V3.11test Object files for BETA release:

Updated 1/22/2007


Object files (in Motorola S19 ASCII format) for U3 and U4 EPROMs on the FF-800.

Disclaimer: I have tested each new function code to make sure that they have all been translated correctly. However, I have NOT tried every aspect of these functions, so it is still possible that some feature, or combination of features, might cause your system to lock-up. While I feel this is unlikely, you should be aware of the potential risks and be willing to accept them for this beta release.

NOTE: The "checksum error" that is displayed after some of the following programming operations is expected and can be ignored.

Expanded U5 device is NOT required to run V3.xx. Features that require expanded U5 are disabled until you install the new memory.

NOTE: The FACT.S19 upload is only required if have an expanded U5 RAM.

If you install the U5 upgrade later, follow the instructions below.

Instructions for NON-FFLASH Users:

You will need to obtain a 128Kx8 EPROM (511-M27C1001-12F from Mouser Electronics). The EPROM data files are in Motorola S-Record (S19) format. Most device programmers have a unique command structure, you should consult your programmer's documentation to perform the following:

U5 Expanded Memory Upgrade

If you wish to obtain an expansion memory chip for U5, contact Component Distributors at 800-848-4234. This is their Plano, TX office, so don't be disturbed if they give you another number to call. The device is a SIMTEK 32K x 8 NVRAM, part# STK11C88-45P. The "-xxP" suffix indicates the access time (i.e., 45ns) while the P indicates narrow plastic DIP. There are a variety of speeds that will work, -35P, -25P or -15P. Basically, whatever they have in stock should work. Also, industrial parts (-45PI) will also work. The cost should be less than $15 plus shipping. If you have any difficulties obtaining this part, let me know.

Be Sure to note the orientation of the existing U5 before replacing it with the new device. The SIMTEK parts are half-wide, so the U5 socket actually consists of three rows of equally spaced socket pins. This arrangement allows a normal width part to be used in place of the narrow SIMTEK part. The SIMTEK device should be installed so that it occupies the two socket rows closest to U4.

After installing the new device, you should perform a factory initialization sequence as described below.
