made my own clock once. A card that plugs into the expansion box. This was before any of the commercially available real time clock cards had been launched.

My card is based on the MM58167A from National Semiconductor.

If it was built as a Clulow or MBP style clock, it would have no DSR. The clock registers are made visible in the 0x8600 range.

 

Thierry's site has a good write-up of the MBP and Analog to Digital conversion hardware.

I added a clock to a Speech Synthesiser yesterday evening. It's actually pretty easy to do, and you can access it from anywhere. I'll put it on eBay if anyone is interested.

Absolutely brilliant and amazingly simple to access. Would you happen to have schematics available?

Yeah but, can it core a apple?

I just wonder, with groundbreaking technology like that, is it still a TI-99/4A?

[mizapf]

Yeah but, can it core a apple?

 

And will it blend?

Oh Damn.. I have to have one. maybe someone could make a version that has a calculator built in too.

 

I love this thing...
