My simple V1 booster will be discontinued after this last batch of about 20 has been built. This is the cheapest and simplest 16Mhz booster about, but with the V1.5 booster basically taking over from it and offering fast-rom support, there is no real use in keeping the V1 series in production, despite it actually being the most popular booster due to its low cost. The V1.5 probably offers better "bang for buck" with fast-tos support for not much more cost anyway.
The V2 series of booster will be taking over from the V1.5 in the new year. I also am putting together a guide to fit the V1.5 booster in the STE. So the V2 will be for the STFM and the V1.5 will be used for the STE mostly. Ultimately the V1.5 booster will likely be discontinued towards the end of next year (2016) in favour for the V3 series of boosters.
The V1.5 series may be available longer for the MEGA ST due to I have a lot of PCB's with DIP GAL's used, where only the MEGA can take the extra height. Possible the same boards can be used on the STE also. But just as a heads-up for everyone of what is planned http://www.exxoshost.co.uk/atari/last/v1booster/index.htm
So anyone who wants to grab of the last batch V1 boosters should head on over to my store and get one. http://www.exxoshost.co.uk/atari/last/store.htm
