I may not be the first to be confused.

You say you have an STfm, but mention having 30pin chips (Simms?) There is the confusion. A STfm doesn't have that configuration.

Perhaps you could could post a picture of the motherboard to ease the true identity of the board.

ST.

Hmmm, 4 banks of 128k.

Plus a single 64k bank of Boot ROMs for a boot loader/selector seems likely.

=576k.

Multi-cartridge board. (Not TOS, wrong range...) Rip the ROMs out of your 'single' cartridges, and plonk them on this. Select on boot. Nice.

This is a kind of discriminatory pricing, and for many businesses it's essential for their survival. You've seen discriminatory pricing if you've ever bought something with a coupon that you might not otherwise have purchased at the higher price. . . . By disabling part the of chip, Intel is causin...

I totally accept that. Somewhere my point was, if they can afford to sell a 'poverty/cutdown/disabled' versions of a design to the masses on purpose, then the R&D is wasted... Intel (as an example) is happy to sell MORE reduced spec parts at a lower cost- than offer everything the design mask can do...

CPU/GPU binning is a pet peev of mine. Lemme explain... I understand that testing often shows defects, and a solid design will allow disabling of sections in non critical areas. Like lose a bit of cache... gain a still usable chip. Also clock speed vs temp vs stability- will vary with the quality of...

And if you look at it, the question of how to fit a MegaBUS or VME slot to an older ST is answered.

I've said before how much I love the PicoPSU.... can't wait to tell you why.

Muhaha.. Nice job there man... Might have kept a spare molex for internal drives though.

Maybe this will help? http://www.cafepress.com/atari_st_bombs Just who thought to go and make those... :lol: , but seriously).... 4 bombs, Illegal Instruction. Hmm. Seems odd, I should check your other thread... but do you have only the one set of 2.06 ROMs to try? Have you tried removing and reseat...

Next step? Now you sound like my 5yr/old daughter. "What next dad?" .. usually I give her a paint brush, or the mouse and google. Kids these days......... I guess I'll have to make a proper tutorial on ROM burning and splitting.... I covered the basics- maybe we need pictures and details. Why, beca...

I'd agree Mark. Adding a Mega compatible header isn't out of the impossible... But we can't get away from having to solder something. I've taken a bit of leave from ST mods & hardware until Winter.... not far off.. grrr... There is much I want to achieve before then. I love multiple projects, but da...

About the burning ROMS subject... If anyone is only interested in improving his system with a new official TOS...he can go to the EPROM burning, isn't it? I mean, do Flash ROMS need any modification to fit and work in our systems? or can they just fit and work as well as EPROMs? Depending on the an...

I think so.... it can be slipped into ROM.. and would naturally be a later version I assume than in SuperTOS. http://myaes.lutece.net/ You may recall the thread Bid started on creating the ultimate TOS from all the fragments of patches around. I wonder what the person who compiled the current 'Super...

Soft Patching might even fall under our first catagory. 1.1.3 Software patching for speed and improvements. NVDI is I guess the most well known, The improvements in speed are very impressive. Plus there is extra fonts too and other things. QuickST is another- mainly focused on speed. Both these prog...

For a bit of info, its otherwise well documentated A very special function of the GLU chip. A unique 'shadow address' When the Motorola CPU first gets power and does its thing to initialise and get stable. Its first job to to read the very bottom address. The GLU chip is powered by now and waiting. ...

Okay, Lets go with 1.1.2 for the minute. Unofficial TOS ... Now this isn't my area of expertise.. but.... I know this. EmuTOS , and KaosTOS . Both intended for the lower ranking STs. Blow some ROMs and they will run rather easily. How good are they... dunno. Both versions I have are German, and afte...

I'm writing this reply offline- damn power keeps going out. Write a bit and save...etc Here's a guide to ROMs in the Atari the best I can explain and simplify it. I'll reiterate what you probably know- and expand on it. The old STs, STacy & Mega use TOS 1.0 to 1.4. There are plenty of threads that d...

Have you not an old video vard gpu cooler, or somthing out of an old lapptop.

I had a little fan/heatsink once, probably less than 3/8" thick, and large enough to fit 68030.

The really cheap basic video card with their neat HSF combos would be a treat no?

To help a bit.. um here's a quick picture of a pair of my dirty old cases. One Original, the other modified to fit an off the shelf PC floppy drive. The face of which will sit just behind the Atari case. Clean and neat. IMG_1539s.jpg I'll have to do a shot of the lid fitted over the drive to show it...

A number of times- Ive seen similar screens during mucking about with my half dodgy sockets and ROM experiments. Sometimes I get the Fuji and a hang... sometimes white screen... Results vary. Always I've found a bad connection to at least one pin of the ROM. (You've even tried a different set) Are y...

LMFAO Seriously, Some days you kick yer self. :mrgreen: Imagine, for a second. The amount of Sterilising crap for home brewing. Well... not that much actually. But, I use Sodium Persulphate... very common, from NapiSan to Proper 'Food' grade stuff. Wash everything in a nice hot batch, then hot rinse...

Wow my grammer was bad the other night. Spelling errors everywhere. So Glad its working for you. Excellent. :cheers: To answer your question... Desk Accessories, or *.ACC files are special. They are the core of the basic Atari 'multitasking'. You can basically load six. (Stay quiet you lot)... they ...

Its all good Nativ, He has the adapter and the C16. Ok... Can you try setting the MegaSTE, to 8Mhz and Cache Off. Then try again. The C16 is designed for ST... not MegaSTE 16Mhz. I think you need a cpx / xcontrol panel for that. My C16 will not operate if my ST is overclocked.... You would think the...

A stab in the dark possibility. That Diode is to a lifted Pin 40. Which is power for the DMA chip... the diode would drop 0.2v across it. It might be that 'other' signals coming in were a bit weak and the internal comparators didn't see them as logic 'high' enough causing corruption. Dirty hack to f...

I'll attach the latest I've got, and the latest I know of. AT_SPEED_350.zip Now maybe, something to consider, There is a Files called AT_Inst.PRG, if you haven't already seen it. It is for configuring the emulator. (Harddisks, Mouse mode, Graphics... ) Possibly the screen mode is wrong and that is c...

Is it fitted with oneof these?

And is your software v3.5?
