https://github.com/rcl9/How_To_Archive_O..._Tapetool2

This tutorial captures my experience with retrieving and archiving early 1980's Exidy Sorcerer data tapes and directly converting them to binary, Exidy Sorcerer .tape format and related de-blocked text files using the TapeTool2 utility program. If I had access to this repo before starting my project then it would have saved me a good day or two of head banging and head scratching. It also applies to some other computers supported by Tapetool2.

However, much more importantly for an Exidy Sorcerer user (or other retro-computer enthusiasts) reading this tutorial, I provide a well defined batch script file named "convert.bat" which will quickly convert a 300 or 1200 baud .wav file into a corresponding binary (for CP/M usage) and .tape file (for jSorcerer or MAME usage). Other sites on the Internet often provide dozens of 1980s software downloads in .wav audio file format but no simple method to convert them into runnable files for the Sorcerer.]]>

This is a significant historical posting in the world of retro-computing. Over the last 40 years I have not seen any hand's-on tear downs or reverse engineering of the super-rare Exidy Multi-Net 80 "User Module" S-100 card nor one which has been hacked and repurposed as a stand-alone MIDI processor board (as I have done herein).

I decided to reverse engineer the board on November 17 and 18 1984, write a new monitor system for it, then eventually develop a daughter card to give it RS-232 and MIDI capabilities. This repository documents those endeavors for the current and future benefit of the retro-computing community.]]>

This retro-computing article strives to provide a historical snapshot, archive and description of the short lived Cypher Z80/68000 single board computer which was designed, built and sold by Motel Computers of Willowdale Ontario in the 1984-86 era. It was believed at the time that CP/M-based computers would (ideally) remain the dominant operating system well into the early to mid 1980s. The Cypher SBC arrived in the 1983-1984 era when CP/M-68k and 68000 CPUs were becoming more readily available. What the designers of the Cypher computer did not foresee was the rise and dominance of the IBM PC, DOS and 8086 processors which would have been a prime reason that the company disbanded the project in 1986. Tech manuals, schematics, historical advertisements and a history of Motel Computers is provided.

Implementations for 8080/Z80 and PDP8 are provided as well as raw data for 'Daisy Bell'. Unless you were a business user who could afford a very expensive S-100 system running CP/M on 1 or 2 floppy drives then there wasn't very much that a "home accessible computer" could do other than (drum roll please!) play computer music.

I forced myself to pen the following tutorial as a prerequisite to two other retro-computing tutorials that I just finished up which reference MAME on the Sorcerer. 

How to Set up the MAME Emulator for the Exidy Sorcerer Running Dreamdisk CP/M 2.2
https://github.com/rcl9/How-to-Set-Up-th...amdisk-CPM

My tutorial also explains my method of automatically generating a .mfi disk image from a directory of PC file, including some info about how to get those files back to a PC from the CP/M disk image. The latter part provides some info about using MAME with the Exidy (Micropolis) Floppy Disk System.

In February I had reached out to Milan Hudecek as a means to connect up with Richard Collett, Mike Thompson or Rick Millicer who had worked on this Dreamdisk CBIOS for the Sorcerer. The source code implies that there was a CP/M 3 port in 1987 which interested me given that there is no command line recall in CP/M 2.2. However, Rick never did respond to me after getting my indirect message via Milan.]]>

So replaced the power supply large 22,000uF cap with a 35v 105oC one (original was 16v and 80oC) but with the connectors on the one end.  I connected the + terminal okay but run a wire around to the -'ve pcb connection and used hot melt to keep it all in place.  Replaced the 2 large IN5408 diodes, appears they had been previously replaced but soldering was crap with the solder pads lifted off the PCB.  Its a wonder it worked before.  I also replaced the grey 240v power lead with another grey power lead so it doesnt react with plastic case.  Put it back together after checking the power supply voltages. Then connected a monitor, turned it on and bingo, stable as a rock.  Stayed that way for 15 min. as it would be wavy right from the start in the past.  A good afternoon job I've been putting off.]]>

I am a now retired electrical engineer who graduated just as these new fangled microprocessors appeared (in fact my work experience with Telstra for my degree was to select the preferred processor to be used for ongoing projects with Telecom Research Labs - I chose the Motorola 6800, but what would a graduate student know anyway !)

So i ordered a SYM-1 system whilst I was assigned to the Pilbara in 1979, and after an extraordinary amount of effort I managed to program it to be a clock - this was after upgrading the main RAM from 1kByte to 4 kByte (luxury!)

Returning back to Melbourne in 1980 or so, I found the ETI articles about the DG680 CPU card, and ordered the kit from Applied Technology, along with a DG640 Video card. And again after much effort I got them up and running using a modified cassette recorder (the one I had used on the SYM-1) for program storage

I then took out a personal loan (really) and purchased a S100 FDC from Morrow Designs along with a double density double sided 8 inch disk drive, stuffed all the cards into a homebrew chassis with an S100 backplane, and got CP/M up and running. And a great big thanks to whoever was handling purchasing in Applied Technology at that time, as they not only supplied the CP/M software they also patched the BIOS to run on the DG680 CPU and DG640 VDU. And they told me about a required chip replacement to make the interrupts work with the Morrow controller and the DG680 CPU

Somewhere along this journey I bought a 64k Dynamic Memory card (the 1st 16K cost around $350, the second 16K cost around $80 and the third 16K cost $16. Ah the power of mass production

I also stumbled into a group of hobbyists who also has S100 systems based on the DG680 card. We used to meet in one members house near Greensborough - there was less than 10 of us as I remember

That group morphed into the Melbourne MicroBee Users Group in Burwood after Applied Technology - I dropped out after we got over 70 people turn up to the "expressions of interest" meeting..... The first "official" meeting of the Melbourne chapter has over 250 people turn up!!!

Getting back to my S100 system. I was getting more and more frustrated with the 64x16 screen size of the DG640 VDU card, along with the "flashes" on screen whenever the CPU access the video memory. And being a poor graduate engineer I could not afford a better 80x24 card (one personal loan for my computer has been enough)

So I decided to build my own (ah the naivety of youth)

I ended up designing and prototyping a 80x24 video with an onboard Z80 CPU running in lockstep with the 6845 CRT chip. all accessed through a parallel I/O interface so as to not use up precious RAM space. The onboard Z80 allowed the video card to emulate different terminals/screens just by downloading new firmware into the VDU card. Over time I added bit mapped graphics (640x480), colour (16) and various emulations

I showed the prototype to the guys at the at the club, and several of them expressed interest in building their own version, so I got a card artwork done and had a production run of around 6 cards. These were duely delivered to the guys at the club just before it morphed to the MicroBee User Group

The card was eventually was called the "ByteWyde Systems BWS-2010 VDU

I've attached photo's of the original prototype, and the production board for your entertainment. As for the card, it got migrated to the STD buss form factor and got used in a lot of control systems in the mid to late 1980's - ByteWyde systems was my company along with my elder brother that specialized in the control system space

So after all of that, I am curious whether any of the other boards made ever got built and installed in anyone's system. If you have ever heard of this card, or even have one of the cards, i'd love to have a chat some time about thost days - it certainly was an exciting period in the computer world!

My apologies for the long post - this has obviously been bottled up inside for some time !!!

I have a working Electronics Australia 2650 processor board (well I own an original 1978 board on the shelf, and use the IC's in my 2024 reproduction board).

The repository files from the Games Tapes 1 - 4 contain wav and pgm files.
WAV I understand are to be played via a cassette interface.
What are the PGM files used with as they do not appear to be in the 2650 Absolute Object Format described in SS51?
Is there a way to convert PGM to 2650 Object format?

I have other 2650 files in HEX or TXT files that work OK via PIPBUG "L" command.

Thanks

I'm curious about whether anyone here has a BBC micro? Particularly anyone in Brisbane.
Back in the early eighties, I bought a Bee, and my brother bought a Beeb.

He later gave me his Model B, which after recapping the power supply, I am going to test.
It's a cassette based system, and has a small amount of software, including a game I can't wait to try called "Time Trek", a Dr. Who text based adventure game.
I am also keen on getting hold of a Spitfire simulator that was available. I think the one I'm remembering was "1942".

I remember one of the Demo programs was a poem by Roger McGough called "Just Hit Return", which generated a new line every time you hit "return".]]>
I'm curious about whether anyone here has a BBC micro? Particularly anyone in Brisbane.
