-
- 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.
