I have designed with the first PICS back in the very early 1990s and at the same time the 808x derivatives. I am puzzled that anyone would want to still use the 8088, because it has zero peripherals. It requires external RAM/EPROM as well. All of these things are included inside the PIC. If you want to really use the 8088, NEC made the V20, which is a clone. Also, Intel made the 80188, which is an 8088 core, with I/O ports on chip, but you still need external RAM/EPROM.
So may I suggest using the PIC, or maybe even a 68HC11/HC12 from Morotola. If you still want to use the 8088, post reasons why, and I would be glad to help.
