From an imperfectly remembered article in Popular Computing Weekly. As already shown earlier in this thread!
Probably you read about it in some German magazine? And this magazine write the wrong PW360 name?
I have made a design for a Test-Unit-II, that is completely compatible to the Hypertone-Test-Gear, as far as the pcb-tests in the cartridges are concerned. Attached you'll receive the circuit diagrams and my board-design of 1992. You need cables to connect the test-unit to an ENTERPRISE, but apart from that it should work like the original I/O-Unit of the Hypertone.
I really cannot remember who used PW320 for the machine for the first time, but the handwriting in the code-book is mine EC320 memory/rom-mappingApart from the internal 64k from segments FF-FC there is the 256k memory expansion on segments EF-E0. On the full prototype (incl. housing) EXOS is on segment 00/01, BASIC is on segment 04 and EXDOS on segment 05. Attached the ROM-Files from the prototype.
As promised I have scanned the ISSUE 6 films (component/solder/placeplan) as 400dpi TIF-Files
This version of the Expansion Unit requires the proper operation of the connected card signal /EXP.EXDOS supports this signal, but, for example, ZX Spectrum Emulator is not.
Zozo, could the Microteam work "as is" with that official Expansion Unit if the connector is unwelded?
An original 64k-internal-memory expansion ex works Elec&Eltek. There is a missing IC (U111). At that time, some components were not obtainable in far east and the memory expansions have been produced without them. The missing components had to be soldered to the pcb's during the assembly process at GRI later.
And there is an early version of the MIDI-cartridge together with an original disk from Vilmos, carrying the Scoretrack ROM-File and some demonstration songs. The cartridge pcb is the same as in my complete cartridge. But instead of the eprom there is a static 62256 ram, an additional TTL chip and a switch. The switch is for the /WE-pin of the ram (you can "write-protect" the ram) and the red wire to pin 1 is for A14. I have not tested this cartridge (I do not have the software for moving a rom-file to this ram), but I think it should be fine. At least we know now, that the one circuit is a 74S133.
Enterprise FischertechnikOne of our guys from the office was very fond of Fischertechnik at that time and he had this very expensive robotic interface and the 3-axis robot-arm. He had written some very interesting software for this device in Turbo Pascal and asked me, whether he should try porting it to the Enterprise (that was in 1993). The robotic interface had a centronics parallel interface and therefore connecting it to the Enterprise was very easy. However the existing pascal programs had to be reduced to very elementary functionality due to the limited processing power of the EC under IS-DOS/Turbo Pascal. But at least the TEACH.COM-program has a teach-in mode with way-points for all motors of the robot, a facility to save and load the trained programs and a "player" for running the programs once/continuously. You can see the robot in action on the attached photos. The source-codes of TEACH.COM are not existing anymore (at least I coudn't find them in my backups yet).
