Hi, some of the Atari ST fans are also 8-Bit fans (and vice versa) and may already know, that I make some little projects to enhance the capatibilities of the Atari 8-Bit family. Some time ago I´ve decided to do the next step and make some stuff for the Atari ST series, too. Find some infos here. PLEASE READ THIS FIRST: All informations (availibity, pricing, links to manuals etc.pp.) is found in my info file - see also link in my signature. This file is updated 2-3 times a month constantly, so bookmark it 🙂 PLEASE don´t ask for prices and availibity here in this thread. See 1.) You don´t need to show interest (what is very nice, indeed). All projects are finished and will be offered independent from request here. See 1.) The first batches of all five shown expansions are ready at mid to end of July 2020. See 1.) Thanks for reading 🙂 Now here´s brief overview... DUAL-TOS Card for Atari ST computers (TOS 1.0x / 2.0x) This expansion can be installed in all Atari ST (except 1040 ST with CPU under the disk drive) and the Mega ST. It enables the usage of any TOS 1.0x version and TOS 2.05 or 2.06. No need to dril holes for switches, just use the existing RESET pushbutton. Eraseable EPROM included, if wanted, preprogrammed with the TOS versions and language of your choice. --- DUAL-TOS Card with Mega ST compatible RTC for Atari ST computers (TOS 1.0x / 2.0x) This expansion can be installed in all Atari ST - except 1040 ST with CPU under the disk drive. For this special version of the 1040 ST a seperate version will offered in the next 3-4 months. The DUAL-TOS Card enables the usage of any TOS 1.0x version and TOS 2.05 or 2.06. No need to dril holes for switches, just use the existing RESET pushbutton. Eraseable EPROM included, if wanted, preprogrammed with the TOS versions and language of your choice. This version has also the Ricoh RTC chip onboard, which is fully compatible to the Mega ST RTC. You don´t need special software, all TOS versions from 1.02 up to 2.06 supports this RTC. Just use the Control Panel to set the clock. --- DUAL-TOS Card with Mega ST compatible RTC for the Atari 1040 STE computer (TOS 1.06 / 1.62 / 2.0x) This expansion is specially made for the Atari 1040 STE only. It´s the first (known to me) expansion which enables a Mega ST compatible RTC for the 1040 STE. Also it enables the usage of two TOS versions which are able to run on an Atari 1040 STE (TOS 1.06, 1.62 and the 2.0x). No need to dril holes for switches, just use the existing RESET pushbutton. One-Time-Programmable PROM included, if wanted, preprogrammed with the TOS versions and language of your choice. You don´t need special software, all TOS versions running on the 1040 STE supports this RTC. Just use the Control Panel to set the clock. --- HD Module for 1.44 HD disk drive for all Atari STs and the 1040 STE This is one of the smallest PCBs with fully automated HD features for the ST series. It supports two drives with different setups (HD/HD, DD/HD, HD/DD, DD/DD), generates automatically the 3 ms step rate pulse and corrects the media change detection problem with standard PC disk drives. It has it´s own clock onboard, so no disturbation to the weak 16 MHz signal from the Shifter occours. You need a HD compatible disk drive which mostly must modified to work with an Atari ST (drive must be set to DS0 and HD-output on pin 2). --- 4 MByte Memory Expansion for all Atari ST and the Mega ST This PCB enables to expand your ST´s memory to 4 MByte. It can be installed in all Atari 260/520/1040 ST/STF/STM/STFM and the Mega ST series. It uses two banks with 2 MByte each, if wanted, only the first bank could be used and the 2nd bank deactivated. --- Reminder: All informations (availibity, pricing, links to manuals etc.pp.) is found in my info file - see also link in my signature.
