New run of GIDE interface...

Hi all,

Who would be interested in a group for a new GIDE kit ?

GIDE is IDE drive for Z80 !

The GIDE interface has been developed (originally by Tilmann Reh in
1995) to enable Z80 computers to connect to IDE devices. Although the
IDE bus is a 16-bit data bus the GIDE interface reads and writes in two
8-bit accesses.

If there are people interested, I can start the making of 10 complete kits !

Like this : <http://www.iee.et.tu-dresden.de/~kc-club/gide/gide6.html>

After is possible to connected an IDE to Compact Flash adapter !

The Compact Flash in IDE mode works out really well with CP/M 2.2 since
the maximum disk size that this OS can handle is 8MB. All of the CF
cards that I have looked at have 32 sectors per track and allow 512
bytes per sector (= 16K per track) and they have just under 500
Cylinders per head. This gives a total size of just under 8MB per head
and the number of heads depends on the size of the CF. (in this case
16heads x 8=128MB)

Regards,

JB

Sounds great!

I'd like one.

What would be the cost?

I'm interested, but would like some idea of the cost (shipped to US) before
committing.

Hi
I am definitely interested . I have been looking for a GIDE for a
long time. As the original site that did them said they would do any
more.I have a working Z80 system ( INTERAK ) like Alan Paton's and I
am just on the verge of getting CP/M 2.2 on to it.

Yes, I am interested!

If you want just to connect a Comact Flash card, why use the GIDE
design? The Z80 is 8 bit, and so is Compact Flash. So why do should you
want a 16-bit interface in between?

Just want to mention if anybody out there would like to run an IDE
interface on an S-100 bus Z80/8086 etc. system please take a look at
the Dual IDE S-100 board described here:-

http://s100computers.com/My%20System%20Pages/IDE%20Board/My%20IDE%20Card.htm

Also they might find the software links useful for drivers/monitor
etc. for CPM3, CPM86 and MS-DOS.

Why GIDE and Compact Flash card ?

Because it works and is reliable on the Kaypro

Very nice for S-100 Bus machine, but for others ?

work in progress ;)

I try to have very good prices...

Probably with an PCB made in china.

Yes, I'm also interested.

Perhaps in 2-3 kits whilst I can get them.

Any idea of cost as yet?

Anyone tried one of these with a Bondwell 2 laptop?
