Re: Sharp PC-3000

Yes - I resented paying £40 for just 128Kb (!) at the time especially as I had forked out £38 for the user manual a bit earlier from them! BUT the problem with the PC3k was that finicky Laplinking and a realistic connection success rate of around 10% ONLY. This was exasperated by the fact where I wo...

Re: Sharp PC-3000

Yes, from what I remember in the days of struggling to get affordable PCMCIA cards for the PC3000 I remember that SRAM work at 5v because they already have a battery charging their circuit. In 5v Flash cards, there is not enough voltage coming from the PC3000 to WRITE to the card in continuous strea...

Re: Sharp PC-3000

..no 3.3V - I am actually referenced in that Sven post by the way, as well as my original website! - I was an original adopter in 1995 and wrote a comprehensive case study on the wider usage of the PC3000 for Dip themselves. I used to go into their offices in Guildford and was the first person to be...

Re: Sharp PC-3000

One main reason for ATA Flash not working in the PC3000 was that it had to be 3.3v and not 5v as the later cards are. Strangely, you can now find new 3.3v cards which are still used in industrial applications - like CNC equipment controllers etc. Here are two companies selling 3.3v compatible cards ...

Re: Sharp PC-3000

the holy grail for PC3K users of the day - Running Windows!

Also runs Word for Windows and Excel for Windows without issue.

Seeing it load Windows still gives a buzz - I don't even mind the hour glass!

Re: Sharp PC-3000

I was going through all this from as far back as 1996! - In fact I hoped I would never have to again, but I hate seeing my once loved and vaulted machine languishing in a drawer - 'dumb' has gotten the better of me - especially as there seems to be a big buzz around this and te other contemporary DO...
