Clearbrook Software Group created and sold a number of very useful software packages. They were based in Abbotsford BC Canada, and Paul Kehler was their president and chief programmer.
I know I had a paper copy of the user manual for MSF, but haven't found it yet. If and when I do, I will create a separate web page for MSF.
In the disk image for Erina I found the string "Copyright (C)1981,1985 by SEIKOU". It's likely that both Erina and Serina were developed by Seikou in Japan, and that Clearbrook Software Group was merely a reseller for them. Interestingly, the EXCEL-9 6809 plug-in card for the Apple II was made by SEIKOU in 1981. And I found information (p.7) that in 1989 Microware purchased Seikou Denshi, a software company based in Tokyo that specialized in developing and marketing application software for OS-9. These probably all refer to the same company.
