This card has been developped by Roger Schaefer (USA) A http://www.rasmicro.com/
It is described in details in the project page A http://www.rasmicro.com/projects.htm ; the difference between Version 1 and Version 4 is that in Version 4 there is the place to connect the SUB-D 9 connector for the serial connexion.

This card is useful to developp little applications with a MC68HC811E2 for example or a MC68HC711E9;
The MC68HC811E2 contains 2Kb of reprogrammable EEPROM :
while the MC68HC711E9 contains bigger eprom (12Kb) but is OTP (One time Programmable) :
It contains a little prototyping area with almost all interesting lines of the microcontroller.
It includes a connexion to a 2x40 Characters LCD Display and a connexion to a P.C. keyboard (PS/2 Mini-Din) connector..
With such a card you can program and read MC68HC11 devices by using the freeware
software HCLOAD available here
A http://web.archive.org/web/20100226192638/http://www.microsyl.com/hcload/hcload.html by connecting it to the serial line of a P.C.
Application I have done with this card :
* Radio Data System (R.D.S.) information display and time display by using the TDA7330 (ST) chip and a little fm radio based on the TA2003P (Toshiba) chip [RC 601 radio receiver]
