Dear Friends and Customers,

A2Z80PLUS card is a 16MHZ Z80 card, but when using CP/M with a diskette, It looks no better advantage,

(Actually, in the past, there was already has a way to drive by HDD but, I can't make it run to loss of files and data)

For A2Z80PLUS, please see the posts in the link below.

However, the value of luxury goods is revealed in the end...

The drive of HDD was restored properly by the following as link.

So, I experimented/tested right away.

Insert A2Z80PLUS into slot 1,

After installing SD DISK II PLUS in slot 7, select the corresponding CP/M image and boot

First, PRODOS comes up.

To start CP/M operation

-PCPIBOOT (return)

After a while, the number selection appears. At this time, if you press '2'...

CP/M appears.

Drive is

A: B: C: D: Four are caught.

Since the FREE capacity is checked, it has enough free space as shown below.

Additionally, A clock has a driver but, I haven't been able to determine what kind it is.

From now, we can use CP/M with big spaces.

Enjoy it.

32MB PO images are here.

I searched dBase II on Internet and could get a dBase 2.4 and tested.

I recalled my old memory and made simple program to add testing records.

Now it have 45752 records and works fine.

This dBase program is general one and I transfered it to FDD and copy it to the HDD of SD DISKII plus.

To transfer the program to CP/M..

1) Download programs for CP/M

2) Add files for APPLE II image disk by Cpmtools 2.9.

It looks some complicated but works.

3) Transfer this FDD image to another SD DISKII Plus. (For conveniances I used two SD DISKII Plus)

4) Boot CP/M and Copy files.
