Upon request, I have just now recorded me typing a short text on four different keyboards. I'm a bit sleepy, so speed was somewhat lacking, but I think it's okay nonetheless. I've been using the G80-3000 with green MX switches and the G80-11900 with black MX switches in the last few days, so I did have problems on the Unicomp.
The sound clip contains:
- Cherry G80-11900 with black MX, seconds 0-18
- Compaq (OEM'd Cherry) G80-11801 with brown MX, seconds 18-39 (just a tiny pause between the two, sorry)
- Cherry G80-3000 with blue MX, springs swapped to resemble green MX (except Shift, Return, Backspace), seconds 39-59
- Unicomp Endurapro with buckling springs, seconds 59-79
