So, I'm just messing around tonight.
But perhaps some of you may find this interesting. (Like whatever
For fun, I decided to mount my 'SuperMon' cartridge roms internally. Like since I'm only using sockets Lo-0, and Hi-2 for my current IDE adapter, and the future MultiTOS-ROM board.
I thought, "Why not mount the Supermon ROMs internally on their respective, and now basically spare 'TOS' Lo or Hi sockets, and then rewire the ROM4 select to their CE pins." I used Lo-2 and Hi-1.
The rom4 line I stole from the motherboard off a via. (Remember it is generated by the GLU for cartridge use)
Then additionally, I can plug in the Dallas RTC chip to the remaining Hi-0 ... ala d8-16, socket (like it was in the cartridge)
I didn't just rip up my nice little cartridge- I only removed my now socketed RTC chip, and then burnt a pair of blank 27c256 ROMs lying on my shelf with Supermon code.
Its slightly wierd, but it turns out, the dallas chip mirrors all the Hi datalines on its socket, but Chip select (CE) gets diverted through the dallas chip before it reaches both
the normal ROMs.
This is how its wired in the cartridge. I also didn't bother wiring OEs to the LDS/UDS pins like they were in the cartridge.. just being grounded is fine. Like the rest of the OS ROMs like usual.
So for now, the debug/RTC 'cartridge' is internally mounted. And I'm happy with that. And it reads the clock time nicely. (Using also the y2k-fix program for patching)
I've had the idea for ages but haven't bothered to do it. I'd rather just plug the dallas chip by itself into a TOS rom socket- and have a little program find and read it.
For now, I need Supermon to run from the cartridge 'address' range and do that job for me. (But it has other benefits too)
So for sh!ts and g!ggles, I loaded up Cab 1.5... No internet ability on my ST yet, and its probably silly anyway. (But I'll buy a 'simple' ethernet card off Zaxon when they are done... took ages to remove the hdd and load the stuff I'm gonna talk about next... ethernet would be neater.. and even possibly slower.. but I'm lazy)
Having installed CAB, I wanted to test it.... I have a decent 'offline' webpage of some stuff I decided to buy on CD for permanant archives a couple years ago. Just alternative health/energy info.. etc and more.
The folder is just over a gigabyte for all the files.. pics & all that...... so I loaded it to a 'spare' partition on the STs 80Gb drive. (With the PC USB-IDE adapter)
Lets give the modded ST a bit of a flogging. A massive html archive loaded from IDE.
Amusingly, It 'only' takes 10 solid minutes to load the 'index.htm' page.
Overclocked/Overscanned, and running off proper TwistedIDE.
Somehow I still have about 900k of free RAM when its finished loading/rendering/whatever.????!
Mind you CAB looks nice in Overscan. (Only Mono on my LCD monitor, but the picture fills the screen....love it when something works).. 688x480, on 19" LCD. Sweet.
Clicking on 'links' are reasonably quick and images are dithered as you would expect. Nice.
The ST has been powered up for more than 12hrs,,, okay most of the daylight hours- troubleshooting and otherwise..... I'm really happy.
Need to remember to play
with the Atari sometimes.
PS, Here is the current 'live' version of that website.. http://www.rexresearch.com/
Get lost in that.....
I've used a few ideas gleaned from the massive archive that is there....Amazing stuff.
