A 32 KB Tektronix 4052 CPU / Logic board assembly has appeared on eBay. https://www.ebay.com/itm/156073396294

Congratulations! That is a very nice find. You said you had the documentation, I found the Stuttgart site some time ago that you mention above and they had posted the ROM dumps. Two computer magazines ran articles on the prototyping boards, these are: Kilobaud October November, and...

Monty: Thanks, I had seen the CALL "EXEC" document before, and I was hoping that additional details on the 4054 assembly language calls and data types would shed some light on how parameters are passed in the 4051 version. When I invoke CALL "DEBUG" on a 4051 emulation, I see some...

Monty: I was reading the 4052 Assembler documentation you posted to GitHub, and was intrigued by the details of the stack parameters discussed on Page 3 for the EXEC call. This level of information is not found in the 4051 Assembler document, but from my inspections of memory using...

Monty: Thanks, that was what I needed. In effect, I am "building" a tape in the storage popup window by importing individual program files, assigning them a unique file number, and saving the bundle to the emulator's "tape drive." At that point, on exiting the storage popup, I can load the...

Monty: Returning to WaveyDipole's emulator with storage, I have been able to follow the Get Started steps for the 4051 Emulator procedure above to load the Games.Tape, however, I have been unable to discover the process to load and run a Single File. I can Select the file and see it in...

Monty: I noticed that the [MMMM];J (Jump) command seems to work in most 4051 emulations that load DEBUG through the EXEC function, but not in in Falter's version of the 4051 Emulator with Board Bucket DDT. I want to look more closely into the disassembly, but I was also looking for...

Robertcx: I noticed that you have a copy of the Motorola Exorciser Users Guide (1975) in your archive. There is a cleaner copy up on Archive.org located here: https://archive.org/details/bitsavers_motorola68ORciserUsersGuideSecondEdition1975_12224448 The M6800...

Monty: I am intrigued by WaveyDipole's emulator with web-storage, but I have not been able to repeat the steps as indicated. So far, I can get to the point where I can locate and select the Games.tape file, but I never see the "restore complete" pop-up. Trying this in...
