Thanks Rob! Yes, I was using CTMOUSE with limited success, except in Mouse Systems mode. I switched to a Microsoft driver but didn’t try version 7, I had a copy of 6.24 and a couple of earlier versions. Switching to DOS 6.22 has solved that so I just rolled with that.

Just to clarify, the 4-in-1 design includes a Real-Time Clock as the 4th item, not a Parallel port. It also was switched over to a mostly SMD design rather than Through-Hole parts.

The 3-in-1 Version 2.0 includes a multi-IO chip which adds a second RS232 as well as a full Parallel port. I still consider it a 3-in-1 as the 2 serials and parallel are all handled by one main chip.

Unfortunately, nobody has taken up the task of building either of them for sale. Only the original is being sold by a seller in Canada right now.

What mouse driver are you using under DOS 3.3 that does not work with Microsoft mode mice? I ran into a lot of issues with CTMOUSE under earlier DOS versions, so I started including MSMOUSE 7.0 driver instead.
