It's not terribly complicated. The plastic body is cheaply available.

Subject: [Techtoolslist] EPROM Emulator Questions
John's AdCOM question got me thinking a little bit....
So I have an old Itasca Systems NoROM Eprom emulator, it is sorta a
genius little device because it is literally a small black 'Extended 32-Pin DIP'
and it only sticks up about 1.5 Inches. It has a Serial Port built in
with an RJ-12 (6/8Pin?) so the cable is lightweight. They stopped
making it in
2000 or so and I really just want to make more of them (functionally).
Some improvements would be...
1. Switch to USB + daisy chain so you can literally have dozens of
these on a PCB if really needed.
2. An improved interface for sending data to the device(s) 3. Nice in
place debugging and sniffing
Anyone interested in working on a project like this with me? I can do
the software side but Im not really there on the FPGA end. I have good
details on the packaging of the ITASCA one and I can post pics if you
want. They no longer make it or are in existence so I don't want to
duplicate it per se, just build something with core functionality in the same form factor.
Email me if interested.... jess@askey.org<mailto:jess@askey.org<mailto:jess@askey.org%3cmailto:jess@askey.org>>
