My first 8bit CP/M machine was made by putting a Microsoft Softcard into my
Apple ][ Plus, early 1981.
After sitting there for a few years, the Softcard was moved to a new Apple
//f. That's an Apple //e, where I had the Rom software patched by my dealer,
to prevent the hard reset routine from overwriting a few bytes in every xx
KB's. And, of course, the startup text on the top line of the screen changed
to Apple //f to make it my "personal" machine.

The //f machine was upgraded with serial and parallel cards, a
clock/interrupt card, extra RAM, and finally a SASI interface card,
connected to a 10 MB Xebec harddisk. For that SASI harddisk, as sold by my
dealer, I wrote the boot prom, patches and drivers for Microsoft CP/M 2.2,
ALS CP/M Plus, Apple DOS, Apple Pascal and finally Prodos.

In the end, it was a system that could run not only two flavors of CP/M, but
also all other OS's that were available for the Apple - all with megabytes
of harddisk space. CP/M Plus was my favorite OS as it was the fastest one,
mainly due to the large numbers of disk buffers that were possible in CP/M Plus.

Sometimes I feel sorry that I sold all this for about fifty dollars...

Freek.
