• * * * * A1000/A500 86-pin to 100-pin Expansion * * * **

This HACK will allow an Amiga 1000 or 500 to use it's 86-pin expansion 
      connector as an A2000 100-pin slot!!!!!

Parts Needed:
	1  100-pin edge connector (Female)
	1  86-pin  edge connector (Female)
	1  74LS86 TTL gate
	Ribbon Cable

PLEASE Refer to included picture for building details:

      Try to keep the cable length a short as possible,
longer cables tend to have noise problems. If used on
a 1000 the PAL's should be grounded to help prevent
noise problems.

Also there may not be enough reserve power to run these
cards on a stock A500 power supply.  Although I've had
it working on a stock A500 with a GVP card ( 40Q + 2Meg)

	The following products have been used successfully:

	Commodore A2091 w/40Q+2M
	GVP Series I w/40Q+2M  and w/105Q+2M
	GVP Series II w/40Q+8M
	SupraRam  w/8M
	Supra-zi Modems

The GVP Series II is very susceptible to bus noise
(probably because of the incrediable transfer rates it
achieves). My original cable was about 7 inches, it worked 
with all of the listed products except the Series II.  Making
the cable shorter proved to be the answer.

I've had this cable running for about 5 months on my 
Amiga 1000 with a Spirit 1.5M Ram expansion and a 
Commodore 2091 SCSI Controller (w/40M Quantum drive)

If you find this usefull a ShareWare fee of $20 will
be greatly appreciated. 

Since I have found it somewhat difficult to find the
86-pin and 100-pin edge connectors.  I have put together
a Kit with all parts and instructions. This kit is 
available with ShareWare Registration for $45+Shipping.

If you have any additional questions or information.
Please contact me at.
