dBASE II on A2Z80Plus

◆ Z80 Card / 2021. 3. 30. 10:10

I searched dBase II on Internet and could get a dBase 2.4 and I tested on CP/M HDD image.

 

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

Now it have 45752 records and works fine but, slow.

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.

cpmarchives.classiccmp.org/cpm/mirrors/www.cpm8680.com/cpmtools/index.htm

 

Cpmtools 2.9 Executables for Windows Users

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.

PIP C:=E:*.*

 

 

Thanks

 

PS: Maximum records on dBASE II, It looks 6553x records (16bits).

If over this records, dBASE doesn't handle properly.

Anyway, This is one of example it has 65000 records and sized 3.1MB and index file sized 1.3MB. I didn't expected it could handle this size of database. :)

Here is bootable 32MB HDD image with dBASE II (in A:)

nzcm32mb.zip
2.77MB

* SD DISKII Plus need to installed on SLOT#7 and A2Z80Plus was in SLOT#4.

* And to start CP/M, need to press '2'

 

Thanks for reading.
