Hello,
For those of you who are familiar with the Serial Pro card from Applied Engineering, it is basically a SSC compatiable card with a real-time clock built in. This card has some ROM on board that looks to be an EPROM.
Does anyone know if this ROM has been dumped already? If not, I might be inclined to buy a reader/writer and do it myself.

Assuming that it's loaded with a 6502 program, I'd be a bit surprised if you couldn't find a way to dump the ROM contents directly from an Apple II that it is plugged into. The I/O memory space is 2k, so if there is a larger ROM on board, you would have find a way to page through it.

Thanks for the link to the .bin
I'll check my version when I get back later.

You can use the monitor to relocate the ROM image from $C800-$Cfff down to somewhere like $2000 and then BSAVE it to disk.
I know this is a bit of a necro, but I just recently aquired an AE Serial Pro. ROM images don't seem to be existent anywhere (even the above link for v1.4 is dead). So I dumped my v2.0 using my backbit chiptester. If it matters, the EEPROM ins a AM27C64.
On a sidenote, whats the best way to replace the presumably dead nicad pack on this? I haven't actually tried the card out yet, and probably won't have a chance for a little bit.
Varta still makes this 'Mempac' style of rechargeable battery. Even though the cells are NiMH instead of NiCd, they promote them as being trickle-charge compatible as a result of a special electrode design.
See Varta 55615-703-012 (the last six digits match the old NiCd pack on the Serial Pro)
The old pack may or may not be dead. Usually what causes NiCd cells to die are dendrites that puncture the separator and form a short circuit between the electrodes. There are plenty of ideas online of ways to "zap" the dendrites using high voltages (obviously it must be done out of circuit)
Oh, nice. Thanks for the tip on the NiMH varta packs.
You can make a poor-man's version of this card by installing a Dallas No-Slot-Clock (with a couple of pin modifications described in the manual) underneath the ROM chip of the Super Serial card. Works beautifully.
As mentioned in my troubleshooting thread, here is the 1.4v ROM dump form the 2nd card I picked up. If anyone is curious and smart enough to decompile and look through the differences, I'd be interested in hearing them.
Also, not sure if it's useful, but I dumped the PAL as well. On the v1.4 ROM card, the PAL was stamped SP1A. But on the 2.0 ROM card, it was stamped SP1A-Q. But the resulting dumps of both using my backbit seem to be identical. I have no idea if they are of use, but here they both are as well (even though they seem identical).
