Not quite. The 88290 is only usable with the original Scanjet. The
Scanjet+ required the 88295 version. The 88290s were at one time made
available again by HP for ~$400 which reflected costs of restablishing a
short run production and handling. With what has happened to scanner
prices in recent months, it is unlikely that anyone in their right mind
would pay anything like that today.

True. The 2502 card that Phil Beesley has is probably a 53C400A based
card and is usable with Scanjet IIp, IIcx, 3c, 3p, 4c, 4p, etc.
