	The files in this archive are a dump of the SPLD device on the Data I/O Mass Storage Module option, as used on the 2900, 39xx, and Unisite series device programmers. The MSM's hard drive is a simple 44-pin PATA interface, similar to that used in many pre-SATA laptops.

	The two files in this archive are identical except for the JEDEC format used to store them. The file ending in 002.jed is stored in JEDEC Full format (Data I/O #91). The file ending in jedk.jed is stored in JEDEC kernel (Data I/O #92).

	In either case, the file came out of an Atmel AT22V10L-25JI PLD in a 28-pin PLCC package. This particular part is no longer readily available. The current replacement seems to be the ATF22V10C-10JU. This is still a 5V part, but is much faster, having a maximum clock rate of 125MHz or so. I see no reason why it would not work in the circuit, but as of the date of this file I have not tried it.

	As of the date of this file, I have completed the prototype design for a duplicate of the MSM, using a CF card instead of the hard-to-find miniature hard drive of Data I/O's original design. I have also performed 'proof-of-concept' experiments on one of my own MSM's, and have determined its disk interface will work quite well with a standard CF card.

	Once work on this design is completed, I will make all the details public. Anyone with the necessary skill will be able, for the first time, to build an MSM for their own programmer(s).

	Happy tweaking.
