Re: Sharp PC-3000

BR-2325s arrived and at least I don't get that annoying "card battery low" message anymore.

( Expecting to get the above mentioned Omnibook 800ct tomorrow. Will open another thread about it shortly and will keep posting here only what's relevant to the Sharp. )

Re: Sharp PC-3000

Wow, some hard-core stuff here! It is actually a very clever idea and I used to type in much much bigger programs into various 8-bit computers back in the '80s. I might even try this if the Omnibook doesn't save me! :) EDIT: I typed in your small example and it doesn't beep on my Sharp (yes, all sou...

Re: Sharp PC-3000

Great, thanks!

Now I am just hoping the HP Omnibook 800ct will be able to read/write both SRAM and the CF card.

Will get a 32MB CF card in the meantime.

Re: Sharp PC-3000

Thank you for keeping up with my frustrations :) I actually do have more Sharp-relevant questions. I read on your site: ... sharp can boot from PCMCIA cards. It can use Flash or CF cards (with a pcmcia adapter) but keep in mind DOS 3.3 can only access disks up to 32 MB (At least with the sundisk dri...

Re: Sharp PC-3000

Where to begin? Rebooted in DOS only (Wind 98 DOS Mode) and the card is not recognizable. Dowloaded the file from your link but it expanded into something which wants to create a diskette and I don't have a floppy drive. (The Omnibook which I mentioned will have a floppy drive so maybe then but I do...

Re: Sharp PC-3000

Reinstalled Win 98 2 times, tried every single combination, nothing works -- same situation. The SRAM card works great on Win and works great in Sharp but they actually corrupt each other's data (I tried with multiple larger files). Maybe another next step is to get the card with "attributes&qu...

Re: Sharp PC-3000

I already had the LASTDRIVE=Z line. I commented out the DOS driver, rebooted, and the card is now unrecognizable and attempting to FORMAT it results with "divide by zero overflow". Putting the driver back reverted the previous situation. TRUEFFS appears to be installed -- there is a TFFS9x...

Re: Sharp PC-3000

I did all you said -- same result. The computers don't see each other's data: - if I format on Sharp and put one simple txt file on it: -- Win 98 sees the card as valid -- Win 98 sees the file name as a single non-ASCII character and the size of the file as 0 -- if I add a file using Win 98 on such ...

Re: Sharp PC-3000

I got the Win 98 and, after lots of juggling, was able to dual boot my T42 (I removed 1GB just in case). It's complicated if you install XP 1st (like I did) because Win 98 chokes on NTFS. The process was: boot 98 DOS from CD, do fdisk magic, install Win 98, boot XP CD, repair XP (to create the dual ...

Re: Sharp PC-3000

BR2325 is just another alternate name for cr2325. Yeah, knew that but nobody had the CR-2325 either... The problem you describe sounds like a weak contact problem. [...] I would try the coin trick first. Sounded reasonable and here is what I discovered! Coin was too big to fit, I put folded tinfoil...
