Pascal Holdry has completed development of a revised (smaller/simpler) RS-232 interface for the Model I. Details and schematics can be found on his site at http://prof-80.fr/carte-rs232-trs-80-m1/new-rs232-m1.
Ian Mavric has modern replacement hardware for those in need of the following:
1) Model I RS-232 Cable
2) Percom Doubler for the Model I
3) Grafyx Hi-Resolution Board for every Model 4 (4, 4P, 4D)
4) Buffered Cable for the Model I Expansion Interface
5) Omikron Mapper-1 for the Model I
Of course, this is on top of the FreHD product
Those interested should reach out to Ian at IanM at TRS-80 dot com.
Richard Wyatt has been added to individuals who can repair TRS-80’s. Richard is based on Canada. For those needing TRS-80 repairs in Canada, consider emailing him. Information can be found on the TRS-80 Repairs page.
Pascal Holdry is looking for a DMK image of the CP/M made by Omikron to work on a Model III with an Omikron mapper card. If anyone has a disk with this software please contact me at contactira at trs-80 dot com.
Pete Cetinski has improved his TRS-Box so that it now works with a serial port.
TRS-Box is a Dropbox client for the TRS-80 Microcomputer. It allows you to navigate and copy files from and to your Dropbox from your TRS-80.
Trs-Box used to require a TRS-80 Model I with MISE or a TRS-80 Model III or 4 with M3SE, but Pete has gotten it to run on any floppy or hard disk enabled TRS-80 which has a RS-232 interface (although will need to buy a serial-IP adapter).
Pascal Holdry has completed development of the Percom Doubler II for the Model I. Details and schematics can be found on his site at http://www.prof-80.fr/doubleur-new-perc.
It is likely that someone (NOT ME) will be working on making the hardware available for sale in the near future for those who wish to buy it.
