RTTY Folks,
I've setup RITTY on a wide selection of laptops including most of the IBM
Think Pad series, Toshiba's Dell's, the older Sony Viao's (I have a new
FX-240 that is stubborn) and it seems to work fine.
Brian has expanded on the sound card that are compatible and has added
a feature where you can use an external mixer program.
Borrowing from the RITTY.DOC manual (Copyright 2001 by Brian Beezley, K6STI):

---- SOUND CARD ------------------------------------------------
RITTY works with most sound cards, but a 16-bit Creative
Labs card (non-PCI bus) works best. Other cards may provide
inadequate input/output levels, offer only coarse level
adjustment, or exhibit limited dynamic range.
RITTY displays sound-card A/D resolution and mixer type
at startup. "Full mixer" means a CT1745 or equivalent mixer
chip with complete source control and 40 level settings 2 dB
apart. "Partial mixer" means a CT1345 with eight 6-dB levels
and no mic input-level control. "Primitive mixer" means a
CT1335 with no source selection or input-level control, and with
eight 6-dB output levels. (Cost-cutting, depopulated cards may
exhibit fewer levels and coarser steps than these design specs.)
If you find RITTY's mixer control to be inadequate with
your sound card, you can try an external mixer utility by adding
M to the RITTY command line. This option internally disables
RITTY's source and level controls.
RITTY uses the SET BLASTER statement to determine sound-
card hardware settings (I/O address, IRQ level, DMA channels).
You may need to configure your card to these settings by
executing a utility such as DIAGNOSE in AUTOEXEC.BAT or CTCM in
CONFIG.SYS. See your sound-card manual for details.

I think that only one of the IBM's had a true Creative Labs chip sent. All
others were some kind of knockoff. However, the "SET BLASTER" command and
the "RITTY M" option sorted these out.
Go with the older models (more than two years old). These devices are more
likely to work and to have the available external mixer software in DOS
format. In most cases RITTY can do some basic control even with the most
"primitive mixer".
Hope this helps.
73 an Aloha,
Walt
