I might have been slightly out... I've had my Atari since the release of the STFM...1986... 24yrs... but i still love her. I love powering it up and seeing it boot from the 'new' internal IDE HDD and opening pictures and documents. i have old 'quotes and files' my dad made using this system using LDW power and Wordplus.....I kept backups of everything.
We didn't like the Mac (Dad and me), the PCs were 286/386 DOS crap, and the Atari had a colour screen. The beautiful SC1224.
(Mind you i still use DOS now and then, as you do)
I still have the invoice for the $1000+ 30Mb 'Megafile 30' HDD.
I seriously love building circuits... Mr Shredder, I had a friend years ago who bought a AT-once 8mhz mod for her STE.... to run some early IBM family history software. And she still does. The practice i had building pcbs and stuff for my Atari has been useful, didn't do it for a number of years, but knew how. Practice makes perfect..... hehe.
At-Once made a 386SX-16 board at one stage..... i'd love to have one now.... Could maybe run Win 3.1/95/98 on it!... My AT-Speed is 'only' a 286 like yours. But still good!
I'll send you the prototype board I made for the 'combo' high density/16mhz' um , kit... hopefully you can figure out the wiring to install it. It tests perfectly, but I don't think i'll ever make a production unit. I still don't have an STE to make a reasonable/easy diagram... but in theory it should be fine- no reason why it shouldn't work for you......It takes several hours to etch and build and test, and noone will pay the price for that.....niche market etc. Heck i have HD FDD boards noone wants! Weird.
Just use your multimeter, and trace some pins. i will help you.... no problem. It will work. I have your address to send. i made a promise to you.
Sorry to be so absent lately.... I have been very busy, and spending lots on my latest project, and my children....might get a result soon. Has cost me a small fortune. I am not permitted to talk much about it- but I will reveal much more if/when i get it working. (No its not Atari related, but I have had to relearn PIC & EEPROM programming, construction, and talking to many experts in their field. Seriously big poo. When I get serious about a project... I am all guns. You might have noticed...
I can't even spare the time for my Atari..
But it might be considered WAY off topic. PM if your interested. But I do play with the old ST when I lose 'focus'.
I love you all, and wish you the very best of luck in your own projects. I come here to be impressed! Nerds we are!!!! We're getting old!!!! hehehehe
Mr wongck, Don't sell your parts.. You'll regret it later. Put them in your cupboard and wait for another day. We are dealing with rare and hard to find components.
I am always here. You are my only friends in the UK... and maybe some in the US, or elsewhere. I love our talks. I can't believe this thread has hit over 5500 views! WOW.
Cheers guys. You are all amazing. Just keeping in touch.
