Checked my LPT1 and with LPT_TEST it reported that the Bi-Directional FAILED. So I have to assume the Racore/Rapport add-on's did not come with BiDirection LPT's I did manage to get the ZIP 100 drive working, it was pretty easy. only needed two items Device = jrconfig.sys /d3 ( the /d3 indicates the...

is the Parallel port on these expansion units BiDirectional?

If not has anyone done a MOD for them ?

I also recently revived my old Compaq Presario I too tried to get the 5.25 drive to work, while it sees the drive, it will not read any disks..

UPDATE: Repaired the PS, just a few bad components...replaced all small caps , works well also put heatsink compound under the switching transistors to allow better heat transfer. seems to run very cool...

So I have no idea how this is suppose to work. Looks very similiar to the Racore addo...
