Pentagon's higher speed mode

IIRC, Pentagon itself was just a 128 clone, running at the usual speed. However, the Scorpion model, based on Pentagon, was able to run at higher speed. My memories are vague here, I thought it was twice the original (7 MHz not 5), but I only got it as rumours from my friends who have seen it working, not from an actual benchmark result and never from somebody who knew the insides. See This page (in English!) for a supporting claim. I will try e-mailing my old friends (from the Hobbit (computer) glorious gang) and see what they remember.

That would be great if you could get this detail resolved, thanks :) MasterDirk 09:33, 8 Sep 2004 (UTC)

Pentagon (original 1989 square motherboard) was a 48 clone, with no WAITs. It has not any turbo mode. I have two Pentagon 48 motherboards, 2 Pentagon 128 (Pentagon +) computers (working, but unstable), and one Pentagon 1024SL v2.1 (working, stable). Alone Coder 20:22, 8 September 2007 (UTC)[reply]

Pentagon 2

The Pentagon 2 mobo clearly shows a copyright date of 2006, along with many chips almost certainly unavailable in the СССР (e.g. the Altera FPGA.) I think it's somewhat misleading to refer in the main text to the reengineered Pentagons as 'the latest versions' when they're much more of a retrocomputing effort AFAICT. --moof 20:25, 15 July 2007 (UTC)[reply]

Pentagon 2 never existed. There was Pentagon 2+ (1991). The model you pointing at (with FPGA) is Pentagon 1024SL v2.x, developed by Alexey Zhabin (King of Evil) in 2006. It is still in production. Previous Pentagons had not FPGAs, not counting small ULA in Pentagon 3+ (1993, Solon). Alone Coder 20:22, 8 September 2007 (UTC)[reply]

Pentagon 1024SL v2.x continues general Pentagon line, including ideas of devices suggested by numerous people in 1996-2005 (1M memory, Mr Gluk Reset Service, video modes), these devices were originally soldered to Pentagon + motherboard). Alone Coder 20:26, 8 September 2007 (UTC)[reply]
