Using TWO FLASH Cards

Using TWO FLASH Cards Introduction
File Copy
Recommended Usage How to tell if the Flash Card is AMD, AMIC or INTEL? Flashstore & Software Supplied
Sharing Applications and File Areas How to Delete Applications

This document describes the benefits and the procedure to prepare your Flash Cards when using two of them in your Z88.

topIntroduction

Using multiple Flash Cards, brings major benefits. Unlike the smaller sized RAM and EPROM packs, there is no wasted space in the slots, the full 1M space is used. This allows

  • OZ 4.2, or OZ 4.3
  • RAM,
  • other applications
  • and File Area

all to be accessible in the Z88 at the same time, allowing a 3M Z88 to be a reality at last.

The latest copy of Flashstore should be used as the older Zlab v 1.6.9 does not support multiple Flash cards using the same application.

topFile Copy

Using 'Copy all Files to another File Card,' you are able to Copy all the Files from one card to another, without having to use the RAM pack. This is very useful in reclaiming the space left by deleted files. This command can either be evoked in the MENU or with <>FC. It copies files from where you are, to the other Flash card. If there are more than two, you will be asked which Flash card to copy to.

topRecommended Usage

128K RAM
At least 128K RAM pack size
1M AMD Flash EPROM 1M INTEL Flash EPROM

Here is my first recommendation on how you should use two Flash cards.

Note: Flash cards can be read in any slot.

  • Slot 1 - your RAM card at least 128K to make the Z88 an expanded machine
  • Slot 2 - an AMD Flash card (which can be written in any slot)
  • Slot 3 - any Flash card can be used.

1M AMD Flash EPROM

1M AMD Flash EPROM


Here is my second recommendation on how you should use two Flash cards using the 512K Flash / RAM card if you want to use OZ 4.2 (or OZ 4.3).

Note: AMIC or AMD Flash cards can be read and written to in any slot.

  • Slot 1 - a 512K Flash / RAM card to make the Z88 an expanded machine with a bootable copy of OZ 4.2 (or OZ 4.3)
  • Slot 2 - an AMD Flash card (which can be written in any slot)
  • Slot 3 - FREE to use with any Flash card or EPROM pack

1M AMD Flash EPROM

128K RAM
At least 128K RAM pack size

1M AMD Flash EPROM

Here is my third recommendation on how you should use two Flash cards if you want to use OZ 4.2.

Note: Flash cards can be read in any slot.

  • Slot 1 - an AMD Flash card (which can be written in any slot) with a bootable copy of OZ4.2.
  • Slot 2 - your RAM card at least 128K to make the Z88 an expanded machine
  • Slot 3 - any Flash card can be used.
    NOTE: - INTEL Flash cards can only be written in slot 3.

topHow to tell if the Flash Card is AMD, AMIC or INTEL?

Run Flashstore and compare these displays. Use SELECT CARD to change card slot,


AMIC - The top right-hand side window displays AMIC (and then the chip number)


AMD - The top right-hand side window displays AM29F (and then the chip number)


INTEL - The top right-hand side window displays I28F (and then the chip number)


INTEL - Old Flashstore application for INTEL chip only. Can be updated.

topFlashstore & Software Supplied

When you buy a Flash card it comes with Flashstore and other software so that you can use your flash card straight away. When you use two or more flash cards, you do not need two copies of Flashstore, the same program can read or write to either flash card.

topSharing Applications and File Areas

Applications and files on the same deviceJust to remind you, Flashstore allows you to have both Applications and File areas on the same device. The dividing line is determined by the total size of the Applications area in 64K blocks. These applications are in slot 2 all we need to do is to erase the application area in the second Flash card in slot 3 so that we can use the whole area for files.This is just like using the older type EPROMs again (only we can still erase the Flash cards in the Z88).

topHow to Delete Applications (in slot 3)

  • You need a copy of Garry Lancaster's Romcombiner v2.02 which is supplied with the Flash card or download it from hereRomcombiner link
  • Unzip it either on your main computer or on the Z88 (you only need 3 files)
    • RomCombiner.bas
    • RomUtil.bas
    • romcombiner.bin
  • Select BBC BASIC []B
    • Type
      • RUN "ROMCOMBINER.BAS"
    • Type
      • F - for Flash EPROM block erase
    • Type 256 - for all
    • and then 0 - to end
  • Select Flashstore []J - it will show the file area in slot 2
    • Move the cursor down one to SELECT CARD - Select '3' or move the cursor to the FLASH 1024K - NO FILE AREA card
    • Format the File area by selecting Y
  • You should now see a 1024 file area with 1024K Free
