Hello. It's been a while since I've used a Chipmunk Drive. But I do have some information. Most of it can be found via https://1drv.ms/u/s!AgRHXuUu57CegkMLB-xmRYPklMQR?e=crP28r
1. For best results, the Chipmunk drive should have a power supply with at least 1.5 amps. The power supply normally used with a M100 unit does not have enough amps. 2. These units are virtually indestructible. The weak points being the pins on the adapter card going to the M100, and the ancient ni-cad battery. 3. As I recall, the operating system is actually on an eprom in the unit, not on a disk. ________________________________ From: M100 <m100-boun...@lists.bitchin100.com> on behalf of Greg Swallow <gswal...@mchsi.com> Sent: Monday, February 28, 2022 3:52 AM To: m...@bitchin100.com <m...@bitchin100.com> Subject: [M100] Chipmunk Drive Utility Disk (img) All, Ok, Chipmunk from eBay now attached to M100 w/ PCSG ROM Bank and the Chipmunk PCB & cable that was included w/ the ROM Bank. Got an adjustable/universal power brick that seems to be doing the trick power wise; i.e. red light blinking & diskette inserts/pops out ok. Looks like it needs the CDOS diskette to load CDOS to RAM. Have checked Club100.org and don't find anything there. Is there an image (360k on 3.5") that can be written to a 720k dislette? Or, anyone have a Chipmunk and willing to send off a copy of the diskette, please? God bless, GregS <>< Feb 25, 2022 4:24:04 PM Stephen Adolph <twospru...@gmail.com>: So, I burned a ROM and tried it in my T102 (which is socketed). Interesting results. It works. But, visually it is a bit off. Due to the hardware scrolling, you get wrap around of lines the moment you program the drivers to scroll. Expected. However, sometimes that means you get a flash of characters where there should be none. This is a bit annoying. So, I think I need to redo the patch to remove this artifact. It wasn't the "same" on VT for some reason. Regardless, I'll work on an improved version.
