The Rompak cartridge is something that all Timex computer users can appreciate. It can instantly load programs, such as games or utilities, into memory. The cartridge is memory mapped in the unused 8 to 16k block of memory, and it has an expansion connector out the back, so it can be used with the T/S printer or ram pack. The heart of the Rompak board, is a 74138 IC, which is used to decode the memory for the eprom. The board will accept three types of eproms; first, the 2764-8k eprom; second, the 2732-4k eprom; and third, the 2716-2k eprom. I also found it will accept roms like the one used in the ZX80, and ZX81.
If you plan to use more than one eprom in your Rompak, then I suggest you purchase the ZIF socket, available from Rompak, because it will allow you to quickly and safely change eproms. Although, the ZIF socket is an excellent addition, it has a tendency to fall out of the on board socket. To cure this, the manufacturer should have permanently attached it to the Rompak board.
Over all, the Rompak board is well built and is an excellent buy for your money, and if you have an eprom programmer, it is even better, because you can write your favorite programs on eproms and have them instantly load with one simple command!
