If it helps, I have made a test adapter for the TL76. I have tested the 28-pin PLCC, but not the 44-pin. However, it should work. The board was

I did similar hacking around with three Z84C15 boards that I bought on eBay. I imagine Z182 is very similar to Z84c15. https://groups.google.com/forum/m/#!topic/retro-comp/0XO4bdqJiro

based on Z84C15 which has integrated PIO, SIO, CTC and programmable chip selects. A full-feature CP/M-ready SBC can be build with ROM/RAM/disk and a couple TTL logic. It is small enough

I received the first batch of pc boards from China, so I'll wrap up what I have on OpalJena. The board modification is complete, but not quite

of the Z84C15. Replaced the EPROM with my own diagnostic W27C512 that prints out endless string of sign-on message. It works, the power consumption is about 90mA @ 5V. I think I'

PIO. Z84C15 provides the necessary address decode so I can have paged ROM, banked RAM and compact flash interface with the addition of 2 common TTL logic. The design is simple enough
