Extender board HF-60247 with attached modules HF-12247, HF-64115 and HF-1471
Near 2015 I robbed some 100 scrapped hotel TV cards from its HITACHI CPUs HD6433214F16 (H8/3214 family)... Exactly 85 CPUs survived this operation and it was catalogued in my CPU collection as UC-044...UC-127 and UC-290. Latter is still on original module HF-1784#85. There was even more these cards (maybe some 1000 pcs but after desoldering 100 pcs I said THANK YOU :)) ). It was a lot of work... These cards almost certainly went from demolished Hotel Rzeszów, but I have never see it myself (funny thing is that in 1990s I was on interview there to work as TV technician in Hotel Rzeszów for this system but I changed my plans because I've found another job...).
In such way HITACHI HD6433214F16 became most popular CPU in my collection and I created some test modules like HF-9021#1, HF-9021#2 and HF-12247.
Because I couldn't find good debugger for HITACHI H8/3214 I wrote it myself. It is simple DOS simulator/debugger but writing simulators takes a lot of time...
I renamed some instructions mnemonics because I also wrote my own macro compiler. Macro compilers are not so stable as dedicated compilers, so debugger is very helpfull to track errors. I also changed notation, (original HITACHI notation is reversed and have some strange stuff). Because I like AVR assembler style it is similiar to it.
H8/3214 Simulator was registered as HF-65214.
HITACHI H8/3214 SIMULATOR
In this design XTAL is mounted on UC module what is much better than placing it on extender board (less stable variant).
Extension board for this module HF-60247 is under development.
