You can get away with slower PCs just fine if you burn at slower speeds and have nothing else running. You may need to create an intermediate ISO file that you burn instead of on-the-fly, but the HP/Ricoh will work on the slower models for CD burning. CD reading? It doesn't matter how slow your PC is, it will always work. Had a 4x Yamaha 100 SCSI drive running off 100Mhz PCs years ago under Win95, so you should be fine with the HP/Ricoh even on the L50 at 2x. > These drives are 4x write and re-write... which make them workable for a > <400MHz CPU.

The big difference in faster, modern CD-RW drives is the BurnProof/JustLink feature which prevents coasters (bad burns) even when the data stream stops completely for seconds/minutes until the HD can catch up. The HP/Ricoh has a generous 2MB buffer, but that'll only prevent coasters for a few seconds if data stream is interrupted. Thus, the newer drives can successfully burn at any speed regardless of PC speed; older ones depend more heavily on CPU speed. > > Anyone have a L50/70 and can say what it needs to see the PCMCIA slot > >under DOS?

Natually, older CS drivers won't support the latest strange PCMCIA cards out, but they will certainly support as many of the older cards you will generally use. > Can I equate "card & socket drivers" = "C&S driver" = "CS driver".

CardSoft is the DOS version of one available CS drive. CardWizard is the Windows version, some of which also install the DOS drivers, but not the latest versions. > >As I recall, even the L50 or L70 web pages in Japanese showed a Libretto > >CD-ROM drive being sold by Toshiba as an accessory. > > Huh... have you seen the EXP Traveler 2020? > > It's a pretty clunky beast, but it's been working pretty well.
