CRT Controller Handbook (1980)
For Info:
I recently (re)discovered I'd got a original copy of this book - Which states it can be used to update Section H of "An Introduction to Microcomputers - Volume 3 Some Real Support Devices" (Osbourne/McGraw-Hill 1978) (Which it seems I've only picked-up the Volume 0 "The Beginner's Book" of, so far) It only covers five main devices, with these three being rather obscure: - Nat. Semi DP8350 (has mask-programmed options), - Intel 8275 - SMC 5027 / Texas 9927. But it does have a chapter on the more-common 6845 (Although only original non-enhanced 6845 without extra suffixes). Plus, most interestingly, a chapter on the 6545 version of the 6845 - where they cover the (few) differences from the more usually used 6845 (It seems you can have a non-continuous E-Clk, for easier use on non-68xx/65xx systems without that) So I thought this may be of interest to those with the CRTC versions of the CBM/PET, as I recall this recently being discussed on the one ScottishColin had recently acquired and now got working. I found a copy of this book is viewable / a 33MB download here: https://ia601003.us.archive.org/28/i...r_handbook.pdf (But I'm not seen if there was ever an updated version of it, that covered any other CRTC's) Last edited by ortek_service; 3rd Dec 2023 at 8:45 pm. |
