Good memory! The D2 kit was indeed more hobbyist friendly including all the necessary logic as well as discrete parts. Documentation was also more complete with app note encouraging modifications and “hacking”. Many hours of learning and fun. Here’s a photo of an unbuilt kit.
There was also a related (similar looking) board called the MES6800 Exorciser Evaluation Board which had mostly the same layout as the 6800D1/6800C PCB but included address/data bus buffers. The MES6800 is actually what is pictured in the thick M6800 Applications Manual and not the 6800D1 (no...
The 6800D1 was one of the first Motorola dev kits I used. Followed by the 6800D2 then Exorciser Development systems. The D1 binder contained a card with the key Motorola chip set and bare PCB. Along with assembly instructions, mikbug listing, and schematic. Builders had to supply the other...
MIKUL boards were developed for, and utilized in, a wide variety of industrial applications by TL Industries Inc., Northwood Ohio.
I've scanned the TL Industries Inc. MIKUL manuals I have:
MIKUL 6809-2 Monocard Microcomputer...
Depends on the video display controller used. My early swtpc video board (percom electric window) uses the CRT5027 controller, and my similar mid 70s Motorola Exorciser system video boards use the 6845 controller. Both video display controllers use memory mapped display memory and incorporate...
Found this correction for the syn routines in a user note article from: http://retro.hansotten.nl/uploads/books/Best_of_Micro_The_Volume_2_1979_COMPUTERIST_The_US.pdf
That rings a bell, several years ago I asked and paid that seller to scan his manuals for me, as the S-100 ALT-2480 circuitry is nearly identical (except for the bus interface)
to the Motorola Exorciser versions of the 2480 I have - EXO-2480, and EXO-512.
Here are the PDFs he sent me of the...
Thanks for additional title, I've collected a fair number of 6800/68XX books over the years (decades) and hadn't seen this one before utilizing the D5 for examples.
The book "Introduction to 6800/6802 Microprocessor Systems" by RJ Simpson and TJ Terrell pairs nicely with the 6802D5 trainer.
Besides basic intro to concepts, it has nice worked examples and labs utilizing the D5 trainer.
Shows up cheaply occasionally in used bookshops / ebay. Also available...
There were also early (spring 1976) machines that tried to be "hybrids" between hex display/keyboard systems like the MEK6800D2 and full up systems using a terminal or CRT for display.
My second computer after a MEK6800D2 was the Digital Electronics Corp DE68.
A 6800 computer that included a...
Hi @Wulfman,
Welcome to the forums.
I’m the lucky Motorola enthusiast who acquired the exorciser, wintek, and related vintage equipment from Vincente awhile back. I still have the em189 and associated binder of manuals. The exorciser and wintek systems are a blast to use, I’m developing on...
