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.
