    Belts for Mitsubishi M-2894 8 inch floppy disk drives.

    Received today thanks Chris. A lot of cleaning to do before I try and get the drive going. What sort of CP/M system do you have?

    Solid State Music (SSM) PB1 EPROM Programmer

    While working through a large quantity of Exidy Sorcerer floppies that were imaged around a decade ago I came across a file EPROM.ASM for the SSM PB1 EPROM Programmer. I haven't been able to find this file online anywhere although I was able to find a binary identical copy of the accompanying...

    State of MAME gridcomp emulation.

    If you have identified problems with any MAME emulation the most appropriate route is to sign up for an account at https://mametesters.org/ and provide comprehensive details there as to how to reproduce the problem. Constructive comments are more likely to be addressed.

    what is the best way to archive a service manual?

    You could look at https://en.wikipedia.org/wiki/Tesseract_(software) - I know people who are having some success with dot matrix fonts as well which other tools really struggle with.

    British DRI 8 inch floppy drives (Data Recording Instrument Company Limited) doco sought

    I would like to get a pair of Model 7200 DRI 8 inch floppy drives going for an Exidy Sorcerer connected via a Digitrio controller board inside their enclosure. The manufacturer is an apparently a British company called DRI or Data Recording Instrument Company Limited according to the...

    VCF East 2022 videos no longer accessible - marked as private?

    I appreciate the work that you put in to shoot all those videos. The production values were vastly better than previous years. I appreciate that you want to present the material nicely but the raw streams could still stay up even while you edit and package (sans the doco). I was happy to watch...

    Anyone really good with KiCAD PCB routing?

    I don't do this because for me it complicates board bring-up. I like to put in the minimum parts to being the power supply up, get the power LED to light for example, and once I am happy that I have reached that safe harbour add more components in stages. When components pins are used as vias...

    VCF East 2022 videos no longer accessible - marked as private?

    I am halfway through watching and can no longer access the recordings of the streams. Is this a bug or a feature?

    Amiga 2000 keyboard options

    May I ask what the hard drive model was? I am working on my A2000 as well which has a Quantum Prodrive 40S with a number of issues.

    Exidy Sorcerer disk drives

    The PCB number on the controller in the Video Disk Unit that Al Kossow had matches that in my FDS so in that sense I think the two systems were provisioned with the same board. I think we confirmed that the ROMs were the same as well. However I have a manual for a soft-sector controller board...

    Exidy Sorcerer

    Thanks for the photos Ollie. It would be a shame to risk those disks while you fault-find your drive. There is very little Sorcerer software on disk currently preserved. As these drives are 100TPI the only way to read the disks is with a working 100TPI drive. You can't archive the disks with a...

    Exidy Sorcerer

    Well there you go. I was wrong. Thanks Ollie :-) Possibly not a product ever distributed in Australia. The Sorcerer itself might be a Netherlands build because the keycap colours are inverted to compared to most machines. I'd be interested in a photo of the compliance plate on the back of the...

    Exidy Sorcerer disk drives

    The OP's photo is of a blue-cased Micropolis drive typically associated with the hard-sector S-100 system. In that context what makes the drive an "add-on" is that it doesn't come with the S-100 controller card, manual and CP/M on disk, but once you have those things you can add-on the...

    Exidy Sorcerer disk drives

    The expansion units also have their own linear power supply but otherwise all correct 🥰

    U.K. Aculab Floppy Tape (similar to the U.S.A. Exatron Stringy Floppy),

    Thankyou for that resource Dusty. Does the Aculab use the same drive mechanism and/or electronics but with different host software and/or firmware in the drive and/or in the TRS-80?
